Planning and safety 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.

Window security grilles in Darwen: questions

Which areas near Darwen do you cover?

We can arrange work in Darwen and in nearby Blackburn (4 miles), Accrington (6 miles) and Chorley (7 miles). Dates depend on installer availability.

Should window grilles go inside or outside?

Inside in most cases. Internal grilles avoid weathering, are harder to attack, keep the outside of the building unchanged and rarely need planning permission. External grilles suit openings with no internal depth.

Can I still open the window with a grille fitted?

With a retractable or removable grille, yes. Many fixed internal grilles also leave room to open the sash or casement behind them.

Do grilles work on bay windows?

Yes. A bay is usually treated as separate grilles for each face, or one grille following the bay on a curved or angled track.
