Air source heat pumps in Westhampnett, done properly
Hot water from an air-to-water system is stored in a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. With air-to-air, hot water has to come from something else. The work covers underfloor heating, homes heated by oil, LPG or gas and air-to-water heat pumps, and common reasons people get in touch are checking eligibility for a heat pump grant and no space for a hot water cylinder.
In a place like Westhampnett, some homes are listed, because permitted development does not apply within the grounds of a listed building, so we check consent first.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

What the work involves, system by system
Air-to-air heat pumps
A £2,500 Boiler Upgrade Scheme grant is available for air-to-air only if it replaces the fossil-fuel heating and meets the full heating demand. It must be installed by an MCS certified installer and be in a home.
Air-to-water heat pumps
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. A £7,500 grant may be available through the Boiler Upgrade Scheme for eligible homes and the installer applies.
What air conditioning will not do
Air source heat pumps can’t fix everything, and we’ll tell you before we start. It won’t put right:
- Getting planning permission or listed building consent on your behalf
- A grant for a home that does not meet the scheme rules
- Draught-proofing and insulation upgrades
If you’re not sure, just ring us on 07833 053749 or drop us a line and we’ll give you a straight answer before booking.

Westhampnett questions
Can I get the Boiler Upgrade Scheme grant in Westhampnett?
Yes, the scheme covers homes in England, including Westhampnett, if they qualify. The amount depends on the type of heat pump, and the survey confirms which applies. We hold MCS certification, so the application is ours to make for you.
Do you cover smaller places like Westhampnett?
We do. Villages and hamlets get the same service as the bigger towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Who is responsible for leak checks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Do you look at the job first?
Yes. Photos often do the job for simple work, while bigger systems and repairs that need testing get a visit.
Is a heat pump permitted development?
Under the Planning Portal rules, a heat pump on a house can often be permitted development. Listed buildings are excluded, and listed building consent is separate, so we check for your property.
How soon will you get back to me?
The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
Can you look at a system you didn’t fit?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Tell us the make and model and send any paperwork you have.
Heat pumps in Westhampnett: local notes
About 34% of homes in and around Westhampnett have been built since 2000, according to Valuation Office Agency council tax records. Better insulated, newer homes are often a good match for a heat pump. On the National Heritage List, around 10 entries fall within 0.5 miles of the middle of Westhampnett; The Parish Church of St Peter (grade II*) is one. That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where necessary, we check with the planning team at Chichester council, which normally handles Westhampnett.
Goodwood House, roughly 1.6 miles north, is a reminder to check your home’s listing status: permitted development does not cover listed buildings.

- Questions about where the outdoor unit can go
- Checking eligibility for a heat pump grant
