Boiler Upgrade Scheme

If your home isn’t eligible for a fully funded ECO4 boiler, the Boiler Upgrade Scheme (BUS) offers a government grant towards a new, more efficient heating system – helping you lower installation costs and cut long-term energy bills.

ECO4 Grants – Your Path to Efficient Home Heating at £0

The ECO4 Scheme helps households with EPC ratings E, F, or G replace old, inefficient heating systems with fully funded upgrades. If you receive qualifying benefits, you could get free heating and insulation improvements to cut bills and stay warmer.

Since April 2022, 260,000+ households have benefited from 875,000+ ECO4 measures, part of the 4.3 million measures installed across 2.6 million homes under the Energy Company Obligation.

Get fully funded heating upgrades (boilers, radiators, insulation, or heat pumps) installed by Gas Safe engineers to PAS 2035 standards. Stay warmer and more energy-efficient this winter.

Free Boiler Grant

Replace your old, inefficient boiler with a brand-new A-rated condensing boiler (with up to 94% efficiency) – fully funded under the ECO4 Scheme. Enjoy lower energy bills, reduced carbon emissions, and faster, more reliable heating. Installed by Gas Safe engineers following PAS 2035 standards, this upgrade is completely free for eligible households.

First Time Central Heating Grant

No heating system? No problem. Eligible homes can receive a complete central heating system, including boiler, radiators, pipework, and smart heating controls – fully funded. This grant ensures every room stays warm, hot water is available on demand, and energy is used efficiently. Installation is handled by certified experts, so you get a safe, hassle-free upgrade.

Air Source Heat Pump Grant + Free Solar Panels

Off-gas or fully electric homes can benefit from a modern air source heat pump. They provide low-cost, renewable heating. For eligible households, the system (including free solar panels) is 100% covered by the government. Efficient, eco-friendly, and ideal for long-term savings, these systems reduce electricity costs.

Electric Storage Heater Grant + Free Solar Panels

Homes without a gas connection can get high-heat retention electric storage heaters, perfect for maintaining consistent warmth all day. Eligible households also receive free solar panels, cutting electricity costs and boosting efficiency. The full system installation is fully funded, safe, and handled by certified engineers.

LA Flex Grant

Even if you don’t receive traditional benefits, you may qualify under Local Authority Flexible Eligibility (LA Flex). LA Flex helps low-income households, or those with health conditions worsened by cold, access fully funded boilers, heat pumps, insulation, and central heating upgrades. This is all fully funded by the UK government.

Insulation Grant

Keep heat where it belongs – inside your home. The government covers loft insulation, cavity wall insulation, underfloor and internal wall insulation, all fully funded for eligible households. Better insulation means lower bills, a warmer home, and improved EPC rating – helping you stay cosy while cutting energy waste.

In my opinion they are going after government grants and will be relentless in their pursuit of the money. They installed a boiler and it works fine. I don't expect they'll be any good at follow-up service but I understood this from the outset.

We had boiler replaced with this company and had a great service. Very polite staff and finish their work within the time frame. Highly recommend this company

The people who worked installed a fan in the bathroom,insulation and windows vent on all windows. They are also very helpful and friendly.

very pleasant people who worked hard all day and did a terrific job. They seemed to a always be running as they worked and at the end of the day they explained to us what they had done and gave us a demonstration of how to use the new equipment
