Top-floor flats and rooms with big south- or west-facing windows tend to be the first to overheat in London. Many people start with one wall-mounted unit in the room that suffers most, while a multi-split serves several rooms from one outdoor unit, which helps where outside space is limited.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. Keep it with the system’s paperwork so it’s to hand next time.

Managing agents and facilities teams in Downe
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We can quote either party and send the records to whoever needs them.
Bigger systems bring extra duties: 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.
What else we do in Downe
Your questions about air conditioning in Downe
Will air conditioning in Downe need planning permission?
There’s no single answer: the building and the outdoor unit position decide it. There’s a conservation area, the Downe Conservation Area, close to central Downe. Permitted development only covers heat pumps that aren’t used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where needed, we check with the local planning authority (for Downe, typically Bromley council).
Can you fit air conditioning in a London flat in Downe?
Often, yes, but the lease and the freeholder typically 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.
Do I need to service the system to keep the warranty?
It can, for some brands. Send us the make and model and we will tell you what the manufacturer expects, and book the service at the interval they recommend.
What does F-Gas certified mean?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before you book and we will gladly show you ours.
Where does the outdoor unit go?
It can go on a wall bracket, at ground level or on a flat roof, wherever the pipe route, airflow and servicing access work best. We also think about noise near bedrooms and neighbours, and the position can affect planning.
Can air conditioning heat my home as well?
Yes, most modern split systems run as heat pumps, so they can heat a room in winter. The Energy Saving Trust points out that an air-to-air heat pump is often just called air conditioning. We confirm the heating function of the model we quote.
Do I get paperwork after the visit?
Yes. Every visit is written up, including F-Gas records for any refrigerant work. Keep them with the manual and the warranty documents.
Air conditioning in Downe: local notes
London installs often hinge on outside space, the lease and access to the building.
Around St Mary's Church, a quick check of the listing and conservation maps is part of planning any install. Down House, about 0.6 miles south, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.
Downe is about 4 miles south-west of Orpington, in Greater London. Whether you’re in the middle of Downe or further out, our engineers cover air conditioning, from a single room to a whole building. Downe is one of 764 towns, villages and districts in Greater London where we work for homes and businesses.
The closest recent job we can point to from Downe was on Station Road, Orpington (BR6), about 4 miles north-east: installing three Daikin cassette units in the main office area and a wall-mounted unit in the client meeting room. More about it
If you need air conditioning at a property on High Street, North End Lane and Belle Vue Road or a nearby road, our engineers can take on the work. We work across BR6 and the streets around it. We also cover Farthing Street (1 mile north-west), Hazelwood (1 mile east), Luxted (1 mile south), Leaves Green (1 mile west) and Single Street (2 miles south). Within a short drive, we also cover London (13 miles north-west), City of Westminster (15 miles north-west), Marylebone (15 miles north-west) and St Pancras (15 miles north-west).
Near you in Downe
Typical jobs here are in properties near The Queens Head pub, Charles Darwin School and South Park and the streets around them. The closest station to Downe is Chelsfield station, about 2.6 miles north-east. Nearby you’ll also find Crofton Roman Villa (2.7 miles north-east) and Princess Royal University Hospital (1.8 miles north). Open spaces near Downe include Downe Bank Nature Reserve and Betsom's Hill.
Why act early in Downe
New systems now use lower-impact refrigerants. From 2025, single splits under 3 kg can’t use refrigerants with a GWP over 750, which is why R32, with a GWP of 675, is now common. R410A, used in many older systems, has a GWP of 2088. Approvals for flats in Downe can take longer than the install itself.
No two properties are the same, so we price each one individually. The system, the access, the pipe routes and the parts involved all make a difference.

How we price air conditioning
The diagnosis comes before the price. The main factors are:
- Whether we need access equipment for high-level work
- The equipment or parts the job needs
- The electrical supply and whether a new circuit is needed
The pipe route, the height of the units and how we reach them all affect the cost. We take each of them into account and give you a fixed price before any work starts.
What we need to know
Before you ask for a quote, gather:
- A close-up of the unit’s label showing the model number
- Any previous service or F-Gas records
- Where the property is and what kind of building it is

The process
The visit goes in the diary at a time that works for you, and we let you know if plans need to move. On arrival, the engineer compares the job with the survey, your pictures or the details you gave us. If something is different, we talk it through with you before carrying on. From there, the work takes anything from a day for one room to several days for a multi-room or ducted system. A note on parking and access helps us plan a visit to Downe.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Next, a recommendation for each room and a fixed price.
- Then the work: units up, pipes and drain run, and a new circuit where needed.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Preparing for the visit
- Have the make and model of any existing unit to hand
- Plan for pets to be kept clear during the visit
- Clear access to the fuse board
Getting a quote
Our prices page gives typical ranges, but your quote is based on your job, because no two buildings, rooms or systems are the same. After a look at the job, by pictures or a survey, the price is fixed. To start, give us a ring on 07833 053749 or email us.
