Air source heat pumps in
Harrow
Harrow is one of the better-suited parts of our patch for heat pumps. Its 1930s-to-1960s semis and detached family homes generally have the garden space an outdoor unit needs and the room to size radiators correctly or add underfloor heating in an extension. DGN GAS installs air source heat pumps across Harrow, with the design, commissioning and MCS certification handled through our accredited partner.
From luxury homes and high-end renovations to established family houses — every installation is carried out to the same uncompromising standard.
Family homes built for
heat pumps
The classic Harrow family home — a 1930s or post-war semi or detached house with a garden — is close to ideal for an air source heat pump. There's usually room outside for the unit, and scope to upsize emitters or add underfloor heating during a renovation so the system runs efficiently at lower flow temperatures. Replacing an ageing gas boiler also makes these homes eligible for the £7,500 grant.
We cover Harrow including Harrow on the Hill, North Harrow, West Harrow, Harrow Weald, Wealdstone, Pinner, Hatch End and Rayners Lane — for heat pump design, installation, cylinders and underfloor heating.

Which parts of Harrow do you cover?
Why heat pumps make sense here — Ravinder Singh, founder of DGN GAS:
"Harrow is one of the better-suited parts of our patch for heat pumps. The 1930s-to-60s semis and detached homes here usually have the garden space for an outdoor unit and the room to upsize radiators or add underfloor heating in an extension, which is what makes a heat pump actually perform. If you're already weighing up replacing an ageing boiler, it's worth a proper look before defaulting to like-for-like."
Government funding for
Harrow homes
The Boiler Upgrade Scheme gives eligible Harrow homeowners up to £7,500 towards an air source heat pump when replacing a gas boiler, plus 0% VAT on the installation. The grant is applied as a discount on your quote — you don't pay it upfront and claim it back.
Because the application is installer-led and requires MCS certification, the route only works through an accredited installer. We handle that side through our partner, so the funding is built into your Harrow quote from the start.
