What should security secondary glazing cost in King's Lynn?
Our guide range for security secondary glazing in King's Lynn is £594 to £1,794 including VAT (£495 to £1,495 plus VAT) per window, including fitting. The survey is free for new installations and your fixed price follows in writing.
Security secondary glazing is a separate slim window fitted on the room side of an existing window, glazed with laminated glass so it forms a second barrier. It leaves the original window untouched outside, which makes it a common choice for listed buildings, conservation areas and period sash windows.
Glass and fitting options
- Colour-matched frames to suit the room
- Locks and catches that open from inside without a key
- Fixed within the reveal, leaving the original window untouched
- Laminated glass in slim aluminium frames

Before the glass is ordered
Escape and ventilation
On windows used for escape, the secondary glazing must open quickly from inside without a key or tool.
Listed building consent
Internal secondary glazing is usually seen as reversible, but consent can still be needed. Check with the conservation officer first.
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.
Planning permission
Changing the glass in an existing window or shopfront does not usually need planning permission, because the building looks much the same afterwards. A new or altered shopfront, or security features added to the outside of a building, may need planning permission from the council. Bollards or barriers on the pavement need the highway authority's consent, which is normally the council.

Security secondary glazing in King's Lynn: questions
Can you survey in King's Lynn and nearby towns?
Yes. Surveys in King's Lynn, Wisbech and March are booked around installer availability.
Is secondary glazing safe for escape windows?
It can be, as long as it opens quickly from inside without a key. We design catches and handles for that.
Do I need permission for secondary glazing in a listed building?
It depends on the building and the council. Internal secondary glazing usually has less impact than replacement windows, but listed building consent may still be needed. Ask the conservation officer before ordering.
Can I still open my sash windows?
Yes. Secondary glazing slides, hinges or lifts out so the original window can be opened and cleaned.
