Questions we will ask at the survey
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.

Insurer requirements
Insurers set their own conditions for business premises, stock and cash. If your policy names a type or rating of grille, get the wording in writing before ordering; the insurer decides whether a product meets it.
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 Blackburn: questions
Can you survey in Blackburn and nearby towns?
Yes. Surveys in Blackburn, Darwen, Accrington and elsewhere in Lancashire are booked around installer availability.
Do internal grilles need planning permission?
Generally not, though listed buildings may need consent for internal works.
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 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.
