Rules that apply in Northern Ireland
Security rules for new homes
If you are building a new home in Northern Ireland, ask the council's building control service which security requirements apply. In existing homes nothing obliges you to upgrade glass, but laminated glass to BS EN 356 P1A in doors and in windows beside them is a common benchmark taken from guidance in Great Britain.
Replacing glass in an existing frame
Building regulations in Northern Ireland are administered by the eleven councils' building control services. Replacing only the glass in an existing frame is generally treated as a repair, while replacing whole windows or doors can be controlled work, so check with building control first. New glass in a critical location should be safety glass under Part V.
Safety glass in critical locations
In Northern Ireland, safety glazing is covered by Part V of the Building Regulations (Northern Ireland) 2012, with guidance in Technical Booklet V. It follows a critical-location approach similar to Great Britain, covering glazing in and beside doors and at low level. Laminated or toughened safety glass is the usual answer; building control at the council can confirm the detail.
Security glazing in Derry: questions

Do you cover Strabane as well as Derry?
Yes. As well as Derry, we can arrange work in nearby Strabane. Dates depend on installer availability.
What is the difference between laminated and toughened glass?
Toughened glass is stronger but breaks into small pieces and leaves an open hole. Laminated glass cracks but stays in the frame, which is why it is the choice for security.
Which security rating do I need?
Homes usually need P1A to P2A under BS EN 356, shops P4A to P6B, and high-value premises P6B to P8B. Your insurer may set the level.
