Chain Break Bridging Loan UK: Buy Before You Sell

Last updated: 24 October 2026

A property chain is only as strong as its weakest link. One buyer pulling out can stall your entire move, costing you the home you have already agreed to buy. In fact, chain breaks are now the most popular reason people take out a bridging loan in the UK, ahead of auction purchases and refurbishment projects.

This guide explains how a chain break bridging loan works, what it costs, who qualifies and how to reclaim the stamp duty surcharge once your old home sells. If you are stuck in a broken chain and need to move quickly, this is the route that keeps your purchase alive.

What Is a Chain Break Bridging Loan?

A chain break bridging loan is a short-term secured loan that lets you complete on a new property before your current home has sold. It bridges the gap between buying your next home and receiving the proceeds from your existing one, so you do not lose the property you want because your chain has collapsed.

Why property chains break

Chains collapse for all sorts of reasons. A buyer further down the line may fail their mortgage application. A survey might reveal unexpected problems that make someone withdraw. Gazumping, divorce, job relocations and changes of heart all contribute to chain failures. According to industry data, roughly one in three property transactions in England and Wales falls through before completion.

How a bridging loan solves the problem

Rather than waiting for a new buyer and risking your seller walking away, a bridging loan gives you the funds to complete immediately. You effectively become a chain-free buyer, which makes your offer far more attractive to the vendor. Once your old home sells, you use the proceeds to repay the bridge. The whole process can complete in as little as one to three weeks, compared to three or four months for a standard mortgage.

Because the loan is secured against property (either your existing home, the new one, or both) and you are buying a home to live in, this type of bridging loan is usually FCA-regulated. That means the lender must carry out full affordability checks and treat you under consumer lending rules.

How Does a Chain Break Bridging Loan Work?

A chain break bridging loan works by providing short-term finance so you can buy your new home immediately while your existing property is sold separately. The bridge is repaid in full once your old house completes, typically within three to twelve months.

Step-by-step process

Here is how the process works from start to finish:

1. Your chain breaks. Your buyer pulls out, but you have already exchanged or are close to exchanging on the home you want. You need funds quickly to avoid losing that purchase.

2. You speak to a broker. A specialist bridging broker assesses your situation, including the value of both properties, the loan amount you need and your exit strategy (how you will repay).

3. The lender issues a decision in principle (DiP). Many bridging lenders can provide a DiP within 24 hours. Some offer one on the same day.

4. Valuation and legal work begin. The lender instructs a valuation on the property being used as security. Solicitors handle the legal due diligence. Some lenders offer dual representation, where one solicitor acts for both you and the lender, to save time and cost.

5. Formal offer and drawdown. Once the valuation and legal checks are complete, the lender issues a formal offer. Funds are released to your solicitor and the purchase completes.

6. You sell your old home. With the pressure off, you can market your existing property properly and wait for a genuine buyer at the right price.

7. You repay the bridge. When your old home sells, the sale proceeds clear the bridging loan in full, including any rolled-up interest and fees.

What happens to your existing mortgage?

If you still have a mortgage on your current home, the bridging lender will usually take a second charge behind it. Alternatively, some structures involve paying off your existing mortgage with the bridge and placing a first charge on the old property. Your broker will advise on the best approach for your circumstances. In practice, the lender needs to see enough equity across both properties to support the loan.

How Much Does a Chain Break Bridging Loan Cost?

A chain break bridging loan typically costs between 0.5% and 1.5% per month in interest, plus arrangement fees of 1% to 2% of the loan amount. The total cost depends on your loan-to-value ratio, credit profile, the property and how long you hold the bridge.

Interest rates by LTV

Bridging loan rates vary significantly depending on how much you borrow against the property value. Here is what you can expect in the current market:

LTV band	Monthly rate	Annualised equivalent
Up to 50%	0.44% to 0.83%	5.3% to 10.0%
50% to 60%	0.83% to 0.95%	10.0% to 11.4%
60% to 70%	0.95% to 1.05%	11.4% to 12.6%
70% to 75%	1.05% to 1.25%	12.6% to 15.0%
75% to 80%	1.25% to 1.50%	15.0% to 18.0%

Other fees to budget for

Interest is not the only cost. You should also expect:

Arrangement fee: Usually 1% to 2% of the loan amount. On a £200,000 bridge, that is £2,000 to £4,000. This can often be added to the loan so you do not need to pay it upfront, but it will then attract interest.

Valuation fee: Typically £500 to £1,500 depending on the property value. Some lenders accept automated or desktop valuations for straightforward residential properties, which are cheaper and faster.

Legal fees: You will need a solicitor, and the lender will need one too. Dual representation, where one firm acts for both sides, typically costs £1,000 to £2,000. Separate representation will cost more.

Exit fee: Some lenders charge a fee when you repay the loan. However, many specialist bridging lenders do not charge exit fees at all. Always check before you commit.

Broker fee: If you use a broker (which is recommended for bridging), they may charge a fee of 0.5% to 1% of the loan, or a fixed fee.

Worked example: cost of a six-month chain break bridge

Suppose you need a £200,000 bridging loan at 60% LTV with a monthly rate of 0.95%:

Cost	Amount
Interest (0.95% x 6 months)	£11,400
Arrangement fee (1.5%)	£3,000
Valuation fee	£750
Legal fees (dual rep)	£1,500
Total cost of bridging	£16,650

That works out at roughly £2,775 per month. It sounds expensive, but consider the alternative: losing the property you want, paying to restart your search, and potentially facing higher prices or mortgage rates later.

Three ways to handle interest

Bridging lenders offer three options for paying interest:

Monthly (serviced): You pay interest each month, like a standard mortgage. This keeps the balance from growing but requires proof of affordability.

Retained: The lender deducts the full interest for the agreed term upfront and holds it. You receive a smaller net advance but make no monthly payments. If you repay early, unused interest is refunded.

Rolled up: Interest is added to the loan balance each month and paid in full when you exit. This means no monthly payments, but the total amount you owe grows over time. For example, £200,000 at 0.95% rolled up for six months becomes £211,400 at redemption.

What LTV Can You Get on a Chain Break Bridge?

Most bridging lenders offer up to 75% loan-to-value on a chain break bridge, with some specialist lenders going up to 80%. If you can offer additional security, such as a second property, some lenders will consider up to 100% of the purchase price.

How LTV is calculated

LTV on a bridging loan works slightly differently from a standard mortgage. The lender looks at the gross loan amount (including any retained interest and fees added to the loan) as a percentage of the property value. Therefore, if you add your arrangement fee and interest to the loan, the effective LTV will be higher than the initial advance alone.

For instance, a £200,000 bridge on a £300,000 property is 66.7% LTV. But if you add a £3,000 arrangement fee and £11,400 retained interest, your gross loan is £214,400, which pushes the LTV to 71.5%. This matters because it moves you into a higher rate band.

Using equity across both properties

In a chain break scenario, you typically have significant equity in your existing home. Lenders consider this when assessing your application. Some will take a charge on both properties to provide a higher loan amount against the new purchase. For example, if your old home is worth £400,000 with a £100,000 mortgage remaining, you have £300,000 of equity as additional security. That combined position makes you a much stronger applicant than your new purchase LTV alone suggests.

Do You Pay Stamp Duty on a Chain Break Purchase?

Yes, you will pay stamp duty on your new purchase, and because you will temporarily own two properties, you will also pay the 5% additional property surcharge on top of the standard SDLT rates. However, you can reclaim this surcharge from HMRC once your old home sells, as long as it completes within 36 months.

How the 5% surcharge works

Since 31 October 2024, anyone buying an additional residential property in England or Northern Ireland pays a 5% surcharge on top of the standard SDLT rates. When you use a bridging loan to buy before you sell, you temporarily own two homes, which triggers this surcharge at completion.

The standard SDLT rates from 1 April 2025 are:

Purchase price band	Standard rate	With 5% surcharge
£0 to £125,000	0%	5%
£125,001 to £250,000	2%	7%
£250,001 to £925,000	5%	10%
£925,001 to £1,500,000	10%	15%
Over £1,500,000	12%	17%

Worked example: SDLT on a £350,000 chain break purchase

Band	Standard SDLT	With 5% surcharge
£0 to £125,000 (0% / 5%)	£0	£6,250
£125,001 to £250,000 (2% / 7%)	£2,500	£8,750
£250,001 to £350,000 (5% / 10%)	£5,000	£10,000
Total	£7,500	£25,000
Surcharge amount (reclaimable)		£17,500

You would pay £25,000 in SDLT at completion. Once your old home sells within 36 months, you can claim back the £17,500 surcharge from HMRC.

How to reclaim the surcharge

The refund is not automatic. You must submit a claim to HMRC after your old property sells. The deadline is the later of:

• 12 months after the sale of your previous main residence, or
• 12 months after the filing date of the SDLT return for your new property (which is normally 14 days after completion)

In practice, most people claim immediately after their old home sells. Your solicitor or accountant can handle the paperwork. The key point is that you must sell your previous main residence within 36 months of buying the new one to qualify for the refund.

Open vs Closed Bridging Loan: Which Do You Need?

A closed bridging loan has a fixed repayment date, usually because you have exchanged contracts on your sale and know exactly when the money is coming. An open bridge has no set repayment date, giving you more flexibility but typically costing slightly more in interest.

When a closed bridge makes sense

If you have already exchanged on your old property and the completion dates do not align, a closed bridge fills the gap. Because the lender knows exactly when repayment will happen, they can offer a lower rate. For example, your buyer has exchanged but completes four weeks after you need to complete on your new home. A closed bridge covers those four weeks at a competitive rate.

When an open bridge is the better option

In a genuine chain break, your existing home may not yet have a buyer. An open bridge gives you up to 12 months (sometimes 24) to sell without a fixed deadline hanging over you. The trade-off is a slightly higher rate and more scrutiny on your exit plan. Lenders will want to see that the property is on the market at a realistic price and that sale proceeds will comfortably clear the bridge.

Which is more common for chain breaks?

Open bridges are far more common for chain break scenarios because the whole point is that your sale has not yet completed. Closed bridges suit situations where a sale is already agreed and only the timing needs fixing. Your broker will recommend the right structure based on where your sale stands.

Who Can Get a Chain Break Bridging Loan?

Most homeowners with sufficient equity can get a chain break bridging loan, provided they have a credible exit strategy and the property is suitable security. Lenders focus primarily on three things: the property, the exit plan and the borrower’s financial position.

Eligibility criteria

Every lender has its own criteria, but broadly you will need:

Sufficient equity: Most lenders require at least 20% to 25% equity in the property used as security. If you are using your existing home, this usually means an LTV of 75% or below after accounting for any outstanding mortgage.

A clear exit strategy: The lender needs to see exactly how you will repay the bridge. For a chain break, this is usually the sale of your existing home. Having the property already on the market with an estate agent strengthens your application considerably.

Proof of income: If you are paying interest monthly (serviced), you will need to demonstrate affordability. Even with retained or rolled-up interest, regulated bridging lenders must assess your ability to manage the loan under consumer lending rules.

Acceptable credit history: A clean credit record helps, but it is not always essential. Some specialist lenders consider applicants with adverse credit if the security is strong and the exit plan is solid. However, expect a higher rate.

Identity and source of funds: Standard anti-money-laundering checks apply. You will need to provide ID, proof of address, and evidence of where your deposit and equity come from.

Who bridging lenders will not usually help

Applicants without a realistic exit plan will struggle. If your property is unsaleable (for example, due to structural issues or planning restrictions) or your equity is too thin, most lenders will decline. Similarly, if you cannot demonstrate any income and the loan is regulated, affordability rules may prevent approval.

How Quickly Can You Complete a Chain Break Bridge?

A chain break bridging loan can complete in as little as three to seven working days for straightforward cases, though two to four weeks is more realistic for most applications. Complex cases involving leasehold titles, non-standard properties or multiple securities can take longer.

What affects the speed

Several factors determine how quickly your bridge can complete:

Valuation method: An automated or desktop valuation can be done in hours. A full physical valuation may take a week or more to arrange, especially in rural areas.

Legal complexity: If the property has a clean freehold title with no complications, legal work can be completed quickly. Leasehold properties, shared freeholds, or titles with restrictions will take longer.

Solicitor availability: Dual representation (one solicitor for both you and the lender) is faster than separate representation. Make sure your solicitor has bridging experience, as some high street firms are not set up for the speed required.

Loan size: According to specialist lender Finbri, loans up to £300,000 can complete in around three days, loans up to £700,000 in about seven days, and larger loans from 14 days. These are best-case scenarios, but they illustrate the speed advantage over a standard mortgage.

How to speed things up

Prepare your documents before you apply. Have your ID, proof of address, income evidence, existing mortgage statement and property details ready. Instruct a bridging-experienced solicitor early. Choose a lender that offers desktop valuations where possible. The more prepared you are, the faster the process moves.

What Are the Risks of Bridging to Break a Chain?

The main risks of a chain break bridging loan are the high cost of borrowing, the possibility that your existing home takes longer to sell than expected, and the fact that your property is at risk if you cannot repay. These risks are manageable with proper planning, but you need to go in with your eyes open.

Cost risk

Bridging finance is significantly more expensive than a standard mortgage. At 0.95% per month on a £200,000 loan, you are paying £1,900 in interest every month. If your property takes six months to sell instead of three, that is an extra £5,700 in interest alone. On the other hand, fees you have already paid (arrangement fee, legal, valuation) are sunk costs whether the bridge lasts one month or twelve.

Property market risk

If the market softens while you hold the bridge, your old home may sell for less than you expected. This could eat into your equity and leave you with less to put toward your new mortgage. In extreme cases, it could mean the sale proceeds do not fully clear the bridge. Therefore, it is sensible to price your old home realistically from the start rather than holding out for top price.

Repayment risk

Your property is used as security. If you cannot repay the bridge within the agreed term and the lender cannot extend, they have the right to take possession and sell the property to recover their money. This is the most serious risk, and it is why your exit strategy must be realistic.

How to manage the risks

Price your existing property competitively from day one. Build a contingency buffer into your costs by assuming the bridge will last longer than you hope. Discuss with your broker whether a 12-month term gives you enough headroom, even if you expect to sell in three to six months. Consider whether retained interest (paid upfront) gives you more certainty than rolled-up interest. Above all, make sure the numbers work even in a slow market.
