Air con installers in Walton on the Hill
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 as NICEIC approved contractors we can install and certify it as part of the job. A lot of the calls we get from Walton on the Hill are about one room that is too hot to sleep or work in. A single-room split system is often the answer, from £1,200 + VAT.
Space outside is rarely the problem in a place like Walton on the Hill. More often it’s the walls, the electrics and the length of the pipe run that need thinking about.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. It also keeps you on the right side of any warranty terms that ask for servicing.

What we do, step by step
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. 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 a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. A few photos help us make the most of a visit to Walton on the Hill.
- We survey the rooms and the outside of the property, or work from pictures and details for simple jobs.
- Cooling loads are worked out room by room, and the written price names the make, the model and every position.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- We connect the supply, pressure test the pipework and evacuate it before the refrigerant is released.
- The system is commissioned and checked in every mode, and we hand over the controls, F-Gas records and warranty information.
Getting ready for the visit
- Move furniture away from the wall where we’ll be working
- Make sure we can reach the outdoor unit, or where it will go
- Let us know where we can park and unload

What owners can safely do
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.

Your questions about air conditioning in Walton on the Hill
Will you come out to Walton on the Hill?
Yes. Walton on the Hill is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
Do I need planning permission for air conditioning in Walton on the Hill?
There’s no single answer: the building and the outdoor unit position decide it. The centre of Walton on the Hill is in the Walton on the Hill Conservation Area. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask the planning department at Reigate and Banstead council, usually the authority for Walton on the Hill.
Do I need to service the system to keep the warranty?
Each manufacturer decides. If servicing is in the terms, missing one could affect a claim and we will tell you what your brand asks for.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is the law, not just our preference, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
What size air conditioning unit do I need?
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 provide F-Gas records?
Yes, always. 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.
What does F-Gas certified mean?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before booking anyone and we’ll gladly show you ours.
