What’s the reason for the funding?

Regardless of which funding or grant scheme you apply to, the end goals are much the same;

  • Making your building more energy-efficient
  • Reducing carbon footprint
  • Lowering your bills
  • Improving comfort
  • Improving air quality
  • Future proofing your property

The UK Government is on a big drive to push for net zero carbon emissions by the year 2050, and these grants and schemes are representative of that. The ECO4 scheme alone has $4 billion allocated to it, so get your claims in before these schemes close down for good.

Which grant scheme is right for you?

ECO4

Solar

Central heating

Replace your old gas central heating with an A-rated energy system that will make your building cosy and warm and save you money on your heating bills.

Electric storage heaters

Upgrade your outdated electric storage heaters with modern equivalents that are more aesthetically pleasing, energy-efficient and have enhanced control features.

Boilers

The ECO4 grant has funding available for many different types of boilers, including electric and hydrogen. See if you’re eligible for a grant today!

Insulation

The fastest way for a building to lose heat is if it’s insufficiently insulated. Use the ECO4 grant scheme to apply for funding towards roof insulation, wall insulation, and underfloor insulation and make it up to 40% more energy efficient.

ECO4 Grant
LA Flex

The LA Flex scheme runs in tandem with the ECO4 scheme but is granted by your local council on a case-by-case basis. While there are strict eligibility criteria, you can make your home far more energy-efficient with its grants for insulation, boilers, and solar energy systems.

LA Flex Grant
The Great British Insulation Scheme (GBIS)

The GBIS provides help to the most vulnerable people who don’t qualify for funding from the ECO4 scheme to upgrade their homes. On average, applicants save between £300 and £400 a year on their energy bills with the help of the GBIS, so see if you’re eligible today.
