Getting the right internal grille for your building
Access control
Hinged grille doors can take electric locks or readers, wired by a suitable contractor.
Escape routes
Grilles across corridors that are escape routes need careful management and should be shown in your fire risk assessment.
What the rules say in England
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.
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.

Internal security grilles in Derby: questions
Do you cover Belper as well as Derby?
Yes. As well as Derby, we can arrange surveys in nearby Belper, Ilkeston and Heanor, and elsewhere in Derbyshire.
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.
Can you add mesh to stop things being passed through?
Yes. Mesh infill is common on stockroom and dispensary grilles.
