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 to think about first

Security level

Domestic grilles suit most homes. Shops, pharmacies and high-value stock may justify heavier sections or a third-party certified product.

Inside or outside the glass

Inside is the norm: it is protected from weather, keeps the street view unchanged and usually avoids planning issues. Outside fitting suits recessed doorways and openings with no internal depth.

External grilles and planning

External grilles and shutters on shops and other commercial buildings normally need planning permission from the local council because they change the building's appearance. Many councils' shopfront guides favour internal, open-lattice grilles, particularly in conservation areas.

Bedroom and escape windows

Approved Document B (fire safety) expects many habitable rooms in houses, especially first-floor rooms, to have an emergency escape window with an unobstructed opening of at least 0.33 m², at least 450 mm high and 450 mm wide, with the bottom of the opening no more than 1,100 mm above the floor. We only fit grilles over escape windows with a release that opens from inside without a key.

Retractable security grilles in Canterbury: questions

Do you cover Whitstable as well as Canterbury?

Yes. As well as Canterbury, we can arrange surveys in nearby Whitstable, Herne Bay and Faversham, and elsewhere in Kent.

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.

Will a grille stop me opening my windows?

No. An internal grille sits inside the reveal, so you can open the window as normal when the grille is folded back, and usually with it closed if there is enough depth between grille and glass.
