What to think about first
Colour
White disappears against white frames, while black or anthracite suits darker frames and period sash windows.
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.
Consents and safety: 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 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 Central London: questions
Do you cover Pimlico as well as Central London?
Yes. As well as Central London, we can arrange surveys in nearby Pimlico, Islington and Camden Town, and elsewhere in Greater London.
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.
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.
