How much does a bridging loan cost in the UK?

If you’re weighing up how much a bridging loan costs, it’s natural to feel uncertain. Bridging finance pricing is made up of monthly interest plus a series of fees (such as arrangement, valuation, legal and sometimes exit fees). Typical bridging loan interest rates are quoted monthly, and overall bridging finance cost depends on your project, your property and your exit. As the cost of a bridging loan varies case by case, we set out realistic ranges you can expect. This guide explains the bridging loan cost components clearly – what affects pricing, the bridging loan fees to expect, and worked examples to help you benchmark likely outcomes.

What determines the cost of a bridging loan?

Loan amount and loan-to-value (LTV)

Pricing in bridging is fundamentally about risk. A higher loan-to-value (LTV) typically means a higher bridging loan cost because the lender is taking more risk against the property. At lower LTVs, lenders have greater equity protection and generally price more keenly. At higher LTVs, rates may step up, and you may see tighter conditions, larger arrangement fees, or a requirement for additional security. The loan size also matters – very small loans can cost more proportionally due to fixed fees, while very large loans can attract bespoke pricing, sometimes sharper, sometimes with added complexity.

Type of bridging loan (open vs closed)

A closed bridging loan has a defined exit date agreed upfront – often tied to a contract for sale or a committed refinance. A clearer exit tends to reduce perceived risk, which can improve bridging loan interest rates. An open bridging loan has no fixed end date; it offers flexibility but can carry a pricing premium because the lender bears timing uncertainty. Lenders will often look for strong evidence of a realistic timetable even on open terms.

Property type and condition

Mainstream residential property in lettable or saleable condition can attract more competitive bridging finance cost. Non-standard construction, title complexities, short lease terms, or properties requiring heavy refurbishment typically increase risk and therefore price. Where refurbishment is involved, lenders will consider scope, budget, contractor capability, planning consent and the effect of works on value. The more reliable the plan and the more robust the numbers, the better your chance of a competitive outcome.

More specialist projects involving bridge-to-let finance, unmortgageable property finance or bridging finance for refurbishment often require additional scrutiny because of their specialist nature and, as a result, bridging loan rates can be affected. These cases are still perfectly possible to finance, but lender selection becomes increasingly important, as does packaging the application in the right way.

Exit strategy

Exit is everything. Whether you plan to sell or refinance, lenders price based on the certainty and timing of that exit. A chain-free sale with evidence of demand will usually help pricing. A refinance needs to be credible: achievable loan size, acceptable serviceability for the target lender, no anticipated valuation issues, and sufficient time to complete. Poor exit planning is a common reason bridging becomes expensive – delays extend the term, accrue extra monthly interest, and can trigger extension fees. We encourage clients to pressure-test the exit before committing.

Bridging loan interest rates explained

Monthly interest rates (typical ranges)

Bridging loan interest rates are usually quoted per month rather than per annum. The market moves, but as a general guide many mainstream residential deals fall within a broad monthly interest range, while specialist or higher-risk scenarios sit above that. As explained, precise pricing depends on LTV, property type, borrower profile, and exit strength, however in the current UK market, bridging loan interest rates typically range between 0.65% and 1.2% per month, depending on the lender and the specifics of the case. Lower rates are usually reserved for lower loan-to-value cases with a clear, credible exit strategy. Higher rates tend to apply where the risk is greater, such as higher leverage, complex property types or uncertain exits.

Bridging Loan Interest Structures – Rolled Up, Retained and Serviced Interest

With rolled-up interest, monthly interest accrues and is added to the loan, then repaid at exit. This helps cash flow during works or sale, but increases the cost of a bridging loan because you pay interest on the accumulating balance. With serviced interest, you pay the interest each month from your own cash, keeping the loan balance steadier and slightly reducing overall cost. Rolled-up interest often suits projects with no rental income or where liquidity is reserved for works. Serviced interest can suit borrowers with reliable income who want to minimise compounding.

Fees to expect on a bridging loan

One of the most important aspects of bridging finance costs is understanding how interest is charged within the loan and what impact the structure might have to cashflow.

In a rolled up interest structure, interest accrues throughout the term of the loan and is usually repaid at the end when the facility is redeemed. No monthly payments are therefore required, which can help preserve cash flow during the borrowing period. Rolled up interest structures usually work best where the borrower wants to preserve cashflow during the loan term and repay everything at the end. Examples might include a property investment being refurbished to sell or where development units are being retained and a development exit is required until the refinance completes.

Where the loan is based on a retained interest structure the lender calculates the anticipated interest for the loan term at the outset and then sets those funds aside (or withholds those funds) within the facility. Although this structure also removes the requirement for monthly payments, it may reduce the amount of money advanced at completion because the interest has already been accounted for and held back by the lender. Retained interest usually works best where the borrower wants more certainty over the total interest costs and monthly cash flow without requiring monthly payments. Examples might include an auction purchase or a light refurbishment with modest costs.

For a bridging loan with serviced interest, the borrower pays the interest on a monthly basis throughout the term of the loan. This approach can maximise the amount of capital available on day one, but it does require sufficient income or liquidity to meet the ongoing payments. Serviced interest usually works best where the borrower has enough income or some rental cash flow to pay the interest each month. Examples might include where the borrower has income-producing assets such as a property portfolio with sufficient cash flow, or where short-term capital is required by an experienced investor or business.

None of these structures are inherently cheaper than another, the most appropriate approach depends on the purpose of the loan, the borrower’s cash-flow position, the anticipated exit strategy and the amount of capital required at completion. The interest structure is also usually set by the lender based on their products and policies, and not typically negotiable.

Arrangement fees

Most lenders charge an arrangement fee expressed as a percentage of the gross or net loan. A common bridging loan arrangement fee falls within a broad range – usually 1-2% of the loan amount, varying by lender, complexity, and loan size. It’s usually deducted from the loan on completion rather than paid upfront, but this can differ by lender. For larger or more complex cases, a structuring fee might be split between lender and broker, while some lenders incorporate broker fees into the arrangement line. The key is transparency: understand what’s lender, what’s broker, and what’s included.

Exit fees (and when they apply)

The bridging loan exit fee is not universal. Some bridging lenders charge an exit fee, although many do not. Where an exit fee applies, it is typically up to around 1% of the loan amount and payable when the loan is repaid. Exit fees are more common on certain products or at the keener interest-rate end of the market where total return is balanced between rate and fees. Always check how and when it applies – especially if the fee is on purchase price, valuation, loan amount, or gross development value (GDV) on refurb projects. A slightly higher rate with no exit fee can sometimes be cheaper overall.

Valuation, legal, and admin costs

Valuation fees vary by property type, value, location, and whether it’s single-asset or portfolio. Legal costs are case-specific and can include both your solicitor’s fees and the lender’s legal fees; complex titles, lease extensions, or corporate borrowers can push costs up. Some lenders add admin or telegraphic transfer fees, and there may be broker fees depending on the service model. We advise budgeting a contingency for professional costs because unexpected title points or planning queries can add time and fees.

Bridging Loan Net Advance vs Gross Loan

When borrowers are considering using a bridging loan it is important to understand the distinction between the gross loan and the net advance.

The gross loan is the total facility amount approved by the lender, including any fees or charges. Conversely, the net advance is the amount the borrower actually receives after deductions such as retained interest, arrangement fees and other charges have been taken into account.

The distinction is important because a facility can appear attractive on paper at a gross level, yet provide less usable capital than expected on a net basis. For example, a borrower might secure approval for a £500,000 gross loan. If retained interest and lender fees are deducted from the facility at completion, the amount released to the borrower may be significantly lower than the headline figure suggests, for example a £435,000 net advance.

This is especially important for property purchases, auction acquisitions and refurbishment projects where understanding what funds will be available on completion is critical to the transaction. Although the overall gross facility is a measure of how much funding is being offered and paid for, for the reasons above it is often less important than the net advance that the borrower will actually receive. For this reason, borrowers should always ask for a full cost illustration before proceeding with any bridging loan.

When bridging loans can be expensive

Bridging is designed for short-term use. It becomes expensive when projects drift: sales fall through, refurb overruns, planning takes longer than expected. Poor exit planning is the most common driver of unplanned cost – extensions add more months of interest and sometimes extra fees. Conversely, bridging is not inherently expensive when used appropriately: buying at auction where deadlines are fixed, breaking a chain to secure a onward purchase, or funding a refurbishment that creates value quickly. In these scenarios, the bridging loan cost is proportionate to the speed, certainty and value it unlocks.

​We often see clients benefiting where timing is critical. For example, exchanging on a great deal with a discount for fast completion can outweigh the finance cost. The value created or secured by acting quickly is the real benchmark – not just the interest line in isolation.

How to reduce the cost of a bridging loan

Better exit planning is the single biggest lever. Build time buffers into your timeline. Line up the refinance lender or selling agent early. Anticipate valuation hurdles, tenancy issues, or titles needing work, and resolve them before completion where possible.

​A lower LTV can improve bridging loan interest rates and sometimes reduce fees. If you can contribute a little more equity or add additional security, pricing may improve. Keeping the loan size tight (funding what you need and no more) can also trim costs.

​Using a specialist bridging broker helps you navigate lender criteria, structure, and true total cost. We map your case to lenders that suit your property type and exit, compare bridging loan fees transparently, and negotiate where there’s room. The goal is not just a lower headline rate, but the best overall cost of a bridging loan for your situation.

Worked examples: what a bridging loan might cost

These simplified scenarios are for illustration only. They show how typical UK bridging loan interest rates, fees and terms combine to create an approximate overall cost. Figures are indicative and based on common market ranges. We use round numbers for clarity.

Example 1 – Auction purchase

A client buys a £300,000 house at auction requiring light refurbishment. They borrow £210,000 (70% LTV) on a 6‑month term with rolled-up interest.

• Loan amount: £210,000
• Term: 6 months
• Interest type: Rolled-up monthly interest at around 0.8-0.9% per month
• Arrangement fee: 1-2% of the loan amount, added to the loan
• Valuation & legals: Typically a few thousand pounds for a single residential asset

​Interest accrues monthly and is rolled up over the 6-month term, increasing the redemption balance. In addition, an arrangement fee of £2,100 – £4,200 is applied, along with valuation and legal costs.

​Provided the property sells on time, no extension or exit fees apply. While the monthly interest is higher than a buy-to-let mortgage, the speed and certainty required for an auction purchase often justify the short-term cost.

Example 2 – Refurbishment project

A semi-detached property valued at £500,000 requires a structured refurbishment. The client borrows £300,000 at 60% LTV for 9 months, servicing interest monthly and planning to refinance onto a buy-to-let mortgage once works are complete.

• Loan amount: £300,000
• Term: 9 months
• Interest type: Serviced interest at around 0.7–0.85% per month
• Arrangement fee: Typically around 1–1.5% of the loan amount
• Exit fee: None on this product
• Valuation & legals: Higher than standard, due to works schedule and monitoring

​Interest is paid monthly based on the outstanding loan balance, totalling the monthly rate multiplied by £300,000 over 9 months. An arrangement fee of approximately £3,000–£4,500 applies, alongside valuation and legal costs.

​Because interest is serviced rather than rolled up, the redemption balance remains lower than in a rolled-up structure. If the refinance is delayed, an extension fee may apply, which is why refinance planning is critical in refurbishment projects.

Example 3 – Property flip (purchase and resale)

An investor purchases a residential property below market value with the intention of carrying out light cosmetic works and reselling quickly. The purchase price is £350,000 and the investor borrows £245,000 (70% LTV) on a 6-month term with rolled-up interest.

• Loan amount: £245,000
• Term: 6 months
• Interest type: Rolled-up interest at around 0.75–0.9% per month
• Arrangement fee: Typically around 1–2% of the loan amount
• Exit fee: None on this product
• Valuation & legals: Standard residential valuation and legal costs

​Interest accrues monthly and is rolled up over the 6-month term, increasing the redemption balance. An arrangement fee of approximately £2,450–£4,900 applies, alongside valuation and legal costs.

​Because the loan is short-term and the exit is a sale rather than a refinance, the overall cost depends heavily on how quickly the property is resold. Delays in completion extend the interest period and increase total cost, which is why realistic resale timelines are critical in property flip projects.

Is a bridging loan right for you?

Bridging suits borrowers who need speed, certainty, or flexibility: auction buyers, investors executing value-add refurbishments, homeowners solving a chain break, or developers requiring a short window of funding before sale or refinance. It’s not always the right option if your timeline is uncertain, your exit depends on optimistic assumptions, or a conventional mortgage could accommodate your needs with a little patience. We’re candid about that. Sometimes the most cost-effective advice is to pursue an alternative.
