Air conditioning in Merton
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, with VRF for larger buildings. Which one suits you depends on the space, the building and how much of the unit you want to see, and we explain the options on the survey. Need an air conditioning installer for Merton? We’re based in East Grinstead and cover London and the South East, as an F-Gas certified company with NICEIC approval.
Planning permission isn’t normally needed for a house if the unit qualifies as permitted development, but listed buildings, conservation areas and flats need more care: we tell you at the survey if it applies.
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, and a multi-split can cover more rooms from one outdoor unit where space outside is short.
Whatever the visit, you get a written record: 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.

How we price air conditioning
A fixed price needs a few facts first. We check:
- How far the pipework has to run, and where
- The electrical supply and whether a new circuit is needed
- What kind of system it is
Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a system working harder than it should costs more to run. If you’re unsure, phone 07833 053749 and we’ll give you an honest view and a fixed price.
Asking for a quote
When you contact us, it’s useful to have:
- A few photos of the room and the wall the unit is on, or will go on
- A photo of the consumer unit with the cover closed
- Any error code or flashing light on the display
Want a quote for air conditioning? Please ring us on 07833 053749 or drop us a line with a few details about the property. We will explain what we’d recommend and why, then send a fixed-price quote before you commit to anything.
Why deal with it now?
Putting up with another summer of portable units and fans rarely makes sense. A fixed system removes the heat to the outside, runs more quietly in the room and can typically heat as well, so it earns its keep all year. If a lease or managing agent is involved in Merton, start the conversation early.
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 go through it with you.

What an install looks like in Merton
About 42% of homes across Merton and its surrounding area were built before 1919, according to VOA council tax data, and about 49% of households live in flats, according to the last census (2021). Older properties often mean solid walls and period details, so pipe runs are planned to stay neat and out of sight. 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.
Southside House, about 1.8 miles west, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.
Merton is about 1 mile south-east of Wimbledon, in Greater London. For air conditioning in and around Merton, it’s easy to get a fixed-price quote: please call 07833 053749. Our area covers London and the South East, including Merton. Across Greater London, we cover 764 places, and Merton is one of them.
Not far from Merton, a recent job of ours was on Parkside, Wimbledon (SW19), about 1 mile north-west: installing a Mitsubishi Electric multi-split system serving four bedrooms and the main living room. Read more
If you need air conditioning at a property on High Path, Pincott Road and Hayward Close or a nearby road, our engineers can take on the work. We work across SW19. If you’re just outside Merton, we cover Merton Abbey (1 mile east), South Wimbledon (1 mile north-west), Colliers Wood (1 mile east), Tooting Bec (1 mile north-east) and Summerstown (1 mile north). Within a short drive, we also cover London (7 miles north-east), City of Westminster (7 miles north), Marylebone (7 miles north) and Kensington (6 miles north).
Around Merton
Typical jobs here are in properties near The Nelson Arms, Wimbledon School of Art and Wandle Park and the streets around them. For rail, the closest station is Haydons Road station, roughly 0.8 miles north. Nearby you will also find Southside Wandsworth (2.8 miles north) and St George's Hospital (1.1 miles north-east). Green spaces nearby include Henman Hill and Merton Park Green Walks.
Signs you need air conditioning in Merton
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.
It’s time to call us if you’re dealing with:
- A loft conversion that’s too warm to use
- An ageing air conditioning system near the end of its life
- Working from home in a room that gets too warm
If you commute from Haydons Road station and work from home on other days, one wall-mounted unit in the home office is often all that is needed.
Questions to ask before you book
- Whether the price is fixed or an estimate
- What happens if the job turns out to be different on the day
- Proof of F-Gas company certification
Questions from Merton
Will air conditioning in Merton need planning permission?
It comes down to the building and the spot chosen for the outdoor unit. The Wandle Valley Conservation Area is close to the centre of Merton. An air-to-air system used for heating as well as cooling can be permitted development on a house if it meets the conditions, but a cooling-only unit is not covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where necessary, we check with Merton council, which is normally the planning authority for Merton.
Do I need permission to put air conditioning in my flat in Merton?
Often, yes, but the lease and the freeholder usually 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.
Which type of system should I choose?
There’s no single best type. A split suits one room, a multi-split several, a ducted system hides the unit, and a cassette spreads air across larger rooms. The survey ends with a recommendation and the reasons.
Do you offer emergency call-outs?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will tell you what to do first.
Can I do the refrigerant work myself?
No, not the refrigerant side. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Will you work on another installer’s system?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Send us the make and model, and any records you have.
Where does the outdoor unit go?
The position is agreed on the survey, not on the day. It must have clear airflow and space for servicing, and walls or roofs facing a road can raise planning questions. We will tell you what to check before we fit it.
How it works
Protection comes first: sheets over the floor and any furniture nearby, and we ask before moving anything. After that, anything electrical is made safe and we start. It takes a day or more, depending on the number of rooms, the pipe routes and the access, and we clear up before we go. Photos of the room and where the outdoor unit could go let us plan most of a visit to Merton in advance.
- We survey the property, or work from your photos for a simple job.
- Output, positions and price are settled before anything is booked.
- Sheets go down first, then the indoor unit and the condenser are mounted.
- Connections are made, checked for leaks and pulled down to a vacuum.
- We commission, show you the controls and leave the F-Gas and warranty paperwork.
How to prepare
- Keep pets and children away from the work area
- Name a contact who can meet us at the agreed time
- Mention any roof access, ladders or high-level work
How to get a quote
Some jobs can be priced from pictures, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, the quote is fixed before anything goes ahead.

“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.”
