Air conditioning in Brighton: get a fixed-price quote

Air conditioning installation in Brighton

Brighton gets plenty of sun, and its tall Regency and Victorian houses, top-floor flats and glass-fronted shops can trap a lot of it. We install, service and repair air conditioning across Brighton and Hove, from a single wall-mounted unit in a bedroom or home office to multi-split systems for a whole house and commercial systems for offices, cafés, shops and hotels.

We’re based in East Grinstead, West Sussex, and we work across the city and the rest of Sussex. We’re an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We fit leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba and LG, and we explain the manufacturer’s warranty for your chosen unit on the quote.

The process is simple. We look at the property on a site survey, or from photos and measurements for straightforward jobs. You get a fixed-price quote. We do the work, then commission the system, record the refrigerant details for your F-Gas records and show you how to use it. A single-room split system is typically £1,200–£2,200 + VAT, and a two-room multi-split £2,800–£4,500 + VAT. Our guide to air conditioning costs in Brighton explains what moves the price.

If your existing system has stopped cooling, we repair all makes, with diagnosis from £75 + VAT. Regular servicing matters more than usual near the sea, as the next section explains.

Not sure what you need yet? Tell us which rooms get too hot, which way they face and what kind of building you’re in, and we’ll suggest a sensible starting point before the survey.

Sea air, tall houses and outdoor units

Salt in the air is hard on outdoor units. It settles on the aluminium fins and copper pipes of the outdoor coil, and over time it can corrode them. Close to the seafront, that wear happens faster than it does inland. Several manufacturers offer coil coatings or models built for coastal sites, and their installation manuals give guidance on where to put units near the sea. We take that into account when we choose the unit and its position, often a sheltered side of the building rather than one facing straight into the wind off the Channel.

Maintenance makes the biggest difference. Rinsing salt and grime off the outdoor coil, checking the fins and fixings, and looking for early signs of corrosion are all part of our service visit. For a property near the front, a yearly service is a sensible minimum. Our guide to protecting air conditioning from salt air goes further.

Brighton’s housing brings its own puzzles. Many houses are tall and narrow, split into flats, with the best spot for an outdoor unit on a rear wall, a flat roof or a basement area. Pipework may need to rise several floors, and every manufacturer sets limits on length and height between the indoor and outdoor units, so we plan the route before quoting. In basement flats, getting condensate water away can mean a small condensate pump.

Modern blocks near the marina and the city centre often have balconies, but many leases and building managers control what goes on them. Newer buildings may also have rules about fixings to cladding. We’ll look at what your building allows and work with your managing agent where needed.

Most split systems also heat. The Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning, and in a draughty period house a unit in heat mode can be a useful top-up in spring and autumn.

Sizing is worth getting right in Brighton’s big bay-fronted rooms and glazed extensions. An undersized unit runs flat out and still struggles; an oversized one switches on and off and wastes energy. We measure each room, note the windows and which way they face, and size the unit to suit.

A recent job in Brighton

New Road, Brighton (BN1)

Property
A boutique hotel with 22 en-suite rooms.
Work carried out
Installation of individual wall-mounted Panasonic units in all 22 guest rooms, plus two cassette units in the restaurant and a dedicated unit for the server room at basement level. The hotel is in a Grade II listed building on the edge of the Royal Pavilion estate, requiring careful external pipework management and a pre-application discussion with the local planning authority. All 25 units were installed across four overnight sessions to avoid any disruption to guests.
Outcome
Guest satisfaction scores relating to room comfort improved significantly in the first summer of operation. The hotel manager reported that the system had paid for itself within 18 months through improved occupancy during hot weather periods.

Conservation areas and planning in Brighton and Hove

Planning across the city is handled by Brighton & Hove City Council. The city has a large number of conservation areas, including Brunswick Town in Hove and East Cliff in Kemp Town, and many listed buildings. The council publishes a conservation areas street directory so you can check your road. Some areas also have Article 4 directions, which remove certain permitted development rights.

For houses outside those restrictions, an air source heat pump can be permitted development if it meets set limits. The Planning Portal’s heat pump guidance explains them: an outdoor unit of no more than 1.5 m³, compliance with MCS 020(a), not used solely for cooling, not on a pitched roof, and extra limits on walls facing the road in conservation areas. Flats have tighter limits. A cooling-only air conditioning unit isn’t covered, so it needs the council’s view. Listed building consent is separate. We’ll give you our view on the survey, but the council decides.

In a conservation area, the visual side matters as much as the rules. A white box on a stuccoed Regency front is rarely acceptable. We look for rear or side positions, keep pipework hidden or in painted trunking, and choose indoor units that suit the room. Our guide to listed buildings covers the extra steps for listed properties.

If you own a leasehold flat, check your lease before anything goes on an outside wall or a shared roof. Most need the landlord’s written consent, and we can provide the specification, photos and proposed positions to support that request. The new electrical circuit is notifiable under Part P; as an NICEIC approved company we self-certify it, as the Planning Portal explains.

Hove and the outer suburbs, such as Patcham, Rottingdean and Woodingdean, have more semis and detached houses, where a side or rear wall often gives an easy spot for the outdoor unit. Even there, check whether your road sits in one of the city’s conservation areas before you assume permitted development applies.

Air conditioning for Brighton businesses

Brighton’s cafés, restaurants, shops, offices and hotels see busy summers, and a hot dining room or changing room costs trade. We install and maintain commercial air conditioning across the city, including ceiling cassettes for open-plan spaces, ducted systems where you want the units out of sight and VRF for larger buildings. See also our pages on restaurants, hotels and retail.

Business systems come with duties: leak checks for systems above the F-gas thresholds, records of every refrigerant top-up, and TM44 inspections for systems over 12 kW. A maintenance contract keeps them on schedule and protects coastal units from early wear.

Seafront and Lanes premises often have little outside space and neighbours on every side. We look at rear yards, flat roofs and internal routes for pipework, and we plan for noise at night when the street goes quiet. For small shops and cafés, one or two wall-mounted or cassette units are often enough; for a larger venue, we design a system around the space and how it’s used.

How it works

  1. Diagnose. We look at the rooms or building on a site survey, or from your photos for simple jobs, and work out what size and type of system it needs.
  2. Quote. You get a fixed-price quote with the make and model of every unit, the pipe runs, electrics and condensate route, and the VAT.
  3. Treat. An F-Gas certified engineer installs, repairs or services the system, with any new circuit done by our NICEIC approved electricians.
  4. Sign off. We commission and leak-test the system, keep the F-Gas records, explain the controls and go through the manufacturer’s warranty terms for your brand.

Questions from Brighton

Does sea air damage air conditioning?

It can speed up corrosion on the outdoor coil, especially close to the seafront. Careful positioning, a suitable unit and regular cleaning on a yearly service all help.

Can I have air conditioning in a Brighton conservation area?

Often, yes, but the rules are tighter. Outdoor units usually need to go on the rear or side, out of view from the road, and cooling-only units need the council’s view. We’ll advise on the survey.

I live in a flat in Hove. Do I need permission?

Usually from two places: your landlord under the lease, and possibly the council. We can give you the details both will ask for.

How much does air conditioning cost in Brighton?

A single-room split system is typically £1,200–£2,200 + VAT, supplied and fitted. You get a fixed-price quote after the survey.

Do you service units that someone else fitted?

Yes. We service and repair all the main brands, whoever installed them, and we update your F-Gas records.

When will I hear back?

We reply to enquiries the same working day. For a breakdown, call our 24/7 line on 07833 053749.
