About HouseCheckup
HouseCheckup is the UK's first composite property intelligence platform. We combine 12 official government data sources into a single HouseCheckup Score (0-100) that tells you everything you need to know about any UK property -- before you buy, sell, or invest.
Think of it as CARFAX for property. Just as you would check a car's history before buying it, you should check a property's full data picture before committing to the biggest purchase of your life.
Our mission
The UK property market is opaque. Buyers spend weeks gathering information from dozens of different sources. We believe every buyer deserves to make informed decisions with complete, transparent data.
Transparency first
We only use public government data. Our scoring methodology is published openly. No black boxes.
Data integrity
We never fabricate or extrapolate data. If a data point is unavailable, we say so clearly.
Accessibility
Property data should not be gatekept. Basic information is free for everyone, always.
Our data sources
We source data exclusively from official UK government open data published under the Open Government Licence (OGL v3). No third-party data brokers. No scraped content.

Scoring methodology
The HouseCheckup Score is a weighted composite of 12 data factors. Each factor is individually scored 0-100, then weighted to produce the final score. Here is how the weights are distributed.
| Factor | Weight | Data Points |
|---|---|---|
| Flood Risk | 15% | EA flood zone, surface water, reservoir risk |
| EPC Rating | 12% | Energy efficiency band and estimated costs |
| Crime | 12% | Postcode-level crime rates vs national average |
| Schools | 12% | Distance-weighted Ofsted ratings within 1 mile |
| Price Trend | 10% | 5-year price performance vs local average |
| Transport | 8% | Distance to nearest station, bus stops |
| Broadband | 6% | Average download speed and ultrafast availability |
| Air Quality | 6% | NO2 and PM2.5 concentration levels |
| Planning | 5% | Nearby planning applications in last 12 months |
| Lease Health | 5% | Remaining lease years (leasehold only) |
| Heritage | 5% | Listed building proximity, conservation area |
| Subsidence | 4% | BGS shrink-swell clay risk |
Weights are subject to periodic review based on user feedback and data quality. Last updated: March 2026.
