Single Room Air Conditioning Installation

From £2,750, fully fitted. One indoor wall unit, one outdoor compressor, one day on site. Whisper-quiet cooling and heating for the room you actually use most.

A single-room split is the most popular air-conditioning system we install. Bedroom, home office, frequently used living room, conservatory. One Bosch Climate inverter unit handles cooling all summer, gentle heating through the colder months, and dehumidification on muggy days.

Who a single-room split is right for

You're cooling one room consistently. Maybe two if they're adjacent and you'll leave the door open. You want the system fitted fast, the running cost low, and the indoor unit to disappear into the décor.

The classic use cases:

Bedroom cooling for sleep
UK summers are getting hotter and humid. A 21 dB indoor unit keeps a bedroom at 19°C overnight for pennies, and customers tell us the change to their sleep quality is the unexpected favourite benefit.
Home office
West-facing or south-facing rooms turn into ovens by midday. A split unit cools the room in under 15 minutes and keeps it stable through the working day.
Conservatory or garden room
Glazed extensions overheat brutally in summer. A single split makes them usable for a third more of the year.
Top-floor flat or loft conversion
Heat rises, and these rooms suffer worst. Targeted cooling means you don't need to overspend cooling the whole house.

What the install day actually looks like

A single-room split is a one-day job in most cases.

  • 08:00–09:00. Team arrives, dust-sheets the rooms, walks the agreed install plan with you
  • 09:00–12:00. Indoor unit bracket fitted, pipework run to the outdoor location, holes core-drilled where needed
  • 12:00–13:00. Outdoor compressor mounted and connected
  • 13:00–15:00. Refrigerant charged, system pressure-tested, electrical connection completed
  • 15:00–16:30. Commissioning, app setup, walk-through with you on how to use it
  • 16:30–17:00. Tidy up, paperwork, leave the house clean

Most customers go from "the team arrived this morning" to "it's installed and running by tea time."

Running costs

Cooling a single bedroom overnight: typically under 35p on a standard electricity tariff. Less than running your oven for 45 minutes.

If you have solar, daytime cooling costs effectively zero. If you have solar plus a battery on an off-peak tariff, even overnight cooling drops to 5 to 10p per night.

In heating mode through shoulder months and mild winter days, the same unit runs at up to 510% efficiency. One kWh of electricity delivers up to 5.1 kWh of heat. That makes it significantly cheaper per kWh of useful heat than mains gas heating, and dramatically cheaper than plug-in electric heaters.

Pricing

From £2,750, fully fitted and certified.

The final number depends on a few survey-stage variables: which Bosch model best fits the room size, how far the outdoor unit sits from the indoor unit (longer pipework runs cost a little more), and whether there's any electrical work needed at the consumer unit.

Finance available on all installations. SAVE £300 when you install air-conditioning alongside a Solar and Battery system from Greenscape.

The two technicians, Luke & Cam arrived as scheduled, were courteous and respectful. They carried out the work as requested and invited me to inspect what they had done. Luke also clarified and guided me through a particular aspect on the Solis App.

As usual, Greenscape customer service resolved my query quickly and professionally. I had a query about winter settings for my batteries which Chloe resolved for me and then sent a follow up email to confirm all is in place. Thank you!

Harry fixed a persistent problem we've had for years. Over the last 4 years, a number of engineers had a go at fixing this but without success. Very happy with Harry and the knowledge he had of the Mitsubishi system

Both Brandon and young apprentice Ellis arrived on time to install my long awaited Pylontech battery. What can I say, they were very smart, professional and most polite. Greenscape have a good team here, please retain them and do pass on my best regards to them both. Cheers Paul

Chloe was very helpful with my winter settings, my app wasn’t the same as the written instructions but she just did it for me and then checked to see it was all working correctly.

I have used Greenscape Energy to install Solar Panels and Tesla Powerwall batteries and I can confidently state that they are an excellent company to deal with. I recently had a minor problem with the batteries not being charged during the cheap rate. Greenscape could not have been more helpful and put me in contact with Tesla to resolve the problem. Fantastic service from a professional company.

Michaela, dealt with my finance query in a professional, efficient manner, and placated my fears that the progress on my solar system would be paused until the return of the surveyor from holiday. Good customer care. Thank you

I have been very impressed with the service I received from Greenscape. The initial survey was very professionally done by Andrew and I was pleased that he convinced me not to have more panels than necessary. The team that installed the battery and inverter were excellent and very pleasant to deal with. The system is up and running and there have been no complications. I thoroughly recommend Greenscape.

I arranged to have solar panels and a battery installed by Greenscape via OVO Energy. From start to finish, the service has been excellent. From the survey, to the panel installation and battery installation, every team member has been professional and very friendly. The after sales have kept in contact to make sure everything has gone smoothly. Couldn't fault Greenscape.

Common questions

01 How long is the install?

One day on site for a standard single-room split. Occasionally a day and a half if the pipework run is unusually long or there's awkward electrical work.

02 How noisy is the indoor unit?

Bosch Climate units run as quiet as 21 dB, which is softer than a whisper and noticeably quieter than a fridge. You forget it's on.

03 Where does the outdoor unit go?

Usually wall-mounted on an external wall, or floor-mounted at ground level. We survey for the best position that minimises pipework, keeps the unit out of sight from the front of the property, and respects any neighbour considerations.

04 Can a single unit cool more than one room?

Technically yes if the rooms are adjacent and the doors stay open, but the system is sized for the room it's installed in. If you want consistent cooling across multiple rooms, a multi-room split is the right answer.

05 Do I need planning permission?

Almost never for a standard domestic single-room install in England. Permitted development covers most cases. Exceptions for listed buildings and conservation areas, which we check during the survey.
