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.

Choices you can make

Vertical bars with diagonal scissor links that lock rigid when closed
Folds into a stack typically around a sixth of the opening width
Top-hung or bottom-running versions to suit the floor or sill
Key-operated lock box on the leading edge, with optional extra locking points
Galvanised or powder-coated steel, or aluminium for lighter duty
Quick-release internal handle available where a window must stay usable for escape

Getting the right retractable grille for your building

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.

What the rules say in England

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.

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 Northampton: questions

Do you cover Wellingborough as well as Northampton?

Yes. As well as Northampton, we can arrange surveys in nearby Wellingborough, Daventry and Rushden, and elsewhere in Northamptonshire.

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.

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.

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.
