What Is Bridging Finance? A Plain-English UK Guide

A bridging loan is a short-term secured loan, typically lasting between one month and 24 months. It is secured against a property — either the property being purchased or another asset — and is designed to provide fast access to capital while a longer-term solution is arranged or a property transaction completes.

Unlike a residential mortgage, bridging loans are assessed primarily on the value of the security (the property) and the exit strategy — the credible plan for repaying the loan at the end of the term. Monthly repayments may be required, but many bridging loans allow interest to be rolled up and added to the outstanding balance, with the full amount repaid from the exit strategy proceeds.

Bridging finance is offered by specialist lenders rather than high street banks. Some products are regulated by the Financial Conduct Authority; others are not. The regulatory status depends on whether the security is or will be used as a dwelling by the borrower or their immediate family.

Bridging finance covers a wide range of situations where conventional lending is too slow, too inflexible, or unavailable. Common uses include:

• Buying at auction: Auction purchases require completion in 28 days — too fast for a standard mortgage. Bridging finance can complete in days.
• Breaking a property chain: Buying a new property before the sale of an existing one completes.
• Uninhabitable or unmortgageable properties: Standard mortgages are unavailable on properties without a working kitchen or bathroom. Bridging finance is not subject to the same habitability requirements.
• Property development or refurbishment: Funding the purchase and works on a property before refinancing onto a development loan or mortgage on completion.
• Planning gain: Purchasing land or property before planning permission is granted, with the intention of refinancing once consent is obtained and value has increased.

The distinction between regulated and unregulated bridging finance is important because it determines what consumer protections apply.

Regulated bridging finance applies when the loan is secured against a property that is — or will be — used as the borrower's main home or family member's home. Regulated bridging loans must comply with FCA mortgage rules, including affordability and conduct requirements. Lenders must be FCA-authorised.

Unregulated bridging finance applies when the security is an investment property, commercial property, land, or any property not used as the borrower's home. FCA conduct rules do not apply in the same way. This category covers the majority of bridging loans used for property investment and development.

Whether your bridging loan is regulated or unregulated affects the consumer protections available to you and the recourse you have if things go wrong. Always confirm the regulatory status of any loan with the lender or broker before proceeding.

Bridging loan interest is usually quoted as a monthly rate rather than an annual rate. Monthly rates typically range from around 0.4% to 1.5% per month depending on the loan-to-value, the property type, the lender, and the borrower's circumstances. At 0.75% per month, the annualised cost is approximately 9% — significantly higher than most mortgage rates.

Interest can be structured in three main ways:

• Monthly payments: Interest is paid each month, keeping the outstanding balance stable.
• Retained interest: The expected total interest for the full term is deducted from the loan at the outset — reducing the net amount received.
• Rolled-up interest: Interest is added to the outstanding balance each month and repaid in full alongside the capital at the end of the term.

Each structure has different cash flow implications. Rolled-up interest requires no monthly payments but results in a larger total repayment at the end.

The exit strategy is the lender's primary concern when assessing a bridging loan application. It is the credible plan for repaying the full outstanding balance — capital plus interest — at the end of the term. Without a clear and achievable exit strategy, no reputable lender will advance bridging finance.

Common exit strategies include:

• Sale of the bridged property or another property
• Refinancing onto a buy-to-let mortgage, commercial mortgage, or development finance
• Receipt of funds from another source — an inheritance, business sale, or investment realisation
• Sale of the development following completion of works

The exit strategy must be realistic and evidenced. A lender will want to understand the timeline, the assumptions behind the exit, and what the contingency is if the primary exit route does not deliver on schedule.

Bridging finance is significantly more expensive than standard mortgage lending. The full cost includes:

• Interest: Typically 0.4%–1.5% per month on the outstanding balance
• Arrangement fee: Usually 1–2% of the loan amount, charged by the lender
• Broker fee: If arranged through a broker, typically 1–2% of the loan amount
• Valuation fee: An independent survey of the security property
• Legal fees: Both the lender's and borrower's solicitors
• Exit fee: Some lenders charge an exit or redemption fee on repayment — typically 1% of the loan

On a £300,000 bridging loan over 6 months at 0.75%/month, the total interest cost alone is approximately £13,700. Adding arrangement and other fees, the total cost could easily reach £20,000–£25,000 for a relatively short-term loan.

Bridging lenders assess the loan amount as a percentage of the property's value — the loan-to-value (LTV). Most bridging lenders will lend up to 70–75% of the open market value (OMV) of the security on residential properties, and somewhat lower on commercial or development properties.

Some lenders calculate LTV against the gross development value (GDV) — the expected value after works — rather than the current value. This can allow higher loan amounts for refurbishment or development projects, though the terms reflect the higher risk involved.

A lower LTV typically attracts a lower interest rate. Providing additional security — a second property as cross-collateral — can increase the loan amount available or improve the rate.

Speed is one of bridging finance's main advantages over conventional lending. In straightforward cases with an experienced broker, simple legal work, and a cooperative lender, bridging finance can complete in as little as 3–5 working days. More complex cases — involving multiple securities, complex legal structures, or detailed development proposals — typically take 2–4 weeks.

The speed of completion depends significantly on the speed of the legal process, the valuation, and the borrower's responsiveness in providing information. Choosing a lender and broker with a strong track record of fast completions, and having all documents prepared in advance, reduces the timeline.

Bridging lenders are generally more flexible on credit history than mainstream mortgage lenders. Because the loan is primarily secured against property rather than assessed on income and credit score, borrowers with adverse credit — including CCJs, defaults, or previous bankruptcy — may still be able to access bridging finance, depending on the lender and the LTV.

However, adverse credit typically results in higher rates and lower maximum LTVs. The strength of the security property and the credibility of the exit strategy carry more weight than credit history in many bridging loan decisions, though credit history is still reviewed as part of the overall assessment.

Bridging finance is a powerful but expensive tool. It is appropriate when speed is essential, when conventional lending is unavailable or too inflexible, and when the cost is justified by the purpose. It is not appropriate as a long-term funding solution — it is designed to bridge a specific, time-limited gap.

Before committing to bridging finance, ensure you have a clearly evidenced exit strategy, have modelled the total cost (including all fees and interest) against the benefit of proceeding, and have sought professional advice from an FCA-authorised broker.
