Air conditioning installation in Tilgate
Most air conditioning needs its own electrical supply from the consumer unit. Under Part P, a new circuit is notifiable unless a registered competent person does it, and our NICEIC approval means we install and certify it ourselves. Looking for air con installers near Tilgate? AirCon Doctor works across London and the South East from East Grinstead, as an F-Gas certified company with NICEIC approval.
Around Tilgate, older cottages and newer houses can be very different to work on. Thick walls, low ceilings and beams need care with pipe routes, and if the home is listed, consent comes before any work.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Why it’s worth doing now in Tilgate
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 earns its keep all year. A dirty or faulty system works harder and costs more to run.
Several rooms, units or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed price.

What an install looks like in Tilgate
About 75% of homes in Tilgate and the neighbourhoods around it date from 1945 to 1972, according to Valuation Office Agency council tax records, and the last census (2021) found about 46% of households in terraced houses. Homes of that age normally have cavity or solid brick walls, and we check which before planning the pipe route. With a terrace, the back wall or an extension roof is usually the best place for the outdoor unit. In the mile around Tilgate’s centre, 6 conservation areas have been designated. None of this rules air conditioning out. It just means the planning position is checked before anyone suggests a spot for the outdoor unit.
Living close to Holy Trinity? Some older properties in parts like that are protected, and the survey finds out whether yours is. Tyes Place (roughly 4.6 miles south) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.

What else we do in Tilgate
Looking after your system
Systems last better with the right care. Here’s what we suggest:
- Choose a comfortable set temperature rather than the lowest
- Tell us if the unit starts to leak, rattle or show a code
- Keep the F-Gas records, commissioning details and warranty information together
The filters are the one part you will look after yourself, so we show you how. Clean them every few weeks when the system is in heavy use, or as the manual recommends, and keep the outdoor unit clear of leaves and clutter.
Book an annual service. A service cleans what you cannot reach and picks up faults before they stop the system and keeps the warranty paperwork right where servicing is a condition.
Your questions about air conditioning in Tilgate
Can you do air conditioning in Tilgate?
Yes. Tilgate is one of the places we cover. Just call us on 07833 053749 or drop us a line with a few details.
Do you cover smaller places like Tilgate?
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.
How does the warranty work?
Warranty is the manufacturer’s own, on its terms. Terms differ by brand, and we set them out on your quote.
How long does air conditioning installation take?
Allow about a day for a single-room system, longer for multi-room and ducted systems. The survey tells us how long your installation will need so there are no surprises.
Is there a survey before the work?
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.
Can you come out in an emergency?
Yes, any time. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we will tell you what to do first.
Do I need planning permission?
Not necessarily. Permitted development can cover a heat pump on a house, including an air-to-air system that heats as well as cools since 2025, provided the conditions are met. Permission is more likely to come up for cooling-only units, listed buildings, flats and road-facing positions in conservation areas and the survey picks it up. This is general information, not legal advice.
The process
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 anything from a day for one room to several days for a multi-room or ducted system. A few photos let us plan a visit to a place like Tilgate.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Next, a recommendation for each room and a fixed price.
- Then the work: units up, pipes and drain run, and a new circuit where needed.
- Before it runs, the pipework is proved tight and put under vacuum.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Preparing for the visit
- Clear the space around the indoor unit, or where it will go
- Plan for pets to be kept clear during the visit
- Let us know where the consumer unit is
