Roller security grilles in Derry: what will it cost?
Our guide range for roller security grilles in Derry is £1,495 to £4,995 plus VAT (£1,794 to £5,994 inc VAT) per opening, including fitting. The survey is free for new installations and your fixed price follows in writing.
A roller security grille is a curtain of linked aluminium or steel tubes that coils into a box above the opening. Lowered, it gives an open-mesh barrier you can see through; raised, it leaves the full width clear with nothing parked at the sides.

Getting the right roller grille for your building
Head space
The coil box needs height above the opening. If there is no room inside, a retractable grille is usually a better fit.
Inside or outside
Inside a shopping centre or behind glazing the grille is protected. External roller grilles normally need planning permission.
What the rules say in Northern Ireland
Grilles inside the glass
A grille fitted inside the glass does not normally need planning permission in Northern Ireland, as it does not materially change the outside of the building. If the building is listed, listed building consent may still be needed.
Grilles across exits in business premises
The Fire and Rescue Services (Northern Ireland) Order 2006 and the Fire Safety Regulations (Northern Ireland) 2010 make the appropriate person keep escape routes and exits available and easy to open while people are present. A grille across an exit should be open whenever the premises are occupied.

Roller security grilles in Derry: questions
Do you cover Strabane as well as Derry?
Yes. As well as Derry, we can arrange surveys in nearby Strabane, Limavady and Coleraine, and elsewhere in County Londonderry.
Can a roller grille be fitted inside a shop window?
Yes, where there is enough clear height above the window for the coil and guides. It is a neat option because nothing is left at the sides.
Is a roller grille the same as a roller shutter?
No. A shutter uses solid or perforated slats; a grille uses an open mesh of tubes and links, so you can see through it and air can pass.
Do electric roller grilles need servicing?
Yes. Powered grilles should be inspected and maintained regularly, including the motor, safety devices and manual override, so they stay safe to use.
