Air conditioning for homes and businesses in Streatham
Across Streatham, every installation follows the same steps: survey, fixed-price quote, a neat installation, full commissioning and the F-Gas paperwork. The price is fixed up front and the records are handed over at the end. A lot of the calls we get from Streatham are about one room that is too hot to sleep or work in. A single-room split system is often the answer, from £1,200 + VAT.
Top-floor flats and rooms with big south- or west-facing windows tend to be the first to overheat in London. A single wall-mounted unit in the worst room is often where people start, while a multi-split serves several rooms from one outdoor unit, which helps where outside space is limited.
The records are your system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

Leave it or put it right?
The outdoor unit’s position is worth getting right first time. Placing it well keeps noise away from bedrooms and boundaries and makes servicing easier, and it can make a difference to planning. We agree it with you on the survey. Getting the work done in Streatham before summer avoids the busiest weeks.
Whatever the property, the quote works the same way: what’s needed, how we reach it, the parts and the labour. Call for a fixed-price quote and we’ll explain each part.

What we do, step by step
Each visit runs to the same pattern: agree the plan on site, put the dust sheets down, carry out the job, check the system and explain it all to you. The visit itself takes a day or more, depending on the number of rooms, the pipe routes and the access. In a London area like Streatham, parking and access are worth sorting out before the day.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- Each room is sized and you get a fixed-price quote setting out the equipment and the unit positions.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- Last comes the run-up: every mode checked, the controls explained and the paperwork left with you.
Before we arrive
- Make sure we can reach the consumer unit or fuse board
- Have the make and model of any existing unit to hand
- Mention any managing agent or landlord rules we need to follow
Getting a quote
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. Then you get a fixed price before any work starts.

Your questions about air conditioning in Streatham
Is air conditioning in Streatham permitted development?
It comes down to the building and the spot chosen for the outdoor unit. There’s a conservation area, the Streatham High Road and Streatham Hill Conservation Area, close to central Streatham. 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 Lambeth council, which is normally the planning authority for Streatham.
Do I need permission to put air conditioning in my flat in Streatham?
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.
What accreditations do you have?
We are an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re members of Checkatrade too.
Why use an F-Gas certified company?
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.
Do you protect the property while you work?
We start with protection: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
How do I know what size unit to get?
We size each room on the survey, from its size, glazing, orientation and use. An undersized unit never catches up, and an oversized one cycles and wastes energy and we explain the output we recommend.
Do you cover Streatham?
Yes. Streatham is part of the area we cover, as part of our area across London and the South East. Our base is in East Grinstead, West Sussex.
Common problems we fix in Streatham
Rooms in the roof are often the hardest to keep cool. Heat comes in through the roof and rises from the rest of the building, which is why a loft bedroom can still be warm at bedtime.
Most people get in touch after spotting one of these:
- Old electric heaters you’d like to replace with something more efficient
- Too many options and no clear advice
- A loft conversion that’s too warm to use
If you commute from Streatham station and work from home on other days, one wall-mounted unit in the home office is often all that is needed.

Homes in Streatham and air conditioning
About 55% of homes across Streatham and its surrounding area were built before 1919, according to the Valuation Office Agency’s council tax figures, and about 66% of households live in flats, according to the 2021 Census. 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. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.
If your home is in one of the older streets near St Leonard's Church, it’s worth checking whether it’s listed or in a conservation area before an install.

Owner checks or an engineer?
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
