Heat Pump Installation in Sidcup: What You Need to Know
Electromatic M&E Ltd covers Sidcup and the DA14/DA15 area for air source heat pump and solar PV installation. Sidcup is a well-established suburban area in the London Borough of Bexley with a predominantly 1930s housing stock — semi-detached and detached houses that are among the most ASHP-friendly property types in Greater London. 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). Sidcup’s well-maintained 1930s residential streets provide some of the most straightforward conditions for heat pump installation in outer South-East London.
Is Your Sidcup Home Suitable for a Heat Pump?
The 1930s semi-detached and detached houses that characterise the majority of Sidcup’s residential streets are well-suited to heat pump retrofitting. These properties were built with cavity wall construction, have good loft dimensions for insulation, and typically feature gardens of a size that easily accommodates an ASHP external unit. Many have also been improved over the years with cavity wall insulation already in place.
Solar PV is particularly attractive in Sidcup. Properties in DA14 and DA15 benefit from reasonable solar irradiance, and south- or south-west-facing roof slopes on the area’s semis and detacheds can deliver consistent generation over the year. A combined ASHP and solar project is often the most cost-effective approach for Sidcup homeowners.

ASHP + Solar: The Sidcup Combo
Sidcup’s 1930s semis and detacheds are ideally suited to combined ASHP and solar PV projects. A 4kW solar system in DA14/DA15 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 further increases the value of daytime solar generation. Electromatic installs all three elements as a coordinated project from a single contractor.

Are Sidcup’s 1930s semis suitable for heat pumps?
Yes — they are among the most suitable property types for heat pump retrofitting. Good cavity wall construction, adequate gardens, and well-proportioned roofs make them ideal candidates for ASHP and solar PV.
Is planning permission needed for a heat pump in Sidcup?
In most cases, no. ASHP installation qualifies as permitted development for most Sidcup homes. We check the specific 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.
