A property chain is only as strong as its weakest link. A buyer who has found the right home but whose own sale has stalled, or a seller whose buyer has pulled out, can lose the purchase altogether. Bridging finance is one of the tools used to break a chain: it provides short-term funds so that a purchase can complete without waiting for the existing property to sell. It is a specialist, relatively expensive form of borrowing, so it is worth understanding how it works and when it makes sense before relying on it.
How a chain-breaking bridge works
The borrower takes a short-term loan, secured by a charge over the property, that covers the cost of the new purchase (or the shortfall) while the existing home is still on the market. Once the old property sells, the proceeds repay the bridge, usually including any rolled-up or retained interest. The loan term is typically measured in months, commonly up to 12 and sometimes longer, depending on the lender and the case.
Lenders can often move much faster than a standard mortgage lender because the decision rests mainly on the value of the security and the credibility of the exit, rather than a full income and affordability assessment. That speed is the main reason bridging is used where a completion date is fixed and cannot be moved.
Open and closed bridging
- Closed bridge. The exit is certain and evidenced, for example where contracts have already been exchanged on the sale of the existing home but completion falls after the purchase. Lenders view this as lower risk and will usually price it more keenly.
- Open bridge. The existing property has not yet sold or exchanged. There is no fixed repayment date, so lenders take a more cautious view of the loan-to-value, the asking price and how realistic it is that the property will sell within the term.
What it costs
Bridging is typically priced as a monthly interest rate rather than an annual percentage, alongside arrangement fees, valuation costs, legal fees for both sides and sometimes an exit fee. With the Bank of England Bank Rate at 3.75% following the September 2026 decision to hold, pricing varies significantly with loan-to-value, property type and the strength of the exit. Interest is often rolled up or retained from the advance, which reduces the net amount released. The total cost over the expected term, not just the headline monthly rate, is what should be compared against the alternative of losing the purchase or accepting a lower price from a quick buyer.
Planning the exit
The most important question is how the loan will be repaid. If the existing home does not sell in the time expected, the borrower may need to extend, reduce the price or refinance, each of which adds cost and risk. Lenders will want to see a realistic valuation, a sensible asking price and evidence of agent activity. Our guide to bridging loan exit strategies and what lenders need to see explains how exits are assessed and what happens if the plan changes.
It also helps to understand how long a conventional purchase takes when comparing options; our mortgage timeline from agreement in principle to completion shows where the delays that break chains usually arise.
Alternatives to consider first
A bridge is not always necessary. Possible alternatives include asking the seller for a longer completion window, agreeing a delayed completion with the buyer, renting for a short period after selling, or negotiating a price adjustment with a more flexible buyer. Where those options are not realistic, bridging may be the practical route, but borrowers should be clear that they are taking on secured short-term debt with a repayment date.
Regulated and unregulated bridging
Whether a bridging loan is regulated depends on how the property is used. A bridge secured on a home the borrower or a close family member lives in, or intends to live in, can be a regulated mortgage contract, with the protections that follow. Bridging secured on an investment property is generally unregulated. The correct classification affects the rules the lender must follow, so it should be established at the start.

Our bridging finance service page sets out how we structure short-term funding, and the Bridging and Development Finance Hub collects related guides on exits, refurbishment and development.

YOUR HOME MAY BE REPOSSESSED IF YOU DO NOT KEEP UP REPAYMENTS ON YOUR MORTGAGE OR ANY LOAN SECURED AGAINST IT. Bridging finance secured on investment or commercial property is generally unregulated by the FCA. Your property may be sold if the loan is not repaid or refinanced within the agreed term.
