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
- Made to measure for the reveal, including bays and splayed reveals
- Quick-release escape handle for bedroom and upstairs windows
- Retractable, fixed or removable designs
- Powder-coated in white, black or anthracite to sit with the frame colour
- Fitted inside the glass by default; external options for recessed or plain openings
- Lock positioned to clear window handles and restrictors

Things to decide before you order
Colour
White disappears against white frames, while black or anthracite suits darker frames and period sash windows.
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
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 Dartford: questions
Do you cover Bexley as well as Dartford?
Yes. As well as Dartford, we can arrange surveys in nearby Bexley, Swanley and Welling, and elsewhere in Kent.
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.
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.
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.
