Affordable heating solutions UK can make a real difference when energy bills are rising and budgets are tight. If you’re on a low income or an elderly homeowner, you could qualify for support that gives you a free boiler or a heat pump to keep your home cosy. In this guide you’ll learn about the main schemes, how to check your eligibility, and the steps to get started.
Explore support schemes
Several options exist to help you warm your home without breaking the bank. The most familiar is the government’s ECO4 grant. It tackles fuel poverty and funds energy efficiency measures (Ecowise Installations). You might also find local authority or charity schemes in your area.
- ECO4 grant: funding for boiler swaps, heat pumps, and insulation
- Free boiler replacement scheme for qualifying households
- Council or charity grants for renewable heaters and loft insulation
Check your eligibility
Before you apply, make sure you meet the basic criteria. Schemes usually look at your income and your home’s current energy rating.
- Income threshold: your household income must fall below a set limit based on size and location (Ecowise Installations)
- Property type: you need a residential dwelling such as a house, bungalow, or flat
- EPC rating: homes rated D or below often qualify for the biggest support (Ecowise Installations)
Get a free boiler
If your boiler is old or inefficient, you could get a new A-rated model at no cost.
- Scheme overview: eligible homes can swap boilers under the ECO4 grant
- Installation: an authorised installer will fit it free of charge
- Savings: newer boilers can cut fuel bills by up to 30 percent
Apply for heat pump grants
Heat pumps are a low-carbon alternative to gas boilers, and they’re free if you qualify.
- Air source and ground source heat pumps are both covered
- Grants can cover 100 percent of the installation cost under ECO4
