UK fire door regulations, compared by nation

Fire safety law is devolved, so the rules for a fire door change depending on where in the UK the building is. Pick a nation to see what differs — or compare all four side by side.

Where the rule sits	England	Scotland	Wales	Northern Ireland
Building regulations (new work)	Approved Document B	Building (Scotland) Regulations 2004 + Technical Handbooks	Welsh Approved Document B — devolved since 31 Dec 2011	Building Regulations (NI) 2012 + Technical Booklet E
Fire safety law once occupied	Fire Safety Order 2005 + Fire Safety (England) Regulations 2022	Fire (Scotland) Act 2005 + Fire Safety (Scotland) Regulations 2006	Fire Safety Order 2005 (as England) + Building Safety (Wales) Act 2026	Fire and Rescue Services (NI) Order 2006 + Fire Safety Regs (NI) 2010
Who holds the legal duty	Responsible person	Duty holder	Responsible person	Appropriate person
Routine fire-door check intervals	Communal every 3 months, flat entrance every 12 months (buildings over 11 m)	No statutory interval — guidance suggests six-monthly in high-rise homes	No statutory interval	No statutory interval
How fire doors are classified	FD30 / FD60 (BS 476-22) or E / EI classes (EN 13501-2); BS 476 withdrawn from ADB by 2029	Short / medium / long — 30 / 60 / 120-minute fire resistance; integrity E-classes	FD30 / FD30S (BS 476-22) or E30 / E30Sa; BS 476 retained, no withdrawal date	BS 476-22 minutes (20 / 30 / 60) plus European E-classes (Technical Booklet E)

The stand-out difference: Wales is the only UK nation that requires an automatic fire suppression (sprinkler) system in every new home — a duty in force since 1 January 2016. Every figure above is drawn from the four nation guides linked in each summary; always confirm against the current official documents for your building.

Why the rules differ across the UK

Building regulations are fully devolved, and fire safety law is partly devolved. England and Wales share the Regulatory Reform (Fire Safety) Order 2005, but their building regulations have diverged since 2011 — Wales keeps BS 476, requires sprinklers in every new home, and now has its own Building Safety (Wales) Act 2026. Scotland and Northern Ireland each have their own building and fire safety regimes, with their own terminology and their own way of classifying a fire door.

The one duty that looks similar everywhere is maintenance: in every UK nation, fire doors in occupied buildings must be kept in effective working order. What changes is who holds that duty, how often the law expects doors to be checked, and which classification the door is specified to. Use the compliance checker for the specific duties that apply to your building, or see how this divergence built up on the fire door regulation timeline.
