HouseCheckup scans 70+ official data sources to flag potential red flags for any UK property. Unlike HomeThink's AI analysis of listing photos, HouseCheckup checks hard data: flood zones, ground instability, radon, contaminated land, coal mining, sewage overflows, noise, air quality, and planning constraints. Enter any address to see a free red flags summary — the £14.99 Complete report includes full risk assessment with plain-English explanations.

This free tool checks one data point. The HouseCheckup Complete report combines 70+ data sources into an 18-page report with a composite IQ Score (0–100) — covering flood, EPC, crime, schools, transport, ground stability, investment potential, and more.
HouseCheckup checks: flood risk (all types), ground stability (shrink-swell clay, landslides, collapsible ground), radon gas levels, contaminated land, coal mining activity, sewage overflow proximity, noise and air pollution, coastal erosion, planning constraints (conservation areas, listed buildings, TPOs), and more. Each risk is assessed using official government data.
HouseCheckup checks data-based risks that a surveyor can't see by walking through the property — underground hazards, environmental risks, and area-level issues. A physical survey checks the building structure, damp, roof condition, etc. The two are complementary: use HouseCheckup for data-based risks, and a surveyor for physical inspection.
HouseCheckup is not a substitute for lender-required conveyancing searches (local authority, water, environmental, chancel — typically £250–450). It's a faster, cheaper first step to help you decide if a property is worth pursuing before committing to expensive legal searches. Think of it as due diligence before the due diligence.
