About our shop & commercial openings service in Preston

Need shop & commercial openings in Preston? The wider Lancashire area is covered as well. We survey the property, arrange the engineer's design, deal with local building control, fit the steel and make good, all under one quote for PR1, PR2 and PR5 addresses.

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.

Key points for your project

  • Most commercial leases prohibit structural alterations without the landlord's written consent, often given as a licence for alterations. Securing it before work starts avoids disputes later, and we supply the drawings and calculations the landlord or their surveyor asks to see.
  • 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.
  • 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.
  • 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.

Four stages, one team

  1. Look and measure

    We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.

  2. Design and price

    Calculations come back from the engineer and we confirm your fixed written price, line by line.

  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. Fit, inspect, finish

    The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Building rules for Preston

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.

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.

Local questions answered

What happens at the survey visit in Preston?

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.

How much do shop & commercial openings cost in Preston?

As a guide, budget £4,800–£14,400 including VAT for shop or commercial structural opening in Preston, 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 kind of steel is used for a wide shop front?

The engineer chooses the section to suit the span and load. Wide frontages often use universal beams, sometimes paired or plated, and a goalpost frame of two columns and a beam where the existing piers cannot take the load. The steel is then fire protected and finished behind the fascia or boxing.

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 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.
