Air source heat pumps in Coates: the local picture
About 43% of homes in Coates and the neighbourhoods around it were built before 1919, according to the Valuation Office Agency’s council tax figures, and about 73% of households live in detached or semi-detached houses, according to the last census (2021). Period properties can still suit a heat pump, but the design has to start from accurate heat loss figures. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these. Roughly a third of a mile or less from central Coates, you reach the Coates Conservation Area. Draw a one-mile circle round the middle of Coates and it takes in 2 conservation areas. Listed buildings are part of the picture here: about 12 within half a mile of the centre, such as Church of St Agatha (grade I). So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area?
With Bignor Roman Villa about 2.1 miles south, it’s worth asking whether your own home is listed before planning a heat pump. If your home is one of the older properties near Church of St Agatha, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.

Air source heat pumps for homes and businesses in Coates
Every installation starts with a heat loss survey. It shows how much heat each room needs on a cold day, so the heat pump and the radiators or indoor units can be sized properly. Guesswork leads to systems that are too big or too small. The work covers air-to-air heat pumps, homes heated by oil, LPG or gas and radiator systems, and the jobs we see most are replacing a combi boiler with a heat pump and an oil, LPG or gas boiler near the end of its life.
If your home in or near Coates is heated by oil, LPG or electric heaters with no mains gas, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

Looking after it afterwards
Looking after the system is mostly common sense. Our tips:
- Check eligibility for the Boiler Upgrade Scheme early
- Check what your manufacturer’s warranty asks of you
- Keep the MCS certificate with the manufacturer’s paperwork
The warranty on the heat pump is the manufacturer’s, on its own terms. We go through the conditions with you, including any servicing they ask for.
Do not cover radiators with furniture or heavy curtains, as the system relies on them giving out heat.
What air source heat pumps cannot fix
Before booking, it helps to know what’s not included:
- Disconnecting or servicing a gas boiler
- A grant for a home that doesn’t meet the scheme rules
- Planning decisions, which rest with the council
Not sure which it is? You can phone us on 07833 053749 or send an email and we’ll tell you honestly.

Leave it or put it right?
The 0% VAT rate on heat pumps in homes runs until 31 March 2027, then 5% applies. If you’re thinking about a heat pump, that date is worth knowing alongside your own plans for the property. Dealing with it now is usually simpler than a breakdown later.
The pipe route, the height of the units and how we reach them can all change the price. Each of those is built into the quote, and the price is fixed before we start.

Coates questions
Is Coates within the area you cover?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can I get the Boiler Upgrade Scheme grant in Coates?
Yes, the scheme covers homes in England, including Coates, if they qualify. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. We hold MCS certification, so the application is ours to make for you.
Are my radiators big enough for a heat pump?
That depends on the room’s heat loss and the radiator’s size. The survey compares each radiator with the room’s needs and the quote shows what’s needed.
Do you look at the job first?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the job needs and how to do it and the fixed price is built on it.
How does the warranty work?
Warranty comes from the manufacturer and depends on the brand and product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and we explain the terms for whichever brand you choose.
When will I hear back?
You’ll hear from us the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
Can you look at a system you didn’t fit?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Tell us the make and model and send any paperwork you have.
