Air conditioning in Blackheath: local notes
About 42% of homes across Blackheath and its surrounding area were built before 1919, according to VOA council tax data, and about 66% of households live in flats, according to Census 2021 figures. Older properties often mean solid walls and period details, so pipe runs are planned to stay neat and out of sight. In flats, the lease and the freeholder normally decide where an outdoor unit can go, and the permitted development rules for flats are tighter. In London, outdoor unit positions, building rules and access tend to need more planning than the install itself.
If your home is in one of the older streets near Church of All Saints, it’s worth checking whether it’s listed or in a conservation area before an install.

Air conditioning for homes and businesses in Blackheath
We approach an installation much as a doctor approaches a patient: survey first, install second, commission and hand over last. At sign-off, the system is tested in each mode, the controls are explained and the F-Gas records are left with you. Air con, air conditioning, a split system: whatever you call it, it’s the job we do every week across Greater London.
Planning permission is not usually needed for a house if the unit qualifies as permitted development, but listed buildings, conservation areas and flats often need consent first: we tell you at the survey if it applies.
In a London area like Blackheath, many of the homes we’re asked about are flats, maisonettes and terraced houses. So the first questions are where the outdoor unit can sit, how the pipes get to it and whose permission is needed. In a flat, the lease and the freeholder normally come into it, and we can give you the details they’ll ask for.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

When something else is needed
To be straight with you, some problems need a different answer:
- Damp from leaks or a lack of ventilation
- A lack of fresh air (most split systems recirculate room air rather than bringing fresh air in, which is a job for ventilation)
- A room that cannot take an outdoor unit or pipe route without the landlord’s, management company’s or council’s consent (that consent comes first)
Not sure which it is? You can ring us on 07833 053749 or use the quote form and we’ll tell you honestly before you book.

The process
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. You only need to give us clear access to the units, or their planned positions, and to the fuse board. On site, the work takes a day or more, depending on the number of rooms, the pipe routes and the access. In a London area like Blackheath, parking and access are worth sorting out before the day.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Next, a recommendation for each room and a fixed price.
- Then the work: units up, pipes and drain run, and a new circuit where necessary.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
How to prepare
- Dig out any previous service or F-Gas records
- Unlock any gate, garage or side passage we need
- Name a contact who can meet us at the agreed time

Questions from Blackheath
Can I have air conditioning in a flat in Blackheath?
Normally, yes, though leaseholders normally need the freeholder’s agreement. 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.
Can I fit air conditioning in Blackheath without planning permission?
The answer turns on the property and where the outdoor unit would sit. The centre of Blackheath is in the Blackheath Conservation Area. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to Lewisham council, which is normally the planning authority for Blackheath when it matters.
Do you look at the job first?
Yes. Photos often do the job for simple work, while bigger systems and repairs that need testing get a visit.
Can you come out in an emergency?
Yes, any time. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we’ll tell you what to do first.
Will skipping a service affect the warranty?
It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Either way, keep a record of every service.
Can I use air conditioning to heat a room?
Most of the time, yes: modern splits are normally heat pumps, so they heat as well as cool. The Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. We confirm the heating function of the model we quote.
Will you need to do electrical work?
Most systems need their own supply from the consumer unit. Under Part P, a new circuit has to be notified unless a registered competent person does it, and as NICEIC approved contractors we install and certify it as part of the job.
Leave it or put it right?
Refrigerant rules have changed what new systems use. From 2025, single splits under 3 kg cannot use refrigerants with a GWP over 750, which is why R32, with a GWP of 675, is now common. Older R410A systems have a GWP of 2088. If a lease or managing agent is involved in Blackheath, start the conversation early.
Homes, offices, shops and public buildings are all priced the same way: the equipment, the access, the work involved and the time it takes. Ask for a fixed-price quote and we will go through it with you.
