Steel goalpost frames in Lancashire: how it works
A steel goalpost frame is a beam supported on two steel columns, bolted together into one rigid unit shaped like a goalpost. It is used where the masonry either side of an opening cannot take the beam's load, or where a wide opening leaves little wall to bear on. The columns stand on base plates fixed to concrete pad foundations sized by the engineer.
Homes across Lancashire range from Victorian terraces to post-war semis and newer estates, and steel goalpost frames look different in each. That includes Preston, Leyland and Skelmersdale, plus smaller towns and villages nearby. We plan the steel, the temporary support and the approvals around the building, then fix the price in writing once the scope is agreed.
What to expect
- Digging the column pads means breaking through the floor, which is noisier and messier than fitting a beam alone. Floor coverings near the column positions need lifting, and the spoil from the excavations is bagged and removed from site.
- While the old wall or piers come out, the floor, walls and roof above are held on props and needles. These stay in until the frame is fully bolted, levelled and packed, so the structure is never left without support.
- A goalpost frame is structural work, so building regulations approval is needed in England and Wales, a building warrant before work in Scotland, and a building control application in Northern Ireland. The inspector typically wants to see the pad excavations as well as the finished steel.
- Price depends on the opening width, the loads the beam carries, the number of bolted connections, the depth of the pads and how easily the steel can be carried in. Any redesign after the ground is opened is priced before it goes ahead.
- Columns are commonly universal columns or square hollow sections, welded to steel base plates at the foot and cap plates at the head. Holding-down bolts fix the base plates to the pad, and grout fills the gap beneath once the frame is level.
What happens, step by step
Survey in Lancashire
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.
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.
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.
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.
What do steel goalpost frames cost in Lancashire?
As a guide, budget £1,900–£5,750 including VAT for steel goalpost frame in Lancashire, based on published UK cost guides adjusted for prices in the North West (-4%).
| Job | Typical guide range | What it usually covers |
|---|---|---|
| Steel goalpost frame | £1,900–£5,750 | Two posts and a beam bolted as a frame, pad foundations, base plates and fitting |
| Opening into a rear extension | £2,400–£6,700 | Original rear wall removed with a beam or goalpost, approvals and propping, coordinated with the extension build |
| RSJ supply and fit (single beam) | £770–£2,400 per beam | Beam supplied, delivered, lifted and packed on padstones, with propping (calculations and approval priced separately) |
| Structural calculations for a beam | £240–£720 | Site measure or photos, beam and padstone design and calculations for building control |
Figures include our approximate regional adjustment for prices in the North West (-4%) and are rounded. How these figures are worked out.
Approvals in Lancashire
Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.
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.
Local questions answered
How much do steel goalpost frames cost in Lancashire?
As a guide, budget £1,900–£5,750 including VAT for steel goalpost frame in Lancashire, based on published UK cost guides adjusted for prices in the North West (-4%). 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.
Can I stay at home while the work is done in Lancashire?
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.
Can a goalpost column go next to my neighbour's wall?
It can, but in England and Wales it may bring in the Party Wall etc. Act 1996. Digging a pad near a neighbour's building to below the level of its foundations, or fixing into a shared wall, can be notifiable. We arrange notices through a party wall surveyor where needed. There is no equivalent Act in Scotland or Northern Ireland.
When do you need a goalpost instead of a steel beam?
You need a goalpost when the walls at either end of the opening cannot safely carry the beam. That happens when piers are too narrow, the masonry is weak or cracked, the opening runs almost wall to wall, or the footings below are unsuitable. The structural engineer makes the call after looking at the loads and the bearings available.
Do I need building regulations approval for a goalpost frame?
Yes. Installing a goalpost frame is structural building work. In England it needs building regulations approval through a full plans application or building notice, in Wales an application under the Welsh regulations, in Scotland a building warrant must be granted first, and in Northern Ireland the council's building control is applied to before work begins. We arrange the application and inspections.
What is the difference between a goalpost and a portal frame?
A domestic goalpost is a simple version of a portal frame. Both use columns and a beam joined together, but a full portal frame has rigid joints designed to resist sideways loads on its own, as used in steel-framed industrial buildings. In a house, the engineer decides how rigid the goalpost joints need to be for that opening.
