What the work involves, system by system
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. An older board may need extra work and we’ll tell you if yours does.
Wall-mounted split systems
For one room, a wall-mounted split is often the simplest answer. One unit inside, one outside, connected by pipework, a cable and a drain, with the route agreed on the survey.
How we handle air conditioning in Hayes
Not sure what you need, or where it would go? Send a few pictures of the rooms and the outside walls when you call 07833 053749, or email if that’s easier, and you’ll hear back from us the same working day about a survey or a fixed-price quote. Most enquiries from Hayes start with one hot room: a bedroom, a home office or a loft conversion. That is typically a single wall-mounted split, from £1,200 + VAT.
London homes in Hayes can be short of outside space, so the outdoor unit may end up on a rear wall, a flat roof or a balcony. Neighbours’ windows and noise matter as much as appearance when we choose the position, and we plan the pipe route so it’s as short and tidy as the building allows.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, ready for the next service or a warranty query.

Homes in Hayes and air conditioning
VOA council tax data show about 50% of homes across Hayes and its surrounding area date from 1919 to 1939. Homes of that age normally have cavity or solid brick walls, and we check which before planning the pipe route. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.
If your home is in one of the older streets near Church of St Mary, it’s worth checking whether it’s listed or in a conservation area before an install. With historic houses such as Northolt Manor about 3 miles north-east, it’s a reminder that older homes nearby may be listed, which changes the planning rules.
Hayes is about 8 miles east of Slough, in Greater London. From the centre of Hayes to the outskirts, we cover air conditioning, from small jobs to large ones. We cover 764 places across Greater London, large and small. The nearest of our city pages is London, around 14 miles from Hayes.
The closest recent job we can point to from Hayes was on King Street, Twickenham (TW1), about 6 miles south-east: installing a Samsung VRF system serving the restaurant dining area, bar, private dining room and kitchen extraction area: seven indoor units in total. More about it

What affects the cost of air conditioning
The price is fixed before any work begins. It’s based on:
- What electrical work the job needs
- The number of rooms, units or zones
- Which make and model is being fitted or worked on
Several rooms, units or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed price.
What to send for a quote
When you call or email, these details help:
- The rating plate or label on any existing unit
- The remote or wall controller showing any error
- The outdoor side of the property, including any roof or flat area
If you need air conditioning in Hayes, ring us on 07833 053749 or send an email. Let us know the type of property and what you need, plus some photos if they’re to hand. Enquiries get a reply the same working day.

FAQs for Hayes
Will air conditioning in Hayes need planning permission?
There’s no single answer: the building and the outdoor unit position decide it. There’s a conservation area, the Hayes Village Conservation Area, close to central Hayes. Put simply: reversible systems on houses can be permitted development, cooling-only ones can’t, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact Hillingdon council, which is normally the planning authority for Hayes.
Can I have air conditioning in a flat in Hayes?
Normally, yes, though leaseholders normally need the freeholder’s agreement. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
How much is air conditioning for one room?
From £1,200 + VAT for a single-room split, with a typical range of £1,200–£2,200 + VAT. That covers supply, installation, commissioning and the F-Gas paperwork and is fixed after a survey or from pictures.
How do I know what size unit to get?
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 we take them all into account on the survey.
How soon will you get back to me?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s the law, not just our preference, and it also matters for the manufacturer’s warranty. We are happy to quote for the full job, supply to commissioning.
Do you cover Hayes?
Yes. We cover Hayes and across Greater London, as part of our area across London and the South East. To book, phone 07833 053749 or email us.
How the visit works
Our engineers arrive at the time agreed with you and run through the plan before anything else. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. The work itself takes about a day for a single-room system, longer for multi-room and ducted systems. Some blocks in Hayes need contractor details in advance, so tell us what your building needs.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Before we arrive
- Tell us about any building rules, permits or sign-in
- Keep pets out of the rooms we are working in
- Make sure we can reach the consumer unit or fuse board

Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- File the paperwork with the manual
- Keep the room closed while it runs
- Avoid setting it far colder than you need
Questions after the installation go to the same number. Let us know what’s happening and any error code and we’ll help you sort it out.
Regular filter cleaning is the simplest thing you can do. Clean filters keep the air moving and help the system work as designed, so it uses less electricity for the same comfort.
What a customer said
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
