Consents and safety: Northern Ireland
Listed buildings and conservation areas
Listed buildings in Northern Ireland need listed building consent for works affecting their character, with the council deciding and the Department for Communities' Historic Environment Division advising. Conservation areas bring extra scrutiny of external changes.
Grilles across exits in business premises
The Fire and Rescue Services (Northern Ireland) Order 2006 and the Fire Safety Regulations (Northern Ireland) 2010 make the appropriate person keep escape routes and exits available and easy to open while people are present. A grille across an exit should be open whenever the premises are occupied.

Bi-folding security gates in County Londonderry: questions
Which towns in County Londonderry do you cover?
We can arrange work anywhere in County Londonderry, including Coleraine, Derry, Limavady and Magherafelt.
Do bi-fold gates need a floor track?
They need some bottom guidance, which can be a recessed channel or discreet floor pins rather than a raised track.
What is the difference between a bi-fold gate and a retractable grille?
A retractable grille uses a scissor lattice that concertinas; a bi-fold gate uses rigid hinged leaves that fold flat. Bi-folds look more architectural; retractables fold into a narrower stack.
How wide can a bi-fold gate be?
From a single doorway up to several metres, split to fold both ways on wider openings.
