County Antrim centres on Belfast's red-brick terraces, Victorian city centre and commercial areas, with towns such as Lisburn, Ballymena and Larne.

  • Worn, stiff or seized locks
  • Lost or stolen keys
  • Bedroom grilles needing a keyless release
  • Sites wanting one key for every grille

Before the visit

Keyed alike

One key for all grilles is convenient for homes and small shops.

Like for like or upgrade

If the grille is sound, a better cylinder is a cheap upgrade.

Planning and safety 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.

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.

How it works

  1. Send a photo of the lock
  2. Choose like-for-like or upgrade
  3. Fitting and testing
  4. Keys and handover
