Air Conditioning Indoor Units — London Homes & Offices
Indoor units come in four common formats: wall-mounted (the workhorse), cassette (recessed into a suspended ceiling), ducted (concealed above a plaster ceiling with a grille) and floor-mounted (below-window installs where a wall unit will not fit). BritOne Air stocks all four formats for the London market. Wall-mounted covers 90% of domestic; cassettes and ducted cover retail and office; floor-mounted picks up the tricky Victorian conversions with limited wall space.

Pay 0% VAT on qualifying home air conditioning installations in London
Qualifying residential air conditioning installations in the UK are eligible for 0% VAT until 31 March 2027, provided the system works as a reverse-cycle air-to-air heat pump supplying both heating and cooling. The relief covers the equipment and the labour when they are bought together, and we apply it automatically on your quote where your installation qualifies.
The installation must be in a domestic building — a house, flat or bungalow that you live in.
A permanently fixed split system or air-to-air heat pump that provides both heating and cooling.
Unit and installation bought together from a VAT-registered contractor. Buying the unit on its own is charged at 20% VAT.
The 0% rate ends on 31 March 2027, after which it reverts to the reduced 5% rate.
- 0% VAT on supply-and-fit residential installations

- Reverts to 5% VAT after 31 March 2027
