Data

Our Methodology

Where our data comes from and how we process it.

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

data.police.uk

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.

Demographics

ONS Census 2021

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.

Broadband

Ofcom Connected Nations

Broadband speed and coverage statistics are sourced from Ofcom's Connected Nations dataset, which covers average download speeds, superfast (>30 Mbps), ultrafast, and full fibre (FTTP) coverage by postcode area.

Council Tax

Valuation Office Agency (VOA)

Council tax band distributions (the proportion of properties in each band A–H) are sourced from the VOA's council tax stock of properties data. Band D rates are sourced from local authority data.

Energy Efficiency

MHCLG Open EPC Register

Energy Performance Certificate (EPC) ratings are sourced from the open EPC register published by the Ministry of Housing, Communities & Local Government. We calculate the average EPC score and distribution of ratings (A–G) per postcode district.
