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 you can specify

Retractable, fixed or removable designs
Made to measure for the reveal, including bays and splayed reveals
Powder-coated in white, black or anthracite to sit with the frame colour
Fitted inside the glass by default; external options for recessed or plain openings
Works with uPVC, aluminium, timber and steel windows
Lock positioned to clear window handles and restrictors

Fitting in Nelson and nearby

We arrange surveys and fitting in Nelson and across the BB9 postcode district, as well as in nearby Colne (2 miles) and Burnley (3 miles). Dates depend on installer availability.

Lancashire is known for stone and red-brick terraces in its mill towns, Victorian seaside resorts such as Blackpool, and historic Lancaster.

Where window security grilles are most often used:

Ground-floor and basement windows
Rear windows facing alleys and gardens
Offices and shops with side or rear windows
Outbuildings, workshops and garages with glazing

What to think about first

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.

Colour

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

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.

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.

Window security grilles in Nelson: questions

Do you cover Colne as well as Nelson?

Yes. As well as Nelson, we can arrange surveys in nearby Colne, Burnley and Accrington, and elsewhere in Lancashire.

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.

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.

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.
