How much do internal security grilles cost in Norfolk?
As a guide, internal security grilles in Norfolk cost £595 to £1,995 plus VAT (£714 to £2,394 inc VAT) per opening, supplied and fitted. The exact figure depends on size, type, finish and locking, and is confirmed in writing after the free survey.
Internal security grilles divide a building into zones. Fitted across corridors, stockroom doors, cash offices and server rooms, they keep valuable areas locked off from the rest of the building after hours, or from visitors and staff who do not need access during the day.

Things to decide before you order
Escape routes
Grilles across corridors that are escape routes need careful management and should be shown in your fire risk assessment.
Access control
Hinged grille doors can take electric locks or readers, wired by a suitable contractor.
Rules that apply 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 Norfolk: questions
Which towns in Norfolk do you cover?
We can arrange work anywhere in Norfolk, including Norwich, Great Yarmouth, King's Lynn, Thetford and Dereham, and in other towns across the area.
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.
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.
