Scaffold types
Access Scaffolds
An access scaffold does exactly what its name says: it gets people, tools and materials safely to the part of a building they need to work on. It’s the general-purpose workhorse of the trade – and the type most scaffolding contracts, and most scaffolding insurance policies, are written around.
What counts as an access scaffold?
Access scaffolding covers the familiar boarded platforms erected against a building face for maintenance, repair, painting, pointing and construction work. The two traditional forms are the independent tied scaffold, with its double row of standards, and the putlog scaffold, which borrows support from the wall it serves. Both exist for the same purpose: a stable working platform, at the right height, with safe access to it.
The platform is the point
Everything about an access scaffold is judged by the platform it provides. Boards must be fully decked with no gaps, closely supported by transoms, and protected at the edges by double guardrails and toe boards wherever a person could fall 2 metres or more. Ladder access should be built in from the start, not improvised at the end – a surprising number of scaffold incidents happen getting on and off the structure rather than working from it.
Platform width matters too. A scaffold sized for an inspection walkway won’t do for bricklaying, where materials are stacked and loads concentrate. Agreeing the platform’s duty – inspection, general purpose, or heavy duty – before erection is one of those five-minute conversations that prevents both accidents and disputes.
Inspection and alteration
Like every working scaffold, an access scaffold needs inspecting after erection, then at intervals of no more than seven days, and again after any alteration or bad weather. Only a competent person should adapt the structure – removing a tie or a brace to squeeze materials through has been the first chapter of many collapse reports.
How an access scaffold goes up
A typical erection sequence starts at the ground: sole boards and base plates set out on firm, level bearing, then the first lift of standards and ledgers squared and levelled before anything climbs higher. Transoms follow to carry the boards, ledger bracing stiffens the frame, and ties into the building go in as the lifts rise – not as an afterthought once the scaffold is topped out. Guardrails, toe boards and ladder access complete each working lift before it’s handed over.
The sequence matters because a scaffold is at its most vulnerable mid-erection. That’s why the law restricts erection, alteration and dismantling to competent people – on most commercial sites, that means operatives holding a CISRS card, the industry scheme described in our scaffolding regulations guide. On handover, a scaffold tag or handover certificate records what the structure is designed to carry and who checked it.
Common defects to catch at inspection
The statutory inspection regime – after erection, every seven days, and after alteration or bad weather – exists because access scaffolds degrade in predictable ways. The defects that come up again and again: missing or displaced boards leaving traps and gaps; guardrails removed to land materials and never refitted; ties taken out by following trades; base plates undermined by excavation or washed-out ground; and incompatible or damaged couplers doing load-bearing work they were never rated for. Our scaffolding safety guide covers the inspection regime in more detail, and the right scaffolding tools – tethered, maintained and correct for the job – prevent half of these defects arising in the first place.
The insurance angle
Because access scaffolds stand where the public passes – pavements, entrances, shopfronts – they carry the classic public liability exposures: falling objects, protruding tubes at head height, and unauthorised access out of hours. Fans, brick guards, tube end caps, lighting and alarms all reduce the risk, and all strengthen your position if a claim ever lands. If the scaffold obstructs a footway it also needs displaying the right scaffolding signs – hazard warnings for the structure and advisory notices for anyone passing through.
Access scaffold FAQs
How often must an access scaffold be inspected?
After it’s first erected, then at intervals of no more than seven days for as long as it stands, and additionally after any alteration or event likely to have affected it – high winds being the classic example. Inspections must be done by a competent person and the results recorded.
Do I need a licence for an access scaffold?
Only if it stands on or over the public highway, including the pavement – in which case the contractor obtains a licence from the local authority, and the property owner should check it exists and stays valid. Scaffolds entirely on private land don’t need one. The detail is in our regulations guide.
What’s the difference between an access scaffold and a working platform?
The working platform is the boarded deck you stand on; the access scaffold is the whole structure that supports it and gets you to it. In practice the terms travel together – a scaffold is only as good as the platform it provides.
Who is responsible if a member of the public is injured by an access scaffold?
It depends on the cause – erection defects point at the scaffolding contractor, site management failures at the principal contractor or client. What’s certain is that everyone involved will need their public liability insurance, which is why appropriate cover is effectively a condition of every scaffolding contract.
Cover for every platform you put up
Access scaffolding is where most liability claims start – make sure your policy is built for it.
