Window security grilles in St Albans

How much should I budget for window security grilles in St Albans?

As a guide, window security grilles in St Albans cost £414 to £954 including VAT (£345 to £795 plus VAT) per window, supplied and fitted. The exact figure depends on size, type, finish and locking, and is confirmed in writing after the free survey.

A window security grille is a steel barrier fitted across a window so that breaking the glass no longer gives a way in. It can be retractable, fixed or removable, and is most often fitted inside the reveal where it is protected and barely noticed from outside.

Hertfordshire mixes the garden cities of Letchworth and Welwyn, post-war new towns such as Stevenage, and historic centres like St Albans.

Where window security grilles are most often used:

Flats with windows onto shared walkways
Offices and shops with side or rear windows
Ground-floor and basement windows
Outbuildings, workshops and garages with glazing

What to think about first

Depth in the reveal

Tracks need a few centimetres of flat reveal. Where the frame sits flush with the wall, the grille can be fixed to a slim subframe instead.

Colour

White disappears against white frames, while black or anthracite suits darker frames and period sash windows.

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.

Window security grilles in St Albans: questions

Can you survey in St Albans and nearby towns?

Yes. Surveys in St Albans, Harpenden, Hatfield and elsewhere in Hertfordshire are booked around 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.

Will a grille damage my window frame?

No. Grilles fix to the wall reveal or a subframe, not to the window itself, so the frame and its warranty are unaffected.
