About our air source heat pumps in Domewood
Hot water from an air-to-water system is stored in a cylinder. If you have a combi boiler and no cylinder, the survey looks at where one could go. With air-to-air, hot water has to come from something else. Typical jobs include comparing heat pump types and plans to switch to electric heating with a heat pump, on hot water cylinders, radiator systems and underfloor heating.
Space for an outdoor unit is rarely an issue near Domewood, so the design focuses on heat loss and radiators.
Warranty periods vary by brand and by product. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

Keeping the system healthy
To keep the system working properly:
- File the MCS certificate safely
- Keep up with insulation and draught-proofing
- Avoid switching the heat pump on and off often
In cold, damp weather the outdoor unit runs a defrost cycle from time to time. It may give off steam or sound different for a few minutes and it’s part of how the system works.
Have the system serviced regularly. Check the manufacturer’s terms, as they may include servicing conditions.
How it works
If the system has to be off for part of the visit, we tell you before we start, so you can plan around it. In a business, work can often be done one area at a time. On site, it takes from a couple of days to around a week, depending on the system and how much of the heating changes. Rural lanes and tight entrances are worth mentioning before a visit to Domewood.

What else we do in Domewood
When to call us in Domewood
Homes off the gas grid, heated by oil or LPG, are often good candidates to look at. Until March 2027, an extra £1,500 is available for air source and ground source heat pumps in homes heated by oil or LPG with no mains gas where the home is eligible.
Look out for any of the following:
- Choosing between air-to-water and air-to-air
- Questions about listed buildings or conservation areas
- Working out whether radiators need upsizing
If your home is listed, like Saint Hill Manor about 3.5 miles south-east, listed building consent comes before any heat pump work.

Domewood: your questions answered

What’s the price of a heat pump installation?
For air-to-water, it’s £8,000–£16,000 (0% VAT on homes) before any Boiler Upgrade Scheme grant. Air-to-air prices are set after a survey, and we confirm the VAT on the quote.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Let us know who the records should go to.
Do I need to service the system to keep the warranty?
Each manufacturer decides. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim, so we explain the terms on your quote.
Will I need planning consent for an air source heat pump?
In England, many air source heat pumps on houses can be permitted development provided the conditions are met. The outdoor unit must be 1.5 m³ or less, comply with MCS 020(a), not be cooling-only and not be within a listed building’s curtilage.
Is there VAT on a heat pump?
Under HMRC Notice 708/6, a heat pump installed in a home is zero-rated until 31 March 2027, then 5%. For air-to-air systems, we confirm the VAT on your quote.
