About our air source heat pumps in Coolham
Hot water from an air-to-water system is stored in a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. Air-to-air systems don’t heat hot water, so you’ll need another way to do that. The work covers air-to-air heat pumps, hot water cylinders and underfloor heating, and people most often call us about finding a place for the outdoor unit and working out where a cylinder could go.
For a home around Coolham that is off mains gas and heated by oil or LPG, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump.
Nothing is signed off by word of mouth: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. Keep it with the system’s paperwork so it’s to hand next time.

What affects the quote in Coolham
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether we need access equipment for high-level work
- A single visit or a regular plan
- The number of rooms, units or zones
Typical ranges are on our prices page, but your price depends on the job in front of us. Call for a fixed-price quote, and we’ll explain what it covers.
Asking for a quote
To speed up the quote, send us:
- A short video of any fault, such as a noise or a flashing light
- Any previous service or F-Gas records
- The postcode and whether it’s a home, flat or business
VAT is set out clearly on every quote, with the rate that applies to your job. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it on the quote. For a fixed-price quote, call 07833 053749, or email if that’s easier.
Coolham: your questions answered
Is planning permission needed for a heat pump in Coolham?
That depends on the building and where the outdoor unit goes. Historic England lists about 5 buildings and structures within half a mile of the centre of Coolham. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights don’t reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the local planning authority (for Coolham, normally Horsham council).
Can I get the Boiler Upgrade Scheme grant in Coolham?
Yes, the scheme covers homes in England, including Coolham, if they qualify. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. As an MCS certified installer, we apply for it on your behalf.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine, on all the main brands. Send us the make and model, and any records you have.
Can landlords and managing agents book you?
Yes. Homeowners, landlords, agents and businesses all book us in Coolham and across West Sussex. Tell us who should receive the paperwork.
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 systems are priced after a survey, with the VAT confirmed on your quote.
Do you cover Coolham?
Yes. Coolham is part of the area we cover, within the South East and London area we cover. We are based in East Grinstead, West Sussex.
How long will it take to install a heat pump?
It takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. The cylinder, the radiators and the pipework make the biggest difference and the timing is set out with your quote.
Do you need air source heat pumps in Coolham?
An ageing boiler is often the moment people start thinking about a heat pump. Planning the change before the boiler fails gives you time to survey, design and apply for any grant instead of making a rushed decision when the heating stops.
If any of these sounds familiar, it’s worth a diagnosis:
- Deciding on the outdoor unit position
- Moving away from fossil-fuel heating
- Checking eligibility for a heat pump grant
Every heat pump design starts with a room-by-room heat loss calculation.
Comparing quotes
- Who does the electrical work, and whether they can certify it
- If the quote is based on a survey, photos or a diagnosis
- Why the equipment they’re quoting suits the job
How it works
We keep the work area tidy as we go, with dust sheets down and offcuts and packaging cleared up. Any holes, fixings or cable routes are agreed with you before we drill. On site, it 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. Photos of the room and the outside of the property help us plan a visit to Coolham.
- We talk through your home, your current heating and what you want from a heat pump.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Before we arrive
- Let us know where the consumer unit is
- Find the manual or the paperwork for the system, if you have it
- Arrange for someone to be there to let us in
Getting a price
Here’s what helps us quote: the address and the type of property, a few photos, the make and model of any existing system and anything you’ve noticed, such as an error code or a noise. Once you have those, ring 07833 053749 or use the quote form.

How the job changes from property to property
Outdoor unit position and planning
Where the outdoor unit goes depends on airflow, access and the route into the house. Noise is part of the MCS 020(a) check, so we consider nearby homes too.
Air-to-water heat pumps
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. A £7,500 grant may be available through the Boiler Upgrade Scheme for eligible homes, and we apply for it as the installer.

What a heat pump looks like in Coolham
The Valuation Office Agency’s council tax figures show about 43% of homes in Coolham and the neighbourhoods around it were built in 2000 or later, and the 2021 Census found about 67% of households in detached or semi-detached houses. Newer homes usually lose less heat, which tends to suit a heat pump well. Detached and semi-detached houses normally have room for the outdoor unit and a cylinder.
If your home is one of the older properties near St Mary's Mission Church, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.
