There are various government-backed schemes and grants that may help eligible households with the cost of replacing an old boiler. Eligibility criteria vary and schemes change regularly. This guide gives an overview of the main types of support available.
The Boiler Upgrade Scheme offers grants toward the cost of replacing a gas boiler with a heat pump or biomass boiler. It is aimed at homeowners looking to transition to low-carbon heating, not like-for-like gas boiler replacements. Check current government guidance for the latest grant amounts and eligibility.
The Energy Company Obligation (ECO4) scheme requires energy suppliers to fund energy efficiency improvements for lower-income and vulnerable households. It may cover boiler replacements for eligible households. Eligibility is based on income, benefits, and property EPC rating.
Some local councils run their own boiler replacement or heating improvement schemes. Availability varies significantly by region. Your local council website is the best source for current local schemes.
