Air conditioning in Lewknor, done properly
A new system normally needs a dedicated circuit from the fuse board. 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. Modern air conditioning heats as well as cools: in heating mode they work as an air-to-air heat pump, so a system bought for summer earns its keep in winter too.
Villages like Lewknor often have older houses and cottages, some of them listed. We check that first, because permitted development doesn’t apply within the grounds of a listed building.
We’re an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Signs you need air conditioning in Lewknor
Computers, screens, lighting and people all give off heat. A home office with a couple of screens, or a meeting room with a few people in it, warms up quickly, even on a mild day.
It’s time to call us if you are dealing with:
- A study or office that overheats during the day
- An office, shop or restaurant that’s uncomfortable for staff and customers
- An old system that needs replacing
Adwell House, about 1.6 miles north-west, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.
Questions to ask before booking
- What’s in the price and what is not
- What records you get at the end
- Whether a new circuit is included and who certifies it
When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Central heating repairs
- Building damp that has a structural cause
- A room that cannot 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 ring 07833 053749 or use the quote form and we’ll tell you honestly before booking.

Air conditioning in Lewknor: local notes
The centre of Lewknor lies within the Lewknor Conservation Area. On the National Heritage List, around 18 entries fall within 0.5 miles of the middle of Lewknor; Church of St Margaret (grade I) is one. Before any outdoor unit is fixed here, we find out whether the building is protected. Where it is, the planning team at South Oxfordshire council, which usually handles Lewknor has the final say on what’s allowed. About 36% of homes across Lewknor and its surrounding area were built before 1919, according to Valuation Office Agency council tax records, and about 78% of households live in detached or semi-detached houses, according to Census 2021 figures. Older homes often have solid walls, which take longer to core drill, so we plan pipe routes carefully and keep them as discreet as we can. A side passage or back wall normally gives the outdoor unit a home, and more than one bedroom can be cooled through a multi-split.
If your home is in one of the older streets near Church of St Margaret, it’s worth checking whether it’s listed or in a conservation area before an install.

What happens on the day
Each visit runs to the same pattern: agree the plan on site, put the dust sheets down, do the work, test what we’ve done and explain it all to you. The visit itself takes anything from a day for one room to several days for a multi-room or ducted system. For a place like Lewknor, the timing is set with you and the travel is our side of the planning.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
How to prepare
- Make sure someone can let us in at the agreed time
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Mention any managing agent or landlord rules we need to follow
Getting a quote
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and simple jobs can often be priced without a visit.

Why deal with it now?
Planning ahead beats a rushed decision in a heatwave. A rushed choice is often the wrong size or in the wrong place, and that’s hard to put right later. A survey now gives time to choose properly. An early booking makes the visit to Lewknor easier to arrange.
Typical ranges are on our prices page, but your price depends on the job in front of us. Call for a fixed-price quote, and we’ll talk you through it.

Lewknor: your questions answered
Do you cover smaller places like Lewknor?
Yes. Lewknor is within the area we cover across London and the South East. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is Lewknor in your area for air conditioning?
Yes. Lewknor is one of the places we cover. To start, call us on 07833 053749 or fill in the contact form with a few pictures.
How long will the installation take?
Most single-room systems take a day. Multi-split, ducted and cassette systems take longer, and we tell you how long on the quote.
Can I do the refrigerant work myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey tells us what the job needs and how to do it and the fixed price is built on it.
Should I choose wall-mounted, ducted or cassette?
It depends on the rooms and the building. A split suits one room, a multi-split several, a ducted system hides the unit, and a cassette spreads air across larger rooms. The survey ends with a recommendation and the reasons.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
A customer’s words
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
