Know My Postcode does not invent numbers. Every figure in a report or area guide is taken from an official or open source, listed below, and shown with its date wherever we can. Reports are built live in your browser from these sources when you search, so they are as current as the source itself.
We are an independent site, not affiliated with any of these bodies. Where a source does not cover a place, we say so on the page instead of showing a guess.
| Topic | Source | Coverage | Updated | What to know |
|---|---|---|---|---|
| Crime | Police.uk street-level crime (data.police.uk) | England, Wales and Northern Ireland. Not Scotland, and not Greater Manchester Police, which does not publish street-level data. | Monthly, about two months behind | We show the last six months within roughly 1 mile of the postcode, by crime type. Police.uk moves some crimes to the nearest "anonymous" point, so streets are approximate. |
| Sold prices | HM Land Registry Price Paid Data | England and Wales | Monthly | We show the median, not the mean, because single large sales skew averages. If a postcode has fewer than three sales we widen to the postcode sector and say so. |
| Price trends | UK House Price Index (HM Land Registry, ONS, Registers of Scotland) | UK, by local authority | Monthly, about two months behind | Local authority averages, not street level. Figures on area guides are the latest month published. |
| Private rents | ONS Price Index of Private Rents | England and Wales by local authority; Scotland by rental market area; region where no local figure exists | Monthly | Northern Ireland has no area-level figures. Rents are averages for the whole council area. |
| Council tax | DLUHC Council Tax levels set by local authorities, 2026-27 (Table 10) | England only | Annual | Average Band D including parish, police and fire precepts. Wales, Scotland and Northern Ireland are not yet included. |
| Broadband | Ofcom Connected Nations, January 2026 fixed broadband coverage | UK, by postcode | Roughly twice a year | Availability (the share of premises that can order 30 Mbit/s, 100 Mbit/s, 300 Mbit/s and gigabit), not the speed a given household receives. |
| Mobile coverage | Ofcom Connected Nations, January 2026 mobile coverage | UK, by local authority | Roughly twice a year | Published by Ofcom only at council level, so every postcode in a council shows the same figure. |
| Flood risk | Environment Agency flood risk zones and surface water | England only | Rolling | Wales (NRW), Scotland (SEPA) and Northern Ireland (DfI) are not yet included. A failed lookup shows as unknown, never as low risk. |
| Noise | DEFRA strategic noise mapping, round 3 (road and rail Lden) | England only, major roads and railways in agglomerations | Every five years | Modelled values. Absence of a modelled band does not mean a place is quiet. |
| Planning applications | PlanIt (planit.org.uk), which collates council planning registers | England, Wales and Scotland | Daily | Medium and large applications within 1 km in the last two years. Coverage depends on each council publishing its register. |
| Schools | Ofsted inspection outcomes and Department for Education data | England | As published | Latest published Ofsted judgement. Some schools have not been inspected recently. |
| Deprivation | English Indices of Deprivation 2025 (MHCLG) | England only | Every few years | Relative ranking of small areas (LSOAs), not an absolute measure. Welsh, Scottish and Northern Irish indices are not yet included. |
| Postcodes and boundaries | postcodes.io, built on ONS and Ordnance Survey open data | UK | Regularly | Used to find the council, ward, region and coordinates for a postcode. |
