FAQ
Data & sources — common questions
- What data sources does PropXpert use?
- PropXpert is built on public UK datasets: HM Land Registry Price Paid (sold prices), Energy Performance of Buildings Certificates, ONS Census 2021 and small-area income, ONS/OS postcode and address products, Police.uk crime, Ofcom broadband, Defra air quality, DfE schools and Ofsted, and the Environment Agency Flood Map for Planning. Each is listed above with its coverage.
- How current is the data?
- Datasets refresh roughly monthly, on the schedules the source bodies publish. Each area page shows the date it was last refreshed, so you can see how recent the figures are.
- Can I cite or reuse PropXpert figures?
- The underlying figures come from open data, most of it under the Open Government Licence v3.0, so you may cite the numbers with attribution to the original source (and a link back to the relevant PropXpert page is appreciated). The required attribution notices are listed above.
- Why is some data behind sign-in?
- Public area pages carry prices, EPC, transport and housing stock. Deeper layers — demographics, household income, crime, broadband, flood and air quality, plus the full per-sector reports — sit behind a free magic-link account, which helps manage bulk access to the more detailed pages.
- Does PropXpert cover the whole UK?
- No — England and Wales only. Some source datasets are published for Great Britain or the UK, but PropXpert’s area pages are scoped to England and Wales.
