Boiler heating still accounts for more than half the average UK home’s energy budget. Many homes are suffering from low efficient heating from their pre-condensing systems that waste up to 40% of the gas being paid for. That means for every pound, only 60 pence is used to warm your home, with 40 pence being wasted. Meanwhile, every new boiler fitted under the ECO4 initiative must be a minimum of 90% efficient.
That improvement translates to more than £400 a year in savings, which is an average of 23% saving on gas bills for a UK home. Newer systems have lower carbon emissions, boosting your home’s value and creating a healthier environment.
Big Savings
Independent tests indicate householders replacing a boiler fitted prior to 2005 can save £300–£580 per year, and that’s without smart controls and insulation upgrades. A detached property of average size is going to deliver about £500 of annual savings once the upgrade is fully installed. Replacing your boiler under the scheme, even if it’s 80% percent efficient, can prove worthwhile, with minimum savings for homes upgrading to their new systems. The best part of this upgrade is that it is completely for free, completely funded under the ECO4 scheme, covering the boiler upgrade as well as any other energy efficiency needs like new or improved insulation and radiators.

Government Schemes That Pay for It
ECO4
The Energy Company Obligation (ECO4) mandates large suppliers to pay for efficiency upgrades in low-income or fuel-poor households. Up to March 2026, boiler replacements, first-time central heating, heat pumps, and insulation can be taken at no cost to the homeowner. ECO Boiler Grants always ensure that all installations meet the rules and regulations of the ECO4 scheme or the initiative that the upgrade is being funded under. All our installations are executed to the highest standards and quality.
Boiler Upgrade Scheme (BUS)
For English and Welsh homes seeking alternatives to gas, the BUS is offering ground-source or air-source heat pumps with £7,500 in funding, with £5,000 being offered for biomass boilers, putting low-carbon technology within a good price range.
Great British Insulation Scheme & Local Grants
If your EPC is below band D, then it is possible to add onto ECO4 council other upgrades, or you can use the Great British Insulation Scheme to package loft and cavity insulation into one job, doubling the savings. ECO Boiler Grants will always try to get the most amount of funding available for you to help secure you for decades to come with a warm and comfortable home.
