How we handle air source heat pumps in Castle Green
Air-to-water heat pumps heat your hot water through a cylinder. If you have a combi boiler and no cylinder, the survey looks at where one could go. Air-to-air systems don’t heat hot water, so you will need another way to do that. The work covers homes heated by oil, LPG or gas, hot water cylinders and air-to-water heat pumps, and people most often call us about wanting to stop using oil, LPG or gas for heating and no space for a hot water cylinder.
Homes around Castle Green typically have room outside for a heat pump, so the design focuses on heat loss and radiators.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

What a heat pump looks like in Castle Green
About 81% of households live in detached or semi-detached houses, according to Census 2021 figures. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these. There are 2 conservation areas within a mile of the centre of Castle Green. Listed buildings are part of the picture here: about 4 within half a mile of the centre, such as Castle Grove House (grade II). For a heat pump, permitted development does not apply within the grounds of a listed building, and in a conservation area the outdoor unit cannot go on a wall or roof facing a road, so we check with the local planning authority (usually Surrey Heath council) where necessary.
Older homes near Church of St Lawrence may need extra checks for planning and heat loss before a heat pump is designed. Historic houses such as Botleys Mansion, about 4.2 miles north-east, are a reminder that listed homes need consent before a heat pump goes in.

What owners can safely do
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. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Do not move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. If you need something moved, we can quote for it.
Rented and managed buildings
Facilities teams in offices, schools and public buildings book us too across Surrey. Larger buildings can be done in stages to keep disruption down.
Keeping records across a portfolio is half the battle. Each visit produces a dated record, plus the F-Gas records where refrigerant is involved, so you can show what was done and when.

Your questions about air source heat pumps in Castle Green
Do you cover smaller places like Castle Green?
Yes. Castle Green is within the area we cover across London and the South East. Send a few details and photos, and we reply the same working day.
Is the heat pump grant available in Castle Green?
Yes, the scheme covers homes in England, including Castle Green, if they qualify. 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.
Is the equipment covered by a warranty?
The manufacturer provides it, on its own terms. Some brands make regular servicing a condition so it’s worth keeping the service records.
Can you look at a system you didn’t fit?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Does servicing affect my warranty?
It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Keep every service record either way.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for problems that cannot wait for a planned visit. Call 07833 053749 and tell us what’s happened.
Do I need planning permission for a heat pump?
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. We check what applies to you.
When it’s something else
It’s worth knowing the limits before booking:
- Improving the building’s insulation

- Any gas work on the existing boiler
If you’re not sure, just give us a ring on 07833 053749, or email if that’s easier and we’ll give you a straight answer before booking.
