Heat Pump Installation in Crawley: What You Need to Know
Electromatic M&E Ltd covers Crawley (RH10/RH11) for air source heat pump and solar PV installations, and this planned new town’s combination of post-war housing estates, newer residential developments, and excellent solar irradiance makes it a strong market for renewable energy systems. The £7,500 BUS Grant — subject to eligibility — is available to eligible homeowners as part of our standard service, approximately 30 miles from our Sunbury-on-Thames base. 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.
Crawley was developed from the late 1940s as one of the South East’s designated new towns, which means its housing stock has a different character from the Victorian and Edwardian terraces that dominate much of London and Surrey. The post-war design principles emphasised well-insulated homes with gardens — a profile that suits heat pump installation particularly well — alongside newer developments built to more recent energy standards.
Is Your Crawley Home Suitable for a Heat Pump?
Crawley’s housing stock is among the most practically suited to heat pump installation in the South East. The planned new town design resulted in semi-detached and detached houses with good cavity walls, rear gardens, and simple roof forms — all of which support straightforward ASHP installation and solar PV. Nesta research (2023) found that 80–90% of UK homes already have adequate insulation for effective heat pump operation, and Crawley’s post-war housing with cavity walls often meets this standard without additional preparatory works.
Newer developments in RH10 and RH11 — those built post-2000 in areas like Forge Wood, Maidenbower, and Pound Hill — are well insulated by design and are frequently ASHP-compatible without any radiator upgrades. These properties are often the easiest and most cost-effective to survey and install.
The original post-war neighbourhood housing — in estates like Langley Green, Gossops Green, and Bewbush — has cavity walls that may have been filled and good garden access. The straightforward low-pitched roof design also tends to support solar PV well, particularly on south-facing slopes. Shading from mature trees on some of the established estate roads is worth checking during the survey.
Crawley benefits from a more southerly latitude than many of the London areas we cover, which improves solar yield slightly. A 4kW solar system in RH10 or RH11 generates approximately 3,500–3,800 kWh per year based on PVGIS data, making the solar economics particularly strong.
Crawley Property Types at a Glance
| Property Type | Heat Pump Suitability | Solar PV Suitability | Notes |
|---|---|---|---|
| Post-war semi-detached (1950s–70s) | High | High | Cavity walls; good garden access; straightforward |
| New build (post-2000) | Very High | High | Excellent insulation; often ASHP-ready |
| Post-war detached | High | High | Good space; strong solar potential |
| 1990s estate housing | High | High | Well insulated; standard permitted development |
| Flat (estate block) | Low | Low–Medium | ASHP usually unsuitable; solar depends on ownership |

Planning Permission in Crawley
Most Crawley properties qualify for permitted development rights for ASHP installation, and the planned new town character means conservation area restrictions are minimal across the vast majority of residential streets. The General Permitted Development Order (Class G) allows a single ASHP unit at residential properties without a planning application, provided the unit does not face the highway and meets MIS 3005 noise standards.
Crawley Borough Council applies standard planning policies for ASHP installation. The Crawley town centre area and some older character buildings may warrant an individual planning check, but for the overwhelming majority of post-war and newer housing in RH10 and RH11, permitted development applies straightforwardly. We confirm the planning position for every property during the free survey.
The BUS Grant in Crawley: How to Claim £7,500
Your Crawley 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 as part of every ASHP installation — you do not need to apply yourself.
For RH10 and RH11 properties, meeting the EPC eligibility condition is typically straightforward. Post-war housing often already has cavity wall insulation and good loft insulation. For older estate properties where insulation may not have been updated, improving loft insulation to 270mm is an inexpensive preparatory step. New builds built post-2000 typically meet the EPC condition without any additional works.

ASHP + Solar: The Crawley Combo
Crawley is one of the better locations in our service area for solar PV, thanks to its more southerly position and the prevalence of housing with good roof exposure. A 4kW south-facing solar system in RH10 or RH11 generates approximately 3,500–3,800 kWh per year based on PVGIS data — slightly above the London average — directly offsetting heat pump electricity costs. At April 2026 electricity prices of 24.5p/kWh, this represents meaningful annual savings.
The Energy Saving Trust estimates that a combined ASHP and solar system reduces annual energy bills by £600–900 compared to a gas boiler. For newer Crawley properties with already-good insulation, the heat pump’s seasonal performance factor is likely to be high, further improving the economics. Battery storage is an optional add-on that allows solar generated during the day to power the evening heating cycle — a particularly good fit for Crawley family homes where evening occupancy is the norm.

Heat Pump Running Costs in Crawley
| Heating System | Annual Running Cost* | CO₂ per Year |
|---|---|---|
| Gas boiler (new) | £1,100–1,400 | 2.4–3.0 tonnes |

Frequently Asked Questions — Heat Pumps in Crawley
How much does a heat pump cost in Crawley?
A typical air source heat pump in Crawley costs £10,000–14,000 before the BUS Grant. After the £7,500 government grant (subject to eligibility), most RH10/RH11 homeowners pay £5,000–7,500 all-in for a full ASHP installation including labour, materials, and commissioning.
Are Crawley’s post-war homes suitable for heat pumps?
Yes — Crawley’s post-war planned town housing stock is among the most practically suited to ASHP installation in the region. Cavity walls, good garden access, and straightforward planning conditions all support quick and cost-effective installations. Newer properties built after 2000 are particularly strong candidates. We confirm suitability during the free survey.
Is planning permission needed for a heat pump in Crawley?
In most of Crawley, heat pump installation falls under permitted development rights — no planning application is needed. The planned new town character means conservation restrictions are minimal. We confirm the planning position during the free survey.
How long does installation take in Crawley?
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. Solar panel installation adds a further day.
Can I get a combined heat pump and solar panels in Crawley?
Yes — Crawley’s housing stock, particularly newer developments, is well suited to combined ASHP and solar systems. The more southerly location improves solar yield slightly compared to London. Electromatic installs both as a single package from one contractor. 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.
