Shop & commercial openings in St Helens: how it works
For homes in St Helens and the L35, WA9, WA10 and WA11 districts, we handle shop & commercial openings from survey to sign-off. We also work in nearby Liverpool, roughly 10.4 miles away. The beam is sized by a structural engineer and inspected before it is boxed in.
Commercial buildings often have a flat or offices above the shop, a heavy brick front and old steel or timber over the existing shopfront. Opening them up means supporting a lot of load at street level, usually with the public walking past, while keeping disruption to trading as low as possible.
Worth knowing before you start
- Commercial buildings built before 2000 should already have an asbestos register under the duty to manage. Before walls or ceilings are opened up, the register is checked and a refurbishment survey of the work area is arranged where it does not cover the job.
- A straightforward shopfront beam replacement can take a few days on site, while joining two units with several openings may run to a couple of weeks. The programme is agreed in writing before work starts so you can plan trading around it.
- The main cost factors are the span and load above, whether columns or a goalpost frame are needed, the temporary works at the street, out-of-hours working, lifting equipment, and the fire protection and finish the opening requires.
- Plenty of businesses keep trading while the work goes on. Dust screens, hoarding and phased working can keep part of the premises open, and the noisiest cutting can be programmed outside opening hours where the building and neighbours allow.
- Commercial openings tend to need longer, heavier steel than domestic work. Deliveries are planned around loading restrictions, and sections may be lifted with a small crane, telehandler or chain hoist, or spliced and bolted in place where the engineer allows.
Four stages, one team
Survey in St Helens
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 St Helens Council, 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.

Approvals in St Helens
Structural openings in English homes need building regulations approval before work starts. St Helens Council 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.
If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Questions about shop & commercial openings in St Helens
How much do shop & commercial openings cost in St Helens?
As a guide, budget £4,800–£14,400 including VAT for shop or commercial structural opening in St Helens, 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.
What happens at the survey visit in St Helens?
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.
Do I need my landlord's permission to put in a steel beam?
Almost certainly, if you lease the premises. Most commercial leases forbid structural alterations without the landlord's written consent, usually given as a licence for alterations. We can supply the engineer's calculations and drawings your landlord asks for, though the lease terms themselves are a matter for you and your solicitor.
How does fire safety change when two units are joined?
It can change significantly. The wall between the units may have been a compartment wall, escape routes and travel distances alter, and the new steel needs fire protection to the required period. Building control assesses this as part of the application, and the fire risk assessment for the premises should be updated for the new layout.
Do I need planning permission for a new shop front?
Often, yes. A new or altered shopfront usually changes how the building looks from the street, which can need planning permission, especially in a conservation area. Purely internal openings generally do not, but listed buildings need listed building consent for structural changes inside or out. It is worth checking with the local planning authority early.
