FAQs for Coombe
Will a heat pump in Coombe need planning permission?
The answer turns on the property and where the outdoor unit would sit. The Coombe Hill Conservation Area is close to the centre of Coombe. 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 local planning authority (for Coombe, normally Kingston-Upon-Thames council) first.
Can you fit air conditioning in a London flat in Coombe?
In many cases, yes, once the lease and the building’s rules are checked. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
How does the warranty work?
It’s the manufacturer’s warranty, which varies by brand. For example, Daikin’s standard warranty on split air conditioning is 2 years, and we explain the terms for whichever brand you choose.
What accreditations do you have?
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 soon will you get back to me?
You’ll hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
Does the grant cover air-to-air heat pumps?
A £2,500 grant is available in some cases. It won’t apply if the system is an add-on next to a boiler, and it must cover the whole heating demand.
How long will it take to install a heat pump?
The work takes a few days on site, depending on the cylinder, the radiators and the pipework involved. The survey lets us set a firm programme, and you can call us on 07833 053749 to book it.
Air source heat pumps for homes and businesses in Coombe
Hot water from an air-to-water system is stored in a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. With air-to-air, hot water has to come from something else. If you are dealing with moving away from fossil-fuel heating and radiators that may be too small for a heat pump, we can help.
For flats in Coombe, the lease, the freeholder and the rules for flats all come into it. The planning rules for flats are stricter than for houses, and we check before designing.
Think of the paperwork as the system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

Homes in Coombe and heat pumps
About 45% of homes in and around Coombe were built between the wars, according to VOA council tax data, and the last census (2021) found about 81% 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. Detached and semi-detached houses normally have room for the outdoor unit and a cylinder. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
Historic houses such as Southside House, about 1.4 miles east, are a reminder that listed homes need consent before a heat pump goes in. If your home is one of the older properties near Christ Church New Malden, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.

Safe owner checks
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
Do not move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. If you need something moved, we can quote for it.
What we do, step by step
There’s very little for you to do on the day. Just let us in and point us to the units, or to where they’ll be fitted, and we take it from there. At the end, we tidy up and run through the work with you. If your building in Coombe has a managing agent, a concierge or sign-in rules, mention them when you book.
- It begins with your house and the heating it relies on now.
- We measure heat loss for every room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- You get a fixed price, with any grant and the VAT set out.
- Then it’s fitted, commissioned and registered with MCS.
Preparing for the visit
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Make sure we can reach the consumer unit or fuse board

Advice
Different systems, different jobs
Air-to-water heat pumps
Air-to-water systems work at lower temperatures than boilers, so radiator sizes matter.
Radiators and underfloor heating
Underfloor heating works well with heat pumps because it uses lower temperatures, and we can connect to it where it’s already in.

When it’s something else
We will always give you a straight diagnosis, so here’s what air source heat pumps won’t do:
- Gas boiler work, such as disconnecting the old boiler, which needs a Gas Safe registered engineer
- Getting planning permission or listed building consent on your behalf
- Insulation work, such as loft or cavity wall insulation
If in doubt, phone 07833 053749 or drop us a line and we’ll say what we think before you book.
