Air source heat pumps in Chailey, done properly
For an air-to-water heat pump, the price is £8,000–£16,000 (0% VAT on homes), before the grant. The Boiler Upgrade Scheme can provide £7,500 towards an eligible air-to-water system in England and Wales and the installer makes the application. Not every home qualifies, so we check eligibility before you commit. The work covers homes heated by oil, LPG or gas, air-to-air heat pumps and radiator systems, and the jobs we see most are working out where a cylinder could go and questions about the Boiler Upgrade Scheme.
For a home around Chailey that is off mains gas and heated by oil or LPG, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027, on top of the £7,500.
We’re an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Questions from Chailey
Will a heat pump in Chailey need planning permission?
The answer turns on the property and where the outdoor unit would sit. Historic England lists about 18 buildings and structures within half a mile of the centre of Chailey. 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 planning department at Lewes council, typically the authority for Chailey.
Is Chailey within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Should I choose air-to-water or air-to-air?
Air-to-water replaces the boiler for heating and hot water, while air-to-air heats and cools rooms. The survey helps decide. We install both types.
Why use an F-Gas certified company?
Certification shows a business is approved to work on systems that hold F gas refrigerant. In Great Britain, that certification is a legal requirement, not an optional extra, and AirCon Doctor is certified.
Are you F-Gas certified?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, and we’re Checkatrade members. Engineers who handle refrigerant hold their own F-gas qualifications as well.
How long does a heat pump installation take?
Expect it to take 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.
Is the equipment covered by a warranty?
The manufacturer provides it, on its own terms. Some brands make regular servicing a condition so it’s worth keeping the service records.
What affects the cost of air source heat pumps
Jobs vary more than people expect. The main factors:
- What state the existing equipment is in
- How many units are involved
- How easy the units are to reach
No two properties are the same, so we price each one individually. The system, the access, the pipe routes and the parts involved all make a difference.
What we need to know
Good photos often save a visit. Try to include:
- Your consumer unit or fuse board
- The outdoor side of the property, including any roof or flat area
- Wide photos of the room or the existing unit
VAT is set out clearly on every quote, and the rate that applies to your job is stated. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it in writing rather than guess. To get one, give us a ring on 07833 053749.
What happens on the day
We book the visit for a day and time that suit you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the photos you sent. If something is different, we talk it through with you before carrying on. From there, the work takes a few days on site, depending on the cylinder, the radiators and the pipework involved. For a place like Chailey, the timing is set with you and the travel is our side of the planning.
- First, a chat about the property and your goals for the heating.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- We recommend air-to-water or air-to-air and check the grant position.
- Installation follows on the agreed dates.
- We commission it, complete the MCS certificate and show you how to use it.
Preparing for the visit
- Find the manual or the paperwork for the system, if you have it
- Clear access to the fuse board
- Keep pets and children away from the work area

Why act early in Chailey
Choosing between air-to-water and air-to-air is easier with the facts. Air-to-water works with radiators and a cylinder, with a £7,500 grant for eligible homes, while air-to-air heats and cools rooms and has a £2,500 grant only in limited cases, and we explain which fits your home. An early booking makes the visit to Chailey easier to arrange.
Leaving a fault or an overdue service rarely makes the work cheaper. Small problems, from blocked filters to slow leaks, tend to get worse, and a struggling system uses more electricity to do less. If you’re unsure, ring us on 07833 053749 or use the quote form for straight advice and a fixed price.

Common problems we fix in Chailey
Many people look at heat pumps when an oil, LPG or gas boiler is getting old. 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.
The things we are asked about most are:
- Checking eligibility for a heat pump grant
- Deciding on the outdoor unit position
- Checking whether planning permission is needed
Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler.
What your quote should include
- How VAT is shown, and which rate applies
- Whether the quote is a fixed price
- Whether anyone has checked the property or the system first
