Air source heat pumps in West Molesey
In England, an air source heat pump on a house can often go in under permitted development rights. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit can’t be used solely for cooling or sit within the curtilage of a listed building. We check the rules for your property as part of the survey. The work covers radiator systems, underfloor heating and air-to-air heat pumps, and the jobs we see most are working out where a cylinder could go and radiators that may be too small for a heat pump.
Older homes around West Molesey can be draughty or have solid walls, which a heat loss calculation will show. Sometimes insulating first makes more sense.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

Heat pumps in West Molesey: local notes
About 41% of homes across West Molesey and its surrounding area date from 1945 to 1972, according to VOA council tax data. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. There are 2 conservation areas within a mile of the centre of West Molesey. On the National Heritage List, around 4 entries fall within 0.5 miles of the middle of West Molesey; The Vicarage (grade II) is one. For a heat pump, permitted development does not apply within the grounds of a listed building, and in a conservation area the outdoor unit can’t go on a wall or roof facing a road, so we check with the local planning authority (usually Elmbridge council) where needed.
If you live near Hampton station, the survey compares air-to-water and air-to-air for your home before anything is quoted. Hampton Court Palace lies about 1.6 miles east. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.

Owner checks or an engineer?
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Your questions about air source heat pumps in West Molesey
Do you cover smaller places like West Molesey?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
Does the Boiler Upgrade Scheme cover homes in West Molesey?
West Molesey is covered, as the scheme runs across England and Wales. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and isn’t an add-on to a boiler. The installer applies, and we are MCS certified.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Every visit is recorded and F-Gas records kept where they apply.
Do I need planning permission for a heat pump?
Many installations on houses in England fall under permitted development, subject to the rules. Listed buildings are excluded, and listed building consent is separate. We check what applies to you.
What’s the difference between air-to-water and air-to-air heat pumps?
The right choice depends on the property and what you need. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions, and we set out the options after the survey.
Does servicing affect my warranty?
Check the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Keep every service record either way.
Can you look at a system you didn’t fit?
Yes. Systems fitted by other companies are fine, on all the main brands. Send us the make and model, and any records you have.

Looking after your system
Every system needs looking after, and most of it is easy. Our tips:
- Do not block radiators or indoor units with furniture
- Diary the next service
- Avoid switching the heat pump on and off often
If anything does not seem right after installation, phone us on 07833 053749 or email us and we will talk it through. A yearly service is a good habit.
Book a service every year. Check the manufacturer’s terms, as they may include servicing conditions.

Each visit follows the same order: check the plan with you, protect the area, do the work, test what we have done and talk you through it. On site, the work takes from a couple of days to around a week, depending on the system and how much of the heating changes. A few photos let us plan a visit to a place like West Molesey.
