FREE CAVITY WALL INSULATION in WALES
Reducing Carbon Footprints across Wales
VERY IMPORTANT NOTICE
THE EXISTING GOVERNMENT GRANT SCHEMES ARE COMING TO AN END.
Chancellor Rachel Reeves announced the partial removal of green levies from household energy bills in her Autumn Budget speech on November 26, 2025. This will take effect from 6th April 2026. The green levy is the vehicle that funds the ECO and GBIS grant schemes.
However, because of the time that it takes to carryout surveys, install the work and installers to receive funds, no new applications will be accepted after 24th February. This applies to ECO4 and The Great British Insulation Scheme (GBIS).
We do not know what, if anything, will replace the existing scheme.
Ed Miliband’s (Secretary of State for Energy Security and Net Zero) flagship energy efficiency policy, which has seen its total investment increased to nearly £15 billion. Exact details have not yet been announced. We should hear more in February 2026. This is what we know so far:
- Solar & Heat Pump Grants: The government is set to allocate roughly £13 billion over the next four years for new grants specifically for solar panels, battery storage, and heat pumps.
- Targeted Support: While official eligibility details are still being finalised, the scheme aims to help millions of homeowners, with the most significant assistance for upfront costs directed toward lower-income households and social housing.
- Low-Cost Loans: In addition to direct grants, a new system of low-cost loans is expected to be launched, allowing homeowners to install green technology with no upfront costs and repaying through their energy bills over 5–10 years.
- Heat Pump Grant Extension: The existing £7,500 grants for heat pump installations will remain in place at least until the next general election.
If you are interested in having Solar Panels and an Air Source Heat Pump, please complete our enquiry form and choose the Solar Panels & Heat Pump option.
However, there is still plenty of time for yet another U-turn – watch this space.
FREE CAVITY WALL INSULATION
Breaking News!
Every customer who has cavity wall insulation installed during November or December will receive a £50 thank you!
Free Cavity Wall Insulation is still available in Wales.
It’s free in Cardiff, Swansea, Newport, Carmarthen, Gwynedd, Powys, Ceredigion and throughout Wales using the Great British Insulation Scheme.
The Great British Insulation Scheme (GBIS) is a very simple insulation grant scheme, and you don’t need to be on benefits, and there is no income threshold.
There are 2 routes to qualification.
- Is your council tax band an A, B, C, D or E, and your EPC (Energy Performance Certificate) is a D, E, F or G? Yes – you qualify. Don’t panic if your property does not have an EPC. We will sort that out when we survey your property.
- Are you in receipt of a qualifying benefit? Yes – you qualify.
You can check your council tax banding using this link.
We would also be pleased to supply a quote for Cavity Wall Insulation for those who do not qualify for a Government Cavity Wall Insulation Grant.

ECO4, a new “whole house approach” grant scheme
Under the ECO4 grant scheme, you could qualify for tens of thousands of pounds of energy efficiency improvements – including cavity wall and solid wall insulation, an Air Source Heat Pump and solar panels.
You can learn more about ECO4 here.
LOFT INSULATION under the Great British Insulation scheme.
As of 15/5/25, you can get both free cavity wall insulation and free loft insulation together.
Loft Insulation is by far the biggest loser under the new Great British Insulation scheme.
For most homes, the Government Loft Insulation Grant will not cover the full cost.
However, from 15th May 2025, Loft Insulation became a “secondary measure” and will be able to be installed with Cavity Wall Insulation. This will then cover the full cost of both.
