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 you can specify
- Lock positioned to clear window handles and restrictors
- Fitted inside the glass by default; external options for recessed or plain openings
- Powder-coated in white, black or anthracite to sit with the frame colour
- Made to measure for the reveal, including bays and splayed reveals
- Anti-tamper fixings into masonry or a fabricated subframe
- Works with uPVC, aluminium, timber and steel windows

London's buildings range from Victorian and Edwardian terraces and mansion blocks to post-war estates, with long high streets of ground-floor shops below flats.
Typical places for this kind of grille include:
- Outbuildings, workshops and garages with glazing
- Flats with windows onto shared walkways
- Offices and shops with side or rear windows
- Rear windows facing alleys and gardens
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
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 Islington: questions
Which areas near Islington do you cover?
We can arrange work in Islington and in nearby Highbury (1 mile), Holloway (1 mile) and Camden Town (2 miles). Dates depend on installer availability.
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.
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.
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.
