Things to decide before you order
Inside or outside
Inside fixing keeps the grille away from weather and tampering. Outside fixing suits windows with no internal access or depth.
Appearance
On front elevations or period buildings a decorative or slimmer bar pattern may sit better than a plain grid.
Rules that apply in 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.

Fixed window grilles and bars in County Londonderry: questions
Which towns in County Londonderry do you cover?
We can arrange work anywhere in County Londonderry, including Coleraine, Derry, Limavady and Magherafelt.
Can fixed bars go on a bedroom window?
Generally no. Bedroom and upstairs habitable room windows often need to work as escape windows, so they should have an openable grille with a keyless internal release.
Will fixed bars rust?
Galvanised and powder-coated steel is designed for years of outdoor use. Chips in the coating should be touched up to keep the protection intact.
Do fixed grilles need planning permission?
Internal fixed grilles usually do not. External grilles on front elevations, listed buildings or in conservation areas may need consent, so we check before ordering.
