Boiler Upgrade Scheme

See whether the current £7,500 Boiler Upgrade Scheme could help with your heat-pump project.

The Boiler Upgrade Scheme can reduce the upfront cost of an eligible heat-pump installation. HEG uses the current scheme rules as part of a wider survey conversation, checking the property, existing heating, radiator output and proposed heat-pump design before any grant application is progressed.

A heat-pump conversation can include current grant pathways.

The Boiler Upgrade Scheme and Warm Homes routes have different rules. HEG can explain how a heating design fits the process, but neither route is guaranteed until eligibility is confirmed.

Clear information before you decide what happens next.

01

Who the scheme is for

The current HEG source explains that ownership, property location, existing heating, EPC status and installer requirements all matter. Official rules always decide the final outcome.

02

Replace eligible existing heating

The scheme can be relevant when replacing gas, oil, LPG or electric heating, subject to the current official requirements and a suitable proposed design.

03

HEG manages the practical journey

From heat-loss conversation and radiator checks to the installation process, HEG can explain the documentation and steps that apply to your project.

A simple path from a useful starting point to a proper survey.

1

Start with your home

Use the Heat Pump Tool for a useful starting point, then let the survey investigate the technical details.

2

Check the current scheme

Eligibility and grant availability must be confirmed against the live GOV.UK rules, not assumed from an online package.

3

Design the whole system

Heat loss, hot water, radiator output, location, pipework and controls are considered together.

Grant guidance can change—use the official source alongside HEG’s practical help.

The £7,500 contribution, eligibility and application process are subject to live government rules and are confirmed before HEG progresses an application.

“Home Energy Group Ltd is the best. They went above and beyond to help me. A previous company botched fitted a VP panels and Battery Inverter system — Home Energy Group Ltd are the only company who willingly rectified all the previous installation ensuring everything was correct and safe. I will always recommend them.”

“Called quite a few companies re installing a battery storage system. Most were quite pushy. When I called HEG, I was given good, easy to understand helpful information. They answer the phone promptly and are always helpful. The two electricians that installed the system have done a good job and left the house clean.”

“They are clearly a quality business. I found the prices to be reasonable. They are easy to contact on the phone — we don't get that much these days! The engineer turned up on the planned day. He was really good and clearly cared about his work. I would fully recommend them.”
