Heat Pump Installation in Barnet: What You Need to Know
Electromatic M&E Ltd covers Barnet (EN5), approximately 25 miles from our Sunbury-on-Thames base, installing air source heat pumps and solar PV systems for homeowners in this outer north London suburb. Barnet is characterised by 1930s detached and semi-detached houses on substantial plots — a housing type that consistently delivers the best conditions for heat pump installation. The generous gardens, good insulation potential, and ample roof area typical of EN5 properties make Barnet an excellent area for combined ASHP and solar PV projects. The BUS Grant of £7,500 (subject to eligibility) can make a significant difference to the upfront cost of switching from gas, and Electromatic handles the full application as part of every installation.
According to the Energy Saving Trust, a typical UK semi-detached home switching from a gas boiler to an air source heat pump saves between £300 and £500 per year on heating bills at April 2026 Ofgem price cap rates (electricity 24.5p/kWh, gas 7.4p/kWh). For the larger detached properties common in Barnet, savings are often proportionally greater.
Is Your Barnet Home Suitable for a Heat Pump?
Barnet’s 1930s detached and semi-detached housing stock is among the strongest in outer north London for heat pump installation. Properties across EN5 — from Barnet town centre through East Barnet and New Barnet — typically have cavity walls, generous rear gardens, accessible loft spaces, and well-orientated roof slopes.
1930s detached homes in Barnet represent premium heat pump retrofit candidates. The combination of cavity wall insulation (either installed or available), substantial gardens for outdoor unit placement, and large roof areas for solar PV creates excellent conditions for a whole-home energy upgrade. According to Nesta (2024), 1930s homes with cavity wall and loft insulation achieve heat pump efficiency (COP) of 2.8 to 3.5 — a performance level that makes the running cost case for switching from gas compelling.
Post-war properties in Barnet are similarly well suited, and many have insulation levels that already meet the BUS Grant eligibility requirements.

Planning Permission in Barnet
Most homes in Barnet qualify for permitted development rights for ASHP installation under Class G of the General Permitted Development Order — no formal planning application is required. The standard conditions apply: the outdoor unit must not be placed on a wall or roof facing a public highway, and the installation must comply with MIS 3005 noise requirements. For the detached and semi-detached homes typical of EN5, rear garden placement almost always satisfies these conditions.
Barnet is largely outside conservation area designations that would significantly restrict ASHP installation. The historic town centre area has some local designations, but the majority of residential streets are unaffected. Electromatic checks all planning conditions during the free home survey and advises on any exceptions.
The BUS Grant in Barnet: How to Claim £7,500
Your Barnet 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. Many Barnet homes — particularly where insulation has been installed — are already in a strong position for grant eligibility. Electromatic reviews your EPC during the free home survey and advises clearly on next steps.
Ofgem administers the BUS Grant and pays it directly to the installer. Electromatic handles the full application process on your behalf.

ASHP + Solar: The Barnet Combo
Barnet is an excellent area for combined ASHP and solar PV installations. The area’s 1930s detached and semi-detached homes typically have large pitched roofs with good solar orientation and generous gardens for outdoor unit and battery storage placement. In EN5, a 4kW solar system generates approximately 3,400–3,800 kWh per year (PVGIS London irradiance data), offsetting a significant proportion of the heat pump’s electricity consumption during daylight hours.
Energy Saving Trust data shows that households combining ASHP with solar PV typically save between £600 and £900 per year on energy bills compared to a gas boiler and grid electricity. For Barnet’s larger detached properties, battery storage is an attractive add-on that captures surplus daytime solar generation for evening heating demand, further reducing grid electricity costs.
Heat Pump Running Costs in Barnet
| Heating System | Annual Running Cost* | CO₂ per Year |
|---|---|---|
| Gas boiler (new) | £1,100–1,400 | 2.4–3.0 tonnes |
| Air source heat pump | £900–1,200 | 0.6–0.9 tonnes |
| ASHP + Solar PV (4kW) | £500–800 | 0.3–0.5 tonnes |
*Based on Energy Saving Trust typical UK household data, Ofgem April 2026 prices (electricity 24.5p/kWh, gas 7.4p/kWh). Actual costs depend on property size, insulation, and energy usage.

Are Barnet’s 1930s detached homes suitable for heat pumps?
Yes — they are among the best heat pump candidates in outer north London. Large gardens, good insulation potential, and ample roof area for solar PV make them ideal for a comprehensive energy upgrade.
Is planning permission needed for a heat pump in Barnet?
In most of Barnet, heat pump installation falls under permitted development rights — no planning application is needed. Exceptions apply to listed buildings and certain conservation-sensitive areas. We check planning status during your free survey.
