Building control sign-off in Purley: how it works

Purley has a mix of housing, and building control sign-off needs a slightly different approach in each. We also cover the surrounding towns and villages in London. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.

Fitting a steel beam is controlled building work in every part of the UK, so the job is not finished when the plaster dries. Building control has to be told before work starts, inspect key stages such as the steel before it is covered, and confirm at the end that the work complies. That final confirmation is what solicitors and buyers ask to see.

Things to plan for

  • Building control charges are set by the body you use and are separate from the cost of the building work. They depend on the type and value of the work, and appear as their own line in our itemised quote.
  • 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.
  • You can use the local authority's building control service or a registered building control approver in England and Wales. Both inspect against the same regulations; the approver route works through an initial notice to the council and ends with a final certificate.
  • 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.
  • Other trades may need their own sign-off. Notifiable electrical work in England must meet Part P, signed off either by an electrician registered with a competent person scheme or through building control, and gas pipe work must by law be done by a Gas Safe registered engineer.

    A short visit to Purley to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building control

    We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.

Approvals in Purley

In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either the local council's building control team or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.

Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Building control sign-off in Purley: your questions

Can I stay at home while the work is done in Purley?

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.

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.

Do I need building control for a steel beam?

Yes. Fitting a steel beam is structural work covered by the building regulations in England, Wales, Scotland and Northern Ireland. Building control must be applied to or notified before work starts, it inspects the steel at key stages, and it issues or accepts a completion certificate when the work is finished. We arrange all of that.

What if my beam was fitted without building regulations approval?

In England and Wales you can apply to the local authority for regularisation, which is retrospective approval of unauthorised work. The inspector may ask for calculations and for parts of the work to be opened up so the steel and bearings can be seen. Any shortfalls must be put right before a regularisation certificate is issued.
