EPC Bands of dwellings in England and Wales, by property type, tenure, property age and whether new or existing.

This dataset is one of the outputs from an Ordnance Survey funded project to link Unique Property Reference Number in OS AddressBased Plus to DLUHC’s EPC data and to Land Registry’s Price Paid Data Set. The linkage to the EPC data had a 96% match rate. The linkage was designed to allow comparison with DLUHCs own linkage (93% match rate), and to allow for comparison and identification of barriers and issues to accurate matching.

Data on the energy efficiency of dwellings, environmental impact score and estimated CO2 emissions in England and Wales at the local authority district level. These are broken down by property type, tenure, age of property and whether a dwelling is new or existing.

As of the 1st quarter of 2024, most non-residential buildings with an energy performance certificate (EPC) in England and Wales had a rating of C or D. In England, there were over 394,000 buildings registered with a C rating since the last quarter of 2008. These figures do not show, however, the overall number of commercial buildings in England and Wales, but the number of buildings with an EPC in those territories.

Dwellings with EPC Band C or above in England and Wales, by property type, tenure, property age and whether new or existing.

If you want to give feedback on this dataset, or wish to request it in another form (e.g csv), please fill out this survey here. We are a not-for-profit research organisation keen to see how others use our open models and tools, so all feedback is appreciated! It's a short form that takes 5 minutes to complete.

This dataset aligns with the work published in Centre for Net Zero's report "Hitting the Target". In this work, we simulate a range of interventions to model the situations in which we believe the UK will meet its 600,000 heat pump installation per year target by 2028. For full modelling assumptions and findings, read our report on our website.

The code for running our simulation is open source here.

This dataset contains over 9 million households that have been address matched between Energy Performance Certificates (EPC) data and Price Paid Data (PPD). The code for our address matching is here. Since these datasets are Open Government License (OGL), this dataset is too. We basically model specific columns from various datasets, as set out in our methodology section in our report, to simplify and clean up this dataset for academic use. License information is also available in the appendix of our report above.

The EPC data loaders can be found here (the data is here) and the rest of the schemas and data download locations can be found here.

Note that this dataset is not regularly maintained or updated. It is correct as of January 2022. The data was curated and tested using dbt via this Github repository and would be simple to rerun on the latest data.

The schema / data dictionary for this data can be found here.

Our recommended way of loading this data is in Python. After downloading all "parts" of the dataset to a folder. You can run:

import pandas as pd


data = pd.read_parquet("path/to/data/folder/")

To gain insight into the energy efficiency status of all domestic properties with an EPC in England and Wales

In 2022, the majority of owner-occupied homes in the United Kingdom (UK) had energy efficiency rating D. Local authority and housing association homes were the most energy efficient, with the largest share of properties with rating A, B, or C. The energy performance certificate is legally required when buying or renting a home and shows the energy efficiency of a property.

Energy Performance Certificates (EPCs):An EPC provides information about how energy efficient a building is, and how the efficiency could be improved. Buildings are rated on a scale from A to G, with A being the most efficient. The EPC also provides:information on measures which could be made to improve the energy efficiency of the buildingan indicative cost for each improvementThe EPC is accompanied by a recommendations report which provides more detailed information about improvement measures. For further support and guidance, please visit the following: Scottish Government's EPC GuidanceStirling Council's Publication Schedule and Data:EPC Registry data is usually published quarterly and as an individual dataset - Stirling will publish a single dataset, updated incrementally with each released quarter, for its respective reporting year. For example, In March 2025, the latest release contains data up to and including Q3 2024 (end of September 2024).Copyright Information:Please ensure any user of this data has read, and complies with, the copyright information attached to each dataset. The Scottish Government has published these data as Environmental Information on the energy performance of buildings in Scotland. Publication is intended to contribute to delivering the Scottish Government’s policies to mitigate the effects of climate change and reduce greenhouse gas emissions and provide data to facilitate improvements in the energy efficiency of buildings through research, improved management, and innovation.Non-Address DataAll data fields other than the address and postcode data (UPRN, ADDRESS1, ADDRESS2, POST_TOWN & POSTCODE) included within this dataset are licensed under the Open Government Licence v3.0Address DataAny use of address data (UPRN, ADDRESS1, ADDRESS2, POST_TOWN & POSTCODE) not specified in Royal Mail’s copyright notice (refer to dataset description and licence) or covered by one of the copyright exceptions will require an appropriate licence.

Management Information: environmental data on the Domestic Energy Performance Certificate (EPC) and Recommendations Report for each current record held on the Scottish EPC Register from Q1 2015 to Q4 2024. Data extracted March 2025.

Statistics on the number of dwellings that have been certified to the standards set out in the Code Technical Guide, in which local authority area, at which Code level and whether the homes are registered as private or public sector. Statistics on Energy Performance Certificates are based on SAP (Standard Assessment Procedure) energy efficiency ratings of dwellings in England and Wales, with breakdown by region and dwelling type.

This release presents official statistics on energy performance of buildings in England and Wales, including energy efficiency ratings, environmental impact ratings, energy usage, costs and emissions of dwellings and non-dwellings. The statistics will derive from two datasets - Energy Performance Certificates (EPCs) and Display Energy Certificates (DECs). Published by Department for Communities and Local Government.

Data on the energy efficiency of dwellings, environmental impact score and estimated CO2 emissions in England and Wales at the middle layer super output area level. These are broken down by property type, tenure, age of property and whether a dwelling is new or existing.

The majority of office real estate stock across the major office markets in the United Kingdom (UK) in 2021 had an EPC rating of "C" or below. The EPC rating shows how energy efficient a building is, with A+ being the highest and G the lowest rating. Manchester and the City of London were the markets with the most energy efficient office real estate stock. In the City of London, approximately 18.5 percent of office space had an EPC rating of B or above. In Edinburgh, on the other hand, this share was 10.5 percent.
