Planning

This unit has an outdoor box, so Class G applies. It heats as well as cools, which clears the condition that catches cooling-only units, but the rest of the answer depends on your building rather than the machine.

Grant

This is an air-to-air heat pump, so £2,500 is available towards it under the Boiler Upgrade Scheme, which took in this kind of unit on 28 April 2026. The grant covers England and Wales, residential property only, and not new builds. You do not apply: your installer claims it and it comes off what you pay. They must hold MCS certification to do so, which is a different scheme from the F-Gas certification an air conditioning firm needs to touch the refrigerant.

What the grant covers, and the certification catch

Work out whether it fits your room

Capacity on a box means nothing without the heat load of the room it is going in. Size the room first, then come back and see whether this unit meets the figure.
