About the data

Everything on this site is built from official government statistics. This page says exactly which ones, what we do to them, and where their limits are.

Who runs this site

EPC Register Check is an independent site. It is not the official EPC register, and it has no connection to the government. The official register, where you can look up the certificate for any individual address free of charge, is at gov.uk/find-energy-certificate.

Source

Our local authority statistics come from the live tables on Energy Performance of Buildings Certificates published by the Ministry of Housing, Communities and Local Government. We use Table D1, which counts domestic certificates lodged each quarter in each local authority, split by energy efficiency band. The data is published under the Open Government Licence v3.0.

What we do with it

For each local authority we sum the quarterly band counts into two views: all certificates since the series began in 2008, and the last 4 quarters. From those we calculate the share rated C or better, rank the 320 local authorities, and derive average floor area per certificate. The processing is a single documented script; we add nothing to the numbers and model nothing.

Update cadence

MHCLG updates the live tables quarterly. The data on this site currently runs to Q2 2026 and was last retrieved and checked on 2026-09-06. Each page shows this same provenance line at the bottom.

What the numbers can and cannot tell you

The statistics count certificates lodged, so they describe homes at the moment they were built, sold or let. Three consequences follow. First, recent figures lean towards new builds and homes that recently changed hands, which rate better than the housing stock as a whole. Second, one home can appear more than once across the years if it was assessed more than once. Third, quarterly lodgement counts track market activity as much as anything about the housing itself.

Treat area comparisons as a picture of what has been certificated, and be careful reading them as a picture of every home in the area.

What is coming

We are building towards postcode-level pages combining EPC data with other open datasets, including flood risk from the Environment Agency and radon potential from the British Geological Survey and UK Health Security Agency, each carrying its own attribution and caveats.
