Heat Pump Installation in Bexley: What You Need to Know
Electromatic M&E Ltd covers Bexley and the DA5 area for air source heat pump and solar PV installation. Bexley Village and the surrounding DA5 area offer some of the most attractive residential settings in outer South-East London, with a well-established stock of 1930s semis and larger post-war detached homes. 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). Bexley’s suburban character — with relatively spacious plots, good insulation standards in later-built housing, and manageable planning requirements — makes it well-positioned for heat pump retrofitting.
Is Your Bexley Home Suitable for a Heat Pump?
The 1930s and post-war housing that dominates Bexley’s residential streets is well-suited to heat pump installation. These properties typically feature cavity wall construction, good loft space for insulation, and gardens large enough to accommodate an ASHP external unit with no difficulty. Many have been improved by private owners over recent decades, with insulation already in place.
Bexley Village itself has an older character with some listed buildings and a conservation area designation around the historic High Street. Properties within or adjacent to this area may require additional planning checks, though most ASHP installations can still proceed as permitted development with correct siting. For the majority of DA5 suburban housing, the planning picture is straightforward.

Planning Permission in Bexley
Most DA5 homes qualify for permitted development rights for ASHP installation under Class G of the General Permitted Development Order. The area around Bexley Village has conservation area designations that warrant a pre-installation planning check. Listed buildings require full planning permission for any external equipment. We carry out all necessary planning and conservation area checks during our free home survey.
The BUS Grant in Bexley: How to Claim £7,500

ASHP + Solar: The Bexley Combo
Bexley’s larger suburban properties with south-facing roof slopes are well-suited to combined ASHP and solar PV projects. A 4kW solar system in DA5 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. For Bexley’s larger detached properties, systems of 6–8kW may be achievable, significantly increasing self-generation. Battery storage is a high-value addition, particularly for larger homes with higher evening energy demand.
Heat Pump Running Costs in Bexley
| Heating System | Annual Running Cost* | CO₂ per Year |
