Air source heat pumps in Sheerwater
As an MCS certified installer, we fit air source heat pumps for homes in Sheerwater and the rest of Surrey. There are two kinds: air-to-water, which heats radiators or underfloor heating and your hot water, and air-to-air, which warms rooms through indoor units and can also cool. We help you work out which suits your home. If you’re dealing with checking emitters for a heat pump and deciding on the outdoor unit position, we can help.
In a place like Sheerwater, some homes are listed, because permitted development doesn’t apply within the grounds of a listed building, so we check consent first.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

Common problems we fix in Sheerwater
Extensions, renovations and loft conversions are a natural time to rethink the heating. It’s simpler to plan radiators, pipework and a cylinder while the builders are in.
It’s time to call us if you are dealing with:
- Working out whether radiators need upsizing
- Checking eligibility for a heat pump grant
- Working out where a cylinder could go
If your home is listed, like Botleys Mansion about 2.8 miles north, listed building consent comes before any heat pump work.

FAQs for Sheerwater
Is Sheerwater within the area you cover?
Yes, smaller places are covered as well as towns. Send a few details and pictures, and we reply the same working day.
Is the heat pump grant available in Sheerwater?
Yes, if the home and the heat pump meet the scheme’s rules: Sheerwater 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. You do not apply yourself: the MCS certified installer does, which is us.
What does F-Gas certified mean?
Companies working on equipment that contains F gas must be certified by an approved body, and the engineers need their own qualifications. It means the refrigerant in your system is handled legally.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water replaces the boiler for heating and hot water, while air-to-air heats and cools rooms. The survey helps decide. Both are part of what we install.
What does an air-to-water heat pump cost?
Expect £8,000–£16,000 for an air-to-water system, with 0% VAT on homes, before the grant is taken off. Where you land depends on the size of heat pump, any radiators that need changing and the hot water cylinder, and air-to-air systems are priced after a survey.
What warranty do I get?
It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition, so keep your service records.
Who is responsible for leak checks?
The operator of the equipment, working with qualified engineers. 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.
What we do, step by step
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First we check the system or the space against the plan, then we do the work, and finally everything is tested, recorded and explained. The middle part takes longest, which takes a few days for most air-to-water installations, with air-to-air systems often quicker. For a place like Sheerwater, the timing is set with you and the travel is our side of the planning.
- First we find out about the property, the heating you have now and what you are hoping for.
- 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.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- The system is commissioned and registered under MCS, and we show you how to use it.
Getting ready for the visit
- Mention any managing agent or landlord rules we need to follow
- Arrange for someone to be there to let us in
- Find the manual or the paperwork for the system, if you have it

Heat pumps in Sheerwater: local notes
The Basingstoke Canal Conservation Area lies close to the centre of Sheerwater, within about a third of a mile. In the mile around Sheerwater’s centre, 2 conservation areas have been designated. 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 local planning authority (normally Woking council). VOA council tax data date about 41% of homes in Sheerwater and the neighbourhoods around it to the post-war years, 1945 to 1972. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period.
Older homes near St. Michaels Church may need extra checks for planning and heat loss before a heat pump is designed.

System by system
Radiators and underfloor heating
Any radiator changes are set out in the quote, so the work is clear.
Outdoor unit position and planning
Permitted development conditions in England include an outdoor unit of no more than 1.5 m³ and must meet MCS 020(a) and not be used solely for cooling. It cannot be within the curtilage of a listed building.
Before you call an engineer
Owner care supports servicing; it does not replace it. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
What a customer said
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
