Should I Buy This House? Get a Free 0–100 HouseCheckup Score

Before you offer on a property, run its postcode through the free HouseCheckup Score. We combine flood risk (Environment Agency), coal mining (Mining Remediation Authority), radon (UKHSA), subsidence (British Geological Survey) and crime (police.uk) into one 0–100 number — framed over a typical 30-year mortgage. The score and every metric behind it are free to see, with no sign-up. The £24.99 Complete report then goes deeper on your exact address with the full 30-year projection, EPC band and fix-list.

Free instant result from official UK government data. No sign-up to see your score.

How the HouseCheckup Score works

The HouseCheckup Score turns five separate official-data checks into a single 0–100 number for a postcode, so you can sanity-check a property in seconds before booking a viewing or making an offer. Higher is better. Every component is scored independently, weighted by how much it tends to matter to buyers and lenders, and combined into the headline figure. Crucially, the score and the finding behind every metric are free to see — there is no blurred preview and no sign-up to read your result.

The five free checks are:

  • Flood risk — Environment Agency flood-warning areas near the postcode.
  • Coal mining — the Mining Remediation Authority's Development High/Low Risk Area screen.
  • Radon — the UKHSA / BGS Indicative Atlas of Radon potential band.
  • Subsidence — the British Geological Survey clay-shrinkage (shrink-swell) climate trajectory.
  • Crime — police.uk street-level crime in the latest published month.

What the score does — and does not — tell you

The score is a first filter, not a verdict. It is built from area-level and point-level government data that a surveyor cannot see by walking through a property: underground and environmental risks, plus neighbourhood crime. It does not replace a structural survey, a Coal Mining Risk Assessment where one is flagged, or the legal searches your conveyancer will run. Used well, it tells you which properties are worth the cost of that deeper due diligence — and which carry risks you'd want priced into your offer.

Why EPC is in the report, not the free score

Energy performance matters to running costs and value, but live EPC lookup is gated behind an operator data token. Rather than show a guessed or broken value, we degrade gracefully and point you to the authoritative free source: the government register at gov.uk/find-energy-certificate. Full EPC detail is built into the £24.99 Complete report, alongside the five checks above plus 70+ further data sources.

Going deeper on your exact address

The free score works at postcode level. When you've shortlisted a property, the Complete report goes deeper on the specific address: the full 30-year flood projection and Flood Re eligibility, the EPC band, a coal-mining risk assessment where relevant, and a plain-English fix-list. It's a one-off purchase — £9.99 Lite or £24.99 Complete, no subscription and no auto-renew — not a recurring plan. Explore related single-hazard checks too: flood risk, ground stability and radon.

Frequently asked questions

The HouseCheckup Score is a composite 0–100 rating (higher is better) that combines five official-data checks for a postcode: flood risk from the Environment Agency, coal mining risk from the Mining Remediation Authority, radon potential from UKHSA, clay-shrinkage subsidence from the British Geological Survey, and street-level crime from police.uk. Each component is scored, weighted, and combined — and shown to you free, with the named government source on every number. EPC is added in the full report.
Yes. Enter any UK postcode and the score, the band, and the one-line finding for each of the five checks render instantly with no sign-up and no card. You only pay if you want the full report for a specific address — a one-off £9.99 Lite or £24.99 Complete, with no subscription and no auto-renew.
No. The HouseCheckup Score is a fast, data-driven first filter to help you decide whether a property is worth pursuing before you commit to expensive surveys and conveyancing searches. It uses only official government data, but it is not a substitute for a structural survey, a Coal Mining Risk Assessment where flagged, or your solicitor's legal searches. Think of it as due diligence before the due diligence.
Live EPC lookup is gated behind an operator data token, so we degrade gracefully rather than show a broken or guessed value. You can look up any property's EPC for free right now on the official government register at gov.uk/find-energy-certificate, and the full EPC detail is built into the HouseCheckup Complete report alongside the other checks.
