Guides
PostcodeLens pulls together three official UK datasets — flood risk from the Environment Agency, recorded crime from police.uk, and sold prices from HM Land Registry — into one plain-English page for any postcode. These guides explain what that data actually means, where it comes from, and where it can mislead if you read it too quickly.
They are written for people who are about to spend a lot of money on a home: buyers researching a road before a viewing, and anyone relocating to an area they don’t know. No jargon, no spin, and honest about the limits of the numbers. For the technical detail of how we aggregate and suppress figures, see the methodology page.
How to check flood risk before buying a UK home
The free Environment Agency service, what the risk bands mean, and why a professional survey still matters.
What police.uk crime data actually means
Where the numbers come from, why small areas get suppressed, and why a raw count on its own can mislead.
How sold house-price data really works
Actual completed sales versus portal estimates, why medians beat averages, and the small-sample trap.
