What should security secondary glazing cost in Sutton?
As a guide, allow £594 to £1,794 including VAT (£495 to £1,495 plus VAT) per window for security secondary glazing in Sutton, supplied and fitted. Size, glass makeup, access and frame condition move the price, which is confirmed in writing after the free survey.
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.
Choices you can make
- Colour-matched frames to suit the room
- Vertical sliding, horizontal sliding, hinged and lift-out styles
- Fixed within the reveal, leaving the original window untouched
- Locks and catches that open from inside without a key
- Laminated glass in slim aluminium frames
- Noise and draught reduction

Before the glass is ordered
How it opens
Match the opening style to the original window so both can be opened, cleaned and used for ventilation.
Escape and ventilation
On windows used for escape, the secondary glazing must open quickly from inside without a key or tool.
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.
Windows needed for escape
Approved Document B expects many habitable rooms in houses, particularly upstairs, to have an escape window with a clear opening of at least 0.33 m², at least 450 mm high and 450 mm wide, with the bottom of the opening no more than 1,100 mm above the floor. Changing the glass does not alter that, but locks, secondary glazing and film must not stop the window opening. Laminated glass is hard to break through, so escape always relies on the window opening.

Security secondary glazing in Sutton: questions
Which areas near Sutton do you cover?
We can arrange work in Sutton and in nearby Carshalton (2 miles), Banstead (2 miles) and Ewell (2 miles). Dates depend on installer availability.
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.
Will secondary glazing cause condensation?
A well-fitted unit usually reduces condensation on the inner pane. Some ventilation of the gap may be needed, which we discuss at the survey.
