Bridging Finance Explained: How Bridging Loans Work in the UK (2026 Guide)

Bridging finance is one of the most powerful — and frequently misunderstood — tools available in the UK property finance market. Used correctly, a bridging loan can enable transactions that would otherwise be impossible, move at a speed that conventional mortgage lending cannot match, and bridge the gap between an immediate financial need and a longer-term funding solution.

This guide explains exactly how bridging finance works, what it costs, when it is appropriate, and how Giles Finance can help you access competitive bridging terms through our specialist lending panel.

What Is a Bridging Loan?

A bridging loan is a short-term, property-secured loan designed to bridge a temporary funding gap. It is typically used where a borrower needs immediate access to capital — to complete a property purchase, fund a refurbishment, or release equity — while a longer-term exit strategy, such as a sale or mortgage refinance, is being arranged.

For ground-up builds, Class MA conversions and other projects that need staged drawdowns rather than a single advance, see our development finance service.

Bridging loans are characterised by three key features:

• Speed — a properly structured bridging loan can complete in as little as five to ten working days, compared to six to twelve weeks for a conventional mortgage.
• Short term — loan terms typically run from one to twenty-four months, with interest charged monthly.
• Exit strategy — every bridging loan is underwritten with reference to a clearly defined exit strategy, being the mechanism by which the capital will be repaid at the end of the term.

How Does Interest Work on a Bridging Loan?

Unlike a mortgage, where interest is paid monthly on a reducing balance, bridging loan interest is typically either rolled up or retained from the loan advance:

• Rolled-up interest — interest accrues throughout the loan term and is added to the outstanding balance, repaid in full on exit. No monthly payments are required. This is the most common structure for borrowers who do not wish to service debt monthly.
• Retained interest — the lender deducts the projected interest for the full term from the gross loan advance at completion. The borrower receives a net sum. Any unused interest is typically rebated on early repayment.
• Serviced interest — the borrower makes monthly interest payments as they fall due, similar to a mortgage. This structure may be offered where the borrower has demonstrable monthly income.

Bridging loan interest rates in 2026 typically range from approximately 0.55% to 1.5% per month, depending on loan-to-value, property type, exit strategy quality, and borrower profile. The most competitive rates are generally available for well-secured loans at lower LTVs with a clearly evidenced exit.

What Are Bridging Loans Used For?

Bridging finance is legitimately used across a wide range of property and commercial transactions. The most common applications include:

Property Purchases at Auction

Auction purchases require legal completion within twenty-eight days of the fall of the hammer. A conventional mortgage cannot achieve this timeframe. A bridging loan provides the funds required to complete, with the exit being either a sale or a refinance to a term mortgage once the property has been purchased.

Chain Break Finance

Where a property purchase is delayed due to a broken chain, a bridging loan can enable the buyer to proceed independently of the sale of their existing property, avoiding the loss of a purchase opportunity.

Refurbishment and Development Finance

Bridging loans are widely used to finance light-to-heavy refurbishment of residential and commercial properties, particularly where the property is unmortgageable in its current condition. The exit is typically a refinance to a buy-to-let or commercial mortgage once the works are complete.

Business Cash Flow and Asset Acquisition

Businesses can use bridging finance secured on property to release capital for stock, equipment, or short-term operational requirements, where speed is a priority and a term loan is either unavailable or inappropriate.

Land and Development Sites

Bridging finance is available against land with or without planning permission, making it a common tool for developers seeking to secure a site before development finance is arranged.

First Charge and Second Charge Bridging Loans

A first charge bridging loan is secured as the primary charge against a property — meaning the bridging lender would be first to be repaid from any sale proceeds. First charge lending is available where the property is unencumbered or where any existing mortgage is being simultaneously discharged.

A second charge bridging loan is secured behind an existing first charge mortgage. The bridging lender’s security ranks second in priority. As a result, second charge bridging is viewed as higher risk, and rates are typically marginally higher than first charge equivalents. However, second charge bridging is a useful tool where the borrower does not wish to disturb or redeem an existing mortgage.

The Costs of a Bridging Loan

In addition to the monthly interest charge, borrowers should anticipate the following costs:

• Arrangement fee — typically 1% to 2% of the gross loan amount, payable on completion. Some lenders add this to the loan.
• Exit fee — charged by certain lenders on repayment, ranging from 0% to 1% of the gross loan. Not all lenders charge an exit fee.
• Valuation fee — the lender will instruct an RICS-qualified surveyor. The cost depends on the property value and type.
• Legal fees — the borrower meets both their own legal costs and the lender’s legal costs. Some lenders offer dual representation for straightforward transactions.
• Broker fee — where a broker is used to arrange the facility. Our fees are disclosed at outset.

When calculating the total cost of a bridging loan, always work on a gross basis: include all fees, rolled-up interest for the projected term, and a reasonable contingency for delays. Never assume best-case timing on a time-critical transaction.

Worked example: a £300,000 purchase on a nine-month bridge

Illustrative only. Figures are rounded and do not include valuation, legal or exit fees, which vary by case.

Item	Amount
Purchase price	£300,000
Gross loan at 70% LTV	£210,000
Interest retained: 0.75% per month × 9 months (£1,575 × 9)	£14,175
Arrangement fee at 1% of gross loan	£2,100
Net advance on completion	£193,725
Buyer’s balance to find (purchase price less net advance)	£106,275

Because the interest is retained, nothing is paid monthly during the term. If the property is sold or refinanced in month six, most lenders refund the unused three months of retained interest (£4,725 here), so the true cost falls with a faster exit. If the exit runs past month nine, the lender will charge default interest at a higher rate until redemption, which is why the exit plan is tested so carefully at application.

The same purchase through a buy-to-let mortgage or a commercial mortgage would be far cheaper per month, but neither can complete in time for an auction deadline or lend on a property that is not yet habitable. Bridging buys time; the term mortgage is the exit.

What Is an Exit Strategy — and Why Does It Matter?

A bridging loan is not designed to be a long-term financing solution. It is secured on the basis that the capital will be repaid at a defined point, through a defined mechanism. Lenders will not proceed without a credible exit strategy.

The two most common exit routes are:

• Refinance — the bridging loan is repaid from the proceeds of a term mortgage (buy-to-let, residential, or commercial) arranged on the property after completion or refurbishment.
• Sale — the property is sold and the bridging loan (plus accrued interest and fees) is repaid from the sale proceeds.

Lenders will stress-test the exit. For refinance exits, many lenders require evidence that term mortgage finance is achievable — either a decision in principle from a mortgage lender or a credible professional opinion that the property will meet standard lending criteria on completion. For sale exits, market evidence of comparable properties and realistic sale timescales will be examined.

What happens when the bridging term ends?

A bridging loan is a fixed-term facility. If the agreed exit completes on time, the lender is redeemed in full, any unused retained interest is refunded and the charge is released. Three other outcomes are possible, and each should be planned for before you sign:

• Extension. If the sale or refinance is progressing but needs more time, most lenders will agree a formal extension for a further fee and at a re-agreed rate. This must be requested before the term expires, not after.
• Default interest. Once the term has passed without redemption or an agreed extension, the lender charges default interest, typically a substantial uplift on the standard monthly rate, until the loan is repaid. On a £210,000 loan each additional month of default costs materially more than the £1,575 in the example above.
• Enforcement. Where there is no realistic exit, the lender can appoint a receiver or take possession and sell the security property. This is rare where the exit was properly evidenced at the outset, which is the whole purpose of the lender’s exit assessment.

We check the exit at the start so that none of these becomes necessary. Our guide to bridging loan exit strategies explains what lenders need to see, and our note on auction purchases and the 28-day completion window covers the most time-critical use.
