Start with the number and position of elevations, then add frames, sills, extensions, public routes and ground conditions. The provider must confirm a suitable work-at-height strategy.
Access strategy
HSE guidance gives water-fed poles and cleaning from inside as examples of ways to avoid work at height. A provider still needs to assess the building, ground, weather, tools and task before selecting equipment.
Residential route
Rear glazing, side passages, extensions, roof windows and conservatory sections can change time and access. Count elevations and note obstacles so the initial conversation does not rely on a street-view assumption.
Commercial route
Public pavements, entrances, displays, deliveries and opening times create an operational boundary around the glass. A commercial brief should identify work zones and the time windows a provider may assess.
Scope detail
The word windows can hide several expectations. Agree whether the work covers glass only, frame faces, sills, doors, internal panes, screens or conservatory sections, and how pre-existing defects will be recorded.

Questions
No. HSE says work at height should be avoided where reasonably practicable and gives water-fed poles or cleaning from inside as examples. The correct method still depends on a site-specific assessment.
No. Glass, frames, sills, doors and conservatory sections should be listed separately so the provider can confirm what is included.
No availability or weather rule is claimed here. A competent provider should assess weather, ground conditions, equipment and the specific task before proceeding.
There is no universal interval. Exposure, building use, nearby roads or trees, access, budget and the desired appearance all affect the conversation.
No equipment ownership or reach is claimed. The imagery and content illustrate a route a real provider could verify before launch.
