UK property due diligence

What to check before
making an offer on a house

One in three UK property purchases falls through after an offer. The issues that cause this — flood risk, overpricing, short leases, planning surprises — are all in the public record. Check them in 8 minutes before you commit.

Where it fits

The UK property purchase journey

A report run at step 3 costs £39. A report run after step 5 — because the survey or searches found something — costs thousands in abortive fees.

What buyers discover too late

Six issues that change offers — or kill them

These issues appear regularly after offers are accepted and surveys commissioned. By then you've spent money, time and goodwill. All of them are checkable from official data before you offer.

Flood risk

Zone 2 or 3 flood risk adds £300–£800/yr to insurance — and some lenders won't mortgage at all.

Flood risk is one of the most commonly undisclosed material facts in UK property sales. It doesn't appear in a listing, isn't volunteered by the estate agent, and won't show up in a viewing. The Environment Agency maps every postcode in England — we pull it directly.

Sold price history

The vendor bought this property 18 months ago for £241,000. It's listed at £285,000.

Land Registry records every residential sale in England and Wales. If a vendor bought recently at a significantly lower price, you're negotiating against that data. A 3-year listing history of price reductions tells you how motivated they are. This information is public — it just isn't volunteered.

Planning applications nearby

Over 1,200 planning decisions are made every day in England. The garden view you're buying could be a building site.

Planning applications within 200 metres of a property are public record but rarely searched before an offer. An approved rear extension next door, a commercial conversion across the road, or a 40-unit development behind the garden: all of these affect value and quality of life. We pull live planning data for every report.

EPC energy rating

Moving from EPC band D to C can add ~£12,500 to a property's value (MHCLG research). A band E costs more to fix than to negotiate off.

The EPC rating affects heating bills, mortgage availability (some green mortgages require band C or above), and resale value. An estate agent may quote 'a good C rating' — the registered certificate on the EPC Register might say something different. We pull the live certificate, not the listing.

Crime rates & 12-month trend

Area crime rates can change by 30–40% in a 12-month period. A Sunday afternoon viewing tells you nothing about the trend.

Police.uk publishes monthly crime statistics at street level across England and Wales. The raw level matters — but the direction matters more. A neighbourhood with rising antisocial behaviour or burglary rates affects insurance, resale and your day-to-day experience. We show both the rate and the 12-month trend.

Leasehold & short lease

Under 80 years remaining: mortgage options narrow dramatically. Under 70 years: the cost of extending spikes. Under 60 years: some lenders refuse to lend entirely.

Leasehold status and remaining lease length can make or break a mortgage application and significantly affect resale. The Land Registry holds this information — but it's rarely included in a Rightmove listing. We surface tenure, title type and any relevant lease indicators in every report.
