Planning steel columns & posts in Crawley

Planning steel columns & posts in Crawley? Our team covers RH10 and RH11 and the streets around them. We also cover the surrounding towns and villages in West Sussex. You get one written quote for the calculations, approvals, propping, steel and making good.

We arrange the engineer's design, building control, the pad foundation, propping, supply and fixing of the column, and the boxing or finishing afterwards. You receive an itemised written quote, and the price is fixed in writing once the position, specification and scope are agreed.

Worth knowing before you start

  • Hollow sections, either square or circular, give a neat, slim profile and are common where a post stays on show. Universal columns have an H-shaped section and are often used where the post will be boxed in or built into a wall.
  • The base plate is welded to the foot of the column and fixed to the pad with holding-down bolts. A cap plate at the top bolts to the beam above, so the two act together and the beam cannot slide off its support.
  • Placing a post well can make an open-plan room work better. It can mark the edge of a kitchen island, frame a dining area or line up with a worktop end, so it reads as part of the design rather than an obstruction.
  • A post is needed when a beam has nothing adequate to bear on, or when a span is long enough that a central support gives a shallower, lighter beam. The engineer weighs up a column against a deeper beam for each layout.
  • Older properties sometimes have cast iron columns, timber posts or brick piers doing this job, especially in cellars and former shops. Their condition and capacity are often unknown, so the engineer assesses whether they can stay or need replacing with new steel.

How the job runs in Crawley

  1. Free visit

    A short visit to Crawley 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.

  4. Steel in, made good

    On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Approvals in Crawley

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.

Steel columns & posts in Crawley: your questions

How much do steel columns & posts cost in Crawley?

As a guide, budget £560–£1,680 per column including VAT for steel column or post in Crawley, based on published UK cost guides adjusted for prices in the South East (+12%). 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.

Do I need a party wall agreement for steel columns & posts in Crawley?

Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.

How long does it take to fit a steel post?

The column itself can often be fixed in a day, but the whole job usually spans a few working days. The floor is cut and the pad dug, building control inspects it, the concrete is poured and left to cure, and then the column goes in and is packed tight to the beam.

Do I need building control for a steel column?

Yes. A new structural column is building work under the building regulations in England and Wales, and needs a building warrant first in Scotland and a building control application in Northern Ireland. Inspectors normally check the foundation excavation and the fixed column before it is covered. We deal with the application, notices and inspection visits.

Can a steel column be left exposed?

Yes, many people leave a column on show, painted to suit the room. In homes exposed steel commonly needs fire protection, often intumescent paint applied to the specified thickness as part of a compatible paint system. Building control checks the protection meets what was specified. Boxing in with fire-rated plasterboard is the alternative where a hidden column is preferred.
