Air conditioning installation in Catford
Air conditioning in Catford from an F-Gas certified company, with warranty terms explained brand by brand. We reply to enquiries the same working day.
- A system on old refrigerant that’s due for replacement
- Bedrooms and offices that overheat in summer
- A loft conversion that’s too warm to use
What affects the cost of air conditioning
The survey or diagnosis tells us what the work involves. The main factors are:
- The pipe route between the units
- Whether the existing supply is suitable
- The equipment or parts the job needs
Every job is different, so each one gets its own fixed-price quote. The equipment, how we reach it, the route between units and the work needed all play a part.
What we need to know
To help us quote quickly, please include:
- A close-up of the unit’s label showing the model number
- A photo of the consumer unit with the cover closed
- The outdoor side of the property, including any roof or flat area
For a fixed-price quote, call us on 07833 053749 with the address and a few details about the rooms or units involved. A few pictures make it quicker. You will hear back from us the same working day.
Air con installers in Catford
A new system normally needs a dedicated circuit from the fuse board. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and our NICEIC approval means we install and certify it ourselves. Every installation in Catford begins with a look at the rooms, the walls and where the outdoor unit can go, followed by a fixed-price quote with the brand, model and every part of the job set out.
Space outside is often tight in Catford, as in much of London, which means a rear wall bracket, a flat roof or a balcony is often the best spot for the outdoor unit. We look at noise towards neighbours and windows as well as looks, and the pipe run is planned to be short, neat and out of the way.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual, because it helps with any later warranty question.

System by system
Electrical supply
We check the consumer unit on the survey, so any extra electrical work is on the quote rather than a surprise on the day. An older board may need extra work and we’ll tell you if yours does.
Ceiling cassettes
For wide rooms, a cassette spreads the air more evenly than one wall unit with just a grille visible in the ceiling.
What an install looks like in Catford
VOA council tax data put about 68% of homes in Catford and the neighbourhoods around it before 1919, and about 51% of households live in flats, according to Census 2021 figures. Older homes often have solid walls, which take longer to core drill, so we plan pipe routes carefully and keep them as discreet as we can. 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.
If your home is in one of the older streets near Church of St Laurence and Community Centre, it’s worth checking whether it’s listed or in a conservation area before an install. With historic houses such as Eltham Palace about 2.8 miles east, it’s a reminder that older homes nearby may be listed, which changes the planning rules.
Catford is about 5 miles east of Streatham, in Greater London. Anywhere in SE6, we cover air conditioning. Catford is one of 764 towns, villages and districts in Greater London where we work for homes and businesses.
One of our jobs in Catford
Brownhill Road, Catford (SE6)
- Property
- A first floor flat in a converted Victorian house.
- Work carried out
- Installation of a Mitsubishi Electric wall-mounted unit in the main living area. The first floor south-facing flat experienced temperatures exceeding 33°C in summer. Consent was obtained from all leaseholders before installation, as required under the building’s lease terms.
- Outcome
- The tenant: who is also the leaseholder: reported that the flat had been effectively unliveable in summer before installation. The system is now used daily in summer and the heat pump function has also reduced winter heating bills compared to the previous reliance on electric panel heaters.
Our working area takes in SE6 and BR1 in full. Whether you’re on Bargery Road, Penerley Road and Inchmery Road or anywhere close by, our engineers can take on the work. We also cover the places around Catford: Bellingham (1 mile south-west), Southend (1 mile south-west), Ladywell (1 mile north), Hither Green (1 mile north-east) and Bell Green (1 mile south-west). Within a short drive, we also cover London (5 miles north-west), City of Westminster (8 miles north-west), Marylebone (8 miles north-west) and Kensington (9 miles north-west).
What’s near Catford
We fit and service air conditioning in homes and premises around The London & Rye pub, Trinity Church of England School and Forster Memorial Park and the streets around them. The closest station to Catford is Catford Bridge station, roughly 0.5 miles north-west. A little further out are Greenwich Castle (2.6 miles north) and University Hospital Lewisham (0.8 miles north). For a walk, there’s Downham Woodland Walk and Knight's Hill.
What happens on the day
Testing is the last part of the visit wherever the system can be switched on. Then we explain what was done and answer your questions, and anything that needs a follow-up is pointed out there and then. All told, the work takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in Catford.
- We survey the rooms and the outside of the property, or work from pictures and details for simple jobs.
- You receive one fixed figure covering the kit, the fitting and the positions we agreed.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- The electrical supply is connected, and the refrigerant circuit is pressure tested and evacuated.
- Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.
Preparing for the visit
- Let us know where we can park and unload
- Mention any managing agent or landlord rules we need to follow
- Make sure we can reach the consumer unit or fuse board

Let and managed properties
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 each one has its own history.
Larger air conditioning systems in buildings need more than servicing: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We arrange the inspection, get the system ready and put right anything it picks up.
Catford: your questions answered
Do I need permission to put air conditioning in my flat in Catford?
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.
Is planning permission needed for air conditioning in Catford?
There’s no single answer: the building and the outdoor unit position decide it. The centre of Catford is in the Culverley Green Conservation Area. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact Lewisham council, which is typically the planning authority for Catford.
Do you look at the job first?
Yes, always. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need, and the quote is based on that.
Who is responsible for leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is recorded and F-Gas records kept where they apply.
Can I use air conditioning to heat a room?
Yes, most modern split systems run as heat pumps, so they heat as well as cool. The Energy Saving Trust points out that an air-to-air heat pump is often just called air conditioning. Some cooling-only models exist, so we confirm it for the model on your quote.
How much does air conditioning installation cost?
Single-room systems start from £1,200 + VAT and are typically up to £2,200 + VAT. The price includes supply, installation, commissioning and F-Gas documentation and is fixed after a survey or from pictures.
