Skilled & Certified Scaffolders

Site staircases are the primary pedestrian route on any multi-storey commercial site, and the safest and most efficient way for trades to move between levels. Hundreds of people a day can use the stair on a busy main contractor site, which means it has to be robust, comfortable, and properly maintained. Ladder access is for emergency or fixed-point only on any serious commercial job. We install scaffold staircases across Milton Keynes and the surrounding counties — from single-flight entry stairs up to full-height stair towers running alongside tall scaffolds.

Our main system for commercial stair work is Layher StairCase — a prefabricated galvanised steel stair system that locks into standard Layher scaffold and installs at the same time as the main run. It's faster to erect than tube-and-fitting stairs, comfortable to use, and holds up to the traffic of a commercial construction site. For specialist applications we'll use alternative systems — plastic-treaded anti-slip stairs, wider double-flight towers, and mezzanine access stairs — and we'll spec the right option to the project.

What we handle:

  • Layher StairCase system as standard
  • Full-height stair towers integrated with main scaffold
  • Sure-grip treads and continuous handrails
  • Widths and landings matched to site flow
  • Emergency evacuation-rated designs
  • Roof-top and mezzanine internal access

When you need it

Typical scenarios where site staircases is the right call.

Main site access routes

Full-height stair towers serving as the primary pedestrian route from site compound to working levels on multi-storey construction sites.

Emergency evacuation routes

Secondary stair towers or internal emergency stairs sized to the project's emergency evacuation requirements under the construction phase plan.

Internal and mezzanine access

Internal scaffold stairs for industrial unit mezzanines, tank and plant room access, and temporary internal circulation during fit-out.

Why stairs matter more than they look

A scaffold stair is used by every trade on the site, every day, often many times a day. A bad stair slows down the whole job. Uncomfortable risers, inconsistent treads, missing landings on tall runs, or a stair that’s positioned far from the main work zones produces ongoing lost time across the whole trade mix. It’s one of those elements where small design choices compound across a long programme.

We install stairs with proper ergonomic consideration. Layher StairCase has consistent tread and rise throughout; landings every 2m of rise give resting points on tall runs; the stringers are sized to not flex under foot traffic; and the handrails are continuous without gaps at the landings. It’s better in daily use than tube-and-fitting alternatives, which is why we use it as our default for any commercial site stair.

Position drives productivity

The position of the main site stair is one of the most consequential logistics decisions on a multi-storey project — and one often delegated to the scaffolder by default. We’ll push back where the default position looks wrong. The stair should be close to the primary material delivery route, close to the main welfare and meeting points, and far enough from live work zones that stair traffic doesn’t interfere with work activity. We’ll advise at quote stage.

Stairs aren’t a material route

Worth repeating because it’s commonly blurred. Stairs carry people and small tools, not heavy materials. On any site with material flow above ground level, the stair package needs to sit alongside a hoist package — and where budget is tight the right call is almost always to spec the hoist properly and use the stair for personnel only.

If you’ve got an upcoming commercial site with stair requirements, get in touch and we’ll spec the stair package alongside the main scaffold.

Frequently Asked Questions

Are scaffold staircases DDA-compatible?
Fully DDA-compliant stairs aren't practical on a scaffold — the rise and going are outside Building Regulations for public use. But site staircases are designed to a comfortable and accessible spec for construction use, with consistent treads, continuous handrails both sides, and rest landings every 2m of vertical rise. Any true DDA access on site will usually be a passenger hoist, not a stair.
What's the stair width?
Standard Layher StairCase is 1m clear width, which accommodates one-way traffic comfortably and two-way traffic where pedestrian volumes are low. For busy main-contractor sites with two-way traffic or for emergency evacuation stairs we'll install double-width stairs, either two parallel stairs or a wider tower system.
How does it integrate with the scaffold?
Layher StairCase locks into the main Layher scaffold using the standard node connections. It's erected at the same time as the main scaffold, stripping and altering on the same cycle. For tube-and-fitting scaffolds we can integrate scaffold stairs using matching couplers, though the install is slower.
Can you provide emergency evacuation stairs?
Yes. Evacuation stairs are sized to the CDM Principal Contractor's emergency evacuation plan — typically wider than a normal site stair, with outward-opening doors at each level, and positioned to give an unobstructed route from any occupied working position. We'll work to the main contractor's fire strategy on any large job.
Can the stair be used as a public access route?
On most commercial sites, the scaffold stair is for site personnel only. For any scaffold with genuine public-facing access — for example a shop that stays open during façade work — we'd usually recommend a Public Access Scaffold design rather than a standard site stair. Get in touch at quote stage and we'll spec accordingly.
What's the load rating?
Layher StairCase is rated for typical construction pedestrian loading with capacity for small hand-tools and light materials. It is not a materials access route — heavy materials go on the hoist, not up the stair. We'll mark the stair loading on the scaffold drawings at handover.
