Window security grilles in Bicester

Window security grilles in Bicester: what will it cost?

As a guide, window security grilles in Bicester 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.

Getting the right window grille for your building

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.

What the rules say in England

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.

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 Bicester: questions

Do you cover Oxford as well as Bicester?

Yes. As well as Bicester, we can arrange surveys in nearby Oxford, Banbury and Aylesbury, and elsewhere in Oxfordshire.

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.

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.

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.
