All data on postcode.page is sourced from official UK government datasets published under the Open Government Licence v3.0. We process and normalise data monthly, combining multiple sources to give a complete picture of each postcode district.
House Prices
HM Land Registry Price Paid Data
We use Land Registry Price Paid data covering all residential property transactions in England and Wales. Prices are aggregated by postcode district (outcode) and broken down by property type (detached, semi-detached, terraced, flat). Year-on-year change is calculated from the same months in each year.
School Data
DfE Get Information About Schools (GIAS)
School counts and Ofsted rating distributions are sourced from the DfE GIAS register of all open schools in England. Schools are matched to postcode districts by their registered postcode.
Crime Statistics

Crime rates (per 1,000 residents) are sourced from data.police.uk, which publishes recorded crime statistics from all UK police forces. Rates are calculated using ONS population estimates for each area.

Population, age distribution, and tenure data (owner-occupied, private rent, social rent) are sourced from the 2021 England and Wales Census, published by the Office for National Statistics.
