Security secondary glazing in Greenford: what will it cost?
Our guide range for security secondary glazing in Greenford 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.
What you can specify
- Suits sash, casement and arched openings
- Noise and draught reduction
- Locks and catches that open from inside without a key
- Low-E glass for better insulation
- Fixed within the reveal, leaving the original window untouched
- Vertical sliding, horizontal sliding, hinged and lift-out styles

Greater London has every kind of glazing, from Georgian sashes and Victorian bays in conservation areas to high-street shopfronts, office curtain walling and new-build flats.

- Listed homes and buildings in conservation areas
- Homes on busy roads wanting noise reduction
- Ground-floor flats in converted townhouses
- Offices in historic buildings
Getting the right glass for your building
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.
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 Greenford: questions
Do you cover Northolt as well as Greenford?
Yes. As well as Greenford, we can arrange surveys in nearby Northolt, Southall and Wembley. Dates depend on installer availability.
Does secondary glazing reduce noise?
Yes, often noticeably, because of the air gap between the two panes. Laminated glass helps further.
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.
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.
