One property side may still have several working positions.
Show the approach to the gutters and the optional surfaces from the ground. Include steps, gates, narrow spaces, parked vehicles, glazed roofs and overhead cables. A reachable frontage does not establish access to a recessed corner or rear extension. Explain shared permissions and any route through the house.
The HSE guidance on work at height calls for planning and suitable equipment. Vacuum availability does not mean the whole list is automatically reachable. Do not arrange ladders, climb for photographs or stand on a glazed roof to make the work possible.
