Getting the right fixed grille for your building

Finish

External grilles last longest when hot-dip galvanised and then powder-coated.

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.

What the rules say in England

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.

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.

Fixed window grilles and bars in Harrow: questions

Do you cover Wembley as well as Harrow?

Yes. As well as Harrow, we can arrange surveys in nearby Wembley, Northolt and Greenford, and elsewhere in Greater London.

Will fixed bars rust?

Galvanised and powder-coated steel is designed for years of outdoor use. Chips in the coating should be touched up to keep the protection intact.

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.
