Getting the right internal grille for your building
Escape routes
Grilles across corridors that are escape routes need careful management and should be shown in your fire risk assessment.
Partition strength
A grille is only as strong as what it is fixed to; stud walls may need reinforcement.
What the rules say in 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.

Internal security grilles in Dereham: questions
Can you survey in Dereham and nearby towns?
Yes. Surveys in Dereham, Wymondham, Norwich and elsewhere in Norfolk are booked around installer availability.
Do internal grilles need planning permission?
Generally not, though listed buildings may need consent for internal works.
Can internal grilles be fixed to stud walls?
Yes, with reinforcement such as a steel subframe or timber noggins, because a grille is only as strong as its fixings.
Can an internal grille go across a corridor?
Yes, but if the corridor is an escape route the grille must be open whenever people are in the building.
