Air conditioning fitters for London homes.
Split systems, multi-room and concealed installations, surveyed free, quoted fixed, installed in a day by F-Gas certified engineers. Prices published, not hidden.
Seven services, priced in the open
Every price on this site is a guide range you can plan against, and every job is quoted fixed after a free survey. Guide ranges for budgeting, excluding VAT.
Split systems
A wall-mounted unit for one room, installed and commissioned in a day, cooling in summer, efficient heating in winter.
Multi-split
Two to five rooms cooled from one outdoor unit, the whole-home option that keeps the outside of your house tidy.
Ducted systems
Invisible cooling, units hidden in ceiling voids and lofts, with only a slim grille showing. The refurbishment-stage option.
Bedrooms
Quiet units chosen for sleep, 19 to 26 decibels on night mode, sized and sited so you forget they are there.
Flats & apartments
Consent, condenser position and quiet installs, the London flat specialism, from Victorian conversions to new-build towers.
Servicing
Annual servicing that keeps the warranty valid, the air clean and the efficiency where the brochure promised.
Repairs
Diagnosis first, repair with a fixed price second, for systems that trip, drip, blow warm or refuse to start.
What air conditioning actually costs here
A single split system in a London home runs £1,600–£2,600 excluding VAT, supplied and installed in a day. Two rooms from one outdoor unit cost £3,200–£4,800, three rooms £4,800–£7,500, and fully concealed ducted systems start around £7,000. Flats sit a little above houses because the condenser position is harder-won, and anything quoted well under £1,300 is cutting a corner you will pay for later.
The full breakdown, running costs, what moves a quote and where cheap installs go wrong, is on the cost guide and in 40 honest answers across our FAQs.

Bedrooms you can actually sleep in.
A London loft bedroom under slate holds 28°C at midnight in July. The fix is a quiet-specification unit, sized to the room's real heat load, positioned so it never blows across the bed, with the condenser sited away from every bedroom window, including next door's.
- Night-mode sound level quoted in writing before you buy
- Sized from the fabric, not the floor area; roofs decide loft loads
- Condenser siting assessed for night-time noise, yours and your neighbours'
Survey to certificate, one team
Free survey
We size the rooms, walk the condenser positions and pipe routes, and flag any consent your building needs, at your home, no charge.
Fixed quote
A written specification, the exact unit models named, and a fixed price against it. The price we agree is the price you pay.
The install
One day for most installs. Dust sheets, core-drilled and sealed neatly, pipework vacuum-tested before any refrigerant flows.
Handover
Commissioning data, F-Gas paperwork, the manufacturer warranty registered, and a demonstration of the controls before we leave.
