Introducing the ECO4 scheme and energy efficiency funding

The Energy Company Obligation is a government scheme aimed at subsidising, or fully funding boiler replacements for qualified homeowners to reduce energy consumption. Many of our customers qualify for a 100% free boiler, and even if you don’t, you could still save up to £800-900 on the cost of a new one. Simply fill out an application, a member of our team will get in touch, and with the help of your local registered engineers, the installation process will begin. Contact us to see if you qualify.

“As the other reviewers have said: Excellent. Straight forward to work with, turned up on schedule, did the work and sent through the guarantees a couple of days later. I can't really fault them!”

  • Are the boilers actually free?
    The grant is free, but you might have to pay a small amount of the total cost of the new boiler. Don't worry, this cost is very miniscule compared to the actual cost of a new boiler.
  • Do I get to choose which type of boiler I want?
    Not directly, no. There are a variety of makes of boilers included in this grant. What happens usually is that the boiler currently installed in your home gets replaced by the same make. We will give you the boiler best suited for your property.
  • Do I qualify for a boiler grant?
    You will qualify if: · You’re a homeowner · Your boiler is either broken or at least 7 years old · You receive at least one benefit from the government
  • Is the free boiler scheme still valid?
    Yes it is! Apply today to check your eligibility and to book yourself a free boiler replacement or any other of our insulation services.
