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.

Choices you can make

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

Surrey is mostly suburban and commuter housing, from interwar semis to large detached homes, with busy town centres such as Guildford and Woking.

Typical places for this kind of grille include:

Rear windows facing alleys and gardens
Offices and shops with side or rear windows
Outbuildings, workshops and garages with glazing
Ground-floor and basement windows

Things to decide before you order

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.

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

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 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 Caterham: questions

Can you survey in Caterham and nearby towns?

Yes. Surveys in Caterham, Coulsdon, Purley and elsewhere in Surrey are booked around installer availability.

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.

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.
