UK home air conditioning has shifted from luxury to mainstream; Met Office data shows summer overheating in 80%+ of England's housing stock. For most homes, an inverter-driven split system delivers cooling, heating and dehumidification at £2,000–£8,000 fitted.
Types of home AC
Single split (one room), multi-split (3–5 rooms from one outdoor), ducted (rare in UK retrofit), and portable (avoid; noisy and 2–3x the running cost). For 95% of UK homes, splits are the right answer.
Sizing for a UK home
Roughly 0.15–0.2kW cooling per m². Allow for south-facing rooms, glazing area and how well-insulated the property is. Always get the installer to do a manual J calculation rather than guessing.
Choosing a brand
Premium (Daikin, Mitsubishi Electric, Panasonic) costs 15–25% more, lasts longer and runs quieter. Budget brands (Midea, Hisense) are fine for occasional-use rooms but check UK warranty support.
Installation and aftercare
Use F-Gas registered installers only. Annual filter cleaning and a 2-yearly professional service keep efficiency from drifting and the warranty intact.

Do I need planning permission for home AC?+
Usually no; domestic AC units fit under permitted development as long as the outdoor unit is over 1m from the boundary and not on a wall facing a road in a conservation area.
Will AC heat my home in winter?+
Yes; reverse-cycle splits are functionally heat pumps and deliver heating at 3–5x electric resistance efficiency down to -10°C.
