Security glazing in East Grinstead

Glazing in workplaces

Regulation 14 of the Workplace (Health, Safety and Welfare) Regulations 1992 requires windows and transparent surfaces in walls, partitions, doors and gates to be of safety material or protected against breakage where health or safety makes that necessary, and to be marked so people notice them. The employer or the person in control of the premises decides what is needed through their risk assessment.

Replacing glass in an existing frame

Replacing only the glass or sealed unit in an existing frame is generally treated as a repair in England rather than notifiable building work. Replacing a whole window or door is notifiable and is normally certified through a competent person scheme or approved by building control. Either way, new glass in a critical location should still be safety glass.

Listed buildings and conservation areas

In England, listed building consent from the council may be needed to replace historic glass such as crown or cylinder glass, or to alter glazing bars, sashes and frames. Historic England publishes guidance on traditional windows. Secondary glazing and window film are often easier to agree because they can be removed later, but the council's conservation officer makes the decision.
