Bespoke security grilles in Isleworth

Bespoke security grilles in Isleworth: what will it cost?

As a guide, bespoke security grilles in Isleworth cost £474 to £3,594 including VAT (£395 to £2,995 plus VAT) per opening, supplied and fitted. The exact figure depends on size, type, finish and locking, and is confirmed in writing after the free survey.

A bespoke security grille is designed and fabricated for one particular opening, such as an arched window, a curved bay, a very large screen or a period building where a standard grille would look wrong. It is measured on site, drawn up and made to suit.

Getting the right bespoke grille for your building

Consents

Listed buildings and conservation areas may need consent; bespoke designs are often how consent is won.

Lead time

Bespoke grilles take longer than standard ones because each is drawn and made individually.

What the rules say 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.
