A window security grille is a steel barrier fitted across a window so that breaking the glass no longer gives a way in. It can be retractable, fixed or removable, and is most often fitted inside the reveal where it is protected and barely noticed from outside.

Things to decide before you order
Escape requirements
If the window is a designated escape window, the grille must open from inside without a key or tool. We fit quick-release locks for these.
Depth in the reveal
Tracks need a few centimetres of flat reveal. Where the frame sits flush with the wall, the grille can be fixed to a slim subframe instead.
Rules that apply in 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.

Window security grilles in Northamptonshire: questions
Which towns in Northamptonshire do you cover?
We can arrange work anywhere in Northamptonshire, including Northampton, Corby, Kettering, Wellingborough and Rushden, and in other towns across the area.
Are window grilles safe in a bedroom?
They can be, provided the grille has a release that opens from inside without a key. Bedroom and upstairs windows often have to serve as escape routes, so we will not fit a key-only grille over a window you need for escape.
Should window grilles go inside or outside?
Inside in most cases. Internal grilles avoid weathering, are harder to attack, keep the outside of the building unchanged and rarely need planning permission. External grilles suit openings with no internal depth.
Will a grille damage my window frame?
No. Grilles fix to the wall reveal or a subframe, not to the window itself, so the frame and its warranty are unaffected.
