FAQs for Crofton Park
Do I need permission to put air conditioning in my flat in Crofton Park?
Normally, yes, though leaseholders normally need the freeholder’s agreement. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Do I need planning permission for air conditioning in Crofton Park?
There’s no single answer: the building and the outdoor unit position decide it. There’s a conservation area, the Brockley Conservation Area, close to central Crofton Park. Put simply: reversible systems on houses can be permitted development, cooling-only ones can’t, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the local planning authority (for Crofton Park, normally Lewisham council).
How do I know what size unit to get?
We size each room on the survey, from its size, glazing, orientation and use. Too small, and it runs flat out; too big, and it switches on and off and wastes energy and we explain the output we recommend.
Will you make a mess?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. At the end, we clear up and show you what we have done.
Which accreditations do you hold?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, and we’re Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Is the equipment covered by a warranty?
It’s the manufacturer’s, and the terms are theirs. Some terms depend on regular servicing by a qualified engineer, so keep your service records.
Do you work on commercial properties?
Yes. Homeowners, landlords, agents and businesses all book us in Crofton Park and across Greater London. Let us know who the records should go to.
How we handle air conditioning in Crofton Park
We fit wall-mounted splits, multi-split systems, ducted systems and ceiling cassettes, with VRF for larger buildings. The right choice depends on the rooms, the building and how visible you want the indoor units to be and we talk you through it on the survey. Whether you call it air con, air conditioning or an air-to-air heat pump, in Crofton Park it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
Planning permission is not normally needed for a house if the unit qualifies as permitted development, but listed buildings, conservation areas and flats often need consent first: we flag that at the survey.
In a London area like Crofton Park, many of the homes we are 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. A freeholder or managing agent often has a say in a flat, and we can give you the details they’ll ask for.
The records are your 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.

Why act early in Crofton Park
Refrigerant rules have changed what new systems use. From 2025, single splits under 3 kg can’t use refrigerants with a GWP over 750, so new splits use refrigerants such as R32, with a GWP of 675. R410A, used in many older systems, has a GWP of 2088. Booking in spring means a home or office in Crofton Park is ready before the first hot week.
Leaving a fault or an overdue service rarely makes the work cheaper. Small problems, from blocked filters to slow leaks, tend to get worse, and a struggling system uses more electricity to do less. If you are not sure what’s needed, ring us on 07833 053749 for straight advice and a fixed price.

What an install looks like in Crofton Park
Valuation Office Agency council tax records put about 57% of homes in Crofton Park and the neighbourhoods around it before 1919, and about 50% of households live in flats, according to the last census (2021). Older properties often mean solid walls and period details, so pipe runs are planned to stay neat and out of sight. For a flat, we look at balconies, flat roofs and rear walls for the outdoor unit, and the lease often needs checking first. In London, outdoor unit positions, building rules and access tend to need more planning than the install itself.
With historic houses such as Queen's House about 2.4 miles north-east, it’s a reminder that older homes nearby may be listed, which changes the planning rules.

What happens on the day
The work area is kept tidy throughout, with dust sheets down and offcuts and packaging cleared up. Any holes, fixings or cable routes are agreed with you before we drill. On site, it takes about a day for a single-room system, longer for multi-room and ducted systems. Let us know who controls access to the building in Crofton Park, as that saves time on the day.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- Then the work: units up, pipes and drain run, and a new circuit where necessary.
- Before it runs, the pipework is proved tight and put under vacuum.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Getting ready for the visit
- Keep pets and children away from the work area
- Dig out any previous service or F-Gas records
- Let us know if the building has a permit or sign-in process
Getting a price
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your pictures and details. After that, we send a fixed price so you know the cost before we begin.

Common problems we fix in Crofton Park
Poor sleep is one of the most common reasons homeowners ask about air conditioning. Once a bedroom has soaked up heat during the day, opening a window may not bring the temperature down far enough, particularly when there’s no breeze.
It’s time to call us if you are dealing with:
- Fans and portables that don’t keep up
- A loft room or top floor that bakes in summer
- Rooms that get too hot to sleep or work in
If your home is in one of the older streets near Church of St Hilda, it’s worth checking whether it’s listed or in a conservation area before an install.

Landlords, agents and facilities managers
For anyone managing more than one building, we can quote and plan the work across all of them. Each property gets its own records, so the files stay tidy.
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is and we’re happy to deal with whoever it is.
What a customer said
“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.”
