Air conditioning in Molesey
Most air conditioning needs its own electrical 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 our NICEIC approval means we install and certify it ourselves. A lot of the calls we get from Molesey are about one room that is too hot to sleep or work in. That is usually a single wall-mounted split, from £1,200 + VAT.
A single room takes a day in most homes, while multi-split systems for several rooms can take longer, and we leave the room clean and the controls explained.
In a place like Molesey, the outdoor unit often goes on the ground at the side or rear of the house, where it’s out of sight from the road and easy to service.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

Common questions in Molesey
Do you cover smaller places like Molesey?
Yes, and the size of the place makes no difference to how we work. A few photos and the postcode are enough to get things started.
Is planning permission needed for air conditioning in Molesey?
There’s no single answer: the building and the outdoor unit position decide it. There’s a conservation area, the East Molesey Old Village Conservation Area, close to central Molesey. 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 planning department at Elmbridge council, typically the authority for Molesey when it matters.
How does the warranty work?
The manufacturer’s warranty, on the manufacturer’s terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Do you protect the property while you 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?
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, including supply, installation, commissioning and F-Gas documentation. You get a fixed price before any work starts.
Whose job is it to check the system for leaks?
Responsibility is shared between the operator, usually whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Should I choose wall-mounted, ducted or cassette?
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 and the survey confirms what’s possible.
Why deal with it now?
Fans and portables move warm air around rather than removing it. A fixed system removes the heat to the outside, runs more quietly in the room and can typically heat as well, so it works for you in winter as well. Planning ahead for a job near Molesey means we can arrive with everything needed.
Putting the work off seldom saves money. Faults and wear in a system tend to grow, and a system working harder than it should costs more to run. If you’re unsure, give us a ring on 07833 053749 for straight advice and a fixed price.

Aftercare tips
Systems last better with the right care. We suggest:
- File the paperwork with the manual
- Avoid setting it far colder than you need
- Never run the system with the filters out
If anything isn’t right after we’ve gone, call us on the same number. Let us know what’s happening and any error code and we will help you sort it out.
Don’t ignore small changes. Water from the indoor unit, a new rattle or a code on the display typically means something needs attention and catching it early keeps the repair small.
How the visit works
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. On site, the work takes about a day for a single-room system, longer for multi-room and ducted systems. Seeing the property in photos first helps us plan the trip to Molesey.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- The quote is fixed and shows the equipment, where each unit goes and what’s included.
- On the day, we fit the indoor and outdoor units and run the pipework, cable and condensate drain.
- We connect the supply, pressure test the pipework and evacuate it before the refrigerant is released.
- Last comes the run-up: every mode checked, the controls explained and the paperwork left with you.
How to prepare
- Make sure we can reach the consumer unit or fuse board
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Find the manual or the paperwork for the system, if you have it

What affects the quote in Molesey
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The number of rooms, units or zones
- The type of system, from a single split to a larger system
- How easy the units are to reach
The cost depends on the system and the number of rooms or units, how easy the units are to reach and the parts and time the job needs. We give you a fixed price before work begins, so there are no surprises.
What we need to know
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- 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
- Where the outdoor unit is, or where you’d like it

From one of our customers
“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.”
