An escape window grille is a retractable grille with a release on the inside that opens it without a key or tool. It secures a window against entry from outside while keeping the window usable as an emergency escape route from inside, which bedroom and upstairs windows often need to be.
What goes into a quick-release grille
- Clear opening kept at or above the window's escape size
- Release positioned at a sensible height
- Release positioned so it should not be reachable from outside
- Keyless internal lever or push-button release
- White, black or anthracite finishes
- Can be keyed alike with other grilles for daytime locking

What to think about first
Clear opening
The folded grille must not reduce the window's clear opening below what escape requires.
Release position
Easy to find and operate in the dark, but not something a passer-by can reach.
Consents and safety: England
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.
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.

Escape window grilles (quick release) in Isleworth: questions
Can you survey in Isleworth and nearby towns?
Yes. Surveys in Isleworth, Hounslow, Heston and elsewhere in Greater London are booked around installer availability.
How does a quick-release grille work?
A lever or push release on the inside of the lock box unlatches the grille so it can be slid open in one movement, with no key needed.
Can I lock a quick-release grille when I go away?
Some designs allow a key lock to be used as well, for when the house is empty. The release must always be usable when anyone is sleeping there.
Can I have security grilles on bedroom windows?
Yes, as long as the grille opens from inside without a key or tool. That keeps the window usable as an escape route.
