Heat Pump Installation in Hayes: What You Need to Know
Electromatic M&E Ltd covers Hayes (UB3/UB4), approximately 13 miles from our Sunbury-on-Thames base, installing air source heat pumps and solar PV systems for homeowners across this outer west London area. Hayes combines post-war housing estates, 1930s semis, and a growing number of new-build developments — particularly around the Crossrail/Elizabeth line corridor that has brought significant regeneration to the area. This mix of housing stock is broadly very well suited to heat pump technology. The BUS Grant of £7,500 (subject to eligibility) can make a material difference to the upfront cost, and Electromatic handles the full application process on your behalf.
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).
Is Your Hayes Home Suitable for a Heat Pump?
Hayes’ housing stock is dominated by post-war and interwar properties — both of which are well suited to heat pump technology. The area grew rapidly between the 1920s and 1960s, producing a large number of semi-detached houses on generous plots, many of them now owner-occupied following right-to-buy schemes. More recently, new-build homes and apartment developments around the Hayes & Harlington station area have added to the housing mix.
Post-war semis and terraces in UB3/UB4 typically have cavity walls, accessible loft spaces, and rear garden plots that provide suitable space for an ASHP outdoor unit. According to Nesta (2024), post-war cavity-wall homes with loft insulation achieve heat pump efficiency (COP) of 2.8 to 3.5, making them among the most cost-effective retrofit candidates in the UK.
New-build homes in Hayes — including those developed as part of the regeneration around the Elizabeth line — are built to modern insulation standards and are highly suitable for heat pump operation. Some may already have heat pumps specified as part of the development.
For flat owners, air source heat pumps are generally not appropriate for individual units. Solar panels may be viable on flat roofs of newer blocks subject to management company consent.
Hayes Property Types at a Glance
| Property Type | Heat Pump Suitability | Solar PV Suitability | Notes |
|---|---|---|---|
| Post-war semi-detached | High | High | Cavity wall; good garden; strong ASHP candidate |
| New-build house | Very High | High | Modern insulation; may have ASHP pre-specified |
| 1930s semi-detached | High | High | Good cavity wall potential; generous plot |
| Purpose-built flat | Low | Low–Medium | ASHP not suitable; flat roof solar possible |

Planning Permission in Hayes
Hayes is outside conservation area designations, and most homes in UB3 and UB4 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 face a public highway, and the installation must comply with MIS 3005 noise requirements.
For new-build developments, any external equipment restrictions in the original development planning consent or building management rules should be checked — Electromatic reviews this during the free home survey. For most standard houses in Hayes, ASHP installation proceeds under permitted development without difficulty.
The BUS Grant in Hayes: How to Claim £7,500
Your Hayes 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. Post-war and new-build homes in Hayes are often in a strong position here. Electromatic reviews your EPC at the free home survey and advises on eligibility and any steps needed.
Ofgem administers the grant and pays it directly to the installer. Electromatic handles the full application process on your behalf.

ASHP + Solar: The Hayes Combo
Hayes is well positioned for combined ASHP and solar PV installations. The area’s post-war and new-build homes typically have pitched roofs with favourable solar orientation, and the generous plot sizes provide space for battery storage alongside the outdoor ASHP unit. In UB3/UB4, a 4kW solar system generates approximately 3,400–3,800 kWh per year (PVGIS London irradiance data), offsetting a meaningful share of the heat pump’s electricity consumption.
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. Battery storage is an optional add-on that captures surplus daytime generation for evening use. Electromatic installs ASHP and solar PV as a combined package from a single contractor.
Heat Pump Running Costs in Hayes
| 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.

Frequently Asked Questions — Heat Pumps in Hayes
How much does a heat pump cost in Hayes?
A typical air source heat pump in Hayes costs £10,000–14,000 before the BUS Grant. After the £7,500 government grant (subject to eligibility), most Hayes homeowners pay £5,000–7,500 all-in for a full ASHP installation including labour, materials, and commissioning.
Are Hayes post-war houses suitable for heat pumps?
Yes — they are among the most straightforward heat pump retrofit candidates. Cavity walls, accessible loft spaces, and good garden plots make them ideal. Many are already eligible for the BUS Grant without needing preparatory insulation work.
Is planning permission needed for a heat pump in Hayes?
In most of Hayes, heat pump installation falls under permitted development rights — no planning application is needed. Exceptions apply to listed buildings. We check planning status during your free survey.
How long does installation take in Hayes?
A heat pump installation typically takes 1–2 days for a standard property. Electromatic M&E Ltd usually installs within 2–4 weeks of survey confirmation — significantly faster than most national installers.
Can I get a combined heat pump and solar panels in Hayes?
Yes — and Hayes’ post-war and new-build housing is well suited to the combined system. Electromatic installs ASHP and solar PV as a combined package. A combined ASHP + 4kW solar system typically costs £17,000–19,000 before grants, with the BUS Grant (£7,500, subject to eligibility) reducing the heat pump element significantly.
