In quarter 2 2024, the local authority with the largest increases in EPCs lodged for new dwellings compared to the same quarter in 2023, was in Neath Port Talbot (162%), while the largest decrease was in Wrexham (-62%).
2. Introduction
This statistical release presents Official Statistics in development based on Energy Performance Certificates (EPCs) issued for domestic and non-domestic buildings and Display Energy Certificates (DECs) issued for buildings occupied by public authorities. The certificates are lodged on the Energy Performance of Buildings Register (The Register) for England and Wales.
Through most of the release, the figures have been split into England only and Wales only. If England and Wales combined figures are required, they are available in the ‘live’ tables published alongside this release. Throughout the report, numbers have been rounded to the nearest thousand. Percentage changes have been calculated using unrounded figures. Due to rounding, individual figures may not add up to the total.
2.1 Energy Performance Certificates
An Energy Performance Certificate (EPC) indicates the energy efficiency of a building. The assessments are banded from A to G, where A (or A+ for non-domestic properties) is the most efficient in terms of likely fuel costs and carbon dioxide emissions. An EPC is required when a building is constructed, sold, or let and if a valid certificate is not already in place. The purpose of an EPC is to show prospective tenants or buyers the energy efficiency of the property. The requirement for EPCs was introduced in phases and fully implemented for all properties by autumn 2008. EPCs are valid for 10 years.
2.2 Official Statistics in development
Official Statistics in development are defined in the Code of Practice for Statistics as “new official statistics undergoing evaluation”. They are published in order to involve users and stakeholders in their development and as a means to build in quality at an early stage.
These statistics are based on information from EPCs lodged on the Register. This administrative data is subject to continuing quality assurance and improvement (see Technical Notes on Data Quality). They have been released because they have been judged to be of immediate value to interested parties and to encourage user feedback.
2.3 Display Energy Certificates
A Display Energy Certificate (DEC) is only required for buildings occupied by public authorities over 250 square meters where that building is frequently visited by the public.
DECs show the actual energy consumption of a building and are accompanied by reports which provide recommendations on potential energy saving measures. DECs last for one year for buildings with a total useful floor area more than 1,000 square metres, or 10 years when the total useful floor area is over 250 square metres and up to 1,000 square metres.
DECs that can be identified as ‘voluntary’ - some private sector organisations may choose to have a DEC even though they are not mandated by the regulations - may affect statistical and data outputs. Therefore, ‘voluntary DECs are excluded from the published dataset.
3. Coverage
The Register does not hold records for all dwellings in England and Wales, as not every dwelling has an EPC (these are only required when a dwelling is constructed, sold or let).
Some dwellings may have changed tenure since the date of their latest EPC. For instance, dwellings that had an EPC for reasons other than being let may have since entered the private or social rented sector.
ONS have led on an exploratory look at the EPC data comparing with the census to determine the percentage of dwellings covered by an Energy Performance Certificate in England and Wales, using Census 2021 data. Based on their analysis EPCs cover around 60% of the housing stock in England 55% in Wales. There is a similar proportion across all regions in England.
4. How the data should be used
4.1 How the data should be used
- To evaluate trends in the energy performance of buildings in England and Wales that have had an Energy Performance Certificate (EPC)
- To assess changes in the number of EPCs between the same quarters across years e.g. Q2 2024 and Q2 2023
- As an early indication of new housing supply
4.2 How the data should not be used
- To count the total building stock in England and Wales. The Register does not hold data for every building, only those with an EPC
- To compare across quarters within a year. The data have a seasonal pattern and should only be compared between the same quarters across years e.g. Q2 2024 and Q2 2023
- The data are aggregated and will not comment on individual buildings
- To track energy prices. The methodology used to assess energy efficiency does not take into account changes in energy prices
5. England and Wales
In the quarter April to June 2024, 458,000 EPCs were lodged on the Register for both domestic and non-domestic properties in England and Wales, a 6% decrease from quarter 2 in 2023 (Live Table A1).
In April to June 2024, the total number of EPCs lodged for new dwellings in England and Wales had a 5% decrease to 56,000, compared to the equivalent quarter in 2023 (Live Table NB1). There was a 3% decrease to 375,000 for existing dwellings EPCs lodged for that quarter (Live Table EB1).
6. England quarterly figures
Quarterly figures are not seasonally adjusted and should be compared to the same quarter as the previous year to see trends.
6.1 New and existing dwellings
From April to June 2024, 412,000 EPCs were lodged on the Register covering all domestic dwellings (sales, lets and new dwellings) in England. This represents a 3% decrease on the same quarter 2023, when there were 426,000 domestic lodgements (Live Table D1).
The majority of domestic EPCs were for the sale or let of existing dwellings. In April to June 2024, 357,000 EPCs for existing dwellings were lodged on the Register in England, a 3% decrease, while 55,000 EPCs were lodged for new dwellings (including new builds, conversions and change of use), a 5% decrease on the same quarter in 2023 (Live Table EB1 and NB1).
Table 1: Number of EPCs for new and existing dwellings, England, April to June 2024
| New dwellings: Number | New dwellings: Change since equivalent quarter | Existing dwellings: Number | Existing dwellings: Change since equivalent quarter | All domestic dwellings: Number |
|---|---|---|---|---|
| 55,000 | 5% decrease | 357,000 | 3% decrease | 412,000 |

Note: New dwellings and existing dwellings may not add up to all domestic dwellings due to rounding
Energy Performance Certificates for domestic properties show an Energy Efficiency Rating (EER) based on estimated fuel costs and an Environmental Impact Rating (EIR) based on CO2 emissions. Both measures are estimated from the characteristics of the property. The numerical ratings are then banded A to G, with A being the most energy efficient and G the least. In general, the higher the EER or EIR rating, the lower the fuel bills and CO2 emissions are likely to be.
For both the EER and the EIR, the largest proportion of lodgements for existing domestic properties in England were in bands C and D. New properties in England tended to be more energy efficient, with the majority in band B (Figures 1 and 2).
In England, from April to June 2024, most (79%) new properties were given a B EER rating. Existing dwellings were more likely to be given a C or D EER (85%), compared to 12% of new dwellings. (Live Tables EB1 and NB1).

Note: Percentage changes have been calculated using unrounded figures, therefore proportions may not add to 100%.
Figure 2: Environmental impact ratings (EIR): existing and new domestic properties, England, April to June 2024
Note: Percentage changes have been calculated using unrounded figures, therefore proportions may not add to 100%.
6.2 Non-domestic properties
A non-domestic property is a building that is not a dwelling, such as a retail unit or office.
In April to June 2024, 25,000 EPCs were lodged for non-domestic properties, a 34% decrease compared with the corresponding quarter in 2023. However, the number of non-domestic EPCs for quarter 2 of 2023 were high compared to lodgement numbers over the last 5 years. This is likely because the requirement that all privately rented non-domestic properties have at least an EPC E rating, unless they have registered a valid exemption, came into effect on 1st April 2023.
The distribution by EPC band is shown in Figure 3. Non-domestic buildings have an additional A+ band but numbers are too small to report so are combined with those receiving an A rating. An A+, A or B rating was given to 41% of properties (Live Table A).

Note: Percentage changes have been calculated using unrounded figures, therefore proportions may not add to 100%.
6.3 Display Energy Certificates (DECs)
Properties over 250 square meters occupied by a public authority and frequently visited by the public must display a Display Energy Certificate (DEC). DECs show the actual energy consumption of a building and are accompanied by reports which provide recommendations on potential energy saving measures.
From April to June 2024, 8,000 DECs were lodged in England, a 12% increase compared with the corresponding quarter in 2023 (Live Table DEC1).
The distribution of DECs by Energy Performance Operational Ratings is shown in Figure 4. The highest proportions of DECs were in bands C (36%) and D (31%).

Note: Percentage changes have been calculated using unrounded figures, therefore proportions may not add to 100%.
6.4 Long term trends by transaction type
Figure 5 shows the number of domestic EPCs by transaction type, i.e. the reason for the EPC being produced, as well as the total number. The transaction types have been grouped. For example, lodgements for social and private rentals are grouped together.
The chart shows fluctuations in different transaction types based on the total number of EPCs lodged. For example, there is a seasonal pattern with fewer home sales at Christmas, which can be seen in the number of EPC lodgements. This seasonality affects the total for EPCs, particularly up to the end of 2012. At the end of 2012 the recast of EU Directive also led to changes to the Energy Performance of Buildings regulations (the regulations). It also shows how the total number of EPCs were influenced by lodgements made for energy efficiency programmes and similar schemes, as well as lodgements for other reasons, particularly in 2013, 2014 and 2015.

Note: The categories collected changed in 2012, leading to a break in the chart indicated by the line.
7. England annual figures
7.1 New and Existing dwellings
These figures are not seasonally adjusted and give annual estimates for the number of energy performance certificates over a rolling 12-month period. These can be used to make year on year comparisons.
In the 12 months to June 2024, in England, 1,566,000 domestic EPCs were lodged, a 5% decrease on the previous 12 months (Live Table D1).
In the year to June 2024, 1,336,000 EPCs for existing dwellings were lodged on the register in England, a 5% decrease on the equivalent 12 months preceding June 2023. EPCs for new dwellings (including new builds, conversions and change of use) had a 5% decrease to 230,000 (Live Tables EB1 and NB1).
7.2 Non-domestic properties
In the year ending June 2024, 109,000 non-domestic EPCs were lodged, a 20% decrease on the number lodged during the previous year (Live Table A).
7.3 Display Energy Certificates (DECs)
In the year ending June 2024, 34,000 DECs were lodged in England, representing a 7% increase compared with the previous year (Live Table DEC1).
8. England sub-national figures
This section presents a quarterly snapshot of domestic EPCs at sub-national level in England. For data at a local authority level with maps, see the EPC interactive dashboard.
8.1 Regional figures
There is much variability across regions in the energy efficiency of dwellings, this is largely related to the type and age of the dwelling stock.
In the quarter ending June 2024, the largest increase in EPCs lodged for new dwellings compared to the same quarter in 2023, was in London (13%), while the largest decrease was in East of England (-17%), (Live Table NB1). For existing dwellings, the largest increase was 32% in the North West (Live Table EB1). The largest decrease was in London (-23%).

9. Wales quarterly figures
Quarterly figures are not seasonally adjusted and should be compared to the same quarter in the previous year to see trends.
9.1 New and existing dwellings
From April to June 2024, 19,000 EPCs were lodged on the Register covering domestic properties (sales, lets and new dwellings) in Wales. This represents an 8% decrease on the same quarter 2023, when there were 21,000 domestic lodgements (Live Table D1).
The majority of domestic EPCs were for the sale or let of existing properties. From April to June 2024, 18,000 EPCs for existing dwellings were lodged on the Register in Wales, an 8% decrease, while 2,000 EPCs were lodged for new dwellings (including new builds, conversions and change of use), a 6% decrease compared to the same quarter in 2023 (Live Table EB1 and NB1).
Table 3: Number of EPCs for new and existing dwellings, Wales, April to June 2024
| New dwellings: Number | New dwellings: Change since equivalent quarter | Existing dwellings: Number | Existing dwellings: Change since equivalent quarter | All domestic dwellings: Number |
|---|---|---|---|---|
| 2,000 | 6% decrease | 18,000 | 8% decrease | 19,000 |

Note: New dwellings and existing dwellings may not add up to all domestic dwellings due to rounding
Energy Performance Certificates for domestic properties show an Energy Efficiency Rating (EER) based on estimated fuel costs and an Environmental Impact Rating (EIR) based on CO2 emissions. Both measures are estimated from the characteristics of the property. The numerical ratings are then banded A to G, with A being the most energy efficient and G the least. In general, the higher the EER or EIR rating, the lower the fuel bills and CO2 emissions are likely to be.
For both the EER and the EIR, the largest proportion of lodgements for existing domestic properties in Wales were in bands C and D. New properties in Wales are more energy efficient than existing, with the majority in band B (Figures 7 and 8).
In Wales, from April to June 2024, the majority of new properties were given a B EER (64%). Existing dwellings were more likely to receive a C (43%) or D (36%) rating. (Live Tables EB1 and NB1).

9.2 Non-domestic properties
In April to June 2024, 1,000 EPCs were lodged for non-domestic properties, a 32% decrease compared with the corresponding quarter in 2023 (Live Table A).
The distribution by EPC band is shown in Figure 9. Non-domestic buildings have an additional A+ band but numbers are too small to report. From April to June 2024, an A+, A or B rating was given to 30% of properties. (Live Table A).

9.3 Display Energy Certificates (DECs)
Properties over 250 square meters occupied by a public authority and frequently visited by the public must display a Display Energy Certificate (DEC). DECs show the actual energy consumption of a building and are accompanied by reports which provide recommendations on potential energy saving measures.
From April to June 2024, 500 DECs were lodged, a 38% increase compared to the number of EPCs lodged in the corresponding quarter in 2023 (Live Table DEC1).
The distribution of DECs by Energy Performance Operational Ratings is shown in Figure 9. The highest proportions were in bands C (39%) and D (24%).

14.6 Open data
EPC data at address level in a fully open data format are available at Open Data Communities. Where possible, data are updated within two weeks of this release and as of November 2021 include Unique Property Reference Numbers (UPRNs). To note: local authority allocation is based on ONS geography as at July 2020, whereas this release is based on a more up to date list. Therefore, allocations for authorities within Northamptonshire will differ due to the merger in July 2021. In addition, EPC certificates lodged on the Register and published in the open data does not reflect the recent increase in energy prices. Open data is updated monthly.

Housing supply: indicators of new supply
Quarterly figures on EPCs lodged for new dwellings have followed a similar trend to quarterly new dwelling completions since 2009-10. The number of new dwelling EPCs lodged are higher than quarterly new build completions as they comprise of new dwellings plus dwelling conversions (for example a house into flats) and change of use of an existing building (for example a shop into a house or a barn conversion).
The English Housing Survey is a continuous national survey commissioned by the Ministry of Housing, Communities and Local Government (MHCLG). It collects information about people’s housing circumstances and the condition and energy efficiency of housing in England. It can be used for understanding the energy efficiency of the whole stock as well as the household characteristics of the people living in the homes.
Welsh Housing Conditions Survey
The Welsh Housing Conditions Survey collects information about the condition and energy efficiency of all types of housing in Wales:
-
details of energy saving measures installed in dwellings and breakdowns of construction types
-
the number of dwellings making use of renewable energy
-
heating systems, main fuel type and type of boilers used
-
comparisons between tenures, dwelling types and urban/rural areas
-
comparisons with other UK nations and changes over time.
Scottish House Condition Survey
The Scottish House Condition Survey contains statistics on energy efficiency, based on an annual survey sample of around 3,000 dwellings. This is the primary source of data at a national level on the energy efficiency of the Scottish housing stock.
