Heat Pump Installation in Horley: What You Need to Know
Electromatic M&E Ltd covers Horley and the RH6 area for air source heat pump and solar PV installation. Horley is a Surrey commuter town approximately 28 miles from our Sunbury-on-Thames base (TW16), situated just north of Gatwick Airport with a housing stock of 1930s semis and post-war residential housing that is well-suited to heat pump installation. 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). Horley’s predominantly 1930s and post-war suburban housing — with good insulation standards and manageable planning requirements — makes it one of the more straightforward areas in Surrey for heat pump retrofitting.
Is Your Horley Home Suitable for a Heat Pump?
Horley’s housing stock is dominated by 1930s semi-detached and post-war houses throughout the residential streets to the north, east, and west of the town centre. These properties are among the most ASHP-friendly in Surrey: good cavity wall construction, adequate garden space for the external unit, well-proportioned roof slopes for solar PV, and typically good insulation already in place.
Older Victorian properties in the town centre area can be suitable where insulation has been improved and rear access is available. New-build developments on the edges of Horley benefit from modern insulation standards and are typically strong heat pump candidates. The area’s proximity to Gatwick Airport means planning checks for any external installation should confirm no restrictions apply — in practice, most residential RH6 properties are unaffected by aviation planning constraints.

Planning Permission in Horley
Most Horley homes qualify for permitted development rights for ASHP installation under Class G of the General Permitted Development Order. RH6 does not have significant conservation area coverage, making planning straightforward for most residential properties. Standard siting and noise compliance conditions apply. Proximity to Gatwick Airport does not typically affect residential permitted development rights for ASHP installation. We carry out all planning checks during our free home survey.
The BUS Grant in Horley: How to Claim £7,500
Your Horley home may qualify for the Boiler Upgrade Scheme (BUS) grant of £7,500 towards an air source heat pump, subject to eligibility. To qualify, your property must have a valid EPC with no outstanding recommendations for loft or cavity wall insulation. Electromatic handles the BUS Grant application on your behalf as part of every ASHP installation in Horley.

ASHP + Solar: The Horley Combo
Horley’s 1930s semis with south-facing roof slopes benefit from good Surrey solar irradiance. A 4kW solar system in RH6 generates approximately 3,400–3,700 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 shifts daytime solar generation into evening heat pump use. Electromatic installs ASHP, solar PV, and battery storage as a coordinated project — with one contractor managing the full installation.

Yes — they are ideal candidates. Good cavity wall construction, adequate gardens, and well-proportioned roof slopes 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 Horley?
In most cases, no. ASHP installation qualifies as permitted development for most Horley homes. Proximity to Gatwick Airport does not typically affect residential permitted development rights for ASHP. We confirm the position during your free survey.
