Air conditioning in Southwick
The best installations are planned before a single hole is drilled. Each room is assessed for its size, windows, direction and how it’s used, and we agree the unit positions and the route for the pipes, cable and drain, all before the price is fixed. A lot of the calls we get from Southwick are about one room that is too hot to sleep or work in. A single-room split system is often the answer, from £1,200 + VAT.
Getting the size right matters more than the brand: we look at the room’s size, windows, insulation and use before choosing a unit.
Around Southwick, 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.
Warranty periods vary by brand and by product. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

FAQs for Southwick
Is planning permission needed for air conditioning in Southwick?
That depends on the building and where the outdoor unit goes. The Southwick Conservation Area takes in the middle of Southwick. Permitted development only covers heat pumps that aren’t used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where needed, we check with the local planning authority (for Southwick, normally Adur council).
Is Southwick within the area you cover?
Yes. Southwick is within the area we cover across London and the South East. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is air conditioning possible in a flat?
Often, yes, but there are extra steps. You’ll normally need the landlord’s or management company’s consent for the outdoor unit and the pipe route and the lease will say. Permitted development rules for flats are also tighter than for houses, so we point out anything that may need permission on the survey. This is general information, not legal advice.
What warranty do I get?
It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition so it’s worth keeping the service records.
Who is responsible for leak checks?
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.
How quickly will you reply?
On the same working day you contact us. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
Where will you put the outdoor unit?
Wall brackets, ground level and flat roofs are all options, chosen for the pipe route, airflow and access. Noise near bedrooms and boundaries is part of the decision and position can affect planning.
Homes in Southwick and air conditioning
Southwick is within about 1 mile of the coast. Salt air is hard on outdoor units, so we site them out of the worst of the sea wind where we can, and can suggest models with corrosion-protected coils where the manufacturer offers them. The Valuation Office Agency’s council tax figures date about 41% of homes in the Southwick area to the post-war years, 1945 to 1972. Homes of that age normally have cavity or solid brick walls, and we check which before planning the pipe route.
Portslade Manor (roughly 0.8 miles north-east) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on. Plenty of people near Southwick station split the week between the train and a spare room, and that spare room is often the first to get a unit.

The process
Each visit runs to the same pattern: check the plan with you, put the dust sheets down, carry out the job, check the system and talk you through it. The visit itself takes about a day for a single-room system, longer for multi-room and ducted systems. Getting to the outside of the property matters more than parking in a place like Southwick.
- 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.
- It’s switched on, checked and handed over with its records.
How to prepare
- Name a contact who can meet us at the agreed time
- Keep pets out of the rooms we are working in
- Dig out any previous service or F-Gas records

Related advice
For landlords and property managers
Running several properties is easier with one contractor. We work across London and the South East, so a run of properties can go into one programme and kept on a regular cycle.
We also work for facilities teams in offices, schools and public buildings across West Sussex. Work can be phased by floor, zone or building around the people who use them.
What the work involves, system by system
Electrical supply
Most systems need their own circuit from the consumer unit. As NICEIC approved contractors, we install it and issue the certificate, which takes care of the Part P notification.
Outdoor unit positions
On flats and terraced houses, space outside is often the deciding factor. We look at walls, roofs, balconies and yards on the survey and we flag any consent you may need.
What affects the cost of air conditioning
Typical ranges are on our prices page, but every job is priced on its own. What we look at:
- What electrical work the job needs
- The brand, model and parts involved
- What we find on the survey or diagnosis
Putting several jobs into one visit can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
What to send for a quote
When you call or email, it’s useful to have:
- The outside wall, roof or yard where the outdoor unit sits or would go
- The make and model of the system, from the label
- The address and the type of property
VAT is set out clearly on every quote, with the rate that applies to your job. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it in writing rather than guess. To get one, call 07833 053749 or drop us a line.
