Lock positioned to clear window handles and restrictors
Fitted inside the glass by default; external options for recessed or plain openings
Quick-release escape handle for bedroom and upstairs windows

Questions we will ask at the survey

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.

Colour

White disappears against white frames, while black or anthracite suits darker frames and period sash windows.

Planning and safety in England

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.

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 Thetford: questions

Do you cover Bury St Edmunds as well as Thetford?

Yes. As well as Thetford, we can arrange surveys in nearby Bury St Edmunds, Diss and Wymondham, and elsewhere in Norfolk.

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.

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.
