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.

- Top-hung or bottom-running versions to suit the floor or sill

Things to decide before you order
Security level
Domestic grilles suit most homes. Shops, pharmacies and high-value stock may justify heavier sections or a third-party certified product.
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.
Rules that apply in England
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.
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 Watford: questions
Can you survey in Watford and nearby towns?
Yes. Surveys in Watford, Bushey, Rickmansworth and elsewhere in Hertfordshire 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.
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.
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.
