About air conditioning in TW7
A new system normally needs a dedicated circuit from the fuse board. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and as NICEIC approved contractors we can install and certify it as part of the job. We are often asked to deal with old electric heaters you’d like to replace with something more efficient and rooms that get too hot to sleep or work in, on ducted systems, wall-mounted split systems and air-to-air heat pumps.
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. On site, it takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer.
- 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.
- 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.

Local landmarks in Isleworth
Typical jobs here are in properties near The George Inn, Old Deer Park and Kneller Hall Junior School and the streets around them. Other local landmarks include St Mary's Catholic Primary School (less than half a mile south-east), Gumley House RC Convent School (within half a mile south-east) and Church of All Saints (0.5 miles east). There’s a railway station in Isleworth itself: Isleworth station. A little further out are West Middlesex University Hospital (within half a mile north-east) and Museum of Army Music (1.4 miles south-west). The countryside around Isleworth includes Richmond Hill and Kew Gardens Lake.
Air conditioning across TW7: local notes
In TW7, as across England, the same permitted development rules apply: an air-to-air system that heats as well as cools can be permitted development on a house, but cooling-only units, listed buildings and outdoor units facing a road in conservation areas need more care.
Refrigerant work is done by F-gas qualified engineers for a certified company, and the electrics come under our NICEIC approval.
Isleworth: With historic houses such as Syon House about 0.9 miles north-east, it’s a reminder that older homes nearby may be listed, which changes the planning rules. Living close to Church of All Saints? Some older properties in parts like that are protected, and the survey finds out whether yours is.
Why deal with it now?
Planning ahead beats a rushed decision in a heatwave. A rushed choice is often the wrong size or in the wrong place, which is costly to undo. Booking the survey early gives you time to weigh up the options.
Questions to ask before booking
- Whether the price is fixed or an estimate
- Whether the quote shows VAT clearly
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
- What records you get at the end
Rented and managed buildings
Records are where property maintenance often slips. Each visit produces a dated record, plus the F-Gas records where refrigerant is involved, so you can show what was done and when.
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We can quote either party and send the records to whoever needs them.
Why it fails
Everything that uses electricity in a room ends up as heat. A home office with a couple of screens, or a meeting room with a few people in it, warms up quickly, even when it is not especially hot outside.
Any of these is worth a proper look:
- Rooms that get too hot to sleep or work in
- Commercial rooms that are too warm for staff
- A study or office that overheats during the day
- A loft room or top floor that bakes in summer
When it’s something else
Air conditioning can’t fix everything, and we will tell you before any work starts. It does not solve:
- Building damp that has a structural cause
- Central heating repairs
- Stuffy rooms that need fresh air rather than cooling
FAQs for TW7
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
How much does air conditioning installation cost?
A single-room split system is typically £1,200–£2,200 + VAT. Two rooms on a multi-split are 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. The price is fixed before we start.
Are you F-Gas certified?
We are an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We are also Checkatrade members.
Will skipping a service affect the warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim, so we explain the terms on your quote.
Do you offer emergency call-outs?
Yes, day and night. When you call, tell us the make, what’s happening and any error code, and we’ll advise on what to do next.
How does the warranty work?
The manufacturer provides it, on its own terms. Some terms depend on regular servicing by a qualified engineer so it’s worth keeping the service records.
Will you make a mess?
We start with protection: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
