Consents and safety: England
Listed buildings and conservation areas
Listed buildings need listed building consent for works that affect their character, which can include internal grilles and their fixings. In conservation areas, councils look closely at anything fitted to the outside. We recommend speaking to the council's conservation officer before ordering.
Grilles across exits in business premises
In workplaces and other non-domestic premises, including the common parts of blocks of flats and HMOs, the Regulatory Reform (Fire Safety) Order 2005 makes the responsible person keep escape routes and emergency exits available and easy to open while people are present. A grille across an exit should be unlocked and parked open whenever the building is occupied, and covered in the fire risk assessment.
