Heat pump installers in Lewes
Air source heat pumps in Lewes from an F-Gas certified company, with the manufacturer’s warranty terms explained on your quote. Enquiries answered the same working day.
- An oil, LPG or gas boiler near the end of its life
- Plans to switch to electric heating with a heat pump
- Deciding on the outdoor unit position
What happens if it’s left?
A heat pump sized without a proper heat loss survey can struggle in cold weather or run inefficiently. A room-by-room survey gets it right first time. A dirty or faulty system works harder and costs more to run.
What you pay reflects the actual work. That is why every job is looked at first, and why the quote is fixed before we start.

How we handle air source heat pumps in Lewes
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 as the installer we apply for it on your behalf. Not every home qualifies, so we check eligibility before you commit. Typical jobs include radiators that may be too small for a heat pump and deciding which kind of heat pump suits the home, on underfloor heating, radiator systems and air-to-water heat pumps.
Around Lewes, most people asking about heat pumps have a gas boiler now. A survey looks at heat loss, radiators, the hot water cylinder and where the outdoor unit can go, then design the system.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Do you need air source heat pumps in Lewes?
Some homes heated by electric heaters or storage heaters consider a heat pump instead. A survey shows whether a heat pump suits the property and what would need to change, and we explain the grant position for your home.
These are the situations we see most often:
- A boiler that’s getting old
- Questions about listed buildings or conservation areas
- Plans to switch to electric heating with a heat pump
Live in one of the older houses around Church of St John sub Castro? Expect the survey to look closely at heat loss and at the building’s planning status.
What to look for in a quote
- What records you get at the end
- Exactly what the price includes, from supply and fitting to commissioning
- Whether they hold F-Gas company certification, not just individual qualifications
How the visit works
The work area is kept tidy throughout, with sheets down and mess cleared as we go. If we need to drill through a wall, we agree the spot with you first. On site, it takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Send us a few phone photos and we can plan most of the visit to Lewes.
- First we talk through the property and the current system.
- We measure heat loss for every room.
- We design the system, check the radiators and cylinder and look at the outdoor unit position.
- You get a fixed price, with any grant and the VAT set out.
- We install, commission and register the system under MCS.
How to prepare
- Clear the space around the indoor unit, or where it will go
- Let us know where the consumer unit is
- Mention any roof access, ladders or high-level work
Ask for a quote
VAT is set out clearly on every quote, and the rate that applies to your job is stated. VAT can differ between homes and businesses and between kinds of work, so we confirm it in writing rather than guess. To get one, phone 07833 053749 or email us.

How we price air source heat pumps
Some jobs are bigger than they look, and some smaller. The main factors:
- The distance and route between the indoor and outdoor units
- One-off work versus a regular service cycle
- Whether it’s a simple split or a larger system
No two properties are the same, so each one gets its own fixed-price quote. The equipment, how we reach it, the route between units and the work needed all make a difference.
Helping us quote
There’s no need for technical detail. Just send:
- Photos showing the indoor unit and the space around it
- The outdoor side of the property, including any roof or flat area
- The remote or wall controller showing any error

Questions from Lewes
Is planning permission needed for a heat pump in Lewes?
It depends on the property. Central Lewes sits inside the Lewes Conservation Area. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit can’t face a road. Where needed, we check with the planning department at Lewes council, typically the authority for Lewes.
Is Lewes in your area for air source heat pumps?
Yes. Lewes is one of the places we cover. Just call 07833 053749, or email if that’s easier with a few details.
Are you F-Gas certified?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, and we are Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
How much VAT is charged on a heat pump in a home?
Not on a home installation at the moment: HMRC zero-rates heat pumps installed in residential accommodation until 31 March 2027, and 5% applies after that. The relief is not available to businesses, and with air-to-air we confirm the VAT on the quote. This is general information, not tax advice.
Do you work on systems someone else installed?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
Do you look at the job first?
Yes, every time. We diagnose before we treat: the survey tells us what the job needs and how to do it, and the quote is based on that.
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.”
