Building rules in Derry/Londonderry
Building control in Derry/Londonderry is run by Derry City and Strabane District Council. Beams and new openings are controlled work under the Northern Ireland regulations, so we apply before anything is removed and the steel is inspected before it is covered.
The Party Wall etc. Act does not extend to Northern Ireland. Shared walls are dealt with under your title and the general law, so we recommend agreeing access and the work with your neighbour before it starts.
Steel beams in Derry/Londonderry: questions
Do you cover Derry/Londonderry for steel beam installation?
Yes. We carry out steel beam installation in Derry/Londonderry and the BT47 and BT48 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
Can you work on older or listed homes in Derry/Londonderry?
Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
Do I need a party wall agreement for steel beam installation in Derry/Londonderry?
There is no Party Wall Act in Northern Ireland. Your title deeds and the general law apply instead, so agree the work with your neighbour in writing before it starts.
Can I stay at home while the work is done in Derry/Londonderry?
Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.
Do you also work near Derry/Londonderry?
Yes. We also cover nearby towns including Strabane and Limavady.
