Bridging Finance Glossary
Bridging finance comes with its own vocabulary. Terms are used with precision by lenders, valuers and solicitors, but the same phrase can mean different things depending on the lender, the transaction type or the facility structure. For borrowers comparing facilities for the first time, that inconsistency creates real risk: misreading an interest structure or an LTV metric can materially affect your understanding of cost and leverage.
This glossary is intended to cut through that ambiguity. It covers the terminology commonly used across UK bridging loans, short-term property finance and specialist lending, including terms that overlap with development finance and commercial lending. Where a concept works differently across lender types, we have noted it.
Whether you are raising auction finance under time pressure, structuring a development exit or comparing first and second charge options, understanding the language of bridging finance puts you in a stronger position when negotiating terms and reviewing offers.
Structures and terminology do vary between lenders. This glossary reflects the most widely used conventions in the UK market, but you should always confirm specific definitions with your lender or broker before proceeding with a facility.

Interest & Fees
Rolled-Up Interest
What it is:
With rolled-up interest, no monthly payments are made during the loan term. Instead, the interest accrues on the outstanding balance each month and is added to the loan. The full interest amount, plus the original principal, is repaid in a single payment when the loan is redeemed.
Why it matters:
Rolled-up interest is the default structure for many bridging loans because it preserves cash flow during the loan period, which suits investors and developers who are not generating income from the security property. The downside is that interest compounds over the term, so the longer the loan runs, the more expensive it becomes. When comparing facilities, always check whether rates are quoted on a simple or compound basis.
Retained Interest
What it is:
With a retained interest structure, the lender deducts the full projected interest cost upfront from the loan advance. The borrower receives a net advance after that deduction, but the gross loan (and the LTV calculation) is based on the higher, full figure.
Why it matters:
Retained interest affects how much cash you actually receive on day one. A facility marketed at 70% LTV with retained interest will deliver a materially lower net advance than a 70% rolled-up facility. It also means you are effectively paying interest on interest you have not yet incurred, since the full term is deducted at the outset. Understanding this distinction is important when comparing loan offers and modelling project cash flow.

Serviced Interest
What it is:
A serviced interest facility requires the borrower to make monthly interest payments throughout the loan term. The principal is repaid at the end. This mirrors the payment structure of a conventional mortgage.
Why it matters:
Serviced interest is less common in bridging but suits borrowers who have sufficient income or cash flow and want to reduce their overall interest cost by not allowing it to compound. Some lenders offer a lower rate for serviced facilities than for rolled-up equivalents, reflecting the reduced risk to them of receiving regular payments. This is closer to the payment structure of an interest-only mortgage, with interest paid monthly and the capital repaid at the end.
Related:
Arrangement Fee
What it is:
The arrangement fee is the lender's upfront charge for setting up the facility. It is typically expressed as a percentage of the gross loan, most commonly between 1% and 2%, though this varies significantly across the market. It may be added to the loan or deducted from the advance.
Why it matters:
Arrangement fees are a meaningful part of the true cost of a bridging loan, particularly on short-term facilities where the interest period is limited. A lower headline rate with a higher arrangement fee can easily be more expensive overall than a higher rate with a lower fee. Always model the total cost including all fees across your expected loan term, not just the monthly rate.
Related:
Exit Fee
What it is:
An exit fee is a charge payable when the loan is redeemed. Like the arrangement fee, it is usually expressed as a percentage of the gross loan. Not all bridging lenders charge an exit fee, and its presence or absence can significantly affect the total cost of a facility.
Why it matters:
Exit fees are easy to overlook when focusing on rate and arrangement costs, but they can add considerably to the total cost of borrowing, particularly on larger loans. Some lenders use a stepped structure where the exit fee increases the longer the loan runs. Always factor the exit fee into your total cost of funds calculation, especially if you anticipate the loan running longer than planned.
Default Interest
What it is:
Default interest is an elevated rate charged when a borrower fails to repay the loan by its agreed maturity date. It typically sits materially above the contractual rate, sometimes double or more, and applies from the date the loan enters default.
Why it matters:
Default interest can accumulate rapidly on large bridging facilities and significantly erode equity in the security property if a loan runs into difficulty. Lenders use it to incentivise repayment and compensate for the increased risk and management cost of an overrunning loan. If you are approaching loan maturity without a clear exit in place, speaking to your lender early is always preferable to entering default. Some lenders will agree a short extension rather than trigger default provisions.
Related:
Non-Utilisation Fee
What it is:
A non-utilisation fee (sometimes called a commitment fee) is charged on undrawn portions of a facility where the lender has committed capital but the borrower has not yet drawn it down. It is more commonly seen in development finance facilities than standard bridging loans.
Why it matters:
In tranched facilities where funds are drawn in stages, a non-utilisation fee compensates the lender for holding committed capital ready to deploy. For borrowers, it adds to the effective cost of a facility even before funds are drawn. Where a non-utilisation fee applies, it should be factored into your cost modelling alongside interest and arrangement fees.
Redemption Figure
What it is:
The redemption figure is the total amount required to repay a bridging loan in full on a given date. It includes the outstanding principal, all accrued or retained interest to that date, any outstanding fees, and any early repayment or exit charges specified in the facility agreement.
Why it matters:
The redemption figure is the number that matters most at the point of exit. It is not always easy to calculate from a term sheet alone, particularly with retained or rolled-up interest structures. Lenders will provide a formal redemption statement on request, and you should always obtain one before exchanging on a sale or refinancing into a long-term product. Leaving insufficient time to request and act on a redemption statement can cause delays at completion.

Loan Structures and Facility Types
Open Bridging Loan
What it is:
An open bridging loan has no fixed repayment date. The borrower is expected to repay when their exit event occurs (such as a property sale or refinance) but is not contractually locked to a specific date. Most open bridges still have a maximum term, typically 12 to 24 months.
Why it matters:
Open bridging loans suit situations where the exit timeline is uncertain, for example where a sale is in solicitors' hands but exchange has not yet occurred. They carry more risk for the lender than closed loans, which is often reflected in the pricing. Borrowers should still have a credible, near-term exit strategy in place: the absence of a fixed repayment date is not an invitation to extend indefinitely.
Related:
Closed Bridging Loan
What it is:
A closed bridging loan has a defined, evidenced repayment route and expected repayment date. This may be tied to an exchanged property sale, a confirmed refinance or another clearly documented exit event.
Why it matters:
Closed bridging loans are generally viewed as lower risk than open bridging loans because the lender has greater confidence in how and when the facility will be repaid. An exchanged sale is the strongest example, but it is not the only possible closed-bridge scenario. If the confirmed exit falls through, the loan may move onto default terms or require immediate renegotiation.

First Charge Bridging Loan
What it is:
A first charge bridging loan is secured by a first legal charge over the property used as security. This gives the lender priority over all other creditors in the event of enforcement: if the property is sold to recover the debt, the first charge lender is repaid before any other secured parties.
Why it matters:
First charge bridging is the most common structure in the market and carries the lowest risk for lenders, which is reflected in keener pricing and higher available LTVs compared with second charge facilities. Most lenders will only lend on a first charge basis. If there is an existing mortgage or charge on the security property, it will generally need to be repaid before or as part of the bridging transaction.
Second Charge Bridging Loan
What it is:
A second charge bridging loan sits behind an existing first charge on the security property. The second charge lender has a subordinate claim on the proceeds in any enforcement scenario, meaning they are repaid only after the first charge lender has recovered their debt in full.
Why it matters:
Second charge bridging is typically used where the borrower cannot or does not want to disturb an existing first charge (for example, where a favourable mortgage rate or early repayment charge makes redemption unattractive). Because the lender is in a subordinate position, rates and fees are higher and maximum LTVs are lower. Lenders will often require consent from the first charge holder before proceeding.
Regulated Bridging Loan
What it is:
A regulated bridging loan is one that falls within UK mortgage regulation because the security property is, or will be, occupied by the borrower or an immediate family member.
Why it matters:
Regulated bridging loans carry additional consumer protections, including stricter affordability requirements and specific disclosure obligations. Lenders operating in this space must be FCA-authorised for regulated mortgage activity. The regulatory overhead tends to mean fewer lenders are active in this market and processing times can be longer. If there is any ambiguity about whether a transaction is regulated, your broker or lender should confirm the regulatory position before proceeding.
Unregulated Bridging Loan
What it is:
An unregulated bridging loan falls outside UK mortgage regulation, typically because the security property is an investment, development or commercial asset rather than the borrower’s primary residence. A large proportion of UK bridging transactions are unregulated.
Why it matters:
Unregulated bridging facilities generally move faster and with more flexibility than regulated equivalents, because lenders are not bound by the same affordability and disclosure rules. The absence of regulatory protection does not mean borrowers should be less rigorous in their due diligence: the terms of an unregulated facility can be complex and the consequences of default are serious. Independent legal advice is always recommended.
Bridge-to-Let
What it is:
A bridge-to-let facility is a bridging loan structured with a built-in route to a buy-to-let mortgage at the end of the term. The bridging lender and a partner buy-to-let lender agree terms upfront, allowing the borrower to move from the bridge to the long-term product once the property is ready to be let.
Why it matters:
Bridge-to-let is well suited to investors acquiring properties that are not immediately mortgageable, for example because they are uninhabitable, require refurbishment or have a short lease. The dual-product structure gives certainty of exit from day one, which removes one of the key risks of bridging finance. Rates across both elements of the facility should be modelled carefully, as the overall cost involves both the bridging element and the buy-to-let mortgage terms.
Re-Bridging
What it is:
Re-bridging refers to replacing an existing bridging loan with a new bridging facility, typically because the original loan has reached or is approaching maturity and the planned exit has not yet been achieved. It is effectively a refinance from one bridge to another.
Why it matters:
Re-bridging is usually a signal that something in the original transaction has not gone to plan: a sale that has not exchanged, a refinance that has fallen through or a refurbishment that has overrun. While it provides breathing space, the costs of re-bridging (arrangement fees, legal costs and potentially a higher rate) can be significant. It should be considered a contingency option rather than a planned exit route. Lenders will assess the new application on its current merits, including updated valuations.

Lending and Valuation Metrics
Loan to Value (LTV)
What it is:
Loan to value expresses the loan amount as a percentage of the property's value. In bridging finance, LTV is typically calculated against the current market value of the security asset, though lenders vary in whether they use the gross loan or net advance in their calculation.
Why it matters:
LTV is the single most important metric for assessing how much you can borrow against a given asset. Higher LTVs mean more leverage, but they also attract higher rates and reduce the lender's margin for error in an enforcement scenario. Most bridging lenders will go to 70-75% LTV on standard residential security, with lower limits on commercial or higher-risk assets. Always clarify whether a quoted LTV is gross or net, as the difference meaningfully affects how much you actually receive.
Gross Loan
What it is:
The gross loan is the total facility amount before any deductions. In a retained interest structure, it includes the interest that has been deducted from the advance. In a rolled-up structure, it represents the loan principal only, with interest accruing separately. LTV calculations are typically based on the gross loan figure.
Why it matters:
Confusing gross and net loan figures is one of the most common errors borrowers make when comparing bridging offers. Two facilities at the same LTV can produce materially different net advances depending on their interest structures. Always confirm whether a quoted loan figure is gross or net, and model both the amount you will actually receive and the total repayment obligation at exit.
Related:
Net Advance
What it is:
The net advance is the amount the borrower actually receives after deductions have been made from the gross loan. These deductions may include retained interest, arrangement fees, legal fees, valuation fees and other costs not funded separately.
Why it matters:
The net advance is the figure that matters for cash flow planning. It determines how much capital you have available on day one for the deposit, acquisition costs, refurbishment budget or other project requirements. Where a facility has a significant retained interest deduction, the net advance can be materially lower than the headline loan figure. Always work from the net advance when modelling whether a facility actually works for your transaction.

Day-One Value
What it is:
Day-one value refers to the current open market value of the security property at the point of loan drawdown, before any refurbishment, development or planning uplift has been applied. It forms the basis of the LTV calculation for the initial advance in most bridging and refurbishment finance facilities.
Why it matters:
Lenders use the day-one value to determine how much they will lend against a property in its current state. For properties requiring significant work or where the expectation is for value to be created through planning permission, the day-one value can be considerably lower than the anticipated end value (GDV), which limits the initial advance. Some lenders will lend against a blended value or make advances in tranches based on project progress, but the day-one figure remains the anchor for the opening position.
Lenders use the day-one value to determine how much they will lend against a property in its current state. For properties requiring significant work, the day-one value can be considerably lower than the anticipated end value (GDV), which limits the initial advance. Some lenders will lend against a blended value or make tranched advances based on project progress, but the day-one figure remains the anchor for the opening position.
Gross Development Value (GDV)
What it is:
Gross development value is the projected total open market value of a property or development scheme on completion, assuming all planned works have been carried out to the required standard. It is used by lenders to assess the end-state value of a project and the feasibility of the exit.
Why it matters:
GDV is the critical metric in development and heavy refurbishment lending because it determines the maximum loan available under LTGDV constraints and gives the lender confidence in the exit. An optimistic GDV assumption inflates apparent loan headroom and can lead to underfunding. Lenders will typically appoint their own RICS-registered valuer to produce an independent GDV assessment, and this figure, not the borrower's own estimate, will be used in lending calculations.
Loan to Gross Development Value (LTGDV)
What it is:
LTGDV expresses the total loan amount as a percentage of the gross development value. It is the primary leverage metric in development finance and development exit lending, alongside loan to cost. A typical maximum in the market is 65-70% LTGDV, though this varies by lender and project type.
Why it matters:
LTGDV constrains the maximum loan available on a project, regardless of cost or other metrics. Even if a borrower can demonstrate a solid cost base and credible GDV, lenders will not advance beyond their LTGDV ceiling because it represents their exposure relative to the expected end value. Where planning has not been granted, lenders may apply a conservative figure or decline to lend against GDV at all, which is why specialist planning gain finance facilities are often structured around existing use value rather than projected uplift.
Loan to Cost (LTC)
What it is:
Loan to cost measures the loan amount as a percentage of the total project cost, including land or acquisition price, construction costs and professional fees. It is used alongside LTGDV to establish the maximum facility available on development and refurbishment transactions.
Why it matters:
LTC is a useful check on whether a project is adequately funded relative to its cost base. A lender's LTC limit effectively requires borrowers to contribute a minimum level of equity to the project. High LTC ratios can signal that a borrower has little skin in the game, which lenders will view cautiously. In complex transactions, LTC and LTGDV constraints may produce different loan ceilings, and the lower of the two will determine the actual facility amount.
Loan Term
What it is:
The loan term is the agreed period for which the bridging facility is available, from the date of first drawdown to the contractual repayment date. Standard bridging loan terms range from one month to 24 months, though some lenders offer longer terms on specific product types.
Why it matters:
The loan term affects the total interest cost (whether rolled-up or retained) and the pressure on the borrower to execute their exit strategy within a defined window. Shorter terms carry lower total interest but more execution risk. Over-estimating how quickly a project will complete or a sale will proceed is a common cause of bridging loans approaching maturity without a clear exit. Building a sensible buffer into your planned loan term is a basic risk management step.

Security, Legal and Underwriting
Personal Guarantee
What it is:
A personal guarantee is a legally binding commitment by an individual (usually the director or principal behind a borrowing entity) to repay the loan if the borrowing company defaults. It makes the guarantor personally liable for the debt, separate from any limited liability protection their company structure would otherwise provide.
Why it matters:
Personal guarantees are standard in many bridging transactions, particularly where the borrower is an SPV or limited company. Lenders use them to close the gap between the property security and the loan amount, and to ensure that the principals have real skin in the game. Guarantees can be unlimited or capped at a specific figure. The implications of signing a personal guarantee are serious and independent legal advice should always be obtained before doing so.
Related:
Debenture
What it is:
A debenture is a legal instrument that allows a lender to take a fixed and floating charge over the assets of a company, including property, equipment, cash and receivables. It gives the lender the ability to appoint an administrator or receiver over the company's assets in the event of default.
Why it matters:
Debentures are commonly required by bridging lenders when lending to corporate borrowers, in addition to (or instead of) a personal guarantee. They provide security over the company's broader asset base rather than just the property. For borrowers, granting a debenture gives the lender significant enforcement powers and should not be agreed without understanding the full scope of what is being charged.
Related:
Legal Charge
What it is:
A legal charge is the formal security instrument that gives a lender rights over a property. When registered at HM Land Registry, it prevents the owner from selling or refinancing the property without the lender's consent. First and second charge positions refer to the priority order in which lenders rank in the event of enforcement.
Why it matters:
The legal charge is the foundation of all secured property lending. Without a registered charge, the lender has no secured claim on the asset. In bridging transactions, speed of legal charge registration can affect loan drawdown timelines, particularly on auction purchases where completion deadlines are tight. Solicitors acting for the lender will typically require searches, title confirmation and a clean report on title before registering the charge and releasing funds.
Title Defect
What it is:
A title defect is any issue with the legal ownership or encumbrance position of a property that creates uncertainty or restricts the lender's ability to take clean security. Common examples include missing title documents, restrictive covenants, boundary disputes, chancel repair liability or unresolved ownership claims.
Why it matters:
Title defects can delay or prevent a bridging loan from proceeding, since lenders will not advance against property where the security is legally compromised. Some defects can be resolved with title indemnity insurance, which provides the lender with protection against the financial consequences of the defect crystallising. Others require formal legal resolution before any advance is possible. Early instruction of specialist solicitors and a thorough title review can surface these issues before they become deal-breaking problems at the eleventh hour.
Related:
Vacant Possession
What it is:
Vacant possession means that a property is available to be handed over free from any occupants, tenants or personal belongings at the point of sale or loan drawdown. A property with sitting tenants does not have vacant possession unless those tenants have vacated or have been formally served notice.
Why it matters:
Lenders treat vacant possession as a key factor in assessing both the value and the marketability of a security property. A property with problematic tenancies, unlawful occupants or squatters may be significantly harder to sell under enforcement, which directly affects the lender's risk assessment. Where vacant possession cannot be confirmed, lenders may decline, reduce their advance or require additional security to compensate for the increased exit risk.
Asset Manager
What it is:
In the context of bridging and development finance, an asset manager (sometimes called a monitoring surveyor) is appointed by the lender to oversee projects where funds are released in tranches based on construction or refurbishment progress. They conduct site visits, certify drawdown requests and report to the lender on project status.
Why it matters:
Asset managers act as the lender's eyes on site and provide the quality and progress assurance needed before releasing further funds. Their fees are typically charged to the borrower and should be budgeted for alongside professional fees and finance costs. Delays in asset manager sign-off on a drawdown request can affect cash flow during a build programme. Selecting a contractor with a clear audit trail of completed works and valuations makes the drawdown process considerably smoother.
Underwriter
What it is:
An underwriter is the individual or team within a lending organisation responsible for assessing and approving loan applications. They review the borrower's profile, the security property, the exit strategy and all supporting documentation before making a lending decision.
Why it matters:
The underwriter's assessment is where deals are won or lost. Understanding what underwriters prioritise (a credible exit, proven borrower track record, clean title and realistic valuations) allows borrowers and brokers to present cases more effectively. Some bridging lenders operate with credit committees rather than individual underwriters, particularly for larger or more complex transactions. Building a relationship with lenders and brokers who understand your deal type can shorten the underwriting process significantly.
Related:
Exit Strategy
What it is:
The exit strategy is the borrower's plan for repaying the bridging loan. Common exits include a property sale, refinance onto a buy-to-let or commercial mortgage, repayment from the proceeds of a separate asset sale, or completion and sale of a development scheme.
Why it matters:
The exit strategy is the most scrutinised element of any bridging application because the entire structure of a short-term loan depends on the borrower's ability to repay within the agreed term. Lenders look for exits that are realistic, verifiable and not wholly dependent on a single uncertain event. A dual exit (for example, a sale if refinance is not available) strengthens the application considerably. Weak or vague exits are the most common reason for bridging applications being declined or offered at reduced leverage.
Property and Transaction Types
Auction Finance
What it is:
Auction finance is a bridging loan structured to meet the strict completion timelines that apply after a property is purchased at auction. In England and Wales, auction purchases typically require completion within 28 days of the auction, leaving very limited time to arrange funding.
Why it matters:
Speed is the defining requirement in auction finance: a lender unable to complete within the 28-day window is commercially useless regardless of their headline rate. Borrowers should arrange an agreement in principle before the auction takes place and have their legal team ready to instruct on the day of purchase. Specialist auction finance lenders and brokers understand the process and can often complete within 5-10 working days where the deal is straightforward. Failure to complete on time results in forfeiture of the deposit, typically 10% of the purchase price.

Refurbishment Finance
What it is:
Refurbishment finance is a bridging or short-term facility designed for properties requiring improvement or repair work before they can be occupied, let or sold. It sits on a spectrum from light cosmetic works at one end to structural alterations and conversions at the other.
Why it matters:
Lenders categorise refurbishment projects differently, and the distinction between light and heavy refurbishment affects both the maximum LTV available and whether an asset manager will be appointed to oversee works. Light refurbishment (decoration, new kitchens and bathrooms, landscaping) typically uses a standard bridging structure with a single advance. Heavier programmes that involve structural works, extensions or change of use usually require a tranched facility, with funds released in stages against certified progress.
Heavy Refurbishment
What it is:
Heavy refurbishment refers to projects involving significant structural works, such as extensions, conversions, roof replacements, or changes of use. It is distinguished from light refurbishment by the scale of works, the involvement of planning or building regulations, and the greater complexity of the funding structure.
Why it matters:
Heavy refurbishment projects are closer to development finance than standard bridging, and lenders assess them on similar metrics, including day-one value, GDV, LTC and LTGDV. Funds are typically released in tranches following sign-off from an appointed asset manager. Borrowers should have a detailed schedule of works, a fixed-price contract (or robust contingency) and a clear planning position before approaching lenders. Underestimating both the cost and the duration of heavy refurbishment projects is one of the most consistent causes of bridging loans overrunning.
Semi-Commercial Property
What it is:
A semi-commercial property (also called mixed-use) is one that combines residential and commercial elements within the same building, for example a ground-floor retail unit with residential flats above. It does not fall neatly into either pure residential or pure commercial lending categories.
Why it matters:
Semi-commercial assets can be more complex to fund than single-use properties because lenders need to assess both the commercial and residential elements, their relative income contribution and the impact on marketability and value. Fewer lenders are active in the semi-commercial bridging market, and those that are will typically apply more conservative LTVs than on pure residential security. The nature of the commercial tenant and the lease terms are closely scrutinised.
Unmortgageable Property
What it is:
An unmortgageable property is one that does not meet the lending criteria of mainstream mortgage providers, typically because of structural issues, lack of utilities, very short lease, non-standard construction, uninhabitability or title problems. It may still be fundable through specialist bridging or short-term finance.
Why it matters:
Bridging lenders have considerably more flexibility than high street mortgage lenders in what they will accept as security, because they are lending on a short-term basis with a clear exit in mind rather than underwriting a long-term debt. Properties that are uninhabitable, have structural defects, are under a compulsory purchase order or have unusual ownership structures can all, in some circumstances, be funded through bridging. The key question is always whether a credible exit exists: if no mainstream lender will ever touch the property and it cannot be sold to an owner-occupier, even bridging lenders will be cautious.
Related:
Development Exit Finance
What it is:
Development exit finance is a bridging facility used to refinance a development loan once the main construction phase is complete but before the units have been sold or the longer-term refinance has been arranged. It allows the borrower to repay the development lender, often at a lower rate, while the sales or lettings programme completes.
Why it matters:
Development exit loans typically benefit from a higher LTV than the original development facility, because the completed scheme has a measurable GDV rather than a projected one. They also tend to carry lower rates than development finance because the construction risk has been removed. For developers whose build programmes are complete but whose sales are taking longer than anticipated, development exit provides a cost-effective way to manage the transition between development and income-producing or vacant property.
Planning Gain
What it is:
Planning gain refers to the increase in a property's value that results from obtaining planning permission for a more valuable use. For example, securing consent to convert an office building into residential flats, or obtaining permission to build additional units on a site, can substantially uplift the underlying asset value.
Why it matters:
Planning gain is a significant driver of value creation in property investment and development, and planning gain finance is frequently used to fund the acquisition of assets with planning potential while the consent is sought. Lenders will not usually lend against anticipated planning values before consent is granted: the day-one advance is based on existing use value only. Once planning is secured, the uplifted value can support a refinance or a development finance facility on more favourable terms. The risk of planning being refused or granted in a diluted form is always the borrower's to bear.
