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
- Works with uPVC, aluminium, timber and steel windows
- Lock positioned to clear window handles and restrictors
- Powder-coated in white, black or anthracite to sit with the frame colour
- Quick-release escape handle for bedroom and upstairs windows
- Fitted inside the glass by default; external options for recessed or plain openings
- Anti-tamper fixings into masonry or a fabricated subframe

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.
Retractable, fixed or removable
Match the grille to how often the window opens. Daily-use windows suit retractable; never-opened windows suit fixed; occasional windows suit removable.
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.
Grilles in rented homes
Landlords in England must keep rented homes free from serious hazards under the Housing Health and Safety Rating System, which includes fire. A grille that stops a tenant using an escape window can create a hazard, so grilles in rented homes should have keyless internal releases.

Window security grilles in Greenwich: questions
Which areas near Greenwich do you cover?
We can arrange work in Greenwich and in nearby Blackheath (1 mile), Canary Wharf (2 miles) and Catford (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.
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.
Do grilles work on bay windows?
Yes. A bay is usually treated as separate grilles for each face, or one grille following the bay on a curved or angled track.
