Window security grilles in Chiswick: what will it cost?
Most window security grilles in Chiswick fall within £414 to £954 including VAT (£345 to £795 plus VAT) per window for supply and fitting. We confirm a fixed price in writing after a free survey, before anything is ordered.
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.

Common openings for window security grilles:
- Flats with windows onto shared walkways
- Ground-floor and basement windows
- Offices and shops with side or rear windows
- Rear windows facing alleys and gardens
Getting the right window grille for your building
Colour
White disappears against white frames, while black or anthracite suits darker frames and period sash windows.
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.
What the rules say 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 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 Chiswick: questions
Do you cover Acton as well as Chiswick?
Yes. As well as Chiswick, we can arrange surveys in nearby Acton, Barnes and Shepherds Bush, 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.
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.
