Choices you can make

Made to measure for the reveal, including bays and splayed reveals
Retractable, fixed or removable designs
Quick-release escape handle for bedroom and upstairs windows
Works with uPVC, aluminium, timber and steel windows
Fitted inside the glass by default; external options for recessed or plain openings
Anti-tamper fixings into masonry or a fabricated subframe

Offices and shops with side or rear windows
Rear windows facing alleys and gardens
Flats with windows onto shared walkways
Outbuildings, workshops and garages with glazing

What to think about first

Retractable, fixed or removable

Match the grille to how often the window opens. Daily-use windows suit retractable; never-opened windows suit fixed; occasional windows suit removable.

Colour

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

Grilles in rented homes

Landlords in England must keep rented homes free from serious hazards under the Housing Health and Safety Rating System, which includes fire. A grille that stops a tenant using an escape window can create a hazard, so grilles in rented homes should have keyless internal releases.

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 Potters Bar: questions

Can you survey in Potters Bar and nearby towns?

Yes. Surveys in Potters Bar, Barnet, Enfield and elsewhere in Hertfordshire are booked around installer availability.

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.

Are window grilles safe in a bedroom?

They can be, provided the grille has a release that opens from inside without a key. Bedroom and upstairs windows often have to serve as escape routes, so we will not fit a key-only grille over a window you need for escape.

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.
