Property Red Flags Check

HouseCheckup runs 15+ checks from official sources to flag potential red flags for any England or Wales 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 red flags summary — the £24.99 Complete report includes full risk assessment with plain-English explanations.

Frequently asked questions

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.
