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.
However, because of the time that it takes to carryout surveys, install the work and installers to receive funds, no new applications will be taken on after 24th February.
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.
However, there is still plenty of time for yet another U-turn – watch this space.

Government ECO Grants in Cardiff and throughout the CF postcode.
There are currently 2 Government ECO grant schemes in Cardiff.
The Government ECO grants in Cardiff are
ECO4. This ECO grant scheme is totally different to all of the previous ECO grant schemes. This is a “Whole House” grant scheme. It includes insulation, heating and renewables. Therefore, it’s really a game changer with £30,000+ grants being spent on homes to improve their energy efficiency and to reduce their Carbon Footprint. However, both the applicant and the property will need to qualify.

The Great British Insulation Grant Scheme in Cardiff (GBIS). The Great British Insulation Scheme (GBIS) is a single insulation scheme. It covers Cavity Wall Insulation, Loft Insulation, Internal Wall Insulation and all the other insulations.
However, loft insulation is available with Cavity Wall Insulation as a secondary measure. The amount of the grant depends on
- The type of insulation. External wall insulation is 10x the cost of cavity wall insulation.
- The floor area of the property. The bigger the better!
- Your Energy Performance Certificate (EPC) rating on the day of the survey. The lower the better. If your property doesn’t have an EPC, don’t panic; we will sort that out when we survey your property.
- Your council tax banding.
Because of the way the grant is calculated, it may not always cover the full cost of the work. However, Cavity Wall Insulation will always be free, and so will loft insulation if being installed with cavity wall insulation. There are no Income thresholds, and Government Benefits are not required.
