Security secondary glazing in Christchurch: what will it cost?
Our guide range for security secondary glazing in Christchurch 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.

- Suits sash, casement and arched openings
- Fixed within the reveal, leaving the original window untouched
- Locks and catches that open from inside without a key
- Vertical sliding, horizontal sliding, hinged and lift-out styles

Getting the right glass for your building
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.
What the rules say 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 Christchurch: questions
Can you survey in Christchurch and nearby towns?
Yes. Surveys in Christchurch, Bournemouth and New Milton are booked around installer availability.
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.
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.
Does secondary glazing reduce noise?
Yes, often noticeably, because of the air gap between the two panes. Laminated glass helps further.
