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

Before you offer on a property, run its postcode through the 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 render instantly. The £24.99 Complete report then goes deeper on your exact address with the full 30-year projection, EPC band and fix-list.

Instant result from official UK government data.

Free on-screen check. The full property report is £9.99 Lite / £24.99 Complete — one report, one price, no subscription.

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 shown in full — there is no blurred preview to read your result.

The five 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.

How EPC feeds the score

Energy performance matters to running costs and value, so when our live lookup against the official England & Wales EPC register returns a band for the postcode, that band is included as a component of the score. Where there's no match, the property sits in Scotland (a separate register), or the lookup is unavailable, the EPC component degrades to an honest gap rather than a guess — it is dropped from the weighted score rather than scored zero, and we point you to the authoritative source: the government register at gov.uk/find-energy-certificate. The full per-certificate EPC detail, with costed improvements, is built into the £24.99 Complete report, alongside the rest of its 15+ checks from official sources.

Going deeper on your exact address

The postcode 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 instantly, with the named government source on every number. EPC is added in the full report.
Enter any UK postcode and the score, the band, and the one-line finding for each of the five checks render instantly. 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.
When our live lookup against the official England & Wales EPC register returns a band for the postcode, that band is included as a component in the HouseCheckup Score. If there's no match, the property is in Scotland (a separate register), or the lookup is unavailable, the EPC component degrades to an honest gap pointing you to gov.uk/find-energy-certificate — it is dropped from the weighted score rather than guessed or scored zero, so it never drags the headline number down. The full per-certificate EPC detail, with costed improvements, is built into the HouseCheckup Complete report.
