Why ClozeSure exists
Our founder Peter’s sister experienced this first-hand — her buyer pulled out after exchange, and she was unable to move on, along with the stress, uncertainty and serious costs she endured.
That’s when the idea for ClozeSure was born.
Our team
Peter assembled a team of financial, property and IT experts to create and build a solution that simply didn’t exist: a straightforward guarantee that means your property sale completes, in time, no matter what.
Our solution
If your buyer fails to complete after exchange, ClozeSure steps in, as your safety buyer, and buys your property instead — ensuring you receive your full agreed price. Your sale completes. Your chain holds. Your plans stay intact.
From £60, paid on completion.

WHY BUYERS FAIL TO COMPLETE
It happens more than you think
After exchange, buyers do still fail to complete — and you carry the consequences. Our research shows this happens hundreds of times a year across England and Wales.
Chains break
Your buyer's own sale falls through, leaving them without the funds to complete yours. One weak link unravels everything.
Mortgage withdrawn
A lender pulls an offer after exchange — due to a change in the buyer's circumstances, a tightened credit assessment or other delays.
Personal crisis
Serious illness, bereavement, separation or accident can force a buyer to abandon their purchase — through no fault of yours.
Legal difficulties
Criminal charges, fraud investigations, financial injunctions or failure of legal representation can make it impossible for a buyer to complete.
Job loss
Redundancy, relocation, a withdrawn job offer or a major change in employment removes the financial basis for the purchase.
Market shift
A sudden drop in property values or a rise in borrowing costs can prompt a buyer to forfeit their deposit rather than complete at a price that no longer feels right.
ClozeSure protects you against every one of these scenarios.

Your sale matters — whatever the reason
ClozeSure is for any residential seller who needs certainty. Here are the people we protect most.
~67% of UK sales
In a property chain
Your sale is only as strong as its weakest link. One failed buyer can unravel months of planning, costs, and onward purchases.
Nearly half of all sellers
Downsizing
The timing has to be right. ClozeSure makes sure your sale completes, so your plans stay on track — not held hostage to someone else's circumstances.
~10% of UK sales
Probate sale
You're selling on behalf of an estate and representing beneficiaries. Uncertainty is the last thing any of you need. ClozeSure gives you a guaranteed outcome.
Life event
Your life circumstances change prompting you to sell your home. You need peace of mind and certainty. The last thing you need is the sale itself falling apart. We make sure it doesn't.
WHAT WE ARE
We're not insurance. We're not a loan.
We are a legally binding property contract, enforceable only by you, the seller, that gives you certainty from the moment you exchange.
Not insurance Insurance pays a claim after a loss. ClozeSure prevents the loss — your sale completes regardless.
Not a loan No debt. No repayment. No interest. You receive your full agreed sale price — nothing borrowed, nothing owed.
Not a quick-buy service iBuyers typically offer 15–25% below your agreed sale price. ClozeSure completes at the full agreed amount — we purchase at 90% and you keep the buyer's 10% deposit, so you receive exactly what you were expecting.
Frequently Asked Questions
Yes. You are not obliged to trigger ClozeSure. You can decide to keep your property, or put it back on the market.
If you wish to trigger the guarantee, you should immediately advise ClozeSure, who will start the acquisition process.
Your buyer will be given (via the conveyancers) a Completion Notice, giving the buyer ten days to complete the purchase. If the buyer fails to complete, your sale will be deemed to have failed and your defaulting buyer will forfeit their 10% deposit. If you wish to trigger ClozeSure, we will purchase the property and pay 90% of the original sale price.
We’ve designed our system to be fast, efficient, and helpful, with an aim of completing our purchase of your property immediately after - on the same day - as your defaulting buyer fails to complete.
To make sure we meet this goal, we need to work closely with you and your conveyancer.
By working closely together, we can make sure that your onward purchase — if you are planning one — completes successfully and secures the property chain.
On completion, your conveyancer will deduct their fees, pay any estate agent’s fees, redeem any mortgage on the property (if you have one) and then send you the remaining proceeds of sale.
The same amount you would have received if your original buyer had completed their purchase.
As soon as ClozeSure’s conveyancing requirements have been concluded, payment is made to your conveyancer for 90% of the original sale price. Our aim is for this to take place ten days after your original completion date. When your conveyancer receives the money from ClozeSure, they will deduct their fees, pay any estate agent’s fees, redeem any mortgage on the property (if you have one) and then send you the remaining proceeds of sale.
Yes, you will receive a full refund of your fee.
ClozeSure will start on the day you exchange contracts for the sale of your property and confirm receipt of the 10% deposit paid by your buyer. Your conveyancer will need to confirm both exchange of contracts and receipt of the 10% deposit.
If your sale collapses prior to exchange of contracts, you will be entitled to a full refund of your fee.
Yes, up to 2 business days after exchange of contracts.
You are only eligible to apply for the ClozeSure Guarantee before, or on, or within 2 business days after, the day of exchange of contracts.
