UK property due diligence: what to check before you buy

The UK market in context

The average UK home price was £271,000 in May 2026, up 2.7% over 12 months. The averages were £292,000 in England, £215,000 in Wales and £196,000 in Scotland. Northern Ireland's latest figure was £198,000 in Q1 2026.

The national average is a benchmark, not a budget for a particular town. Property type, tenure, size and condition can move the relevant local price far away from it.

How active is the market?

HMRC recorded 98,700 seasonally adjusted UK residential completions worth at least £40,000 in June 2026. The unadjusted count was 103,050. Both figures are provisional.

Activity figures describe the whole market. For a move, the useful local questions are how many comparable homes have sold, how recently they sold and how widely their prices vary.

Broadband across the UK

In January 2026, full fibre reached 82% of UK homes and gigabit-capable broadband reached 89%. That was 24.9 million and 27.1 million homes respectively.

National coverage is high, but an address can still have different infrastructure, providers and indoor performance. Check the exact address before relying on a listing's broadband description.

The buying process changes by nation

England and Wales share the GOV.UK buying guide. Scotland has a distinct offer, missives and Home Report process, covered by mygov.scot. Northern Ireland has separate conveyancing and registration arrangements, covered by nidirect.

Use the guide for the nation where the property sits. Purchase tax, title records, searches and the point at which an offer becomes binding are not one UK-wide system.

What to check before you commit

Price and ownership

Compare completed sales of similar homes, then confirm tenure, title boundaries, rights, restrictions and any lease or management obligations.

Building and running costs

Read the survey, energy certificate and service history. Budget for repairs, insurance, council tax or rates, service charges and energy use.

Flooding and the environment

Use the official flood service for the property's nation. Check river, sea and surface-water information, then consider drainage, ground conditions, air quality and nearby land uses.

The local area

Review recorded crime, schools, transport, road safety, green space and planned development at the geography each source supports. Visit at the times you expect to travel or be at home.
