Nearly two-thirds of UK homeowners under 35 say they regret something about their purchase, with underestimating costs being the most common complaint. That figure — 63% of 18–34-year-olds — tells me something important. Most first-time buyers focus entirely on the deposit and the monthly mortgage payment, and they miss the smaller costs that pile up fast. I’ve watched this pattern repeat for years, and it’s why I want to talk about one specific protection that rarely gets mentioned: down payment insurance when buying an apartment.
Here’s the thing. When you put down a 5% deposit on a £300,000 apartment — that’s £15,000 — you have very little room for error. If the sale falls through because of a survey issue, a chain collapse, or a problem with the leasehold, you could lose that money. Down payment insurance, sometimes called home buyer protection insurance, covers that exact scenario. It’s a small upfront cost that protects your biggest single outlay before completion. Here’s what you actually need to know.
What Down Payment Insurance Actually Covers
Most people assume their deposit is safe in a solicitor’s client account. It usually is — until something goes wrong and the seller pulls out, or a survey reveals a structural problem that makes the apartment unmortgageable. In those situations, you don’t automatically get your survey fees or legal costs back. Down payment insurance fills that gap.
What I’d do is look for a policy that covers at least three things: the deposit itself, the survey costs, and the legal fees. Some policies also cover mortgage arrangement fees, which can run up to £1,500. On a typical purchase, those combined costs could easily reach £3,000 to £5,000. A policy costing £74 to £150 looks very different when you think about it that way. If you’re buying an apartment with a leasehold, you might also want to check whether the policy covers issues discovered in the leasehold documents — that’s a common reason deals fall through.
Why This Matters More for Apartment Buyers
Apartments come with extra layers of complexity that houses don’t. Leasehold terms, service charges, ground rent, and building insurance requirements can all throw up surprises late in the process. A survey might reveal that the building has cladding issues, or that the service charge is about to double. In those cases, your lender may refuse to lend, and you’re left with no property and a pile of bills.
Our HomeOwners Survey 2025 found that more than a third of all UK homeowners regret aspects of their purchase. For apartment buyers, the risks are even higher because of the shared ownership structure. If the freeholder decides to increase the ground rent or impose major works, your mortgage offer could be withdrawn at the last minute. Down payment insurance covers that exact scenario.
I’ve seen buyers lose their entire deposit because they didn’t realise the leasehold had only 70 years remaining, which made the property unmortgageable. A good survey would have caught it, but the survey fee was already spent. Down payment insurance would have covered both the survey cost and the deposit. That’s the kind of protection that turns a disaster into an inconvenience.
Where People Go Wrong With Down Payment Insurance
The most common mistake is not buying it at all. Buyers assume the process will go smoothly, or they think their solicitor will protect them. But solicitors can’t insure against a seller changing their mind or a survey revealing a fatal flaw. The second mistake is buying the cheapest policy without reading the exclusions. Some policies won’t cover you if you pull out because of a change in your personal circumstances, like losing your job. Others exclude chain-related collapses.

| Cost Type | Typical Amount | Covered by Insurance? |
|---|---|---|
| Deposit (5% on £300k) | £15,000 | Yes — main purpose |
| Survey fee | £300–£1,500 | Yes — most policies |
| Solicitor fees | £800–£1,800 | Yes — most policies |
| Mortgage arrangement fee | £0–£1,500 | Sometimes — check terms |
Buying too late in the process
Some buyers wait until they’ve had an offer accepted before looking for insurance. By then, the survey might already be booked, and the policy won’t cover pre-existing issues. Buy the insurance the day your offer is accepted, before you spend any money on surveys or legal fees.
Assuming the seller’s insurance covers you
The seller might have buildings insurance, but that protects their property, not your deposit. Your deposit is only protected if you have your own policy. There’s no overlap.
Not checking the cooling-off period
Most policies have a 14-day cooling-off period. If you find a better deal or change your mind, you can cancel within that window. After that, you’re locked in. Read the terms before you pay.

Compare policies on coverage, not just price
The cheapest policy might only cover the deposit, leaving you to absorb survey and legal costs. A mid-range policy that covers all three — deposit, survey, and legal fees — is usually better value. Look for a policy that specifically mentions leasehold issues, chain collapses, and seller withdrawal. Those are the three most common reasons apartment purchases fall through.
Buy immediately after offer acceptance
As soon as your offer is accepted, buy the policy. Don’t wait for the survey or the mortgage offer. If you wait, you risk the survey revealing a problem that was already there, and the insurer could argue it was a pre-existing condition. The policy should be in place before you spend a penny on fees.
Keep all receipts and correspondence
If you need to make a claim, the insurer will want proof of every cost. Keep the survey invoice, the solicitor’s engagement letter, and the mortgage offer document. A home buying file organiser can help you keep everything in one place. Without receipts, the insurer may only pay the deposit and refuse the fees.
Check whether your mortgage broker offers a policy
Some mortgage brokers include down payment insurance as part of their service. If yours does, compare it to standalone policies. The broker’s policy might be more expensive, but it could be easier to claim on because the broker handles the paperwork. If you’re using a broker, ask them directly.
