UK Data Sources
Last updated: 29 April 2026
The Further Research page on every comparison links out to trusted third-party tools so you can dig deeper into an area or property without leaving the comparison. This page explains which sources we chose, why we chose them, and which sources we investigated but ultimately excluded.
Sources we use
Rightmove
The UK's largest property portal. We link to two distinct Rightmove tools: the for-sale search filtered by the property's postcode, bedroom count, and a ±25% price band; and the sold prices section, which shows Land Registry history for every sold address in the postcode.

Zoopla
One of the UK's major property portals. We link to the for-sale search filtered by postcode, bedroom count, and price band — giving you an independent view of the market alongside Rightmove.

OnTheMarket
A UK property portal with agent-exclusive listings that sometimes appear here before other portals. We link to the for-sale search pre-filtered by postcode, bedrooms, and price.

HouseMetric — Sold Prices
HouseMetric aggregates Land Registry sold prices and enriches them with floor area data, producing £ per square metre figures for individual addresses. This is the most granular comparable data available for free, making it invaluable for assessing whether an asking price is reasonable.

ScoreMyStreet — Livability
ScoreMyStreet produces a composite livability score for any UK postcode, combining schools, amenities, transport links, crime rates, and healthcare access into a single comparative view. Useful for quickly gauging whether an area meets your lifestyle requirements — especially when comparing two properties in different areas.
scoremystreet.com
GetTheData — Area Profile
GetTheData maps UK postcodes to administrative geographies: ward, local authority, parliamentary constituency, NHS Integrated Care Board, and more. It also surfaces census demographic data and open government datasets for the postcode. Useful if you need to understand boundary changes, local authority quality, or healthcare trust coverage.

GOV.UK — Energy Performance Certificates
The official government EPC register. Every domestic property sold or let in England and Wales since 2008 is legally required to have an EPC. The register lets you look up the current energy rating (A–G), the recommended rating, and whether the certificate is still valid. We link directly to a postcode search so you can pull up EPCs for any address in the postcode.

Sources we investigated but did not include
We tested every source against real postcodes before including it. The following were investigated and deliberately excluded.
Jitty
Jitty supports pre-filtered for-sale searches with postcode and price range in its URL, and the link format works correctly for well-covered urban postcodes. However, for rural or less-covered postcodes (which appear frequently in our comparisons), Jitty silently drops the postcode from the URL and returns a national price-range search — showing over 1,000 results with no location filter applied. This silent degradation is more misleading than a clear error, so we excluded it.
jitty.com
Police.uk — Crime Map
Police.uk supports postcode lookup for local crime statistics, and the link format works for some postcodes. However, we found it unreliable across different postcode districts — the same URL pattern that worked for one postcode returned a broken or empty result for another. Because we cannot guarantee a useful result, we excluded it. ScoreMyStreet incorporates crime data in its livability score as an alternative.
