Air Source Heat Pumps in Three Leg Cross
Our engineers work in Three Leg Cross on heat pump installation. A look at the job first, a fixed-price quote and written records at the end.
- Questions about the Boiler Upgrade Scheme
- Working out whether radiators need upsizing
- Questions about listed buildings or conservation areas
How it works
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First we check the system or the space against the plan, then the work itself, and finally everything is tested, recorded and explained. The middle part takes longest, which takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Rural lanes and tight entrances are worth mentioning before a visit to Three Leg Cross.
- It starts with a conversation about the home, the existing heating and your plans.
- 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.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- Commissioning, MCS certification and a handover of the controls finish the job.
Getting ready for the visit
- Unlock any gate, garage or side passage we need
- Make sure someone can let us in at the agreed time
- Plan for pets to be kept clear during the visit

Air source heat pumps for homes and businesses in Three Leg Cross
Until 31 March 2027, a heat pump installed in residential accommodation carries 0% VAT, with 5% from 1 April 2027. That follows HMRC Notice 708/6, and it does not apply to businesses, and for air-to-air systems we confirm the VAT on your quote. Please treat this as general information rather than tax advice. We’re often asked to deal with not knowing whether a grant applies and radiators that may be too small for a heat pump, on underfloor heating, radiator systems and air-to-water heat pumps.
Space for an outdoor unit is rarely an issue near Three Leg Cross, so the design comes down to heat loss, radiators and hot water.
Aftercare is simple, and most of it is in the manual: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. That also helps where the warranty terms ask for regular servicing.

What a heat pump looks like in Three Leg Cross
The centre of Three Leg Cross lies within a conservation area. In the mile around Three Leg Cross’s centre, 2 conservation areas have been designated. Historic England lists about 13 buildings and structures within half a mile of the centre of Three Leg Cross, including Dunsters Mill House (grade II*). Where a home is affected, the outdoor unit position is settled with the local planning authority (usually Rother council) before the heat pump design is finished. Census 2021 figures found about 74% of households in detached or semi-detached houses. Detached and semi-detached houses usually have room for the outdoor unit and a cylinder.
If your home is listed, like Scotney Castle about 2.6 miles north, listed building consent comes before any heat pump work. Period properties close to St Mary's Church can suit a heat pump, though insulation and any heritage protection are checked first.

Looking after it afterwards
To keep the system working properly:
- Find out the grant position at the survey
- Leave indoor units unobstructed
- Seal draughts where you can
After commissioning, the installation is registered under MCS and you receive the certificate. Keep it with the manufacturer’s paperwork, as you may need it later.
Keep insulation and draught-proofing in good order because it reduces the heat the system needs to supply.
Leave it or put it right?
From 1 April 2027, VAT on heat pumps in homes rises from 0% to 5%. If you are thinking about a heat pump, that date is worth knowing, though the right time also depends on your home and heating. Small faults tend to grow, so it’s worth dealing with them early.
One room or a whole building, the quote is built the same way: what needs doing, how we get to it and what it needs. The price is fixed before work begins, and the quote sets out the VAT.

What you can do yourself, and what needs us
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
