Air source heat pumps in Coldwaltham, done properly
Air source heat pumps collect heat from outdoor air and bring it inside with electricity running the compressor and fans. It works on the same principle as air conditioning, run the other way and the Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. The work covers air-to-water heat pumps, hot water cylinders and air-to-air heat pumps, and the jobs we see most are working out whether radiators need upsizing and deciding which kind of heat pump suits the home.
Older and listed homes in villages like Coldwaltham need extra care, because permitted development does not apply within the grounds of a listed building, so we check consent first.
Warranty periods vary by brand and by product. For example, 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.

Air source heat pumps in Coldwaltham: the local picture
About 43 miles out from central London, Coldwaltham is part of the South East area we work across. Roughly a third of a mile or less from central Coldwaltham, you reach the Coldwaltham (south) Conservation Area. In the mile around Coldwaltham’s centre, 3 conservation areas have been designated. About 13 listed entries lie within half a mile of central Coldwaltham, The Parish Church of St Giles (grade II*) among them. 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 planning team at Horsham council, which usually handles Coldwaltham where needed.
Live in one of the older houses around The Parish Church of St Giles? Expect the survey to look closely at heat loss and at the building’s planning status.

What we’re called out for in Coldwaltham
The Boiler Upgrade Scheme has made people ask whether their home could qualify. Whether you can get the grant depends on your home and the scheme conditions and we confirm it before you go ahead.
Look out for any of the following:
- Working out where a cylinder could go
- Moving away from fossil-fuel heating
- Finding a place for the outdoor unit
If your home is listed, like Old Place Manor about 2 miles north-east, listed building consent comes before any heat pump work.
Before you book anyone
- Whether extra work needs your approval first
- Which brand and model they’re proposing, and why
- Whether a new circuit is included and who certifies it
Why it’s worth doing now in Coldwaltham
Replacing a boiler in a hurry when it breaks leaves little time to consider a heat pump. Planning ahead gives time for the heat loss survey, the design and the grant application while the old heating still works. Getting the date in early helps for a place like Coldwaltham.
No two properties are the same, so each one gets its own fixed-price quote. The equipment, how we reach it, the route between units and the work needed all play a part.

Common questions in Coldwaltham
Is the heat pump grant available in Coldwaltham?
Yes, the scheme covers homes in England, including Coldwaltham, if they qualify. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. We hold MCS certification, so the application is ours to make for you.
Will you come out to Coldwaltham?
Yes. Coldwaltham is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
Do you work on all makes?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and tell you why.
What warranty do I get?
It’s the manufacturer’s warranty, which varies by brand. Daikin, for instance, gives a standard 2 years on split air conditioning, and we explain the terms for whichever brand you choose.
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. Either way, keep a record of every service.
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.
Do I get paperwork after the visit?
Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.

Then we explain what was done and answer your questions, and anything that needs a follow-up is pointed out there and then. All told, the work takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. A few photos help us make the most of a visit to Coldwaltham.
