Planning building control sign-off in Belfast

We carry out building control sign-off throughout Belfast, for homeowners, landlords and builders who need the structural part done properly. We can survey in places such as Castlereagh and the villages around them. You get an itemised written quote that shows the calculations, approvals, steel, labour and finishing as separate lines.

Key points for your project

  • Most work that removes, alters or adds to the structure of a building is controlled under the building regulations. That includes taking out load-bearing walls, inserting beams or columns, and forming or widening openings in external walls, whether in a house, flat or shop.
  • Keep the completion certificate with the engineer's calculations and drawings. Lost certificates can usually be traced through the building control body that issued them, but having your own copy saves time when you remortgage or sell.
  • Flats and commercial premises bring extra considerations. Leaseholders usually need the freeholder's consent as well as building control approval, and in shops or mixed-use buildings the inspector may look closely at fire separation and escape routes affected by the work.
  • The most important visit is usually the one before the steel is covered. If a beam is boxed in before the inspector has seen it, the boxing may have to be opened up again, which adds cost and delay.
  • Conveyancing solicitors routinely ask for completion certificates for structural alterations. Missing sign-off can delay a sale or prompt the buyer to ask for retrospective approval or a lower price, so it pays to close the paperwork while the work is fresh.

From survey to sign-off in Belfast

  1. Survey in Belfast

    We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.

  2. Engineer's design

    A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.

  3. Building control

    A full plans application or building notice goes to Belfast City Council under the Building Regulations (Northern Ireland) 2012 before work begins.

  4. Install and sign-off

    Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Approvals in Belfast

Removing a load-bearing wall in Northern Ireland needs building control approval from the council. Belfast City Council covers Belfast. The engineer's calculations support the application, and a completion certificate is issued after the final inspection.

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.

Local questions answered

What happens at the survey visit in Belfast?

We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.

When does building control inspect a steel beam?

Inspectors usually want to see the steel in position, sitting on its padstones or columns and packed tight, before it is boxed in or plastered. They may also check foundation excavations for columns and come back for a final inspection. We book each visit so the work does not get covered up too early.

Are building control fees included in the quote?

Yes. Our itemised written quote lists the building control charge separately, so you can see it apart from the building work. The charge itself is set by the building control body rather than by us, and depends on the type and scale of the work and the route chosen.
