Air conditioning in Kemsing
Air conditioning in Kemsing, planned around the village rules
Apex fits heat-and-cool air conditioning in Kemsing houses and cottages, about 10 miles from our Dartford base. Parts of the village have extra planning controls, so Olly checks your address before he quotes, then gives you a fixed written price for a system that fits the rules.

Why Kemsing's planning rules matter for air con
Kemsing Conservation Area has an Article 4 direction. That lets Sevenoaks District Council remove some permitted development rights, so work that would be allowed without an application elsewhere may need one here. The village also has more than 30 listed buildings, sits in the Green Belt, and some land to the north is in the Kent Downs National Landscape.
For most houses outside the conservation area, a heat-and-cool split is usually permitted development if the outdoor unit passes the MCS 020(a) noise test of 37 dB(A) at the nearest neighbouring window. Inside it, or for a listed building, we talk to you about an application first. Our air con planning permission guide has the detail.
Air con in Kemsing's newer houses
Most homes in Kemsing are twentieth-century houses to the west and south of the old village. These usually suit a wall-mounted split, with the outdoor unit at the side or rear and a short pipe run.
A bedroom under the roof that stays warm all night, or a living room in the afternoon sun, is a typical place to start, and a second room can join the same outdoor unit later with a multi-split. Read about having air conditioning installed.
Where one of these houses has been extended at the back, a flat-roofed extension or a side return is often the neatest spot for the outdoor unit.
It keeps the pipe run short and the unit out of view from the road. In winter the same system heats the room, which is handy for a cold extension that the radiators never quite reach.
Olly can often tell from photos whether your Kemsing room needs a single or multi split.

A review from Kemsing
Thanks to olly and his team for fitting me a split air conditioning unit back in July, keeping us comfortable in the summer heatwave


Cottages in the old village
The older houses in Kemsing are built of flint, brick and clay tile, and some are timber-framed. Flint and old brick walls change how we drill and seal the pipe route, and we keep the outdoor unit off the front of the house.
Where a wall unit would look wrong in a beamed room, a floor-mounted unit under a window can be a neater choice. It sits low, like a radiator, and blows warm air along the floor in winter, which suits rooms with low ceilings.

Also covering Otford, Heaverham and Seal
From Kemsing we cover Otford, Heaverham, Seal, Shoreham and Sevenoaks. Two of our Checkatrade reviews are for split units fitted in and near Sevenoaks in 2020, and we have since fitted a Daikin three-unit multi system for a house in Sevenoaks. Once a system is in, a yearly service and clean keeps it efficient and protects the warranty.

The best value quote I got, very friendly and professional. Would definitely recommend and wouldn't hesitate to use again
Wonderful Service, Our Air Conditioner was leaking in winter and since then left in very bad condition. Then, Olly did magic and it's now up and running like a new. He did cleaned it thoroughly through low pressure jet and liquid detergent. Tested whole system to identify other faults. He was reasonable in price compared to other service provider. Highly Recommend him for right service and right guidance.
Questions
Air conditioning in Kemsing: questions
Do I need planning permission for air con in Kemsing?
It depends on where you live in the village. Outside the conservation area, a heat-and-cool system on a house is usually permitted development if it meets the size, siting and noise rules. Inside the conservation area, the Article 4 direction may remove some of those rights, and listed buildings always need consent. We check your address before quoting.
What is an Article 4 direction and does it affect air con?
An Article 4 direction is a council order that removes some permitted development rights in a set area, so changes that would normally need no application must go through planning. Kemsing Conservation Area has one. Whether it covers an air conditioning outdoor unit at your house depends on its wording, so we check it with you before planning the job.
Can I put air conditioning in a flint cottage in Kemsing?
Usually, yes. We plan a pipe route that suits flint or old brick walls, seal the hole properly so damp cannot get in, and place the outdoor unit at the rear or side. A floor-mounted indoor unit can sit more naturally in a cottage room than a wall unit. If the cottage is listed, you need listed building consent first.
Do you service air conditioning in Kemsing?
Yes. We service heat-and-cool systems in Kemsing, Otford and Seal, including Daikin, Mitsubishi Electric and Panasonic. Each service includes a filter and coil clean, a drain check, and a check of pressures and controls. Most manufacturers ask for a yearly service to keep an extended warranty valid, so it is worth booking one each spring.
