Shop & commercial openings in Bath: how it works

Planning shop & commercial openings in Bath? Our team covers BA1 and BA2 and the streets around them. The wider Somerset area is covered as well. You get one written quote for the calculations, approvals, propping, steel and making good.

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

  • 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.
  • Joining two units can change the fire strategy. The wall between them may be a compartment wall, escape routes and travel distances alter, and the steel needs fire protection to the required period. The fire risk assessment should be updated to match the new layout.
  • Structural alterations to commercial premises need building regulations approval just as homes do, and in Scotland a building warrant before work starts. In England they usually go through a full plans application, because fire safety is assessed alongside the structure.
  • 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.
  • Commercial premises often have three-phase power, alarm and data cabling, gas supplies and drainage running through the walls being altered. These are mapped at the survey, and any work on gas pipes must by law be done by a Gas Safe registered engineer.

From survey to sign-off in Bath

  1. Survey in Bath

    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 Bath and North East Somerset Council, 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.

Approvals in Bath

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 Bath and North East Somerset Council 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.

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.

Shop & commercial openings in Bath: your questions

Do you cover Bath for shop & commercial openings?

Yes. We carry out shop & commercial openings in Bath and the BA1 and BA2 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

How much do shop & commercial openings cost in Bath?

As a guide, budget £5,150–£15,450 including VAT for shop or commercial structural opening in Bath, based on published UK cost guides adjusted for prices in the South West (+3%). 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.

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.

Can I knock two shops into one?

Usually, yes, with the right approvals. The dividing wall is replaced with steel designed by a structural engineer, building control approves the work and the fire strategy is updated for the combined unit. You also need landlord consent if you lease either unit, and party wall notices in England and Wales if the steel bears into a wall shared with another owner.

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.

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

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.
