Bridging finance is one of the most flexible and powerful tools in UK property — but it's also one of the most misunderstood. People hear "short-term loan" and "high interest rate" and assume it's a last resort. In reality, bridging loans are used every day by sophisticated property investors, developers, and businesses to move quickly, unlock opportunities, and solve problems that mainstream mortgage lenders simply can't address. This guide explains exactly how bridging finance works, what it costs, and when it makes commercial sense.
A bridging loan is a short-term secured loan — typically 1 to 18 months — that uses property as security. It "bridges" a financial gap between an immediate need for funds and a future event that will provide the money to repay it. That future event might be the sale of a property, the refinance onto a term mortgage, the completion of a refurbishment, or the grant of planning permission.
Unlike a mortgage, which is designed to be held for years, a bridging loan is explicitly temporary. The lender's primary concern is not your income or credit score (though they're relevant) — it's the value of the security property and the credibility of the exit strategy. Can you repay the loan, and how?
The most important classification in bridging finance is whether the loan is open or closed:
| Type | Definition | Typical Rate | Max Term |
|---|---|---|---|
| Closed bridge | Fixed exit date confirmed — e.g. exchange of contracts on sale | Lower | As agreed |
| Open bridge | Exit plan exists but no fixed repayment date | Slightly higher | 12 months typically |
A closed bridge carries less risk for the lender — they know exactly when they'll be repaid. An open bridge is more flexible, suitable when the exit timeline isn't fixed (e.g. waiting for planning, marketing a property for sale). Most commercial bridging loans are open.
The mechanics are straightforward once you understand the components:
You (or your broker) approach a lender with the property details, LTV required, exit strategy, and any supporting information. Lenders issue a Decision in Principle (DIP) — typically within hours for straightforward cases.
An independent RICS valuer inspects the property and provides a formal valuation. Some lenders use desktop or drive-by valuations for low-risk residential cases, speeding up the process.
Solicitors review title, conduct searches, and prepare the facility documentation. Both you and the lender have solicitors — both sets of costs are paid by you.
The loan completes. Funds are released (less deducted fees). From this point, monthly interest accrues on the outstanding balance.
You repay the full loan plus accrued interest when the exit event occurs — property sale, refinance, or other agreed event. The lender releases their charge and the matter is closed.
| Cost | Typical Range |
|---|---|
| Monthly interest rate | 0.55% – 1.25%/month |
| Arrangement fee | 1% – 2% of loan |
| Exit fee | 0% – 1% (not all lenders) |
| Valuation fee | £500 – £2,000 |
| Legal fees (both sides) | £2,500 – £5,000 |
Interest is most commonly rolled — added to the loan balance each month rather than paid from your own cash. This means no monthly outgoings, but the balance grows each month. On exit, you repay the original loan plus all accrued interest in one lump sum.
💡 Worked example: £500,000 bridging loan at 0.75%/month over 6 months with rolled interest. Monthly interest: £3,750. After 6 months, balance approximately £523,000. Add arrangement fee (1.5% = £7,500) and legal/valuation costs (~£4,000). Total repayment: approx £527,000. Total cost of finance: ~£34,500 (6.9% of the original loan).
The charge position determines where the bridging lender sits in the repayment hierarchy if the property is sold:
You've found your next purchase but your current property hasn't sold yet. A bridging loan funds the purchase, the chain completes, and the bridge is repaid when your existing property sells.
Auction completions are required within 28 days — impossible with a standard mortgage. Bridging loans complete in 5–14 days, making auction buying viable. Many investors arrange a Decision in Principle before bidding.
A property that needs significant work won't be mortgageable in its current state. A bridging loan funds the purchase and renovation, with the exit onto a standard mortgage or sale once works are complete.
Purchase land or property at pre-planning value, secure planning permission, and either sell at a significant uplift or refinance onto development finance to build. The bridging loan funds the holding period while planning is pursued.
Commercial properties are often ineligible for standard commercial mortgages due to vacant possession, short leases, or mixed use. Bridging provides funding while the situation is stabilised.
Property-owning businesses use bridging loans to release equity for working capital, VAT liabilities, or time-sensitive business opportunities — faster than a remortgage and without the long-term commitment.
