Rules that apply 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.
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.
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 glazing in Hertfordshire: questions
Do you fit security glass across Hertfordshire?
We can arrange work anywhere in Hertfordshire, including Watford, Hemel Hempstead, Stevenage, St Albans and Welwyn Garden City, and in other towns across the area.
How much does security glass cost in Hertfordshire?
As a guide, laminated security glass costs £145 to £495 plus VAT (£174 to £594 inc VAT) per pane, anti-bandit glass £450 to £2,995 plus VAT (£540 to £3,594 inc VAT) per pane and security film £45 to £110 plus VAT (£54 to £132 inc VAT) per m², supplied and fitted. Fixed prices follow a free survey.
Do I need permission to replace glass in Hertfordshire?
Replacing glass in an existing frame is usually treated as a repair rather than notifiable building work, but new glass in a critical location (doors, side panels and low-level glazing) should be safety glass under Approved Document K. Listed buildings may need listed building consent. The rules section on this page has the detail.
Do your prices include VAT?
Prices for homes are shown including VAT, with the ex-VAT figure alongside; prices for business services are shown excluding VAT. The prices page shows both.
Can security glass replace fire-rated glass?
No. Glass in fire doors and fire screens must be fire-rated and tested in that system. Security glass is not a substitute.
