5 HeatBoost radiators · subject to survey and grant eligibility
Published prices assume the current £7,500 Boiler Upgrade Scheme contribution where eligible. Final price depends on property survey, heat-loss calculation, eligibility, radiator count, pipework and installation scope.
A clearer conversation about costs
Start with a transparent package, then design for your actual home.
The package shelf gives a useful published starting point. HEG then checks the property, heat loss, radiator output, hot-water requirements, grant pathway and installation scope before confirming a final proposal.
Running costs and comfort depend on the finished design, property performance, heating habits and electricity tariff. HEG does not use generic savings promises.
A thoughtful design considers the heat source and how each room releases heat. HeatBoost radiators are a fan-assisted low-temperature option HEG can consider alongside Harnitek heat pumps.
Low-temperature focus
Room-by-room output is checked against the planned flow temperature.
Made for real homes
The survey looks at insulation, layouts, hot water and outdoor placement.
Connected handover
Published packages include GreenLinx monitoring and clear installation paperwork.
Clearer scope
HEG confirms design, certification and any radiator work before the final agreement.
See the pieces of a thoughtful home-heating conversation.
Good heat-pump design connects the outdoor unit, indoor emitters, property fabric, controls and a clear handover.
Understand the system first
A useful heat-pump conversation begins with how a system moves heat and how your home releases it.
Match emitters to each room
HEG checks radiator output, planned flow temperature, pipework and the rooms that matter most.
Install and hand over clearly
The final system includes a practical handover, paperwork and GreenLinx monitoring where included.
A domestic installation with care
The survey shapes equipment position, pipe routes, room work and the practical plan for your own property.
What happens next

Grant and eligibility
We will help you understand the Boiler Upgrade Scheme route.
The current £7,500 contribution can make a material difference to an eligible project. It is not guaranteed: HEG checks the relevant property, heating and scheme details before the final package is agreed.
The conversation starts with your home—not a generic promise.
Clear starting prices, a transparent grant assumption and a proper survey before a final design.
Heat-pump questions
Helpful answers before you decide.
Could a heat pump suit my home?
Many homes can be considered. HEG confirms insulation, heat loss, radiator output, outdoor location, hot-water requirements and electrical supply through a proper survey and design.
What do the published package prices include?
The published starting packages combine a Harnitek unit, Lux AC controller, five HeatBoost radiators, installation and the listed commissioning, certification, monitoring and guarantee items. Final scope is confirmed by survey.
How does the £7,500 Boiler Upgrade Scheme work?
The grant is subject to scheme rules and eligibility. HEG can discuss the process and confirm whether the proposed project can use the current contribution before finalising the installation price.
Will I need new radiators?
A heat-loss and radiator-output check is essential. HeatBoost radiators can be considered where a low-temperature, fan-assisted option is appropriate, but the final quantity and locations are survey-led.

“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.”
