System by system
Wall-mounted split systems
A wall-mounted split is the most common choice for a single room. One unit inside, one outside, connected by pipework, a cable and a drain, routed as agreed on the survey.
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.
Air conditioning for homes and businesses in Sanderstead
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, plus VRF systems for bigger commercial buildings. The right choice depends on the rooms, the building and how visible you want the indoor units to be, and we explain the options on the survey. When someone in Sanderstead asks us for air con, the first questions are normally price and who will fit it. Our typical prices are on the site, and every install is done by F-Gas qualified engineers.
Most single-room installs in Sanderstead are done in a day, with multi-room systems taking longer depending on pipe routes, and we leave the room clean and the controls explained.
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.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

What affects the quote in Sanderstead
Your quote is based on your property. We consider:
- What electrical work the job needs
- How easy the units are to reach
- The equipment or parts the job needs
No two properties are the same, so each one gets its own fixed-price quote. The equipment, how we reach it, the route between units and the work needed all play a part.
Helping us quote
When you contact us, these details help:
- The paperwork from the last service, if you have it
- The rating plate or label on any existing unit
- A photo of the consumer unit with the cover closed
Quotes don’t take long. Send a few details and photos, and we reply the same working day. Where a survey is needed, we arrange a time that suits you.
What an install looks like in Sanderstead
VOA council tax data show about 39% of homes in Sanderstead and the neighbourhoods around it date from 1919 to 1939, and the last census (2021) found about 84% of households in detached or semi-detached houses. We check the wall construction on homes of that age, as it decides how the pipework goes through. A side passage or back wall normally gives the outdoor unit a home, and more than one bedroom can be cooled through a multi-split. London installs often hinge on outside space, the lease and access to the building.
If your home is in one of the older streets near Church of All Saints, it’s worth checking whether it’s listed or in a conservation area before an install. About 2.3 miles north-east stands Addington Palace. Listed homes in any area need consent first, so tell us if yours is one.

Questions from Sanderstead
Do you cover Sanderstead for air conditioning?
We do: Sanderstead falls inside our working area. Just phone us on 07833 053749 or drop us a line with a few details.
Is planning permission needed for air conditioning in Sanderstead?
It depends on the property. Around 4 listed entries sit within 0.5 miles of central Sanderstead. 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 planning department at Croydon council, typically the authority for Sanderstead.
Do I need to service the system to keep the warranty?
For some brands, yes. Send us the make and model and we will tell you what the manufacturer expects, and book the service at the interval they recommend.
How do you size the system?
We size each room on the survey, from its size, glazing, orientation and use. Too small, and it runs flat out; too big, and it switches on and off and wastes energy and we explain the output we recommend.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is recorded and F-Gas records kept where they apply.
How much is air conditioning for one room?
A single-room split system is typically £1,200–£2,200 + VAT. A two-room multi-split is typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT, with supply, fitting, commissioning and F-Gas documentation included. You get a fixed price before any work starts.
Is air conditioning possible in a flat?
That depends on the lease, the building and where the outdoor unit could go. Balconies, flat roofs and rear walls can all work, subject to consent and the survey looks at every option. This is general information, not legal advice.
Honest limits
In fairness, there are a few things this work will not fix:
- Damp from leaks or a lack of ventilation
- Work that needs permission from a landlord or the council
- Stuffy rooms that need fresh air rather than cooling

How the visit works
We book the visit for a day and time that suit you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your photos or the details you gave us. If something is different, we talk it through with you before carrying on. From there, the work takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. For a job in Sanderstead, tell us about parking, permits and access to the building when you get in touch.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Next, a recommendation for each room and a fixed price.
- Then the work: units up, pipes and drain run, and a new circuit where necessary.
- Before it runs, the pipework is proved tight and put under vacuum.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Preparing for the visit
- Arrange for someone to be there to let us in
- Keep pets out of the rooms we are working in
- Unlock any gate, garage or side passage we need

Advice
A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
