Air conditioning in North Lee, done properly
A single-room split system is typically £1,200–£2,200 + VAT, two rooms on a multi-split £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT. Those ranges include supply, installation, commissioning and F-Gas documentation, with commercial and VRF systems priced after a survey. Most split systems we fit in North Lee are reversible: in heating mode they work as an air-to-air heat pump, which is why many owners use theirs all year.
The outdoor unit position is the biggest single decision: we balance airflow, noise, the pipe run and access for future servicing.
Villages like North Lee often have older houses and cottages, some of them listed. We check that first, because permitted development does not apply within the grounds of a listed building.
Each manufacturer sets its own warranty period. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

Your questions about air conditioning in North Lee
Can I get a fixed-price quote for air conditioning in North Lee?
Start with a short message: the address, what you need and a picture or two. Simple jobs can be priced from pictures; otherwise we arrange a site survey and then give you a fixed-price quote.
Do you cover North Lee for air conditioning?
We do: North Lee falls inside our working area. Tell us a little about the job and we’ll take it from there.
Will I get records for the system?
Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.
Which type of system should I choose?
Number of rooms, space outside and how much of the unit you want to see all decide it. Ducted units need a void or loft, and cassettes need a suspended ceiling, which we check on the survey.
Do you work on commercial properties?
Yes. From a single let flat to offices, shops and public buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
How quickly will you reply?
The same working day. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
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.
What the work involves, system by system
Ceiling cassettes
Ceiling cassettes fit into the ceiling and push air out in several directions and they’re a common choice for offices, shops and larger rooms.
Pipework and condensate drains
Air conditioning takes moisture out of the air when it cools, which the condensate drain takes away. Where it can’t fall naturally to a drain, a condensate pump lifts it, and we plan that on the survey.
What an install looks like in North Lee
About 36 miles out from central London, North Lee is part of the South East area we work across. Census 2021 figures found about 52% of households in terraced houses. Terraces have little side access, so the outdoor unit usually goes on the rear wall or a flat roof, with the pipe run kept short.
Most people start with the room that gets hottest, then add more rooms on a multi-split if needed.

What we do, step by step
Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. The work takes anything from a day for one room to several days for a multi-room or ducted system. A note on how to find the property and where to park makes a visit to North Lee easier.
- 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 needed.
- Checks: a pressure test for leaks, then a vacuum to clear moisture.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Getting ready for the visit
- Plan for pets to be kept clear during the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Tell us about parking and loading
Ask for a quote
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and simple jobs can often be priced without a visit.

Common problems we fix in North Lee
Commercial spaces gain heat from people, equipment, lighting and glazing. Keeping staff and customers comfortable is typically what prompts the call, and some rooms need cooling for the equipment as much as the people.
These are the situations we see most often:
- Fans and portables that don’t keep up
- An office, shop or restaurant that is uncomfortable for staff and customers
- An old system that needs replacing
Homes near Church of St Mary are a good example of where we look up the heritage status of the building before fixing anything to it.
Questions to ask before booking
- Which brand and model they’re proposing, and why
- Whether the price is fixed or an estimate
- If the quote is based on a survey, photos or a diagnosis
What air conditioning won’t do
An honest diagnosis matters more to us than a booking, so here’s what air conditioning won’t do:
- Stuffy rooms that need fresh air rather than cooling
- Damp or condensation caused by leaks or poor ventilation in the building (that needs the cause fixing)
- A building fabric problem such as single glazing or no loft insulation

What a customer said
“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.”
