How we handle air source heat pumps in Weston Green
Many air source heat pumps can be installed as permitted development in England, without a planning application. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We look at the planning position for your home during the survey. Typical jobs include moving away from fossil-fuel heating and working out where a cylinder could go, across air-to-air heat pumps, homes heated by oil, LPG or gas and air-to-water heat pumps.
Homes around Weston Green normally have room outside for a heat pump, so the design focuses on heat loss and radiators.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order, and every service is written up.

Air source heat pumps around Weston Green
The Weston Green Conservation Area is within about a third of a mile of the centre of Weston Green. 5 conservation areas lie within a mile of central Weston Green. About 19 listed entries lie within half a mile of central Weston Green, The Old Red House (grade II) among them. Where a home is affected, the outdoor unit position is settled with the planning team at Elmbridge council, which usually handles Weston Green before the heat pump design is finished. About 38% of homes in and around Weston Green were built between the wars, according to VOA council tax data, and about 70% of households live in detached or semi-detached houses, according to Census 2021 figures. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Houses typically have space for an outdoor unit and a hot water cylinder.
Hampton Court Palace, roughly 1.3 miles north, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings. If your home is near Thames Ditton station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits.

What else we do in Weston Green
For landlords and property managers
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We are happy to deal with either side and send the records to whoever needs them.
Running several properties is easier with one contractor. We work across London and the South East, so a run of properties can go into one programme and kept on a regular cycle.
Why deal with it now?
A sudden boiler failure rarely leaves room to plan a heat pump properly. Surveying and designing in advance means the system is sized right and any grant is applied for while the old heating still works. Waiting rarely makes an air conditioning problem smaller.
The cost depends on the system and the number of rooms or units, how easy the units are to reach and the parts and time the job needs. You get a fixed price before work begins, so you know where you stand.
Why people in Weston Green choose us
- Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba and more

Different systems, different jobs
VAT on heat pumps
HMRC says most air conditioning units are air source heat pumps, but each case depends on the facts and the VAT is confirmed on your quote.
Air-to-water heat pumps
An air-to-water heat pump heats water for your radiators or underfloor heating and your hot water cylinder. It replaces the boiler as the main heat source, and is MCS certified when we install it.
Common questions in Weston Green
Is the heat pump grant available in Weston Green?
Yes, if the home and the heat pump meet the scheme’s rules: Weston Green is in England, where it applies. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. As an MCS certified installer, we apply for it on your behalf.
Will you come out to Weston Green?
Yes, smaller places are covered as well as towns. A few photos and the postcode are enough to get things started.
Will you make a mess?
Floors and furniture near the work are covered with dust sheets before work begins, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us in Weston Green and across Surrey. Let us know who the records should go to.
What’s the price of a heat pump installation?
Air-to-water systems are £8,000–£16,000 (0% VAT on homes), before any grant. The final price depends on the heat loss survey, the radiators and the cylinder, and you get a fixed-price quote.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up, with F-Gas records where refrigerant work is involved.
Are you F-Gas certified?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we’re Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
How it works
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we’ve done and answer any questions, and anything that needs attention later is pointed out. All told, the work takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. For a place like Weston Green, the timing is set with you and the travel is our side of the planning.
- We talk through your home, your current heating and what you want from a heat pump.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
How to prepare
- Tell us about any building rules, permits or sign-in
- Clear the space around the indoor unit, or where it will go
- Keep pets and children away from the work area
Ask for a quote
Some jobs can be priced from pictures, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, the quote is fixed before anything goes ahead.
