How much should I budget for security secondary glazing in Whitby?
Our guide range for security secondary glazing in Whitby 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
- Low-E glass for better insulation
- Vertical sliding, horizontal sliding, hinged and lift-out styles
- Locks and catches that open from inside without a key
- Laminated glass in slim aluminium frames
- Fixed within the reveal, leaving the original window untouched
- Suits sash, casement and arched openings

What to think about first
Listed building consent
Internal secondary glazing is usually seen as reversible, but consent can still be needed. Check with the conservation officer first.
How it opens
Match the opening style to the original window so both can be opened, cleaned and used for ventilation.
Consents and safety: England
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.
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 Whitby: questions
Do you cover Scarborough as well as Whitby?
Yes. As well as Whitby, we can arrange work in nearby Scarborough. Dates depend on installer availability.
Can I still open my sash windows?
Yes. Secondary glazing slides, hinges or lifts out so the original window can be opened and cleaned.
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.
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.
