How we price air source heat pumps
The quote reflects the job in front of us. We take into account:
- Access, including height, roofs and ladders
- How many units are involved
- Whether the existing supply is suitable
Several rooms, units or sites on one quote often makes better use of the time. Mention every unit or room you need covered and we’ll price it together.
Asking for a quote
Photos let us diagnose from a distance. The most useful are:
- Wide photos of the room or the existing unit
- Where the outdoor unit is, or where you’d like it
- Your installation or service records

How we handle air source heat pumps in Clayton
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. It has to replace the fossil-fuel heating, cover the whole heating demand, be fitted by an MCS certified installer and be in a home, so an add-on next to a boiler is not eligible. If you are dealing with comparing heat pump types and questions about listed buildings or conservation areas, we can sort it out.
In a place like Clayton, some homes are listed, because permitted development does not apply within the grounds of a listed building, so we check consent first.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

How the visit works
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. On site, 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. Seeing the property in pictures first means the trip to Clayton can be planned properly.
- You tell us about the home and what you want from a heat pump.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- We recommend air-to-water or air-to-air and check the grant position.
- We install the heat pump and connect it up.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Preparing for the visit
- Tell us about any building rules, permits or sign-in
- Name a contact who can meet us at the agreed time
- Give us access to the outside wall, roof or yard where the outdoor unit sits

Air source heat pumps around Clayton
VOA council tax data date about 42% of homes in the Clayton area to the post-war years, 1945 to 1972, and the 2021 Census found about 77% of households in detached or semi-detached houses. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Live in one of the older houses around St John the Baptist's Church? Expect the survey to look closely at heat loss and at the building’s planning status. If your home is listed, like Preston Manor & Gardens about 4.7 miles south, listed building consent comes before any heat pump work.

Your questions about air source heat pumps in Clayton
Can I fit a heat pump in Clayton without planning permission?
There’s no single answer: the building and the outdoor unit position decide it. Central Clayton is a short walk from the Clayton Conservation Area. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with Mid Sussex council, which is usually the planning authority for Clayton first.
Do you cover smaller places like Clayton?
Yes, and the size of the place makes no difference to how we work. Send a few details and pictures, and we reply the same working day.
Will my radiators work with a heat pump?
Some radiators may be fine as they are, and some may need to be larger. Heat pumps run at lower flow temperatures, so radiators give out less heat so we check every radiator against the room’s heat loss.
Can you set up regular servicing?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Each visit is written up, with F-Gas records where refrigerant work is involved.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us in Clayton and across West Sussex. Tell us who should receive the paperwork.
What VAT do I pay 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.
Which type of heat pump is right for my home?
Air-to-water replaces the boiler for heating and hot water, while air-to-air heats and cools rooms, and we help you choose. We install both types.
Let and managed properties
Larger air conditioning systems in buildings need more than servicing: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We can arrange it, prepare the system for it and fix what it finds.
We regularly work with managing agents. Tell us the property, the work and the access arrangements, and we will send a fixed-price quote.
Why deal with it now?
Planning rules have specific conditions. We look at the planning position early, so there are no surprises covering listed buildings, conservation areas and any Article 4 direction. Waiting rarely makes an air conditioning problem smaller.
No two properties are the same, so we price each one individually. The system, the access, the pipe routes and the parts involved all play a part.
