Retractable security grilles in Finchley

Retractable security grilles in Finchley: what will it cost?

As a guide, retractable security grilles in Finchley cost £414 to £1,554 including VAT (£345 to £1,295 plus 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.

A retractable security grille is a steel or aluminium lattice of vertical bars joined by scissor links that runs in a top and bottom track. Drawn across a window or door it forms a locked barrier; slid back, it folds into a narrow stack at the side so the opening is fully usable.

What goes into a retractable grille

Top-hung or bottom-running versions to suit the floor or sill
Galvanised or powder-coated steel, or aluminium for lighter duty
Single, double or multi-leaf layouts for wide openings
Key-operated lock box on the leading edge, with optional extra locking points
Quick-release internal handle available where a window must stay usable for escape
Folds into a stack typically around a sixth of the opening width

Getting the right retractable grille for your building

Which side it folds to

The stack needs a clear wall or reveal to park against. We check curtains, handles, radiators and light switches before the grille is ordered.

Bottom track or no bottom track

A bottom track gives the most rigid grille but can be a trip point across a doorway. Low-profile and removable floor tracks are available for doors.

What the rules say in England

England

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.

Grilles inside the glass

A grille fitted inside the glass does not normally need planning permission, because it does not materially change how the building looks from outside. If the building is listed, listed building consent may still be needed.

Retractable security grilles in Finchley: questions

Can you survey in Finchley and nearby towns?

Yes. Surveys in Finchley, Muswell Hill, Cricklewood and elsewhere in Greater London are booked around installer availability.

How long does a retractable grille take to fit?

Most single windows or doors are fitted in an hour or two once the made-to-measure grille arrives. A shopfront or several openings may take a day.

Can a retractable grille be fitted inside the window?

Yes, and that is how most are fitted. The tracks fix into the window reveal or to a timber or steel subframe, so the grille sits between the glass and the room.

Do retractable grilles need a bottom track?

Most do, because the bottom track stops the grille being pushed out of line. On doorways a low or recessed track can be used to reduce the trip hazard, and some top-hung designs work without one on smaller openings.
