Planning and safety in Northern Ireland
Grilles in rented homes
Private landlords in Northern Ireland have fitness and safety duties under the Private Tenancies (Northern Ireland) Order 2006, as amended by the Private Tenancies Act (Northern Ireland) 2022. Grilles over windows a tenant may need for escape should open from inside without a key.
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.

Grille lock replacement and upgrades in Carrickfergus: questions
Which areas near Carrickfergus do you cover?
We can arrange work in Carrickfergus and in nearby Holywood (6 miles), Newtownabbey (6 miles) and Bangor (7 miles). Dates depend on engineer availability.
Can a key-only grille be converted to quick release?
Often, yes, by fitting a lock with a keyless internal release. We check the grille first.

On a grille that is otherwise sound, a higher-security cylinder is an inexpensive way to raise resistance to lock attack.

Yes, on most makes, subject to compatible parts.
