Window security grilles in Cardiff: what will it cost?

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.

Getting the right window grille for your building

Colour

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

Escape requirements

If the window is a designated escape window, the grille must open from inside without a key or tool. We fit quick-release locks for these.

What the rules say in Wales

Wales

Bedroom and escape windows

Wales has its own Approved Documents under the Building Regulations. Approved Document B for Wales sets out escape window provisions for dwellings broadly in line with England's, including minimum opening sizes. We only fit grilles over escape windows with a keyless internal release.

Listed buildings and conservation areas

Listed buildings in Wales need listed building consent for works affecting their character, decided by the local planning authority with Cadw's involvement where required. Conservation areas bring extra scrutiny of external changes. Check with the council before ordering.

Window security grilles in Cardiff: questions

Can you survey in Cardiff and nearby towns?

Yes. Surveys in Cardiff, Penarth, Caerphilly and elsewhere in South Glamorgan are booked around installer availability.

Do grilles work on bay windows?

Yes. A bay is usually treated as separate grilles for each face, or one grille following the bay on a curved or angled track.

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.

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.
