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.

Getting the right window grille for your building

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.

What the rules say in England

England

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.

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.

Window security grilles in New Malden: questions

Do you cover Surbiton as well as New Malden?

Yes. As well as New Malden, we can arrange surveys in nearby Surbiton, Morden and Wimbledon, and elsewhere in Greater London.

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.

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.
