Window security grilles in Lisburn

Window security grilles in Lisburn: what will it cost?

As a guide, window security grilles in Lisburn 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.

Getting the right window grille for your building

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.

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.

What the rules say in Northern Ireland

Northern Ireland

Bedroom and escape windows

Fire safety in new building work in Northern Ireland is covered by the Building Regulations (Northern Ireland) 2012 and Technical Booklet E. Where a room relies on a window for escape, nothing fitted over it should stop it being used. We only fit grilles over escape windows with a keyless internal release.

Listed buildings and conservation areas

Listed buildings in Northern Ireland need listed building consent for works affecting their character, with the council deciding and the Department for Communities' Historic Environment Division advising. Conservation areas bring extra scrutiny of external changes.

Window security grilles in Lisburn: questions

Can you survey in Lisburn and nearby towns?

Yes. Surveys in Lisburn, Belfast, Newtownabbey and elsewhere in County Antrim 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.

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.

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.
