Air Conditioning

Two ways to cool a UK home: a portable unit you plug in yourself, or a split system fixed to the wall by an installer. Compare both by how much room they can cool, what they cost to run and how loud they are, and find the right size for your room.

A fixed split is an air-to-air heat pump Split systems cool in summer and heat efficiently in winter, for a fraction of a portable's running cost. Air-to-air units do not qualify for the £7,500 Boiler Upgrade Scheme grant, which is for air-to-water heat pumps that run your radiators and hot water. Compare grant-eligible heat pumps
