One proposal puts it on a shared wall and leaves permissions unmentioned.
THE YORK FIELD GUIDE / AIR CONDITIONING
Air conditioning installers in York
Where can the outdoor equipment actually go? In a York terrace or flat, that answer can reshape the cooling plan before indoor units are chosen.
START WITH THE PROPERTY
Decide where the outside equipment can live
For a York flat or terrace, establish who owns the external wall and whether a route through shared space is allowed. Sketch the rooms to be cooled only after there is a plausible outdoor position.
BEFORE YOU ACCEPT A QUOTE
See the installation, not only the unit
Indoor equipment photographs do not tell you where pipes, electrical supply or condensate will go. A useful quote marks the exterior location and describes the visible finishes as well as each room's cooling capacity.
ILLUSTRATIVE QUOTE COMPARISON
Can the outside unit go where the drawing says?
Another names the owner approval, pipe route and alternative position if consent fails.
THE DECISION
Resolve the external right before comparing indoor models. If the location changes, request a new drainage and noise plan as well as a revised price.

Describe the room load separately.
Even with an approved external route, glazing, occupancy and ceiling height determine the indoor capacity. Give each room its own brief so a neat route does not drive poor sizing.
