How much should I budget for retractable security grilles in Northolt?

A retractable security grille is a steel or aluminium lattice of vertical bars joined by scissor links that runs in a top and bottom track. Drawn across a window or door it forms a locked barrier; slid back, it folds into a narrow stack at the side so the opening is fully usable.
What you can specify
- Vertical bars with diagonal scissor links that lock rigid when closed
- White, black and anthracite as standard, other RAL colours to order
- Key-operated lock box on the leading edge, with optional extra locking points
- Top-hung or bottom-running versions to suit the floor or sill
- Folds into a stack typically around a sixth of the opening width
- Galvanised or powder-coated steel, or aluminium for lighter duty

What to think about first
Bottom track or no bottom track
A bottom track gives the most rigid grille but can be a trip point across a doorway. Low-profile and removable floor tracks are available for doors.
Security level
Domestic grilles suit most homes. Shops, pharmacies and high-value stock may justify heavier sections or a third-party certified product.
Consents and safety: 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.

Retractable security grilles in Northolt: questions
Which areas near Northolt do you cover?
We can arrange work in Northolt and in nearby Greenford (1 mile), Harrow (3 miles) and Southall (3 miles). Dates depend on installer availability.
Will a grille stop me opening my windows?
No. An internal grille sits inside the reveal, so you can open the window as normal when the grille is folded back, and usually with it closed if there is enough depth between grille and glass.
Do retractable grilles need a bottom track?
Most do, because the bottom track stops the grille being pushed out of line. On doorways a low or recessed track can be used to reduce the trip hazard, and some top-hung designs work without one on smaller openings.
Can a retractable grille be fitted inside the window?
Yes, and that is how most are fitted. The tracks fix into the window reveal or to a timber or steel subframe, so the grille sits between the glass and the room.
