When to call us in Slinfold
Many people try a portable unit first. Portables push their warm air out through a hose in the window, so the window cannot close properly and the noisy part of the unit is in the room. A fixed split system puts the compressor outside.
Any of these is worth a proper look:
- A business premises that overheats in summer
- Fans and portables that don’t keep up
- A home office that warms up with screens and equipment
Living close to The Parish Church of St Peter? Some older properties in parts like that are protected, and the survey finds out whether yours is.

Air conditioning in Slinfold
Most air conditioning needs its own electrical supply from the consumer unit. 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. Most enquiries from Slinfold start with one hot room: a bedroom, a home office or a loft conversion. A single-room split system is often the answer, from £1,200 + VAT.
In a village like Slinfold, many homes are older, and some are listed. That matters, because a listed home needs consent and permitted development rules do not apply to it.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

What an install looks like in Slinfold
About 81% of households live in detached or semi-detached houses, according to the 2021 Census. 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.
A loft bedroom or a glazed extension is often the room that prompts the first call.

FAQs for Slinfold
Do I need planning permission for air conditioning in Slinfold?
It depends on the property. Central Slinfold is a short walk from the Slinfold Conservation Area. 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 the planning department at Horsham council, normally the authority for Slinfold.
Will you come out to Slinfold?
We do. Villages and hamlets get the same service as the bigger towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
How do I know what size unit to get?
It depends on the room, not only its floor area. 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.
Does air conditioning need its own electrical supply?
Most systems need their own supply from the consumer unit. 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 install and certify it as part of the job.
What warranty do I get?
The manufacturer’s warranty, on the manufacturer’s terms. Terms differ by brand, and we set them out on your quote.
How long does air conditioning installation take?
Most single-room systems take a day. Multi-room and ducted systems take longer, depending on the pipe routes and access and the quote says how long to expect.
Do you offer emergency call-outs?
Yes. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will agree what happens next.
Let and managed properties
We regularly work with managing agents. Tell us the property, the work and the access arrangements, and we will send a fixed-price quote.
Bigger systems bring extra duties: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.
What air conditioning can’t fix
We’d rather tell you now than sell you work that won’t help, so these are the things it will not cover:
- Damp or condensation caused by leaks or poor ventilation in the building (that needs the cause fixing)
- An installation that needs consent nobody has given yet
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
If you’re not sure, just give us a ring on 07833 053749 or use the quote form and we’ll give you a straight answer.
Parts of the system we cover
- Air-to-air heat pumps

What we do, step by step
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First comes a careful look at the system or the space, then we do the work, and finally we test, record and explain. Most of the time goes on the middle part, and that takes about a day for a single-room system, longer for multi-room and ducted systems. A few photos help us make the most of a visit to Slinfold.
- You send pictures, or we visit and survey the rooms and outside.
- Output, positions and price are settled before anything is booked.
- On the day, dust sheets go down and the indoor and outdoor units are fitted.
- Connections are made, checked for leaks and pulled down to a vacuum.
- We commission, show you the controls and leave the F-Gas and warranty paperwork.
Getting ready for the visit
- Keep pets out of the rooms we are working in
- Name a contact who can meet us at the agreed time
- Let us know if the building has a permit or sign-in process
How to get a quote
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your pictures and details. After that, we send a fixed price before any work starts.
