How much does misted unit replacement with laminated glass cost in Central London?
Budget £150 to £474 including VAT (£125 to £395 plus VAT) per unit for misted unit replacement with laminated glass in Central London, supplied and fitted. Larger panes, thicker makeups and difficult access cost more; the price is fixed in writing after the survey.
Misted unit replacement means swapping a double-glazed unit whose seal has failed, so moisture has got between the panes, for a new sealed unit. Doing it with a laminated pane turns a routine repair into a security upgrade for little extra cost.

Rules that apply in England
Security rules for new homes
Approved Document Q has applied to new homes in England since 1 October 2015. Easily accessible doors and windows, meaning any part within 2 m vertically of the ground or another accessible surface, should meet PAS 24 or an equivalent, and glazing in doors and in windows within 400 mm of a door should be laminated to at least BS EN 356 P1A. It does not apply when you change the glass in an existing home, although it is a sensible benchmark.
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.

Misted unit replacement with laminated glass in Central London: questions
Can you survey in Central London and nearby towns?
Yes. Surveys in Central London, Pimlico and Islington are booked around installer availability.
Will the new unit match the others?
We match the size, spacer colour and glass as closely as we can, including common obscure patterns.
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.
Why is there condensation between my window panes?
The seal around the unit has failed, letting damp air into the gap. The only lasting fix is a new unit.
