Safe owner checks
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. Ask us to quote for a move instead.
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
How we handle air source heat pumps in South Malling
An air-to-water heat pump heats water to a lower temperature than a typical boiler which means some radiators may need upsizing. The survey shows which rooms are fine and which need changes and anything that needs changing is in the quote. The work covers air-to-water heat pumps, air-to-air heat pumps and radiator systems, and the jobs we see most are ageing boilers that will need replacing and wanting to stop using oil, LPG or gas for heating.
Older homes around South Malling can be draughty or have solid walls, so a proper heat loss calculation matters. Sometimes insulation first is the better investment.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

How the visit works
The work area is kept tidy throughout, 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. Let us know how to reach the outside wall or outdoor unit at your property near South Malling.
- You tell us about the home and what you want from a heat pump.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- We explain which type of heat pump suits the home and whether a grant could apply.
- The system is installed and connected to the controls.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Preparing for the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Arrange for someone to be there to let us in
- Tell us about any building rules, permits or sign-in
How to get a quote
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and simple jobs can often be priced without a visit.

What we are called out for in South Malling
For homes with no mains gas, heated by oil or LPG, a heat pump is well worth considering. Until March 2027, an extra £1,500 is available for air source and ground source heat pumps in homes heated by oil or LPG with no mains gas where the home is eligible.
Any of these is worth a proper look:
- A boiler that is getting old
- Working out where a cylinder could go
- Questions about listed buildings or conservation areas
Historic houses such as Anne of Cleves House, about 0.8 miles south-west, are a reminder that listed homes need consent before a heat pump goes in.
What your quote should include
- Whether anyone has checked the property or the system first
- What paperwork you’ll receive afterwards

Questions from South Malling
Do you cover smaller places like South Malling?
Yes. South Malling is within the area we cover across London and the South East. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Will a heat pump in South Malling need planning permission?
That depends on the building and where the outdoor unit goes. The Lewes (Malling Deanery) Conservation Area is close to the centre of South Malling. 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 the planning department at Lewes council, normally the authority for South Malling first.
Can I do any of the installation myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is a legal requirement, and it also matters for the manufacturer’s warranty. We’re happy to quote for the full job, supply to commissioning.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine, on all the main brands. Send us the make and model, and any records you have.
Can I get the Boiler Upgrade Scheme grant?
We check the scheme rules for your property before you go ahead. The installer applies for the grant, so we handle the application if you are eligible.
How long will it take to install a heat pump?
As a guide, it takes a few days for most air-to-water installations, with air-to-air systems often quicker. We plan the work so you’re without heating for as little time as possible and agreed before we start.
Will you make a mess?
Floors and furniture near the work are covered with dust sheets before any work starts, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
What a heat pump looks like in South Malling
The 2021 Census found about 37% of households in terraced houses. Terraced houses share walls with neighbours, which helps, but the outdoor unit position needs care with noise next door.
Live in one of the older houses around Church of St Michael? Expect the survey to look closely at heat loss and at the building’s planning status.

Running several properties is easier with one contractor. Our area covers Greater London and the South East, so a run of properties can go into one programme and kept to a regular schedule.
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.
From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
