Air source heat pumps for homes and businesses in Coldharbour
Heat pumps run at lower flow temperatures than most boilers, so radiators may need to be larger to give out the same heat. The survey shows which rooms are fine and which need changes and anything that needs changing is in the quote. We are often asked to deal with checking whether planning permission is needed and comparing heat pump types, across hot water cylinders, homes heated by oil, LPG or gas and air-to-air heat pumps.
For flats in Coldharbour, the lease, the freeholder and the rules for flats all come into it. Permitted development limits are different for flats, so we check the position before we design.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

FAQs for Coldharbour
Do I need permission to put air conditioning in my flat in Coldharbour?
Often, yes, but the lease and the freeholder usually have a say. 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.
Will a heat pump in Coldharbour need planning permission?
The answer turns on the property and where the outdoor unit would sit. The centre of Coldharbour is in a conservation area. 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 do not 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 Bromley council, which is typically the planning authority for Coldharbour.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s the law, not just our preference, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
Will skipping a service affect the warranty?
That depends on the brand. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim, so we explain the terms on your quote.
Why use an F-Gas certified company?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That is not optional: it’s required by law, and AirCon Doctor is certified.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used and we will propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
Do you work for landlords and businesses?
Yes. From a single let flat to offices, shops and public buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
Air source heat pumps around Coldharbour
About 50% of homes in and around Coldharbour were built between the wars, according to VOA council tax data. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. For a London home, the outdoor unit position and the MCS noise check need careful planning.
For a home near Mottingham station, the survey looks at whether an air-to-water or air-to-air heat pump suits better.

What you can do yourself, and what needs us
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and call 07833 053749 or use the quote form.
Don’t 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. Ask us to quote for a move instead.

What we do, step by step
Protection comes first: sheets over the floor and any furniture nearby and nothing is moved without asking you. Then the electrics are made safe and the work begins. It takes from a couple of days to around a week, depending on the system and how much of the heating changes, and we clear up before we go. A few pictures of the room, the outside wall and the fuse board help us plan a job in Coldharbour.
- We start with your plans and the property.
- 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.
- After commissioning, you get the MCS certificate and a handover.
Getting ready for the visit
- Let us know where we can park and unload
- Let us know where the consumer unit is
- Give us access to the outside wall, roof or yard where the outdoor unit sits
