A fixed window grille is a welded steel frame of bars bolted permanently over or inside a window. It has no moving parts and no lock to pick, which makes it the simplest and most economical grille for openings that are never used for access or escape.

Anti-tamper bolts or resin anchors into masonry
No lock to maintain
Made to measure for arched and odd-shaped openings
Galvanised, powder-coated or both for external use

Typical places for this kind of grille include:

Rear storerooms and plant rooms
Toilet and utility windows
Outbuildings and workshops
Commercial back elevations

Things to decide before you order

Inside or outside

Inside fixing keeps the grille away from weather and tampering. Outside fixing suits windows with no internal access or depth.

Never needed for escape

A fixed grille should only go on a window that is not needed as an escape route. Bedrooms and upstairs habitable rooms usually need an openable alternative.

Rules that apply 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.

External grilles and planning

External grilles and shutters on shops and other commercial buildings normally need planning permission from the local council because they change the building's appearance. Many councils' shopfront guides favour internal, open-lattice grilles, particularly in conservation areas.

Fixed window grilles and bars in Thetford: questions

Can you survey in Thetford and nearby towns?

Yes. Surveys in Thetford, Bury St Edmunds, Diss and elsewhere in Norfolk are booked around installer availability.

Can fixed bars go on a bedroom window?

Generally no. Bedroom and upstairs habitable room windows often need to work as escape windows, so they should have an openable grille with a keyless internal release.

Do fixed grilles need planning permission?

Internal fixed grilles usually do not. External grilles on front elevations, listed buildings or in conservation areas may need consent, so we check before ordering.

Can fixed grilles be removed later?

Yes, by unbolting them from inside, though anti-tamper fixings are deliberately awkward to remove.
