How we handle air conditioning in Cookham
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 talk you through it on the survey. A lot of the calls we get from Cookham are about one room that’s too hot to sleep or work in. That’s usually a single wall-mounted split, from £1,200 + VAT.
Most installations here are a wall-mounted indoor unit, a short pipe run through the wall and an outdoor unit on the back or side of the property, with the condensate drained away safely.
Around Cookham, older cottages and newer houses can be very different to work on. Thick walls, low ceilings and beams need care with pipe routes, and a listed home needs consent before anything is fixed to it.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

What happens if it’s left?
For homeowners, timing can matter for VAT: installing energy-saving materials in residential accommodation is zero-rated until 31 March 2027, then 5%. HMRC says most air conditioning units are air source heat pumps, but each case depends on the facts, so we confirm the VAT on your quote. This is general information, not tax advice. A dirty or faulty system works harder and costs more to run.
What you pay reflects the actual work. That’s why every job is looked at first, and the price is agreed before any work starts.

What we do, step by step
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. The visit takes a day or more, depending on the number of rooms, the pipe routes and the access. A few photos let us plan a visit to a place like Cookham.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- 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.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Preparing for the visit
- Have the make and model of any existing unit to hand
- Plan for pets to be kept clear during the visit
- Let us know where we can park and unload

Ducted systems
Ducted units can feed several rooms through a network of ducts, and they’re easiest to fit while ceilings are open, such as during a refurbishment.
Electrical supply
We check the consumer unit on the survey, so any extra electrical work is on the quote rather than a surprise on the day. Older boards sometimes need more work to take a new circuit and we will tell you if yours does.

Air conditioning in Cookham: local notes
Census 2021 figures found about 73% of households in detached or semi-detached houses. With homes like that, finding a sensible outdoor unit position is rarely hard, and a multi-split lets two or more rooms run off it.
Living close to Church of St John the Baptist? Some older properties in parts like that are protected, and the survey finds out whether yours is. With historic houses such as Cliveden about 1.7 miles east, it’s a reminder that older homes nearby may be listed, which changes the planning rules.

Portfolio owners often want one contractor and one number. Our area covers Greater London and the South East, so work at different addresses can be planned together and kept to a regular schedule.
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. Where a building is let or managed, the lease or contract should make clear who looks after the system, and we can work for either side.
FAQs for Cookham
Is planning permission needed for air conditioning in Cookham?
It comes down to the building and the spot chosen for the outdoor unit. The centre of Cookham is in a conservation area. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the planning department at Windsor and Maidenhead council, normally the authority for Cookham.
Can you do air conditioning in Cookham?
Yes, Cookham is within the area we cover. Get in touch with the details and we reply the same working day.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Which type of air conditioning is best?
Number of rooms, space outside and how much of the unit you want to see all decide it. Ducted systems need a ceiling void or loft, and cassettes need a suspended ceiling and the survey confirms what’s possible.
Will I get records for the system?
Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.
How long will the installation take?
A single-room system is usually fitted in a day. Multi-room and ducted systems take longer, depending on the pipe routes and access and the quote says how long to expect.
How do you size the system?
It depends on the room, not only its floor area. Glazing, orientation, the roof and what goes on in the room all affect it and the survey covers each of them.
What a customer said
“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.”
