Chain-breaking finance
Chain-breaking finance is a short-term bridging loan that lets you complete an onward purchase when the sale of your current home has been delayed or has fallen through. On a home you or your family will live in, it is usually a regulated loan capped at 12 months. It needs enough equity across the properties and a realistic plan to sell. We pass these enquiries to an FCA-regulated broker.

How does a chain break, and how can a bridge help?
Most UK purchases depend on a chain: your buyer needs their own sale to complete, and so on. If a buyer withdraws, a mortgage offer fails or a survey goes badly, everyone above them can be stuck. If you have already agreed — or exchanged on — your onward purchase, that can put the new home and any deposit at risk.
A bridge can, in the right case, provide independent funds so your purchase is not hostage to the broken link. You complete the new home with the bridge, then sell the old one and use the proceeds to repay. It is the same family of ideas as buy before you sell; the label here focuses on a chain that has already broken or stalled.
Is chain-breaking finance regulated?
Usually, yes. If the new home or the old one is a home you or a close family member live in or will live in, the loan is typically a regulated mortgage contract. That brings affordability checks, regulated advice, formal disclosure and normally a maximum 12-month term. BridgingLoans.online is an introducer, not an FCA-authorised broker and not a lender: we qualify purpose, occupancy and exit and pass a complete pack to an FCA-regulated broker. We do not recommend a product. If the properties are investments you will never live in, the loan may be unregulated instead — see regulated and unregulated bridging.
How is the security usually structured?
Lenders often look at both homes together: the equity in your current home and the value of the one you are buying. They may take a charge over both. The existing mortgage on your current home does not disappear unless it is repaid as part of the structure, and the lender will look at the combined borrowing against the combined value.
| Structure | How it works | Points to check |
|---|---|---|
| Charge over the new home only | Bridge secured on the purchase; old mortgage stays in place | Enough deposit and equity; paying two sets of commitments |
| Charges over both homes | Bridge secured across both; may repay the old mortgage | Combined gross LTV; consent from existing lender if second charge |
| Bridge plus a new long-term mortgage | Bridge covers the gap until the old home sells | Mortgage offer timing; affordability |
Worked example: covering a broken chain
Suppose your current home is worth £300,000 with no mortgage, the new one costs £400,000, and you need £350,000 from the lender for up to six months while you re-market the old home. Using this site’s teaching defaults and both homes as security:
| Line | Amount |
|---|---|
| Combined value of both homes | £700,000 |
| Net funds needed | £350,000 |
| Arrangement fee (2% of net, added to the loan) | £7,000 |
| Interest base (net + fee) | £357,000 |
| Monthly interest at 0.85% | £3,034.50 |
| Total interest (6 months, simple retained) | £18,207 |
| Gross facility | £375,207 |
| Net LTV | 50.0% |
| Gross LTV | 53.6% |
| Total cost of credit (fee + interest) | £25,207 |
Indicative educational example using this site’s calculator method: fee = net × 2%; interest = (net + fee) × 0.85% × months; gross = net + fee + interest. The 0.85% a month and 2% fee are teaching defaults, not our rates and not a quote. Valuation, legal and broker costs are not included.
When the old home sells, the proceeds have to repay the gross balance of £375,207. If the new home is to be held with a long-term mortgage, that mortgage must be arranged in time to take out the rest. If the sale takes longer than six months, interest continues and an extension is not automatic. The regulated broker’s illustration will show your real figures; try other terms in the calculator.
What if I have already exchanged on the onward purchase?
Once you have exchanged, you are legally committed to complete on the agreed date, and failing to do so can cost you the deposit and more. Tell your solicitor and the broker straight away, and give them the exact completion date. The regulated process still has to run, so the earlier the enquiry starts the better. If the deadline cannot be met, your solicitor can explain the options under the contract, such as negotiating a short delay with the seller. Bridging is one possible route, not a guaranteed one.
If your sale has exchanged with a new buyer and completion is just delayed, the bridge may be closed — a known repayment date. If the old home is back on the market with no buyer, it is open, and lenders will underwrite it more cautiously because the 12-month clock is real. Price the old home to sell; an optimistic asking price is not an exit. See open vs closed bridging loans.
What should I gather quickly?
- The onward purchase details: price, exchange and completion dates, deposit paid.
- Your current home: value, mortgage balance, estate agent’s appraisal and what happened to the last buyer.
- Income and outgoings, because affordability is assessed on regulated loans.
- Your solicitor’s details and the latest position in the chain.
Timescales vary and the regulated process has steps that cannot be skipped. A few weeks is more realistic than a 48-hour promise. See how fast can I get a bridging loan.
Your home or property may be repossessed if you do not keep up repayments on a mortgage or other debt secured on it.

FAQs
What is chain-breaking finance?
A short-term bridging loan that funds an onward purchase when the sale of your current home has been delayed or has fallen through. The old home’s sale then repays it.
Will I pay two mortgages and the bridge each month?
With retained interest the bridge itself may have no monthly payment. You still need a plan for any remaining first mortgage, and the regulated affordability assessment will look at your commitments.
What if I have little equity?
The combined gross LTV across the properties still has to work. Cases with thin equity are often declined.
How fast can a regulated chain-break complete?
Expect valuation, regulated advice, an illustration and consumer waiting periods. A few weeks is more realistic than a 48-hour story. Timescales vary.
What if I sell sooner than expected?
Many lenders rebate unused retained interest if you repay early, subject to a minimum interest period. Check the terms in your illustration.
