Government Backing and Timeline (From March 2023, budget £1 billion, till March 2026)
The Great British Insulation Scheme (GBIS) is one of the UK government’s flagship programs designed to help households cut energy costs and make homes more energy-efficient. Launched in March 2023 with a budget of £1 billion, the scheme is scheduled to run until March 2026.
The latest statistics published in May 2025 provide fresh insights into how GBIS is progressing across England, Scotland, and Wales. For homeowners and tenants, these updates are a clear reminder: now is the time to check eligibility and take advantage of insulation grants.
At Reliant Energy Solutions, we help households apply for GBIS funding, arrange free surveys, and install insulation measures with accredited professionals.
Key Statistics from May 2025
The Great British Insulation Scheme is overseen by the UK Department for Energy Security and Net Zero (DESNZ), working alongside Ofgem and local councils. This ensures that funding is delivered transparently and households across England, Scotland, and Wales can access the right type of insulation support based on need. According to Ofgem data, here’s the latest delivery snapshot:
- 76,900 insulation measures installed in 60,600 households since launch.
- 6,500 measures delivered in March 2025 alone – a 14% increase compared to February.
- Monthly delivery average (Jan–Mar 2025): 5,900 measures, slightly down compared to late 2024.
- 38,200 measures (50%) went to low-income households, including 5,100 through Local Authority Flexible Eligibility (LA Flex).
- 5,600 innovation measures installed, mainly in low-income groups and social housing.

What Types of Insulation Are Most Common?
The statistics show which insulation methods are most popular under GBIS:
- Cavity wall insulation – 31,500 measures (41%)
- Loft insulation – 21,400 measures (28%)
- Heating controls – 16,300 measures (21%)
- Solid wall insulation and other measures make up the rest.
These upgrades not only improve home comfort but also increase property value and reduce carbon emissions.
Regional Breakdown of Installations
GBIS uptake varies significantly across the UK:
- North West: 16% of all measures
- West Midlands: 15%
- North East: 12%
- Wales: Highest household upgrade rate – 271 per 100,000 households
- England: 222 per 100,000
- Scotland: 140 per 100,000
Local authorities leading the way include:
- West Lindsey – 1,674 households upgraded per 100,000
- Stoke-on-Trent – 1,361 per 100,000
- Salford – 1,042 per 100,000
These figures highlight that uptake is not uniform – and many regions still have households missing out.
Who Is Eligible?
GBIS targets two main groups:
- Low-Income Households – similar to the ECO4 Help to Heat group.
- General Eligibility Group – broader criteria for homes with poor energy efficiency.
Local councils can use LA Flex to refer vulnerable households based on:
- Low income
- Fuel poverty
- Health conditions aggravated by cold (e.g. asthma, arthritis, cardiovascular disease)
This means even if you’re not on benefits, you may still qualify.
