Planning shop & commercial openings in Sevenoaks

Our shop & commercial openings service in Sevenoaks covers everything from the first visit to the completion paperwork. We also work in nearby Maidstone, roughly 14.2 miles away. Postcode districts we cover here include TN13 and TN14.

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

  • Purely internal works may not need planning permission, but a new or altered shopfront changes the look of the building and may need it, particularly in a conservation area. Listed commercial buildings also need listed building consent for structural changes.
  • 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.
  • 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.
  • 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.
  • 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.

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 Sevenoaks

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.

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 Sevenoaks

How much do shop & commercial openings cost in Sevenoaks?

As a guide, budget £5,600–£16,800 including VAT for shop or commercial structural opening in Sevenoaks, based on published UK cost guides adjusted for prices in the South East (+12%). 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 you also work near Sevenoaks?

Yes. We also cover nearby towns including Tonbridge, Swanley, Tunbridge Wells and Caterham.

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 commercial steel beam work be done outside opening hours?

In many cases, yes. Noisy cutting and the main structural stages can be programmed for evenings, early mornings or weekends where the landlord, the building and neighbouring occupiers allow. Out-of-hours working is priced as a separate line on the itemised quote, so you can weigh it against closing for part of the job.

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 a party wall agreement for shop & commercial openings in Sevenoaks?

Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.
