  • 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 – these grants and schemes are proof of that. The government-backed ECO4 scheme alone has $4 billion allocated to it. Get your claims in before these schemes close down for good.

Which grant scheme is right for you?

ECO4

This is the most all-encompassing grant scheme out there at the moment, covering everything from insulation to solar energy installations. Head over to the respective pages of each service to learn if you’re eligible, how much you can apply for, and when funding runs out.

Solar

PV panels, battery storage, and energy inverters. To get a better idea of what kind of solar energy installation you might need for your property (and whether you meet the criteria for funding), just enter a few details into our easy-to-use calculator. It couldn’t be simpler!

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Upgrade your outdated electric storage heaters with modern equivalents that are more aesthetically pleasing, energy-efficient and have enhanced control features.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

I had Alex & Simon at my house. Hands down, they are the best workmen EVER, by miles. They arrive on time, are polite, super clean & tidy in their work & cleaning up afterwards. Spectacularly good work was carried out by them both. They clearly take pride in the quality of work they do & their cleanliness in people’s homes, which is sadly lacking for most trade's people today who just don’t care how shoddy their work is or have no respect for people’s property.

The two surveyor's who came out were very professional and personal, we had a laugh about one being a Wigan warriors fan and we're Rhinos fans lol. Then Rob who came out to fit the boiler again very professional and personal, very tidy workmanship. Can't thank your company enough, new boiler fitted in less than a week and easy to deal with.
