About our shop & commercial openings service in Croydon
If you live in Croydon, shop & commercial openings can usually be planned and priced after a single survey visit. The wider London area is covered as well. We cover CR0, CR2, CR7, CR9 and SE19, and we fix the price in writing once the layout and scope are agreed.
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
- 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.
- 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.
- 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.
- Many shopfronts sit under an old steel or timber beam hidden behind the fascia for decades. It may be corroded, undersized for what is above or bearing on decayed masonry, so it is opened up and checked before keeping it is even considered.
- 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.
Four stages, one team
Survey in Croydon
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 the local council's building control team, 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.

Building control and neighbours in Croydon
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.
Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Local questions answered
Can you work on older or listed homes in Croydon?
Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
Can I stay at home while the work is done in Croydon?
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 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 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.
Will I have to close my shop while the work is done?
Not always. Depending on the layout, the work area can be screened off with hoarding so part of the premises keeps trading, and the noisiest stages can be done out of hours. Some jobs, such as replacing the beam across the whole frontage, may need a short closure, which is planned well in advance.
How soon can shop & commercial openings start in Croydon?
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.
