Window security grilles in Chelmsford

What is the price of window security grilles in Chelmsford?

As a guide, window security grilles in Chelmsford 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.

Questions we will ask at the survey

Colour

White disappears against white frames, while black or anthracite suits darker frames and period sash windows.

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

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 Chelmsford: questions

Can you survey in Chelmsford and nearby towns?

Yes. Surveys in Chelmsford, Billericay, Witham and elsewhere in Essex 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.

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.

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.
