Planning and safety in Northern Ireland

Northern Ireland

Grilles in rented homes

Private landlords in Northern Ireland have fitness and safety duties under the Private Tenancies (Northern Ireland) Order 2006, as amended by the Private Tenancies Act (Northern Ireland) 2022. Grilles over windows a tenant may need for escape should open from inside without a key.

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.
