Thamesmead: your questions answered
Can I get a fixed-price quote for air conditioning in Thamesmead?
Start with a short message: the address, what you need and a picture or two. Where photos are not enough, a survey comes first and the fixed-price quote follows.
Do you cover Thamesmead for air conditioning?
We do: Thamesmead falls inside our working area. Tell us a little about the job and we will take it from there.
Can you fit air conditioning in a leasehold flat?
It depends on the building and the lease. An outdoor unit can sometimes go on a balcony, roof or rear wall, with consent and the survey looks at every option. This is general information, not legal advice.
Can the outdoor unit go on a roof or at ground level?
We agree it with you on the survey. It needs space around it to breathe and room for an engineer to service it, and a position facing a road can bring extra planning considerations. We will tell you what to check before we fit it.
How long does air conditioning installation take?
It takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. The survey tells us how long your installation will need so there are no surprises.
How do you size the system?
Floor area is only part of it. Glazing, orientation, the roof and what goes on in the room all affect it, and we take them all into account on the survey.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need, and the quote is based on that.
Air con installers in Thamesmead
Most modern split systems run as heat pumps, so they can heat as well as cool. The Energy Saving Trust makes the same point: an air-to-air heat pump is what many people simply call air conditioning, and a well-chosen system can earn its keep all year round. Most split systems we fit in Thamesmead are reversible: the Energy Saving Trust notes that air-to-air heat pumps are sometimes called air conditioning, so a system bought for summer earns its keep in winter too.
Most single-room installs in Thamesmead are done in a day, while multi-split systems for several rooms can take longer.
In a London area like Thamesmead, many of the homes we’re asked about are flats, maisonettes and terraced 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.
Each manufacturer sets its own warranty period. Daikin, for instance, 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.

Rented and managed buildings
From a single flat to a whole estate, you get the same standard: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.
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.
When something else is needed
Before booking, it helps to know what’s not included:
- A building fabric problem such as single glazing or no loft insulation
- Problems with a gas boiler or the radiators
- Damp or condensation caused by leaks or poor ventilation in the building (that needs the cause fixing)
If you are not sure, just phone us on 07833 053749 or send an email and we’ll give you a straight answer before you book.
What the work covers
- Multi-split systems

Air conditioning in Thamesmead: local notes
The last census (2021) found about 46% of households live in flats. In flats, the lease and the freeholder usually decide where an outdoor unit can go, and the permitted development rules for flats are tighter. London installs often hinge on outside space, the lease and access to the building. In the mile around Thamesmead’s centre, 2 conservation areas have been designated. If your property is listed or sits inside a conservation area, expect us to raise planning at the survey and to speak to Greenwich council, normally the planning authority here where it’s needed.
Around St Paul, a quick check of the listing and conservation maps is part of planning any install. With historic houses such as Eastbury Manor House about 2.4 miles north-west, it’s a reminder that older homes nearby may be listed, which changes the planning rules.
Thamesmead is about 2 miles north-east of Plumstead, in Greater London. Across the SE28 area, we can help with air conditioning. Our Greater London coverage runs to 764 places, Thamesmead among them. We also work in Bromley, about 9 miles from Thamesmead.

Looking after it afterwards
Looking after it is simple, and it makes the next visit easier:
- Keep the room closed while it runs
- Choose a comfortable set temperature rather than the lowest
- Book an annual service
We recommend an annual service, and some manufacturers make servicing a warranty condition. 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.
How it works
The first job on site is protection: sheets over the floor and any furniture nearby and nothing is moved without asking you. After that, anything electrical is made safe and we start. It takes a day or more, depending on the number of rooms, the pipe routes and the access, and we clear up before we go. The more we can see beforehand, the smoother the visit to Thamesmead will be.
- First comes a site survey, or pictures and measurements for a straightforward job.
- The quote is fixed and shows the equipment, where each unit goes and what’s included.
- The indoor unit is fixed in place, the outside unit positioned, and the connecting runs put in tidily.
- Once the electrics are connected, the pipework is tested for leaks and put under vacuum before any refrigerant flows.
- We commission the system, show you the controls and leave the F-Gas records and the manufacturer’s warranty details.
Preparing for the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Keep pets out of the rooms we’re working in
- Tell us about access, such as roof hatches, high walls or locked plant areas
Getting a quote
For a fixed-price quote, ring 07833 053749, or email if that’s easier with the address and a few details about the rooms or units involved. A few pictures make it quicker. We reply to enquiries the same working day.
