How much do window security grilles cost in Purley?
As a guide, window security grilles in Purley cost £414 to £954 including VAT (£345 to £795 plus VAT) per window, supplied and fitted. The exact figure depends on size, type, finish and locking, and is confirmed in writing after the free survey.
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.
Typical places for this kind of grille include:
- Ground-floor and basement windows
- Offices and shops with side or rear windows
- Rear windows facing alleys and gardens
- Flats with windows onto shared walkways
Things to decide before you order
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.
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.
Rules that apply 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 Purley: questions
Can you survey in Purley and nearby towns?
Yes. Surveys in Purley, Coulsdon, South Croydon and elsewhere in Greater London are booked around installer availability.
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.
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.
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.
