Getting the right fixed grille for your building
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.
Inside or outside
Inside fixing keeps the grille away from weather and tampering. Outside fixing suits windows with no internal access or depth.
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 Welwyn Garden City: questions
Can you survey in Welwyn Garden City and nearby towns?
Yes. Surveys in Welwyn Garden City, Hatfield, Hertford and elsewhere in Hertfordshire are booked around installer availability.
Can fixed grilles be removed later?
Yes, by unbolting them from inside, though anti-tamper fixings are deliberately awkward to remove.
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.
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.
