Retractable security grilles in Harpenden

Retractable security grilles in Harpenden: what will it cost?

Budget £414 to £1,554 including VAT (£345 to £1,295 plus VAT) per opening for retractable security grilles in Harpenden, supplied and fitted. Size, number of leaves, colour and access all move the price, which is fixed in writing after the 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.

Key-operated lock box on the leading edge, with optional extra locking points

Getting the right retractable grille for your building

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.

Inside or outside the glass

Inside is the norm: it is protected from weather, keeps the street view unchanged and usually avoids planning issues. Outside fitting suits recessed doorways and openings with no internal depth.

What the rules say in England

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.

Listed buildings and conservation areas

Listed buildings need listed building consent for works that affect their character, which can include internal grilles and their fixings. In conservation areas, councils look closely at anything fitted to the outside. We recommend speaking to the council's conservation officer before ordering.

Retractable security grilles in Harpenden: questions

Which areas near Harpenden do you cover?

We can arrange work in Harpenden and in nearby St Albans (5 miles), Luton (5 miles) and Hemel Hempstead (6 miles). Dates depend on installer availability.

How long does a retractable grille take to fit?

Most single windows or doors are fitted in an hour or two once the made-to-measure grille arrives. A shopfront or several openings may take a day.

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.
