Air conditioning cost in Surrey
In Surrey, expect roughly £1,500–£3,000 for a single-room split, £3,500–£7,000 for a 3–4 room multi-split, and £6,000–£20,000 for ducted whole-home cooling. South-East prices sit a little above the UK average. Finance can spread the cost into fixed monthly payments.

| Single split (1 room) | £1,500 – £3,000 | 1 indoor + 1 outdoor unit; most bedrooms/offices |
| Multi-split (3–4 rooms) | £3,500 – £7,000 | Several indoor units, one outdoor condenser |
| Ducted whole-home | £6,000 – £20,000 | Concealed, whole-property comfort cooling |
| Annual service | £70 – £120 / unit | Keeps efficiency and warranty intact |

DEMO3.5 kW of heat or cool moved
A modern inverter system moves roughly 3–4 kW of heat for every 1 kW of electricity it draws — it moves heat rather than burning energy to make it.
02 / What moves the price?
Six things that change the number.
More rooms & capacity
Each extra indoor unit adds equipment, pipework and commissioning time — multi-room systems cost more but less per room.
Long pipe runs & access
Awkward condenser positions, long refrigerant runs and scaffold access all add labour to the fixed quote.
Planning & heritage work
Conservation-area or listed-building consent means application work and sometimes more discreet (costlier) siting.
Several rooms at once
One visit, one condenser, shared pipework — a multi-split is cheaper than separate singles installed twice.
Straightforward siting
A ground-floor or easy wall-mount condenser position keeps labour down and usually stays permitted development.
Fixed quote after survey
The free survey removes the unknowns — you get an itemised fixed price, so there are no on-the-day extras.
