How much do retractable security grilles cost in Welwyn Garden City?
As a guide, retractable security grilles in Welwyn Garden City 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.

Things to decide before you order
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.
Rules that apply in 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.
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 Welwyn Garden City: questions
Can you survey in Welwyn Garden City and nearby towns?
Yes. Surveys in Welwyn Garden City, Hatfield, Hertford and elsewhere in Hertfordshire are booked around 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.
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.
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.
