What does it cost to run?
Most modern split units are heat pumps that both cool and heat. A typical 3.5kW unit draws around 1kW when running — about 25p an hour on a standard electricity tariff, or roughly £2 a day at 8 hours' use. Because running cost is driven by your electricity rate, it pays to be on a cheap tariff. Compare electricity tariffs →
Types of air conditioning
- Split system — one outdoor unit + one indoor wall unit. Quiet, efficient, the most common home choice.
- Multi-split — one outdoor unit feeding several indoor units, room by room.
- Portable — plug-in, no installation, but noisier and less efficient.
- Air-to-air heat pump — a split unit used for winter heating too, often cheaper to run than gas for a single room.
Frequently asked questions
Do I need planning permission for air conditioning?
For most homes, no — a single external unit usually falls under permitted development, but size and siting rules apply, and flats, listed buildings and conservation areas can differ. Your installer will advise.
How long does installation take?
A single split unit is typically fitted in half a day to a day. Multi-room systems take longer, and summer demand stretches lead times — book early.
Can air conditioning heat my home in winter?
Yes — most modern units are reversible air-source heat pumps, so the same system warms rooms in winter, often more cheaply than electric heaters.
Will it push up my electricity bill?
Running costs depend on usage and your electricity rate. Being on a competitive tariff makes a real difference — compare tariffs here.
