Grille lock replacement in Norwich

Grille lock replacement and upgrades in Norwich: what will it cost?

Most grille lock replacements in Norwich cost £150 to £354 including VAT (£125 to £295 plus VAT) per lock fitted. Upgrades such as quick-release or restricted-key cylinders are priced before work goes ahead.

Grille lock replacement means fitting a new cylinder, lock body or complete lock box to an existing security grille. It is the quick fix for lost keys, worn or seized locks and moving into a property with unknown keys, and a chance to upgrade to a stronger or quick-release lock.

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.

Grilles in rented homes

Landlords in England must keep rented homes free from serious hazards under the Housing Health and Safety Rating System, which includes fire. A grille that stops a tenant using an escape window can create a hazard, so grilles in rented homes should have keyless internal releases.
