Air conditioning in Seven Dials: the local picture
Seven Dials is within about 1 mile of the coast. Near the sea, outdoor unit position matters more: sheltered from salt-laden wind where possible, on fixings that won’t rust. About 66% of homes in and around Seven Dials were built before 1919, according to Valuation Office Agency council tax records, and Census 2021 figures found about 78% of households live in flats. Older homes often have solid walls, which take longer to core drill, so we plan pipe routes carefully and keep them as discreet as we can. For a flat, we look at balconies, flat roofs and rear walls for the outdoor unit, and the lease often needs checking first.
Royal Pavilion (roughly 0.7 miles south-east) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on. Homes near St Luke's Church Prestonville are a good example of where we look up the heritage status of the building before fixing anything to it.
Seven Dials is about 1 mile west of Brighton, in Brighton and Hove. We cover Seven Dials for air conditioning and across the rest of Brighton and Hove. Seven Dials is one of 30 towns, villages and districts in Brighton and Hove where we work.

Air conditioning in Seven Dials
Most modern split systems run as heat pumps, so they can heat as well as cool. The Energy Saving Trust makes the same point: an air-to-air heat pump is what many people simply call air conditioning, and a well-chosen system can earn its keep all year round. If you want air conditioning in Seven Dials, one call covers the survey, the fixed-price quote, the installation and the F-Gas paperwork.
A single room takes a day in most homes, while multi-split systems for several rooms can take longer, and we leave the room clean and the controls explained.
A cottage and a newer house near Seven Dials are very different jobs. Thick walls, low ceilings and beams need care with pipe routes, and if the home is listed, consent comes before any work.
Aftercare is simple, and most of it is in the manual: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

The process
If the system has to be off for part of the visit, we tell you before any work starts, so you can plan around it. For businesses, we can normally work room by room or zone by zone. On site, it takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Everything the job in Seven Dials needs is worked out beforehand.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Checks: a pressure test for leaks, then a vacuum to clear moisture.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Getting ready for the visit
- Dig out any previous service or F-Gas records
- Mention any roof access, ladders or high-level work
- Unlock any gate, garage or side passage we need
How to get a quote
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. Then you get a fixed price before any work starts.

What the work involves, system by system
Outdoor unit positions
Noise is part of the decision: away from bedroom windows and neighbours’ windows where possible and fitted so vibration doesn’t carry into the building. It can also affect whether planning permission is needed.
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 pipe routes to each room make the biggest difference to the price.

What else we do in Seven Dials
Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Have the system serviced once a year
- File the paperwork with the manual
- Wash or vacuum the filters as the manual describes
Commissioning is the last stage: every mode is tested before we go. Once it’s running properly, we take you through the controls and settings so you know how to get the best from it.
Have the system serviced once a year. A service cleans what you can’t reach and picks up faults before they stop the system, and it keeps any warranty servicing conditions in order.
Seven Dials questions
Can I fit air conditioning in Seven Dials without planning permission?
There’s no single answer: the building and the outdoor unit position decide it. Central Seven Dials is a short walk from the West Hill Conservation Area. Permitted development only covers heat pumps that are not used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where necessary, we check with the local planning authority (for Seven Dials, usually Brighton and Hove council).
Is Seven Dials within the area you cover?
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.
Which accreditations do you hold?
As the law requires for refrigerant work, we’re an F-Gas certified company. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
What does it cost to install air conditioning?
For one room, a split system is typically £1,200–£2,200 + VAT. Two rooms on a multi-split are typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT, with supply, fitting, commissioning and F-Gas documentation included. You get a fixed price before any work starts.
Can you fit air conditioning in a leasehold flat?
It depends on the building and the lease. Balconies, flat roofs and rear walls can all work, subject to consent, and we check the options on the survey. This is general information, not legal advice.
How long will the installation take?
It takes a day or more, depending on the number of rooms, the pipe routes and the access. The survey tells us how long your installation will need so there are no surprises.
Do I need a new electrical circuit?
Most of the time, yes: a dedicated circuit is needed. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and we’re NICEIC approved, so we can install and certify it.
When it’s something else
We won’t sell you work that does not address the problem, so here are the limits:
- Building damp that has a structural cause
- Gas boiler or central heating faults (we do not work on gas boilers)
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
Not sure which it is? You can phone 07833 053749 or email us and we will tell you honestly before booking.

A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
