Warm Homes: Social Housing Fund statistics - August 2026

Published 27 August 2026

Applies to England

Introduction

In January 2026 the government published its Warm Homes Plan to upgrade up to 5 million homes by 2030. The Warm Homes: Social Housing Fund (WH:SHF) is part of this plan, installing energy efficiency upgrades and low-carbon heating measures in English social housing. The scheme provides funding to local authorities, combined authorities, registered providers of social housing, and registered charities that own social housing in England.

WH:SHF is also known as WH:SHF Wave 3. Draft Guidance for this scheme was published on 13 May 2024, and social housing landlords had the opportunity to ask clarification questions by mid-June 2024. The delivery window opened in April 2025.

Further details on the WH:SHF can be found in the scheme’s guidance.

What you need to know about these statistics

The Methodology and Background Note explains how these statistics are compiled, their limitations, and how they should be interpreted.

The figures cover activity delivered in England under WH:SHF from the start of the scheme to the data cut-off date for this release. They are based on monthly returns submitted by Grant Recipients through the Grant Reporting System and linked to records of measures lodged on the TrustMark data warehouse. A Grant Recipient is an organisation awarded funding under the scheme and responsible for delivering upgrades and reporting scheme activity.

TrustMark lodgements provide evidence that an installation has been lodged by a registered installer, but they are not used directly as the basis for the published DESNZ measure and household statistics. Linked Grant Recipient returns are the main source of the published figures because they combine TrustMark evidence with scheme reporting information. A measure is eligible for inclusion only where the relevant records can be linked, processed and passed through the required validation checks.

The statistics reflect the records received, linked and processed by the cut-off date for each release. They do not necessarily capture all activity that has taken place. Some activity may be reported by Grant Recipients after the cut-off, some returns may not yet have been linked to TrustMark lodgements and some records may need further validation before they can be included. The latest month shown is therefore likely to be underestimated but is included to provide the best estimate available at the time of publication.

From the August 2026 statistics onwards, where a linked Grant Recipient record is incomplete, information from the corresponding TrustMark lodgement may be used to complete the record where appropriate. For example, a TrustMark installation date may be used where the installation date is missing from the linked Grant Recipient record.

All figures are provisional and may be revised in future releases as additional returns are submitted, records are linked to TrustMark lodgements, and data quality issues are resolved. Revisions are expected to be mainly upward in early releases.

What these statistics can and cannot tell users

What these statistics can tell you:

• the number of measures installed, and households upgraded that have been reported by Grant Recipients, linked to TrustMark lodgements and passed validation checks by the data cut-off date
• how delivery is distributed across measure types and regions
• how reported delivery changes over time and between statistical releases as additional data is received and processed

What these statistics cannot tell you:

• the total volume of activity that has taken place on the ground at the point of publication
• the full level of activity in the most recent reporting period, which might be underestimated
• the volume of activity that has been installed but not yet reported, linked or validated, although the number of lodgements in the TrustMark data warehouse are given as context below
• the performance of individual Grant Recipients (data is not disaggregated by Grant Recipients in this official statistics release)
• future scheme delivery volumes and expenditure through extrapolation

Key statistics

Total homes upgraded and measures installed

• The data contained in these statistics is based on returns submitted by 94 of the 138 participating Grant Recipients to the Grant Reporting System by mid-August 2026, reporting activity to the end of July 2026.
• There have been around 25,770 measures reported by Grant Recipients in around 12,900 households in the WH:SHF up to the end of July 2026.

The data used in this chart can be found in Table 1 of the accompanying tables.

Comparison with TrustMark data

• There were around 35,700 WH:SHF measures lodged in the TrustMark data warehouse up to the end of July 2026, covering around 17,500 households.
• The number of TrustMark lodgements is higher than the published WH:SHF figures because measures may be lodged on TrustMark before the corresponding Grant Recipient return has been submitted, linked and validated.
• These TrustMark figures are provided for context and indicate additional installation activity that may not yet be reflected in the published official statistics. TrustMark lodgements contribute to the published figures only where they can be linked to Grant Recipient reporting and pass the required validation checks.

Delivery by measure type

• Across the WH:SHF, solar PV was the most common type of measure, accounting for 36% of installations reported by Grant Recipients, followed by loft insulation (28%) and heating controls (8%) measures (Figure 2).

Figure 2: Type of measures installed in the WH:SHF

The data used in this chart can be found in Table 2 of the accompanying tables. Other insulation includes cavity wall insulation, solid wall insulation and flat roof insulation. Other low carbon heating and other electricity related measures include all other forms of low carbon heating or electricity related measures not listed.

Delivery by region

• The North East region has the most homes upgraded through WH:SHF (19% of total WH:SHF homes reported by Grant Recipients), followed by the North West (15%), West Midlands and East Midlands (each at 13%).

• Households in the North West have received the highest number of measures per household on average at 2.42.

• The regions have significantly different numbers of households and participating Grant Recipients that might have an impact on these trends.
