The number of insulation measures installed under the Great British Insulation Scheme increased in February, according to new figures. The highest proportion of measures installed was seen in the north east, Polimapper’s visualisation shows.
The Great British Insulation Scheme (GBIS) is a government scheme which provides support in home insulation to foster higher energy efficiency and decrease household energy bills. The scheme targets two eligibility groups: low-income households and a general eligibility group which is measured through council tax classifications.
Statistics from the Department for Energy Security & Net Zero reveal that since the start of GBIS, April 2023, there have been 70.3k measures installed. Measures installed refer to the number of energy efficiency insulation installations.
In February 2025, over 5k installations took place, an increase of 3% in delivery compared to the previous month.
The most common measure to be installed to date has been cavity wall insulation, at 41% of the total measures. This was followed by loft insulation, at 28%.
Polimapper has visualised Great British Insulation Scheme data to show geographical trends.
The highest rate of GBIS measures installed per 100k people was in Leicester East, at 1,747 measures. This was followed by Gainsborough (1,719) and Redcar (1,638). Conversely, GBIS installations were lowest in Hammersmith and Chiswick (10), Hornsey and Friern Barnet (12), and Streatham and Croydon North (13). Explore statistics in your area below.

Geodata context
The new data on the Great British Insulation Scheme comes as councils receive government funds to improve household energy efficiency within their areas.
Commenting on a £3.26m award received by Tanbridge Council from government to improve energy efficiency, Jeremy Pursehouse, chairman of Tanbridge District Council’s housing committee, said: [The funding] means we can make council homes warmer, energy efficient and cheaper to run.”
“It’s a big step in tackling fuel poverty and supporting our tenants during a time when energy costs remain high.”
Commenting on funding received from government’s new Warm Homes: Local Grant Scheme, Judith Hedgley, head of public protection at Middlesbrough Council said: “The Warm Homes scheme will enable improvements to be made to privately owned properties, which includes home owners and landlords, that have lower energy efficiency standards and occupied by households with low incomes.
“The Public Protection Service provides support to tenants and landlords to achieve improvements in the private rented sector, ensuring that dwellings are safe and provide a reasonable standard of comfort, and comply with minimum energy efficient standards.”
Councillor Janet Thompson, executive member for neighbourhoods at Middlesbrough Council: “Energy funding being provided for residents could be life changing in improving home comfort, reducing energy costs and in helping tackle climate change across the Tees Valley.”
