Rules for window and glass graphics in Welwyn Garden City
Window graphics are something councils treat in different ways. Graphics applied inside the glass are often outside advertisement control or allowed without an application, but large graphics on a listed shopfront or in a conservation area can be restricted, so we check first. Manifestation is a separate matter of safety rather than advertising: glazing that people could walk into must be made visible. In England, Approved Document K suggests marking two zones, 850–1000 mm and 1400–1600 mm above floor level, and the Workplace (Health, Safety and Welfare) Regulations 1992, regulation 14, require transparent surfaces to be marked where necessary for safety.
