Does Public Liability Cover a Steel Fixer's Sign-Off on Structural Work?

A steel fixer’s physical work and a steel fixer’s certification are two different exposures. Only one of them is a public liability question. Placing and fabricating structural steel is physical work. Certifying that a connection meets requirements is a professional judgement. When that judgement turns out to be wrong, the claim looks nothing like a typical site incident.

Does public liability cover a steel fixer’s certification or sign-off?

No. Public liability responds to injury or property damage, not to a financial loss arising from advice or a professional opinion.¹ A steel fixer certifying a structural connection is doing something different to the physical work itself. It carries a separate exposure that generally needs professional indemnity alongside public liability, not public liability alone.

What actually happens when a sign-off comes back to the fabricator?

A steel fixer certifies a structural connection. It later fails inspection. The head contractor alleges the certification itself was negligent, not just that something went wrong on site. This sits outside public liability entirely. It’s a professional indemnity exposure, arising from the judgement behind the sign-off rather than the physical act of placing the steel.

This is worth taking seriously precisely because the physical work and the certification can look like one job from the outside, done by the same person, on the same day, as part of the same contract, while being two entirely separate things when a claim is actually assessed.

The financial impact reflects that split too. A public liability claim over a site incident is generally about the cost of the injury or damage itself. A negligent certification claim can carry a different kind of cost entirely: remediation of the structural element, engineering re-assessment of the whole connection or structure it sits within and delay costs while that work is redone. None of that flows from the physical placement of the steel. It flows from the sign-off being wrong.

Do all steel fixers need professional indemnity insurance?

Not necessarily. It comes down to what’s actually written into the contract and what the steel fixer is genuinely responsible for signing off on, not the job title on the invoice. This depends on whether the business only performs physical work to someone else’s specification or also certifies structural connections as part of the job. A steel fixer who purely executes work to a specification typically relies on public liability. A steel fixer who signs off on their own structural connections carries a separate professional indemnity exposure on top of it, whether or not the certification work is a large or small part of the overall job. This is worth reviewing even where certification only happens occasionally, since a single sign-off is enough to create the exposure regardless of how often it comes up.
