Rules that apply in England
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.
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.
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.
Security grilles in Hertfordshire: questions
Do you fit security grilles across Hertfordshire?
We can arrange work anywhere in Hertfordshire, including Watford, Hemel Hempstead, Stevenage, St Albans and Welwyn Garden City, and in other towns across the area.
How much do security grilles cost in Hertfordshire?
As a guide, retractable window grilles cost £345 to £795 plus VAT (£414 to £954 inc VAT), door gates £595 to £1,295 plus VAT (£714 to £1,554 inc VAT) and shopfronts £1,195 to £3,495 plus VAT (£1,434 to £4,194 inc VAT), supplied and fitted. Fixed prices follow a free survey.
Do grilles need planning permission in Hertfordshire?
Usually not for grilles fitted inside the glass. External grilles and shutters on commercial buildings normally need planning permission, and listed buildings may need listed building consent. The rules section on this page has the detail.
Can a grille go across a fire exit?
Only if it never obstructs escape while people are inside, for example by being unlocked and parked open during occupied hours.
Which type of grille do I need?
Retractable for openings used every day, fixed for windows that never open and are not needed for escape, removable for occasional use, hinged or bi-fold where there is no room for a folded stack.
