Summary of the Great British Insulation Scheme: July 2024

Published 18 July 2024

Applies to England, Scotland and Wales

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 May 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 15,200 measures installed in 12,200 households up to the end of May 2024.

Measure delivery has continued to increase, with 3,500 measures installed in 2,700 households in May 2024 – the highest level since the scheme began. This is an increase of 58% compared to delivery in April.

The data used in Figure 1 can be found in Table 1 of the Accompanying Tables.

Delivery by measure type

As shown in Figure 2, the most common measure so far has been cavity wall insulation, accounting for 50% (7,500 measures) of the total 15,200 measures. This was followed by loft insulation which accounted for 23% (3,400 measures) and heating controls which accounted for 20% (3,000 measures).

The data used in Figure 2 can be found in Table 3 of the Accompanying Tables.

Delivery by region

As shown in Figure 3, the highest regional delivery has been in the South East (2,200 measures, 14%), followed by Yorkshire and The Humber (2,100 measures, 14%) and the North West (1,800 measures, 12%).

The data used in Figure 3 can be found in the ‘Percentage of total measures installed’ column of Table 4 in the Accompanying Tables.

The regional breakdown of upgraded households is largely the same as the regional breakdown of measures installed, as the majority of households (around 10,600 out of 12,200) have had only one measure installed under the scheme up to the end of May 2024. 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).

There have been 12,200 households upgraded under GBIS up to the end of May 2024, meaning they have had at least one measure installed. This is around 44 households per 100,000 households (based on estimated household levels for 2023). The rates for Wales and England were slightly higher at 48 and 45 per 100,000 households respectively, while Scotland had a rate of 30 per 100,000. The region with the highest rate was Yorkshire and The Humber with an estimated 71 households upgraded per 100,000.

Delivery by local authority area

GBIS measure delivery, upgrades and the estimated rates per 100,000 households in each local authority are provided in Table 5 of the tables accompanying this release. For the first time this month, a map has also been introduced showing the rate of upgrades per 100,000 households in each local authority (Map 1).

The level of delivery under GBIS varies at the local authority level. The local authorities with the highest rate of upgrades under GBIS so far are City of Kingston upon Hull (436 upgrades per 100,000 households), Luton (313 per 100,000) and Isle of Anglesey / Ynys Môn (210 per 100,000).
