Air conditioning installation in Coldharbour, Greater London
Air conditioning in and around Coldharbour, from the first look to the final check and a fixed price agreed before work begins.
- Old electric heaters you’d like to replace with something more efficient
- A portable unit with a hose out of the window
- An old system that needs replacing
How we price air conditioning
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether it’s a simple split or a larger system
- The brand, model and parts involved
- How far the pipework has to run, and where
Putting several jobs into one visit often makes better use of the time. Mention every unit or room you need covered and we will price it together.
Before you get in touch
The more you tell us, the more accurate the quote. With your enquiry, please include:
- The postcode and whether it’s a home, flat or business
- A few pictures of the room and the wall the unit is on, or will go on
- Any previous service or F-Gas records
Published ranges are a starting point; the quote is built on your property, because no two buildings, rooms or systems are the same. After a look at the job, by photos or a survey, the price is fixed. To get going, phone 07833 053749, or email if that’s easier.
How we handle air conditioning in Coldharbour
We install leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. The survey ends with a recommendation and the reasons for it, and the manufacturer’s warranty terms are set out on your quote. A lot of the calls we get from Coldharbour are about one room that’s too hot to sleep or work in. A single-room split system is often the answer, from £1,200 + VAT.
Across London, and in Coldharbour too, a lot of air conditioning goes into flats and terraces rather than detached houses. That shapes the job: where the outdoor unit can go, how the pipework reaches it and who needs to agree first. A freeholder or managing agent often has a say in a flat, so we write up the proposed positions for them to see.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Coldharbour: your questions answered
Do I need permission to put air conditioning in my flat in Coldharbour?
Often, yes, but the lease and the freeholder typically have a say. 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.
Is planning permission needed for air conditioning in Coldharbour?
It depends on the property. The centre of Coldharbour is in the Coldharbour Conservation Area. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the local planning authority (for Coldharbour, normally Tower Hamlets council) when it matters.
How long will the installation take?
Most single-room systems take a day. Multi-split, ducted and cassette systems take longer and the quote says how long to expect.
Who is responsible for leak checks?
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.
Can I do any of the installation myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s the law, not just our preference, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
Do I need a new electrical circuit?
Most systems need their own supply from the consumer unit. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and we’re NICEIC approved, so we can install and certify it.
Can air conditioning heat my home as well?
Typically, yes. Running as a heat pump, it moves heat in from outside rather than making it from electricity alone. If you want it to replace your main heating, ask about air-to-air heat pumps and the conditions for the Boiler Upgrade Scheme grant.
Honest limits
We will not sell you work that does not address the problem, so these are the things it won’t cover:
- A room that can’t take an outdoor unit or pipe route without the landlord’s, management company’s or council’s consent (that consent comes first)
- Building damp that has a structural cause
- A building fabric problem such as single glazing or no loft insulation
Not sure which it is? You can ring us on 07833 053749 or use the quote form and we’ll tell you honestly.

Homes in Coldharbour and air conditioning
About 82% of homes across Coldharbour and its surrounding area have been built since 2000, according to VOA council tax data, and about 95% of households live in flats, according to the last census (2021). Newer homes are often easier to fit, with cavity walls and space in the loft for pipework. In flats, the lease and the freeholder normally decide where an outdoor unit can go, and the permitted development rules for flats are tighter. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.
Living close to All Saints Church? Some older properties in parts like that are protected, and the survey finds out whether yours is. About 1.5 miles south stands Queen's House. Listed homes in any area need consent first, so tell us if yours is one.

How the visit works
Think of the visit in three stages: diagnose, treat and sign off. First we check the system or the space against the plan, then the work itself, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, and that takes about a day for a single-room system, longer for multi-room and ducted systems. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in Coldharbour.
- We survey the rooms and the outside of the property, or work from photos and details for simple jobs.
- We size the system for each room, then send a fixed-price quote with the units and where they go.
- The units go up and the pipework, cable and condensate drain are run neatly between them.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- The system is commissioned and checked in every mode, and we hand over the controls, F-Gas records and warranty information.
Preparing for the visit
- Let us know where the consumer unit is
- Move furniture away from the wall where we will be working
- Let us know if the units are on a roof, a high wall or in a locked area

Advice
Looking after it afterwards
Systems last better with the right care. We suggest:
- Wash or vacuum the filters as the manual describes
- Keep the F-Gas records, commissioning details and warranty information together
- Use moderate settings for comfort and economy
We recommend an annual service, and some manufacturers make regular servicing a condition of their warranty. We can remind you when it’s due, so it doesn’t get forgotten.
Regular filter cleaning is the simplest thing you can do. Clean filters keep the air moving and help the system work as designed, which costs you more to run.
