What is the price of window security grilles in Bishop's Stortford?

Budget £414 to £954 including VAT (£345 to £795 plus VAT) per window for window security grilles in Bishop's Stortford, 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.

This type of grille suits:

Ground-floor and basement windows
Rear windows facing alleys and gardens
Flats with windows onto shared walkways
Offices and shops with side or rear windows

Questions we will ask at the survey

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.

Planning and safety 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.

Grilles in rented homes

Landlords in England must keep rented homes free from serious hazards under the Housing Health and Safety Rating System, which includes fire. A grille that stops a tenant using an escape window can create a hazard, so grilles in rented homes should have keyless internal releases.

Window security grilles in Bishop's Stortford: questions

Can you survey in Bishop's Stortford and nearby towns?

Yes. Surveys in Bishop's Stortford, Harlow, Hoddesdon and elsewhere in Hertfordshire are booked around installer availability.

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.

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.
