Air source heat pumps in Castle Town, done properly
We install air source heat pumps in Castle Town and across West Sussex, and we are MCS certified. There are two kinds: air-to-water, which heats radiators or underfloor heating and your hot water, and air-to-air, which warms rooms through indoor units and can also cool. We help you work out which suits your home. Typical jobs include questions about the Boiler Upgrade Scheme and a boiler that’s getting old, across hot water cylinders, homes heated by oil, LPG or gas and radiator systems.
For a home around Castle Town 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, on top of the £7,500.
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.

Common questions in Castle Town
Will you come out to Castle Town?
Yes. Castle Town is within the area we cover across London and the South East. A few pictures and the postcode are enough to get things started.
Can I get the Boiler Upgrade Scheme grant in Castle Town?
Castle Town is in England, where the Boiler Upgrade Scheme runs. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. We hold MCS certification, so the application is ours to make for you.
Will I need planning consent for an air source heat pump?
It depends on the property and where the unit goes. Flats have tighter limits, conservation areas add conditions, and Article 4 directions can remove rights and we look at it during the survey.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is recorded, with F-Gas records where refrigerant work is involved.
Which manufacturers do you install and repair?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and explain why.
How long will it take to install a heat pump?
An installation takes from a couple of days to around a week, depending on the system and how much of the heating changes. The survey lets us set a firm programme, so phone us on 07833 053749 or email us to arrange one.
Do you offer emergency call-outs?
Yes, 24/7. Call the emergency line and tell us the make, the symptoms and any error code, and we’ll talk you through the next steps.
Fixed-price quotes for air source heat pumps in Castle Town
The diagnosis comes before the price. We look at:
- Whether it’s a simple split or a larger system
- Whether the existing supply is suitable
- The distance and route between the indoor and outdoor units
No two properties are the same, so each one gets its own fixed-price quote. The system, the access, the pipe routes and the parts involved all make a difference.
Helping us quote
You don’t need the technical terms. It helps if you can send:
- Wide photos of the room or the existing unit
- The fuse board and where it is in the property
- The outdoor side of the property, including any roof or flat area
To get a fixed-price quote, give us a ring on 07833 053749 or use the quote form with the address and a few details about the rooms or units involved. A few photos make it quicker. You will hear back from us the same working day.
What a heat pump looks like in Castle Town
The last census (2021) found about 65% of households in detached or semi-detached houses. Houses usually have space for an outdoor unit and a hot water cylinder. Castle Town’s centre is no more than about a third of a mile from the Upper Beeding, Hyde Street Conservation Area. In the mile around Castle Town’s centre, 3 conservation areas have been designated. The Old House, listed at grade II, is one of roughly 19 protected buildings and structures in the half-mile around Castle Town’s centre. That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where needed, we check with the local planning authority (normally Horsham council).
Historic houses such as Portslade Manor, about 4.2 miles south-east, are a reminder that listed homes need consent before a heat pump goes in. Period properties close to St Botolph's Church can suit a heat pump, though insulation and any heritage protection are checked first.

For landlords and property managers
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Let us know who will give us access and who the records should go to and we will copy in whoever needs it.
Keeping records across a portfolio is half the battle. Every visit is written up, plus the F-Gas records where refrigerant is involved, so you can show what was done and when.
The process
We keep the work area tidy as we go, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. On site, it takes from a couple of days to around a week, depending on the system and how much of the heating changes. If a lane or gateway near Castle Town is tight for a van, let us know and we will plan for it.
- We talk through your home, your current heating and what you want from a heat pump.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- Commissioning, MCS certification and a handover of the controls finish the job.
Getting ready for the visit
- Let us know where we can park and unload
- Make sure someone can let us in at the agreed time
- Tell us about access, such as roof hatches, high walls or locked plant areas

Hot water cylinders
Hot water from an air-to-water system is stored in a cylinder. Space for the cylinder is part of the survey particularly in homes with a combi boiler.
Outdoor unit position and planning
Where the outdoor unit goes depends on airflow, access and the route into the house. We also consider neighbours and noise, as MCS 020(a) includes a noise check.
From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
