How much should I budget for window security grilles in Kent?
Budget £414 to £954 including VAT (£345 to £795 plus VAT) per window for window security grilles in Kent, supplied and fitted. Size, number of leaves, colour and access all move the price, which is fixed in writing after the 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.

What to think about first
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.
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.
Consents and safety: England
Bedroom and escape windows
Approved Document B (fire safety) expects many habitable rooms in houses, especially first-floor rooms, to have an emergency escape window with an unobstructed opening of at least 0.33 m², at least 450 mm high and 450 mm wide, with the bottom of the opening no more than 1,100 mm above the floor. We only fit grilles over escape windows with a release that opens from inside without a key.
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 Kent: questions
Which towns in Kent do you cover?
We can arrange work anywhere in Kent, including Maidstone, Gillingham, Chatham, Tunbridge Wells and Folkestone, and in other towns across the area.
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.
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.
