Save Big with the Great British Insulation Scheme UK Guide
The Great British Insulation Scheme helps eligible UK households improve insulation at low or no cost, reducing heating bills and making homes warmer and more efficient.
If your home loses heat easily, this scheme could significantly cut your energy costs.
What Is the Great British Insulation Scheme?
The Great British Insulation Scheme (GBIS) is a UK government-backed programme designed to help households install insulation and reduce energy bills.
It focuses on:
-
Making homes easier to heat
-
Cutting energy waste
-
Reducing carbon emissions
The scheme works alongside ECO4 and targets homes with poor energy efficiency.
What Does the Scheme Cover?
The scheme typically supports insulation measures, including:
Loft Insulation
Uninsulated lofts can lose up to 25% of a home’s heat.
Loft insulation is one of the quickest and most effective upgrades.
Cavity Wall Insulation
For homes with cavity walls, insulation fills the gap between walls and reduces heat loss significantly.
Solid Wall Insulation Where Suitable
Homes without cavity walls may qualify for solid wall insulation, which can greatly improve warmth but is assessed carefully due to higher cost.
Who Can Qualify?
Eligibility depends on property type and household circumstances.
You may qualify if:
-
Your home is in Council Tax bands A–D (England)
-
Your property has a low EPC rating
-
You receive certain benefits
-
You qualify through Local Authority Flex (LA Flex)
Both homeowners and private tenants can qualify (landlord consent required for renters).
Eligibility rules vary by area, so checks are essential.
How Much Can You Save?
Savings depend on the measure installed and the home’s condition, but insulation can:
-
Reduce heating bills by £100–£300+ per year
-
Improve comfort immediately
-
Make heating systems work more efficiently
Savings increase as energy prices rise.
How to Apply for the Scheme
-
Check eligibility with an approved installer or local authority
-
Home assessment to identify suitable insulation measures
-
Approval and funding confirmation
-
Professional installation by an accredited contractor
If approved, work is usually fully or heavily funded.
Why Apply for the Great British Insulation Scheme?
Lower Energy Bills
Better insulation means less heat loss and lower heating costs.
Warmer, More Comfortable Home
Fewer draughts and more consistent temperatures.
Increased Property Appeal
Energy-efficient homes are more attractive to buyers and tenants.
Reduced Carbon Footprint
Lower energy use means fewer emissions.
What the Scheme Does Not Cover
To be clear:
-
It does not fund solar panels
-
It does not cover cosmetic upgrades
-
Measures are chosen based on energy-saving impact
The goal is bill reduction, not home renovation.
Is the Scheme Worth Applying For?
Yes if you qualify.
Insulation is one of the fastest ways to reduce energy bills, and GBIS removes the biggest barrier: upfront cost.
Final Verdict
The Great British Insulation Scheme is one of the most practical ways for eligible households to cut energy bills without spending money upfront.
If your home feels cold or expensive to heat, it’s well worth checking eligibility.
Key Takeaway
The cheapest heat is the heat you don’t lose
and this scheme helps you keep it inside your home.
