How much should I budget for grille lock replacement in Harrow?
Most grille lock replacements in Harrow 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.

Consents and safety: England
Grilles across exits in business premises
In workplaces and other non-domestic premises, including the common parts of blocks of flats and HMOs, the Regulatory Reform (Fire Safety) Order 2005 makes the responsible person keep escape routes and emergency exits available and easy to open while people are present. A grille across an exit should be unlocked and parked open whenever the building is occupied, and covered in the fire risk assessment.
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.

Grille lock replacement and upgrades in Harrow: questions
Can you visit addresses near Harrow?
We can arrange work in Harrow and in nearby Wembley (2 miles), Northolt (3 miles) and Greenford (4 miles). Dates depend on engineer availability.
Is a better cylinder worth it?
On a grille that is otherwise sound, a higher-security cylinder is an inexpensive way to raise resistance to lock attack.
Can a key-only grille be converted to quick release?
Often, yes, by fitting a lock with a keyless internal release. We check the grille first.
Can you change a lock on a grille you did not fit?
Yes, on most makes, subject to compatible parts.
