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.
What goes into a window grille
- Anti-tamper fixings into masonry or a fabricated subframe
- Lock positioned to clear window handles and restrictors
- Made to measure for the reveal, including bays and splayed reveals
- Works with uPVC, aluminium, timber and steel windows
- Fitted inside the glass by default; external options for recessed or plain openings
- Retractable, fixed or removable designs

Things to decide before you order
Colour
White disappears against white frames, while black or anthracite suits darker frames and period sash windows.
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.
Rules that apply in England
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.
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.

Window security grilles in Wiltshire: questions
Which towns in Wiltshire do you cover?
We can arrange work anywhere in Wiltshire, including Swindon, Salisbury, Trowbridge, Chippenham and Calne, and in other towns across the area.
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.
Can I still open the window with a grille fitted?
With a retractable or removable grille, yes. Many fixed internal grilles also leave room to open the sash or casement behind them.
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.
