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.

What you can specify

Fitted inside the glass by default; external options for recessed or plain openings
Quick-release escape handle for bedroom and upstairs windows
Works with uPVC, aluminium, timber and steel windows
Powder-coated in white, black or anthracite to sit with the frame colour
Lock positioned to clear window handles and restrictors
Retractable, fixed or removable designs

Fitting in Thamesmead and nearby

We arrange surveys and fitting in Thamesmead and across the SE28 postcode district, as well as in nearby Barking (3 miles) and Welling (3 miles). Dates depend on installer availability.

London's buildings range from Victorian and Edwardian terraces and mansion blocks to post-war estates, with long high streets of ground-floor shops below flats.

This type of grille suits:

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

Questions we will ask at the survey

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.

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.

Planning and safety in England

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.

Window security grilles in Thamesmead: questions

Which areas near Thamesmead do you cover?

We can arrange work in Thamesmead and in nearby Barking (3 miles), Welling (3 miles) and Becontree (3 miles). Dates depend on installer availability.

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.

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.

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.
