Heat Pump Installation in East Grinstead: What You Need to Know
Electromatic M&E Ltd covers East Grinstead and the RH19 area for air source heat pump and solar PV installation. East Grinstead is a mid-sized West Sussex market town at the Surrey border, approximately 35 miles from our Sunbury-on-Thames base (TW16), with a housing stock of Victorian and 1930s properties in the town centre and a range of post-war and newer housing in the surrounding suburbs. Eligible homeowners may qualify for the Boiler Upgrade Scheme grant of £7,500 towards an ASHP, subject to eligibility.
According to the Energy Saving Trust, a typical UK semi-detached home fitted with an ASHP saves £300–500 per year on heating bills compared to a gas boiler at April 2026 energy prices (electricity 24.5p/kWh, gas 7.4p/kWh). East Grinstead’s mixed housing stock, good garden sizes, and its position in the High Weald makes it a solid area for heat pump and solar PV adoption.
Is Your East Grinstead Home Suitable for a Heat Pump?
East Grinstead’s housing ranges from Victorian terraces in the historic high street area to 1930s semis and modern detached houses in the residential estates on the town’s fringes. The 1930s and post-war semis that are common throughout RH19 are typically the most straightforward for heat pump retrofitting, offering cavity wall insulation potential, adequate garden space, and well-proportioned roof slopes.
Victorian properties in the town centre and older residential streets can be suitable where insulation has been improved and rear access is available for the ASHP unit. East Grinstead’s position at the northern edge of the High Weald AONB means some rural and semi-rural properties nearby are in landscape-sensitive areas, though this does not in itself remove permitted development rights for ASHP installation.

ASHP + Solar: The East Grinstead Combo
East Grinstead’s position in the South East gives it reasonable solar irradiance, and suburban properties with south-facing roof slopes can achieve consistent annual generation. A 4kW solar system in RH19 generates approximately 3,400–3,800 kWh per year (PVGIS data). The Energy Saving Trust estimates combined ASHP and solar savings of £600–900 per year compared to gas. Battery storage is an effective addition, shifting solar generation from day to evening for heat pump use. Electromatic installs ASHP, solar PV, and battery storage as a coordinated project.
Heat Pump Running Costs in East Grinstead

Are East Grinstead’s 1930s and post-war homes suitable for heat pumps?
Yes — both are strong candidates. Good cavity wall construction, adequate gardens, and reasonable solar irradiance make them well-suited to ASHP and solar PV. We assess everything during the free survey.
Is planning permission needed for a heat pump in East Grinstead?
In most cases, no. ASHP installation qualifies as permitted development for most RH19 homes. Town centre conservation area properties may need additional checks. We confirm the position during your free survey.

A standard installation takes 1–2 days on site. Electromatic M&E Ltd usually installs within 2–4 weeks of survey confirmation. Solar panel installation adds approximately one further day.
