What permissions does a flat need?
Check your lease first. Most need the freeholder's or management company's written consent for anything fixed to the outside of the building. Planning is also stricter for flats: in England and Wales permitted development allows a smaller outdoor unit on a block of flats and only one unit, so many flat installs need a planning application. We tell you which applies before you commit.
Where can the outdoor unit go?
On a balcony floor on anti-vibration feet, on a bracket on a rear wall, or on a flat roof where the freeholder allows. Balconies are often the simplest and avoid working at height.
How do you work in occupied buildings?
We protect common areas, agree access times with the managing agent, and keep noisy work like core drilling to agreed hours.

Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.
UK middle prices. London and the South East are typically higher and much of the North, Scotland and Wales a little lower; see your area page for a local figure.
