With millions of UK homeowners suffering from the high energy prices and freezing homes, watching their bills getting higher and taking more of their hard earned money as a result of inefficient heating systems, the government’s ECO4 initiative might just be your ticket to a warmer, more affordable future. In this blog, we will explore how to receive thousands of pounds in free heating upgrades and why now is the best time to have it done.
Boiler replacement with the ECO4 scheme has direct and immediate financial savings. The new A-rated condensing boilers are over 90% efficient, with the older models being just around 60-70% efficient. This big difference results in huge savings, especially on the long-term over the heating system’s life-span.
Direct Reductions in Bills
Maximum saving can be achieved by replacing the inefficient old boilers. British Gas statistics show that swapping an inefficient old D-rated boiler (78-82% efficient) for a new A-rated boiler could save households up to £600 a year in detached houses, especially when done alondside other measures such as insulation, which is also installed for free under the ECO4 scheme. The ECO4 scheme is based on a whole-house approach that adds to your savings. The government statistics indicate that as of March 2025, ECO4 installations had achieved £138.5 million of estimated yearly bill savings in participating homes. Single households have the potential to save more than 20-30% on energy bills after a new condensing boiler is installed under the scheme.

Extensive Heating Efficiency Measures
Apart from boiler replacement, ECO4 also covers heating controls and smart thermostats, which account for 48% of all ECO4 measures installed. The controls allow more accurate temperature setting and timing, wasting less energy on heating empty rooms and turning the heat off when there is nobody at home. It also allows remote control over heating, giving you the ability to turn it on on your way back from work, increasing comfort and convenience.
For homeowners looking to install air source heat pumps, the cost and environmental benefits are even greater. Changing from a current gas boiler to an air source heat pump has the potential to reduce CO2 emissions by 13.4%, while achieving annual savings of £400-£1,500, based on your house type and current heating system. The ECO4 scheme can help you install solar panels alongside your air source heat pumps, which will usually bring your energy bills dramatically low.
ECO4 programme’s whole-house approach means that most homes can get free insulation in addition to heating measures. Cavity wall insulation saves up to £280 a year, and loft insulation, properly installed, is £135-£250 a year. Together with a low-carbon boiler, they have a huge impact, resulting in peak savings in your bills.
