- Uncertainty over the right type and size of system
- Expensive direct electric heating
- An office, shop or restaurant that’s uncomfortable for staff and customers
How it works
Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. So on the day, you do not need a separate electrician for the electrical side. On site, it takes a day or more, depending on the number of rooms, the pipe routes and the access. The more we can see beforehand, the smoother the visit to Richmond upon Thames will be.
- You send photos, or we visit and survey the rooms and outside.
- Each room is sized and the unit positions agreed, then you get a fixed-price quote.
- We protect the area, then fit both halves of the system.
- We run and connect the pipes, cable and drain, then pressure test and evacuate the circuit.
- It’s switched on, checked and handed over with its records.
Preparing for the visit
- Name a contact who can meet us at the agreed time
- Unlock any gate, garage or side passage we need
- Make sure we can reach the consumer unit or fuse board

Air conditioning for homes and businesses in Richmond upon Thames
A new system normally needs a dedicated circuit from the fuse board. Under Part P, a new circuit is notifiable unless a registered competent person does it, and as NICEIC approved contractors we can install and certify it as part of the job. If you want air conditioning in Richmond upon Thames, you get one team and one number from survey to sign-off.
Across London, and in Richmond upon Thames too, a lot of air conditioning goes into flats and terraces rather than detached houses. That shapes the job: where the outdoor unit can go, how the pipework reaches it and who needs to agree first. A freeholder or managing agent often has a say in a flat, and we can give you the details they’ll ask for.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Questions from Richmond upon Thames
Can you fit air conditioning in a London flat in Richmond upon Thames?
Typically, 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.
Is Richmond upon Thames in your area for air conditioning?
Yes, Richmond upon Thames is within the area we cover. To start, call us on 07833 053749 or send an email with a few pictures.
Do you work on all makes?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and explain why.
Do you provide F-Gas records?
Yes. You get a written record of every visit, including F-Gas records for any refrigerant work. File them with the system’s paperwork.
How much does air conditioning installation cost?
A single-room split system is typically £1,200–£2,200 + VAT. Two rooms on a multi-split are typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT, including supply, installation, commissioning and F-Gas documentation. You get a fixed price before any work starts.
How does the warranty work?
It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition so it’s worth keeping the service records.
Can air conditioning heat my home as well?
Most of the time, yes. Running as a heat pump, it moves heat in from outside rather than making it from electricity alone. To replace your main heating, there are extra conditions, including for the £2,500 Boiler Upgrade Scheme grant for air-to-air heat pumps.
Before you call an engineer
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
On air conditioning, the filters in the indoor unit are usually the one part owners can clean, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Different systems, different jobs
Multi-split systems
You can mix indoor unit types on many multi-split systems, choosing what suits each room, depending on the model. The survey settles which units go where.
Outdoor unit positions
On flats and terraced houses, space outside is often the deciding factor. Every option is checked on the survey and we flag any consent you may need.

Homes in Richmond upon Thames and air conditioning
VOA council tax data put about 44% of homes in the Richmond upon Thames area before 1919, and the 2021 Census found about 56% of households live in flats. 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. In flats, the lease and the freeholder typically 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.

Pembroke Lodge, about 1.3 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.

What air conditioning can’t fix

- A building fabric problem such as single glazing or no loft insulation
- Work that needs permission from a landlord or the council
- Damp from leaks or a lack of ventilation

“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
