Why Scaffold Inspections Should Be Mandatory: A Case Study
This case study supports our ongoing campaign for mandatory independent scaffold inspection — read the full campaign and our letters to Parliament, the HSE, and NASC here.
For months now, Statutory Scaffold Inspections Ltd has been campaigning for a change in the law: independent scaffold inspection should be a legal requirement, not an optional extra. We've written to our MP, to the Health and Safety Executive, and to the National Access and Scaffolding Confederation, setting out the case plainly. The core problem is simple. When a scaffolding contractor inspects its own scaffold, it is marking its own homework. There is no independent check, no second set of eyes, and no real accountability if standards slip.
Recently, we were given a stark illustration of exactly why this matters.
The Job
We were asked by a major UK banking group to inspect a scaffold connected to a subsidence claim. The scaffold in question had been in place for some time, and the client's records showed monthly charges consistent with regular inspections having taken place throughout. But when we carried out our independent assessment, the picture told a very different story. The scaffold was found to be in a dangerous condition — the kind of condition that should have been picked up, flagged, and corrected long before it reached this point. There was little to suggest that proper, competent inspections had been carried out at all, despite what was being charged for.
"Spirit level checking scaffold standard for plumb"
Checking standards for plumb using a spirit level, a basic check that should form part of every routine inspection.
Independent Scaffold Inspection: What We Found
Two defects in particular stood out as the kind of thing a proper, independent inspection is designed to catch.
"Scaffold base plate on concrete with a sole board that had completely Rotted away."
A standard was found bearing directly on the concrete footpath, the sole board beneath it had completely rotted away— offering none of the stable footing a loaded scaffold depends on.
"spanner sinking into rotten boards"
Elsewhere, a scaffold spanner was found sinking straight into rotten, decayed boards — boards that were carrying the weight of IBC water containers being used as kentledge to ballast the structure. Timber that had visibly failed was still being relied on to anchor significant ballast weight, and nobody had caught it.
Neither of these is a subtle defect. Both are the kind of thing a competent inspector checks for as a matter of routine — and both had apparently gone unnoticed for as long as this scaffold had been standing.
What the Client Told Us
After we completed the inspection, we asked the client — a Subsidence Indemnity Manager at a major UK banking group — whether he thought mandatory independent scaffold inspections would have made a difference in a case like this. His answer left no room for doubt:
"Yes, without doubt it would have made a difference on this occasion. Independent assessment must be better as you're not marking your own homework. As we can see with this job, inspections weren't even undertaken – even though the monthly amount would indicate that they were. The scaffold was in a dangerous condition and that would have been picked up much earlier and corrected or condemned."
This isn't a hypothetical concern raised by an inspection company with an obvious interest in the outcome. This is a senior figure at a major financial institution, dealing directly with the real-world consequences of a scaffold that was paid for, supposedly inspected, and left in a dangerous state.
Why This Keeps Happening
Cases like this aren't rare. Under the current system, the same contractor that erects a scaffold is often also responsible for inspecting it — and for invoicing the client for those inspections. There is no independent verification built into the process, and no consistent standard that guarantees the inspection actually happened, let alone happened properly. Voluntary good practice exists, but it isn't enforced, and as this case shows, it can quietly fail while a client continues to pay for a service they aren't receiving.
Other safety-critical industries have already solved this problem. Gas installations require Gas Safe registered inspection. Lifting equipment is governed by LOLER, with independent thorough examination built into the regulations. Electrical installations have long-established independent certification requirements. Scaffolding — used daily on construction sites and in situations like this one, adjacent to residential subsidence work — has no equivalent legal requirement for independent inspection.
What We're Asking For
We've written to the HSE requesting an amendment to Regulation 12 of the Work at Height Regulations 2005 (or updated ACOP guidance) to require that scaffold inspections be carried out by a competent person who is independent of the erecting contractor. We've raised the same issue with NASC and with our local MP, asking them to support the change and, where possible, raise it in Parliament.
Cases like this one are exactly why the change is needed. A dangerous scaffold — with a decaying base plate offering no proper footing, and rotten boards still carrying tonnes of water in kentledge — was charged for as if properly inspected, and only came to light because an independent assessor was brought in from outside. That shouldn't be the exception. It should be the standard.
Support the campaign
If you agree that scaffold inspection should be independent as standard, write to your MP and ask them to support amending the Work at Height Regulations 2005 to require it. You can also read our full campaign, including the letters we've sent to Parliament, the HSE, and NASC, here.
