Window security grilles in Bexley: what will it cost?
Most window security grilles in Bexley 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.

London's buildings range from Victorian and Edwardian terraces and mansion blocks to post-war estates, with long high streets of ground-floor shops below flats.
Common openings for window security grilles:
- Rear windows facing alleys and gardens
- Outbuildings, workshops and garages with glazing
- Offices and shops with side or rear windows
- Ground-floor and basement windows
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
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.
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 Bexley: questions
Do you cover Welling as well as Bexley?
Yes. As well as Bexley, we can arrange surveys in nearby Welling, Dartford and Swanley, and elsewhere in Greater London.
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.
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.
