Household Energy Efficiency Data 2023
Each month the Department for Energy Securuty and Net Zero (DESNZ) publish updated data on performance of the various funding schemes and streams across Great Britain on a rolling 3 month basis.
In addition to this at the end of March they publish a full report on the performance for the previous calendar year in its entirity. The 2023 report has now (28th March 2024) been published – and it makes interesting reading!

Household Energy Efficiency Data 2023 – Report Contents
This annual report presents detailed statistics on the Energy Company Obligation (ECO), the Green Deal (GD) and insulation levels in Great Britain, up to the end of 2023.
This is the ninth annual release following the user consultation that took place in autumn 2015 on GD, ECO and insulation level statistics. It includes further analysis and geographical breakdowns of ECO measures. It also includes ECO delivery costs, estimated carbon and energy savings from measures installed, the GD supply chain, and estimates of home insulation levels.
As ever this is a comprehensive publication covering the following topics across 33 pages:
- Energy Efficiency Trends
- Measures By Type
- ECO Household Characteristics
- ECO Costs
- Green Deal
- Estimates of Home Insulation LevelsBenefits Monitoring
- Benefits Monitoring
- Technical Information
- Household Energy Efficiency Schemes
- Further Information
The schemes they cover are both historical and current and include:
- The Energy Company Obligation (ECO) – introduced in January 2013 to reduce energy consumption and
support people at greater risk of living in fuel poverty.- ECO1 from 1 January 2013
- ECO2 from April 2015
- ECO Help-to-Heat from April 2017
- ECO3 from 3 December 2018
- ECO4 (current) from July 2022
- The Green Deal (GD) – a government initiative designed to help homeowners install energy efficiency measures into their properties, with the costs of these measures are paid back through their energy bill over a period of time.
- The Green Homes Grant Vouchers (GHGV) scheme from September 2020 – closed March 2021.
- The Green Homes Grant Local Authority Delivery (LAD) scheme from 2020 with £500 million of funding to support the energy efficiency upgrades of low-income households across England.
- The Sustainable Warmth (SW) scheme from early 2022 to further support the energy efficiency upgrades of low income households across England.
- The Social Housing Decarbonisation Fund (SHDF) from August 2021 energy efficiency upgrades to a significant amount of the social housing stock currently below Energy Performance Certificate (EPC) C.
- The Great British Insulation Scheme – launched March 2023. £1 billion scheme to help around 300,000 households across the country with the cost of installing new home insulation.
Household Energy Efficiency Data 2023 – Key Headlines
The report extracted the following statistics and highlighted them as of particular relevence:
- From 2013 to the end of 2023, around 4.1 million energy efficiency measures were installed in 2.7 million properties in Great Britain through various government support schemes: Energy Company Obligation (ECO), the Green Deal (GD) Framework, Green Homes Grant Vouchers (GHGV), Local Authority Delivery (LAD), Home Upgrade Grant (HUG), Social Housing Decarbonisation Fund (SHDF) and the Great British Insulation Scheme (GBIS).
- During 2023, around 318,600 energy efficiency measures were installed through these schemes, an increase of 49 per cent compared with 2022.
- However, around 83,500 households were upgraded across all schemes, a decrease of 17 per cent compared with 2022 – this is largely driven by ECO4’s whole-house retrofit approach of multiple installations per household.
- ECO remains the largest energy efficiency scheme. Measures delivered through ECO accounted for 83 per cent of all measures installed in 2023. During 2023, ECO delivered 265,000 measures – an increase of 61 per cent compared to 2022 – as delivery under ECO4 continued to grow, following its start in April 2022 after the closure of ECO3.
- In 2023, 23,600 measures were delivered through SHDF, 20,400 measures through LAD, 5,600 measures through HUG, and 4,000 measures through GBIS.
- At the end of 2023, it is estimated that 15.0 million properties in Great Britain had cavity wall insulation (70 per cent of properties with a cavity wall), 17.3 million had loft insulation (67 per cent of properties with a loft) and 833,000 had solid wall insulation (10 per cent of properties with solid wall).

Energy Efficiency Trends:
- From 2013 to 2023, 4.1 million energy efficiency measures were installed in 2.7 million properties through various government support schemes.
- In 2023, 318,600 measures were installed through ECO, LAD, HUG, SHDF and GBIS.
- In 2023, 265,000 ECO measures were installed in 50,300 first-time households
Measures By Type:
- Across all schemes, 57 per cent of measures were for insulation and 43 per cent for heating.
- In 2023, the most popular group of measures under ECO was ‘Other heating’, with 139,500 measures installed – the majority of which were heating controls
ECO Household Characteristics:
- Under ECO, 81 per cent of measures were installed in properties using gas as their main fuel type.
- The majority (71 per cent) of households where measures were installed were houses.
- The most common tenure was owner-occupied, accounting for around 70 per cent of households
Regional Trends:
- To date, just over nine per cent of households in Great Britain have had an ECO measure installed.
- Across ECO, nearly one fifth (18 per cent) of ECO measures were installed in the North West of England.
- The North West region also had the most measures installed under LAD and SHDF Wave 1
ECO Costs:
- The total ECO costs reported by suppliers (both delivery and administrative) to the end of 2023 were £7.95 billion.
- Delivery costs in 2023 were £1.48 billion.
- Up to the end of December 2023 the average cost of delivering the ECO4 obligation, not including ECO3 interim, was around £21.69 per £ annual bill savings.
Green Deal:
- A total of 13,867 Green Deal Plans since the Green Deal began in 2013.
- Around a third of plans (34 per cent) are classified as ‘Completed’ (all measures installed and paid off).
- In 2023, 359 plans were ‘Completed’.
Estimates of Home Insulation Levels in Great Britain:
- 7.8 million major professional insulation measures (cavity wall, loft and solid wall) have been installed through ECO and other government supported domestic energy efficiency schemes since 2009.
- Of the estimated 21.3 million homes with cavity walls, 70 per cent have cavity wall insulation
- Of the estimated 25.8 million homes with lofts, 67 per cent have loft insulation.
- Of the estimated 8.5 million homes with solid walls, 10 per cent have solid wall insulation.
Benefits Monitoring:
- To the end of December 2023, provisional estimated annual carbon savings of measures installed through LAD, HUG, GHGV and SHDF was up to 0.0578 MtCO2.
- To the end of December 2023, provisional estimated annual energy savings of measures installed through LAD, HUG, GHGV and SHDF was up to 292 GWh.
- To the end of December 2023, provisional estimated annual bill savings of measures installed through LAD, HUG, GHGV and SHDF was £13.4m.
