Consequently, many properties may receive complimentary insulation alongside their free boiler installation.

ECO4 will be a four-year scheme and is intended to run from 1 April 2022 to 31 March 2026. The main objective of ECO4 is to improve the least energy efficient housing occupied by low income and vulnerable households.

Under ECO, medium and larger energy suppliers fund the installation of energy efficiency measures in British households. Each obligated supplier has an overall target based on its share of the domestic energy market in Britain. The obligated energy suppliers work with installers to introduce certain efficiency measures into your homes.

The first step is to check your eligibility. Fill out our eligibility checker to see whether your home qualifies and let us take care of the rest for you!

The ECO4 scheme is the latest version of the governments ongoing initiative to increase energy efficiency in the UK. With several households now in fuel poverty, this scheme is targeted towards lower income households.

This includes internal, external, cavity wall, flat roof, pitched roof insulation. There are also solutions available for underfloor insulation too.

A new A+ grade condensing boiler could save you 20-30% on your energy bills and help to reduce the impact of future price hikes.
