What should security secondary glazing cost in Bristol?
As a guide, allow £594 to £1,794 including VAT (£495 to £1,495 plus VAT) per window for security secondary glazing in Bristol, 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.

- Locks and catches that open from inside without a key

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.
How it opens
Match the opening style to the original window so both can be opened, cleaned and used for ventilation.
Glazing rules in England
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.
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.

Security secondary glazing in Bristol: questions
Which parts in Bristol do you cover?
We can arrange work anywhere in Bristol, including Clifton, Bedminster, Easton, Fishponds and Southville.
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.
