Introduction
The Great British Insulation Scheme (GBIS) is a government scheme to help people insulate their homes, make them more energy efficient and save money on their energy bills.
The Government announced the scheme at the end of March 2023. The £1 billion scheme will help around 300,000 households across the country with the cost of installing new home insulation. The scheme is scheduled to run until March 2026.
What you need to know about these statistics
These statistics are based on data provided by Ofgem, covering installations of measures between May 2023 and April 2024. Data are based on the date of completed installation of measures as recorded in the Ofgem register.
All figures are provisional and subject to revision.
Key statistics
Delivery by month
Since the start of GBIS, there have been 11,600 measures installed in 9,400 households up to the end of April 2024.
Measure delivery has continued to increase, with 2,100 measures installed in 1,700 households in April 2024 – the highest level since the scheme began.

Delivery by measure type
The most common measure so far has been cavity wall insulation, accounting for 52% (6,100 measures) of the total 11,600 measures. This was followed by loft insulation which accounted for 20% (2,300 measures) and heating controls which also accounted for 19% (2,200 measures).

Delivery by region
The highest regional delivery has been in the South East and Yorkshire and The Humber (both around 1,700 measures, 15%) and the North West (1,300 measures, 11%).
Figure 3: Proportion of Total Measures Installed by Geographic Region (May 2023 to April 2024)
There have been 9,400 households upgraded under GBIS up to the end of April 2024, meaning they have had at least one measure installed. This is around 34 per 100,000 households (based on estimated household levels for 2022). The rates for Wales and England were slightly higher at 36 and 35 per 100,000 households respectively, while Scotland had a rate of 25 per 100,000. The region with the highest rate was Yorkshire and The Humber with an average of 60 households upgraded per 100,000.
The regional breakdown of upgraded households is largely the same as the regional breakdown of measures installed, as the majority of households (8,300 out of 9,400) have had one measure installed under the scheme. The remaining households have had one or more heating control measures installed (these are secondary measures that can only be installed in households in the low-income eligibility group under the scheme).
GBIS costs
This release includes updated quarterly GBIS costs data, which is provided by energy suppliers.
GBIS delivery costs are the purchase costs of a GBIS measure in a property which may include the costs associated with searching for properties, installation costs and marketing costs by delivery partners involved with promoting the scheme. These costs exclude VAT.
GBIS administrative costs include direct administrative costs (IT set up and maintenance, lead generation and marketing, delivery, commercial strategy and policy, processing, reporting and compliance, and technical monitoring) and in direct administrative costs (legal, finance and HR costs, accommodation and ‘other’).
The total GBIS delivery costs up to the end of March 2024 were around £31.6 million, with an additional £3.8 million in administrative costs. This meant that the total cost of GBIS for the period was £35.4 million.
Up to the end of March 2024 the average cost of delivering the GBIS obligation was around £27.27 per £ annual bill savings, up from £25.15 to the end of December 2023.
The next update to the quarterly GBIS costs data will be in the 19 September 2024 release.
