How much do retractable security grilles cost in Central London?
As a guide, retractable security grilles in Central London cost £414 to £1,554 including VAT (£345 to £1,295 plus VAT) per opening, supplied and fitted. The exact figure depends on size, type, finish and locking, and is confirmed in writing after the free survey.
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.
Choices you can make
- Key-operated lock box on the leading edge, with optional extra locking points
- Single, double or multi-leaf layouts for wide openings
- Top-hung or bottom-running versions to suit the floor or sill
- Vertical bars with diagonal scissor links that lock rigid when closed
- Galvanised or powder-coated steel, or aluminium for lighter duty
- White, black and anthracite as standard, other RAL colours to order

Things to decide before you order
Security level
Domestic grilles suit most homes. Shops, pharmacies and high-value stock may justify heavier sections or a third-party certified product.
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.
Rules that apply in England
Grilles inside the glass
A grille fitted inside the glass does not normally need planning permission, because it does not materially change how the building looks from outside. If the building is listed, listed building consent may still be needed.
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.

Retractable security grilles in Central London: questions
Do you cover Pimlico as well as Central London?
Yes. As well as Central London, we can arrange surveys in nearby Pimlico, Islington and Camden Town, and elsewhere in Greater London.
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.
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.
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.
