Glazing rules in England
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.
Safety glass in critical locations
In England, section 5 of Approved Document K treats glazing in doors and in side panels within 300 mm of a door edge, from floor level up to 1,500 mm, and any other glazing below 800 mm, as a critical location. Glass there should break safely, be robust, or be guarded. Laminated or toughened glass meeting BS EN 12600 class 3 is the usual answer, rising to class 2 for door and side-panel panes wider than 900 mm.

Misted unit replacement with laminated glass in Dartford: questions
Can you survey in Dartford and nearby towns?
Yes. Surveys in Dartford, Bexley and Swanley are booked around installer availability.
Does replacing a unit need building regulations approval?
Replacing glass or a sealed unit in an existing frame is generally treated as a repair rather than new building work, across the UK. Replacing the whole window is different and is controlled.
Can misted glass be repaired instead of replaced?
Some services drill and dry units, but the seal stays broken and insulation is not restored. A new unit is the reliable fix.
Do I need a new window frame?
No, if the frame is sound. We replace only the sealed unit.
