DGN GAS designs and installs air source heat pumps across Chalfont St Giles. System design, commissioning and MCS certification are handled through our accredited partner, so your installation qualifies for the £7,500 government grant. Free no-obligation assessments.
Chalfont St Giles is genuinely strong heat pump territory. Many of the village's larger homes aren't on mains gas at all — they run on oil or LPG — which is exactly where a heat pump wins hardest. DGN GAS installs air source heat pumps across the Chalfonts, 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.
In a village like Chalfont St Giles, a good number of the larger and characterful homes are off the mains gas grid, running on oil or LPG. Those are the properties where a heat pump genuinely shines — on both running cost and grant eligibility. Space is rarely the issue out here; the work is in designing the system carefully around an older or period property so it performs.
We cover Chalfont St Giles including the village, Chalfont St Peter, Little Chalfont, Jordans and Seer Green — for heat pump design, installation, cylinders and underfloor heating.

Many Chalfont St Giles homes run on oil or LPG, which can make them eligible for a higher Boiler Upgrade Scheme grant than the standard £7,500 when switching to an air source heat pump — plus 0% VAT on the installation. The grant is applied as a discount on your quote.
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 Chalfont St Giles quote from the start.
