Internal security grilles in Derry: what will it cost?

Budget £595 to £1,995 plus VAT (£714 to £2,394 inc VAT) per opening for internal security grilles in Derry, supplied and fitted. Size, number of leaves, colour and access all move the price, which is fixed in writing after the 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.

Getting the right internal grille for your building

Partition strength

A grille is only as strong as what it is fixed to; stud walls may need reinforcement.

Visibility

Grilles keep areas visible to staff and cameras, unlike solid partitions.

What the rules say in Northern Ireland

Northern Ireland

Listed buildings and conservation areas

Listed buildings in Northern Ireland need listed building consent for works affecting their character, with the council deciding and the Department for Communities' Historic Environment Division advising. Conservation areas bring extra scrutiny of external changes.

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.

Internal security grilles in Derry: questions

Which areas near Derry do you cover?

We can arrange work in Derry and in nearby Strabane (13 miles), Limavady (15 miles) and Coleraine (27 miles). Dates depend on installer availability.

Can grille doors take access control?

Hinged grille doors can be prepared for electric locks or readers, with the wiring done by a suitable installer.

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.
