About our temporary works & propping service in Pimlico

For homes in Pimlico and the SW1, W1 and WC2 districts, we handle temporary works & propping from survey to sign-off. We also cover the surrounding towns and villages in London. The beam is sized by a structural engineer and inspected before it is boxed in.

The moment a load-bearing wall is cut, whatever it was holding needs another route to the ground. Temporary works provide that route. Done well, nothing above moves, ceilings stay intact and the floor below is not overloaded. Done badly, it is where structural work goes wrong.

Things to plan for

  • Props and needles cannot go where pipes, cables or flues run. Their positions are checked against services before any holes are cut, and anything in the way is isolated or rerouted first by the appropriate trade.
  • Propping normally goes in on the first morning and stays until the beam is carrying. For a typical opening that is a few days, and longer where padstone mortar needs time to cure before the load is transferred onto it.
  • When an external wall is propped, the opening is sheeted against rain and the house is kept secure overnight. Where props stand outside, ground conditions, drains and access paths are taken into account before they are set up.
  • In the UK, temporary works are generally managed following BS 5975, the code of practice for temporary works procedures. On bigger jobs that means a named coordinator, a written design and checks before props are loaded or taken out.
  • Typical mistakes include props standing on unsupported floorboards, missing spreaders so one joist takes all the load, and props wound up too hard so the ceiling lifts and cracks. Careful setting out and gradual tightening avoid all three.

How the job runs in Pimlico

  1. Survey in Pimlico

    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

    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.

  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.

Building control and neighbours in Pimlico

For Pimlico, building control is provided by the local council's building control team, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.

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.

Temporary works & propping in Pimlico: your questions

Can you work on older or listed homes in Pimlico?

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.

How much do temporary works & propping cost in Pimlico?

As a guide, budget £190–£640 including VAT for temporary works and propping in Pimlico, based on published UK cost guides adjusted for London prices (+28%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.

Does temporary propping need building control approval?

Not on its own, but the structural work it supports usually does. Removing a load-bearing wall or inserting a beam needs building regulations approval in England, Wales and Northern Ireland, and a building warrant in Scotland. The propping arrangement normally forms part of the engineer's calculations sent with that application.

Can I hire props and support a wall myself?

Props can be hired, but propping a structure is skilled work with serious consequences if it goes wrong. The arrangement should come from an engineer's design, and the loads, floor strength and sequence all need checking. Structural propping should be left to a competent team working to that design.

How long do props have to stay in after a beam is fitted?

Until the permanent steel is packed tight and able to carry the load. That includes time for the padstone and packing mortar to gain enough strength, which depends on the mix and the weather. On a typical opening, props are in for a few days before being released gradually.
