Available Grants in Belfast City

Residents in the Belfast City Council area can access several government-funded energy efficiency schemes. Here's what's currently available:

ECO4 Scheme

The Energy Company Obligation (ECO4) provides 100% free energy improvements to households receiving qualifying benefits. Measures include loft insulation, cavity wall insulation, solid wall insulation, boiler replacements, solar panels, and air source heat pumps. Your property needs an EPC rating of D, E, F, or G.

Great British Insulation Scheme (GBIS)

The GBIS provides free or heavily subsidised insulation to properties in council tax bands A-D (England). No means test is required — eligibility is based on your property, not your income.

Boiler Upgrade Scheme (BUS)

The Boiler Upgrade Scheme offers £7,500 towards an air source heat pump or £5,000 towards a ground source heat pump. Available to all homeowners in England and Wales with a valid EPC certificate.

Warm Home Discount

A £150 discount on your electricity bill each winter. Most eligible households receive this automatically.

LA Flex Eligibility — Belfast City

Even if you don't receive qualifying benefits, you may still qualify for ECO4 through the Local Authority Flexible Eligibility (LA Flex) route. Each council sets its own criteria.

Belfast City Council — LA Flex

Northern Ireland operates separate energy efficiency schemes. The Northern Ireland Sustainable Energy Programme (NISEP) and Affordable Warmth Scheme provide similar support to ECO4.
