Air conditioning in Great Bookham
We fit wall-mounted splits, multi-split systems, ducted systems and ceiling cassettes, with VRF for larger buildings. The right choice depends on the rooms, the building and how visible you want the indoor units to be, and we explain the options on the survey. Whether you call it air con, air conditioning or an air-to-air heat pump, it’s the job we do every week across Surrey.
Homes around Great Bookham are mostly houses, many with gardens, which typically leaves room for an outdoor unit. The wall type and how the electrics reach the unit are often the main things to check.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. Keep it with the system’s paperwork, because it helps with any later warranty question.

Air conditioning around Great Bookham
About 48% of homes in and around Great Bookham date from 1945 to 1972, according to VOA council tax data, and the 2021 Census found about 77% of households in detached or semi-detached houses. We check the wall construction on homes of that age, as it decides how the pipework goes through. With homes like that, finding a sensible outdoor unit position is rarely hard, and a multi-split lets two or more rooms run off it.
With historic houses such as Polesden Lacey about 1.6 miles south, it’s a reminder that older homes nearby may be listed, which changes the planning rules. If you commute from Bookham station and work from home on other days, one wall-mounted unit in the home office is often all that is needed.
Great Bookham is about 6 miles south-west of Epsom, in Surrey. Wherever you are in the KT23 postcode area, we cover air conditioning. In Surrey alone we list 395 places, and Great Bookham is one. There’s also a page for Reigate, about 8 miles away.

Great Bookham questions
Will air conditioning in Great Bookham need planning permission?
The answer turns on the property and where the outdoor unit would sit. The Great Bookham Conservation Area is close to the centre of Great Bookham. Permitted development only covers heat pumps that are not used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where needed, we check with the planning department at Mole Valley council, usually the authority for Great Bookham.
Do you cover Great Bookham for air conditioning?
Yes. Great Bookham is one of the places we cover. Get in touch with the details and we reply the same working day.
Will I get records for the system?
Yes. Each visit is written up, including F-Gas records for any refrigerant work. File them with the system’s paperwork.
Can I fit air conditioning or a heat pump myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
How much is air conditioning for one room?
From £1,200 + VAT for a single-room split, with a typical range of £1,200–£2,200 + VAT. The price includes supply, installation, commissioning and F-Gas documentation and is fixed after a survey or from photos.
Do you survey before quoting?
Yes. Every job is looked at first, on a survey, or from your pictures and details where the job is simple. A fixed-price quote follows.
What size air conditioning unit do I need?
It depends on the room, not only its floor area. Glazing, orientation, the roof and what goes on in the room all affect it, and we take them all into account on the survey.
Safe owner checks
Don’t move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. Ask us to quote for a move instead.
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It makes our diagnosis quicker, and a photo of the display helps even more.
Honest limits
In fairness, there are a few things this work won’t fix:
- A lack of fresh air (most split systems recirculate room air rather than bringing fresh air in, which is a job for ventilation)
- Building damp that has a structural cause
- 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)
Not sure which it is? You can phone us on 07833 053749 or write to us at info@aircondoctor.co.uk and we will tell you honestly before booking.
Parts of the system we cover
- Wall-mounted split systems
- Air-to-air heat pumps
- Ducted systems
- Multi-split systems
- Ceiling cassettes
- VRF systems
System by system
Ducted systems
Ducted systems need space for the unit and the ductwork, and access for servicing. The survey confirms whether there’s room.
Ceiling cassettes
Cassettes need space above the ceiling and a route for the condensate, with a condensate pump where the drain cannot fall naturally. The survey confirms the void and the drain route.
What we do, step by step
On the day, we arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. On site, it takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. We load the van from the survey notes so the work in Great Bookham can be done in one go where possible.
- We survey the rooms and the outside of the property, or work from pictures and details for simple jobs.
- Each room is sized and you get a fixed-price quote setting out the equipment and the unit positions.
- The indoor unit is fixed in place, the outside unit positioned, and the connecting runs put in tidily.
- 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
- Mention any managing agent or landlord rules we need to follow
- Let us know if the units are on a roof, a high wall or in a locked area
- Plan for pets to be kept clear during the visit
Getting a quote
Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.

A customer’s words
“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.”
