Planning shop & commercial openings in Tenby

We carry out shop & commercial openings in Tenby, covering the SA69 and SA70 postcode districts. The wider Pembrokeshire area is covered as well. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.

We carry out structural openings for small commercial premises across the UK, working to an engineer's design and handling building control. Work can be planned around opening hours, including out-of-hours shifts where the landlord and building allow, and coordinated with your shopfitter.

Things to plan for

  • Where there is a flat above the shop, its occupants need to know about the works and their safety has to be protected. Their access, fire escape route and the structure holding up their floor must all be maintained throughout the job.
  • 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.
  • 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.
  • 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.
  • 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.

Four stages, one team

  1. Survey in Tenby

    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 the application or notice to Pembrokeshire County Council under the Building Regulations as they apply in Wales, before work starts.

  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 Tenby

Welsh building regulations treat beams and new openings as controlled building work. We apply to Pembrokeshire County Council on your behalf before anything is removed, give the commencement notice the 2026 Welsh rules require, and the steel is checked before it is boxed in.

Where the steel bears into a wall shared with next door, notice must be served under the Party Wall etc. Act 1996. If your neighbour dissents, surveyors agree how the work is done before it starts.

Questions about shop & commercial openings in Tenby

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

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.

How much do shop & commercial openings cost in Tenby?

As a guide, budget £4,550–£13,650 including VAT for shop or commercial structural opening in Tenby, based on published UK cost guides adjusted for prices in Wales (-9%). 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 an asbestos survey before work on my shop?

Usually, if the building dates from before 2000. The duty holder for commercial premises should already have an asbestos register, and before walls, ceilings or the shopfront are opened up, a refurbishment survey of the work area is needed wherever that register does not cover it, so any asbestos is dealt with first.

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.

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 soon can shop & commercial openings start in Tenby?

Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
