Know what you're walking into.
Agents and sellers know things about a property that buyers don't easily find. Enter a postcode and get a briefing before the viewing: what nearby homes actually sold for, recorded crime, live flood warnings, whether the ground was mined, what's listed next door, and which questions those findings should make you ask.
Free, no account. Built on HM Land Registry, data.police.uk, the Environment Agency, the Mining Remediation Authority, Historic England and the Department for Education.
What this is and isn't
The Postcode Brief is an informational aid assembled from UK government open data. Every briefing describes the area around a postcode, not one identified address: a postcode typically covers around fifteen homes, so treat all of this as the ground a house stands on rather than a report on the house itself. It is not a substitute for a solicitor's searches, a survey, a mortgage valuation, or the official long-term flood risk checker, and it cannot tell you whether a home is in a school's catchment. Data is only as current as its publisher: sold prices lag completion by weeks, crime figures by a month or two, and certificates by years. Use it to know what to ask, not as the answer.
