What to think about first

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.

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.

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.

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.

Window security grilles in Greater London: questions

Which towns in Greater London do you cover?

We can arrange work anywhere in Greater London, including Central London, Islington, Bexley, Barking and Archway, and in other towns across the area.

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.

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.
