Air conditioning around Northolt
The Valuation Office Agency’s council tax figures show about 42% of homes in and around Northolt 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. London installs often hinge on outside space, the lease and access to the building.
If you commute from Northolt Park station and work from home on other days, one wall-mounted unit in the home office is often all that’s needed. With historic houses such as Northolt Manor about 0.3 miles south, it’s a reminder that older homes nearby may be listed, which changes the planning rules.

Air con installers in Northolt
Thinking about air conditioning but not sure where to start? Just phone us on 07833 053749 or fill in the contact form with photos of the rooms and the outside of the property, and you will hear back from us the same working day to arrange a survey or a quote. People searching for “air con near me” in Northolt want two things: a sensible price and someone qualified. Our typical prices are on the site, and every install is done by F-Gas qualified engineers.
Most single-room installs in Northolt 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.
In Northolt, as across London, the rooms that get hottest are normally under the roof or behind large sunny windows. 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.
Each manufacturer sets its own warranty period. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

How the job changes from property to property
Multi-split systems
A two-room multi-split is typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT. The pipe routes to each room make the biggest difference to the price.
Ceiling cassettes
A cassette needs a void above the ceiling for the unit, pipework and drain, and many use a built-in condensate pump to lift the water away. The survey confirms the void and the drain route.
Managing agents and facilities teams in Northolt
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Let us know who will give us access and who the records should go to and we will copy in whoever needs it.
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. In a let or managed building, it’s worth agreeing who that operator is, and we can work for either side.
What we do, step by step
Each visit runs to the same pattern: agree the plan on site, protect the area, carry out the job, test what we’ve done and explain it all to you. The visit itself takes about a day for a single-room system, longer for multi-room and ducted systems. Let us know who controls access to the building in Northolt, as that saves time on the day.
- 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.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
How to prepare
- Let us know where we can park and unload
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Keep pets out of the rooms we are working in
Ask for a quote
Some jobs can be priced from photos, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.

FAQs for Northolt
Do I need permission to put air conditioning in my flat in Northolt?
Often, yes, but the lease and the freeholder normally 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.
Do I need planning permission for air conditioning in Northolt?
There’s no single answer: the building and the outdoor unit position decide it. There’s a conservation area, the Northolt Village Green Conservation Area, close to central Northolt. 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 the planning department at Ealing council, normally the authority for Northolt.
Do I need a new electrical circuit?
In most cases, yes: a dedicated circuit is needed. Under Part P, a new circuit has to be notified unless a registered competent person does it, and as NICEIC approved contractors we install and certify it as part of the job.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
What does it cost to install air conditioning?
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 photos.
Which accreditations do you hold?
As the law requires for refrigerant work, we are an F-Gas certified company. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Can I have air conditioning in a flat?
It depends on the building and the lease. 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.
What happens if it’s left?
The best time to plan air conditioning is before the hot weather, not during it. A rushed choice is often the wrong size or in the wrong place, which is costly to undo. A survey now gives time to choose properly. Approvals for flats in Northolt can take longer than the install itself.
Several rooms, units or sites on one quote often makes better use of the time. Mention every unit or room you need covered, and you will get one fixed price.

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.”
