As of the first quarter of 2025, most housing units with a valid certificate in England and Wales had a D rating in energy efficiency and environmental impact. Meanwhile, there were around ******* housing units in England and Wales with an environmental impact rating of A, meaning that they were very sustainable. However, it should be considered that these figures do not show the overall number of homes in these regions, just the ones with an energy efficiency rating or an environmental impact rating issued in the past ten years.

In 2023, the majority of owner-occupied homes in the United Kingdom (UK) had energy efficiency rating of C. Local authority and housing association homes were the most energy efficient, with the largest share of properties with a rating of **********. The energy performance certificate is legally required when buying or renting a home and shows the energy efficiency of a property.

Most new homes included in the energy performance certificate (EPC) register in England and Wales in 2024 and the first quarter of 2025 had a * rating. The second most common rating band was * for England and Wales. Meanwhile, homes with a rating ranging from E to G amounted to less than *** percent each. The percentages shown here indicate the relative weight of each energy efficiency band among new EPC registrations. Housing units that have not been registered are not considered.

A survey of the design quality, as measured by CABE Building For Life criteria, of affordable housing in England, commissioned by the Homes and Communities Agency.

Energy efficiency of dwellings, estimated CO2 emissions and main fuel type of central heating in England and Wales for five-year groups, by property type, tenure and whether new or existing.

This dataset provides detailed property-level information for over 3,800 UK households with corresponding Heat Transfer Coefficient (HTC) data, enabling in-depth analysis of how physical building characteristics influence energy efficiency and heat retention.

Each record includes the following attributes: 1. Postcode: Area-level geographic identifier for spatial and regional analysis. 2. Total Floor Area (m²): Size of the property, providing essential context for normalising heat performance and consumption. 3. Current Energy Rating: The property’s Energy Performance Certificate (EPC) band (A–G), indicating overall efficiency. 4. Construction Age Band: The building’s construction period (e.g., 1930–1949, 2007 onwards), offering insight into design standards and insulation quality.

By linking these characteristics with HTC values, this dataset enables powerful applications in: - Energy Efficiency Modelling: Correlate EPC ratings and HTC scores to assess how building design affects real-world performance. - Retrofit Planning & Policy Analysis: Identify and prioritise homes most in need of energy upgrades or thermal improvements. - Academic & Commercial Research: Support studies into the relationship between construction age, building size, and thermal performance. - Sustainability & Net-Zero Strategy: Provide evidence-based insights for government, energy agencies, and developers to reduce housing stock emissions.

The dataset is fully anonymised and GDPR-compliant, ensuring privacy while maintaining analytical value. It is part of Chameleon Technology’s broader energy data offering and complements the HTC dataset, allowing seamless cross-analysis between property traits and thermal efficiency.

The number of households included continues to grow, expanding coverage and analytical potential across diverse UK housing types.

Office for National Statistics' national and subnational Census 2021. Occupancy rating for roomsThis dataset provides Census 2021 estimates that classify households in England and Wales by occupancy rating based on the number of rooms in the household. The estimates are as at Census Day, 21 March 2021. Occupancy rating for rooms definition: Whether a household's accommodation is overcrowded, ideally occupied or under-occupied. This is calculated by comparing the number of rooms the household requires to the number of available rooms.The number of rooms the household requires uses a formula which states that:one-person households require three rooms comprised of two common rooms and one bedroomtwo-or-more person households require a minimum of two common rooms and a bedroom for each person inline with the Bedroom StandardPeople who should have their own room according to the Bedroom Standard are:married or cohabiting couplesingle parentperson aged 16 years and overpair of same-sex persons aged 10 to 15 yearsperson aged 10 to 15 years paired with a person under 10 years of the same sexpair of children aged under 10 years, regardless of their sexperson aged under 16 years who cannot share a bedroom with someone in 4, 5 or 6 aboveAn occupancy rating of: -1 or less: implies that a household's accommodation has fewer rooms than required (overcrowded)+1 or more: implies that a household's accommodation has more rooms than required (under-occupied)0: suggests that a household's accommodation has an ideal number of roomsThe number of rooms is taken from Valuation Office Agency (VOA) administrative data for the first time in 2021. The number of rooms is recorded at the address level, whilst the 2011 Census recorded the number of rooms at the household level.This means that for households that live in a shared dwelling, the available number of rooms are counted for the whole dwelling in VOA, and not each individual household.VOA's definition of a room does not include bathrooms, toilets, halls or landings, kitchens, conservatories or utility rooms. All other rooms, for example, living rooms, studies, bedrooms, separate dining rooms and rooms that can only be used for storage are included. Please note that the 2011 Census question included kitchens, conservatories and utility rooms while excluding rooms that can only be used for storage. To adjust for the definitional difference, the number of rooms required is deducted from the actual number of rooms it has available, and then 1 is added.Quality information: It is inappropriate to measure change in number of rooms from 2011 to 2021, as Census 2021 used Valuation Office Agency data for this variable. Instead use Census 2021 estimates for number of bedrooms for comparisons over time.Comparability with 2011: Not comparable. This variable cannot be compared with the variable used in the 2011 Census.

CONSOLIDATED DATA ON EPC AND CO2 EMISSIONS OF 21 MILLION RESIDENTIAL PROPERTIES IN ENGLAND. Energy Performance Certificates (EPC) in England gives a property an energy efficiency rating from A (most efficient) to G (least efficient) and is valid for 10 years. While the rating itself is ordinal, the underlying database is one of the richest data on individual residential properties. With 92 features ranging from CO2 emissions to lighting efficiency. It can be an invaluable source for Bank’s wanting to come up with their financed emissions (Scope 3 category 15). While the data is somehow disjointedly available on UK government’s EPC open data portal, it becomes difficult to consolidate. With some effort, I have been able to consolidate this data. It’s a huge dataset of nearly 25 million records and 94 features of over 21 million properties in England. It’s freely available on Kaggle: . Feel free to download and use it for estimating baseline emissions. Particularly useful for institutions and banks (especially GCC) which have financed real estate in England.

This dataset represents ethnic group (19 tick-box level) by dwelling tenure and by occupancy rating, for England and Wales combined. The data are also broken down by age and by sex.

The ethnic group that the person completing the census feels they belong to. This could be based on their culture, family background, identity, or physical appearance. Respondents could choose one out of 19 tick-box response categories, including write-in response options.

Total counts for some population groups may not match between published tables. This is to protect the confidentiality of individuals' data. Population counts have been rounded to the nearest 5 and any counts below 10 are suppressed, this is signified by a 'c' in the data tables.

"Asian Welsh" and "Black Welsh" ethnic groups were included on the census questionnaire in Wales only, these categories were new for 2021.

This dataset provides Census 2021 estimates that classify usual residents in England and Wales by ethnic group. The estimates are as at Census Day, 21 March 2021.

All housing data in these tables do not include commual establishments.

This dataset provides Census 2021 estimates that classify households in England and Wales by number that are HMOs by occupancy rating (bedrooms). The estimates are as at Census Day, 21 March 2021.

Improvements to the Census address frame allowed us to accurately list multiple household spaces within the same building. This means the data are more often counted as distinct households within separate dwellings reflecting living arrangements. Read more about this quality notice.

Area type

Census 2021 statistics are published for a number of different geographies. These can be large, for example the whole of England, or small, for example an output area (OA), the lowest level of geography for which statistics are produced.

For higher levels of geography, more detailed statistics can be produced. When a lower level of geography is used, such as output areas (which have a minimum of 100 persons), the statistics produced have less detail. This is to protect the confidentiality of people and ensure that individuals or their characteristics cannot be identified.

Coverage

Census 2021 statistics are published for the whole of England and Wales. Data are also available in these geographic types:

• country - for example, Wales
• region - for example, London
• local authority - for example, Cornwall
• health area – for example, Clinical Commissioning Group
• statistical area - for example, MSOA or LSOA

Households of multiple occupancy (HMO)

A dwelling where unrelated tenants rent their home from a private landlord is a HMO, if both of the following apply:

• at least three unrelated individuals live there, forming more than one household
• toilet, bathroom or kitchen facilities are shared with other tenants

A small HMO is shared by 3 or 4 unrelated tenants. A large HMO is shared by 5 or more unrelated tenants.

Occupancy rating for bedrooms

Whether a household's accommodation is overcrowded, ideally occupied or under-occupied. This is calculated by comparing the number of bedrooms the household requires to the number of available bedrooms.

The number of bedrooms the household requires is calculated according to the Bedroom Standard, where the following should have their own bedroom:

1. adult couple
2. any remaining adult (aged 21 years or over)
3. two males (aged 10 to 20 years)
4. one male (aged 10 to 20 years) and one male (aged 9 years or under), if there are an odd number of males aged 10-20
5. one male aged 10-20 if there are no males aged 0-9 to pair with him.
6. repeat steps 3-5 for females
7. two children (aged 9 years or under) regardless of sex
8. any remaining child (aged 9 years or under)

An occupancy rating of:

• -1 or less implies that a household’s accommodation has fewer bedrooms than required (overcrowded)
• +1 or more implies that a household’s accommodation has more bedrooms than required (under-occupied)
• 0 suggests that a household’s accommodation has an ideal number of bedrooms

This dataset provides Census 2021 estimates that classify households in England and Wales by occupancy rating (rooms) and by tenure. The estimates are as at Census Day, 21 March 2021.

It is inappropriate to measure change in number of rooms from 2011 to 2021, as Census 2021 used Valuation Office Agency data for this variable. Instead use Census 2021 estimates for number of bedrooms for comparisons over time. Read more about this quality notice.

There is evidence of people incorrectly identifying their type of landlord as ”Council or local authority” or “Housing association”. You should add these two categories together when analysing data that uses this variable. Read more about this quality notice.

Lower tier local authorities

Lower tier local authorities provide a range of local services. There are 309 lower tier local authorities in England made up of 181 non-metropolitan districts, 59 unitary authorities, 36 metropolitan districts and 33 London boroughs (including City of London). In Wales there are 22 local authorities made up of 22 unitary authorities.

Coverage

Census 2021 statistics are published for the whole of England and Wales. However, you can choose to filter areas by:

• country - for example, Wales
• region - for example, London
• local authority - for example, Cornwall
• health area – for example, Clinical Commissioning Group
• statistical area - for example, MSOA or LSOA

Occupancy rating for rooms

Whether a household's accommodation is overcrowded, ideally occupied or under-occupied. This is calculated by comparing the number of rooms the household requires to the number of available rooms.

The number of rooms the household requires uses a formula which states that:

• one-person households require three rooms comprised of two common rooms and one bedroom

• two-or-more person households require a minimum of two common rooms and a bedroom for each of the following:

  1. married or cohabiting couple
  2. single parent
  3. person aged 16 years and over
  4. pair of same-sex persons aged 10 to 15 years
  5. person aged 10 to 15 years paired with a person under 10 years of the same sex
  6. pair of children aged 10 years, regardless of their sex
  7. person aged under 16 years who cannot share a bedroom with someone in 4, 5 or 6 above

An occupancy rating of:

• -1 or less implies that a household’s accommodation has fewer rooms than required (overcrowded)
• +1 or more implies that a household’s accommodation has more rooms than required (under-occupied)
• 0 suggests that a household’s accommodation has an ideal number of rooms

The number of rooms is taken from Valuation Office Agency (VOA) administrative data for the first time in 2021. The number of rooms is recorded at the address level, whilst the 2011 Census recorded the number of rooms at the household level. This means that for households that live in a shared dwelling, the available number of rooms are counted for the whole dwelling in VOA, and not each individual household.

VOA’s definition of a room does not include bathrooms, toilets, halls or landings, kitchens, conservatories or utility rooms. All other rooms, for example, living rooms, studies, bedrooms, separate dining rooms and rooms that can only be used for storage are included. Please note that the 2011 Census question included kitchens, conservatories and utility rooms while excluding rooms that can only be used for storage. To adjust for the definitional difference, the number of rooms required is deducted from the actual number of rooms it has available, and then 1 is added.

Tenure of household

Whether a household owns or rents the accommodation that it occupies.

Owner-occupied accommodation can be:

• owned outright, which is where the household owns all of the accommodation
• with a mortgage or loan
• part-owned on a shared ownership scheme

Rented accommodation can be:

• private rented, for example, rented through a private landlord or letting agent
• social rented through a local council or housing association

This information is not available for household spaces with no usual residents.
