How we handle air conditioning in Dallington
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. Air conditioning installation in Dallington starts with a site survey, then a fixed-price quote that names the make and model.
For a home in or near Dallington, an air-to-air system can cool in summer and heat in the cooler months, which suits rooms the main heating doesn’t reach well, such as a garden room or loft.
Nothing is signed off by word of mouth: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual so it’s to hand next time.

What an install looks like in Dallington
About 85% of households live in detached or semi-detached houses, according to the last census (2021). Houses typically have a side or rear wall with room for the outdoor unit, and a multi-split can serve several rooms from one outdoor unit.
Around The Parish Church of St Giles, a quick check of the listing and conservation maps is part of planning any install. Bateman's (roughly 3.1 miles north) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.

What happens if it’s left?
There’s a tax point for homes: installing energy-saving materials in residential accommodation is zero-rated until 31 March 2027, then 5%. Whether a particular system qualifies depends on the facts, so we confirm the VAT on your quote. This is general information, not tax advice. Booking before summer means the work in Dallington is done before the hot weather.
Height, access and the distance between the indoor and outdoor units all affect the cost. Each of those is built into the quote and give you a fixed price before we start.

What else we do in Dallington
Before you call an engineer
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
Different systems, different jobs
Ducted systems
With a ducted system, the indoor unit sits out of sight above the ceiling, with only neat grilles showing in the room. It suits rooms where a visible unit wouldn’t work.
Multi-split systems
A two-room multi-split is typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT. The route from the outdoor unit to each room is the main variable.
Dallington questions
Can I fit air conditioning in Dallington without planning permission?
It comes down to the building and the spot chosen for the outdoor unit. A conservation area takes in the middle of Dallington. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof isn’t allowed under those rules. If there’s any doubt, we ask Rother council, which is typically the planning authority for Dallington.
Is Dallington in your area for air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Dallington is part of that. Tell us a little about the job and we will take it from there.
How do I know what size unit to get?
Floor area is only part of it. Windows, the direction the room faces, the roof above and the people and equipment in it all count, and we take them all into account on the survey.
Do I need to service the system to keep the warranty?
It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so check the terms or ask us. Either way, keep a record of every service.
Who has to arrange F-Gas leak checks?
Responsibility is shared between the operator, normally whoever owns or controls the equipment, and the service technicians. 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.
Do you work on all makes?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and tell you why.
Should I choose wall-mounted, ducted or cassette?
Number of rooms, space outside and how much of the unit you want to see all decide it. Ducted units need a void or loft, and cassettes need a suspended ceiling and the survey confirms what’s possible.
How the visit works
Wherever the system can be run before we leave, we run it and check it in operation. Then we explain what was done and answer your questions, and anything that needs a follow-up is pointed out there and then. All told, the work takes anything from a day for one room to several days for a multi-room or ducted system. Somewhere like Dallington, it helps to know about lanes, gates and where to park.
- We survey the property, or work from your photos for a simple job.
- The system is sized, positions are agreed and the price is fixed.
- Sheets go down first, then the indoor unit and the condenser are mounted.
- Pipework, cable and drain are run, the circuit is connected and the pipework is pressure tested and evacuated.
- We commission, show you the controls and leave the F-Gas and warranty paperwork.
How to prepare
- Unlock any gate, garage or side passage we need
- Make sure someone can let us in at the agreed time
- Tell us about parking and loading
