A regional structural steelwork subcontractor based in South Wales, around 65 employees, turnover £14m. The business fabricates, supplies and erects structural steel for commercial buildings — distribution warehouses, light industrial units, mezzanine floors and the occasional mid-rise frame. The firm holds combined liability cover with a recognised construction-sector insurer, contract works cover on individual projects, and a separately placed legal expenses policy with HSE prosecution cover up to £500,000.
On a Tuesday morning in late November, an erector working on the second-floor steelwork of a four-storey office development near Cardiff fell approximately seven metres from a partially decked area. He sustained fatal injuries on impact. The deceased was a 34-year-old experienced erector with eleven years’ service, working as part of a four-person erection gang under the supervision of a charge-hand. The site was under principal contractor management by a national tier-one main contractor.
The Health and Safety Executive attended within four hours and immediately served a Prohibition Notice under section 22 of the Health and Safety at Work etc. Act 1974 stopping all steel erection work at height pending investigation. The site was secured. The HSE investigation extended over fifteen months and examined: the firm’s safe systems of work for steel erection, the documented risk assessment for the specific operation, the method statement for the floor decking sequence, the edge-protection provisions, the use of harnesses and lanyards, the supervision arrangements, the firm’s competence-assessment process for erectors, the principal contractor’s permit-to-work system, and the interface arrangements between trades on the floor in question.
Three specific findings emerged from the investigation. First, the method statement called for edge-protection to be installed progressively as decking advanced, but on the day of the accident the decking sequence had been altered to accommodate a delivery delay on the perimeter handrail components, and the erector had been working in an area where the planned edge-protection had not yet been installed. Second, the harness system in use was attached to a deck-mounted anchor but the lanyard length was longer than the fall-arrest distance, meaning the harness would not have arrested a fall to ground level from the working position. Third, the supervision arrangement on the day was such that the charge-hand was working on a separate floor and the erector was effectively unsupervised at the point of the accident.
The deceased’s family was supported through liaison and counsel. The firm’s managing director and operations director attended the funeral.
Three distinct workstreams emerged. The civil claim under the Fatal Accidents Act 1976 was intimated by claimant solicitors acting for the deceased’s widow and three young children, pleaded at approximately £1.4m on a dependency basis with Ogden multipliers applied. The HSE prosecution, initiated approximately fourteen months after the accident, charged the firm under sections 2(1) and 3(1) of the Health and Safety at Work etc. Act 1974 for failure to ensure the safety of an employee and failure to conduct undertakings without risk to others. A separate consideration of whether to charge the firm’s operations director personally under section 37 HSWA was undertaken; in this case the decision was not to pursue a personal charge, although that decision was finely balanced.
A coroner’s inquest under the Coroners and Justice Act 2009 was opened and adjourned pending the criminal proceedings.
The combined liability policy responded under the employers’ liability section on the civil claim. The EL section had a statutory minimum £5m limit but in practice was placed at £10m. The notification was made within forty-eight hours and the insurer instructed specialist construction sector defence solicitors. The civil claim settled at mediation eighteen months after the accident at £1.15m, after a process that drew heavily on the HSE investigation findings.
The legal expenses policy with HSE prosecution cover responded to the criminal defence. The £500,000 limit was tested — the matter went to a five-day trial in the Crown Court following a contested plea. The firm was convicted on both charges and fined £680,000 with prosecution costs of £124,000 awarded against it. The fine was calculated under the Sentencing Council’s Definitive Guideline for Health and Safety Offences by reference to the firm’s turnover (placing it in the “Medium” organisation category) and the seriousness of the breach (assessed as “harm category 1” given the fatality and “high culpability” given the systemic failings identified). The legal expenses cover responded to the £180,000 of defence costs incurred up to the £500,000 limit; the fine itself, as a criminal penalty, is not insurable under English law (consistent with the public-policy principle in Beresford v Royal Insurance Co and successor authorities).
The principal contractor’s own response added a layer. The tier-one main contractor served a contractual notice under the project’s framework agreement seeking indemnity from the subcontractor for any consequential losses arising from the site shutdown — programme delay, prelim costs and downstream client claims. The subcontractor’s combined liability cover, on the public liability side, engaged with this aspect after a careful argument about whether the principal contractor’s losses were “loss or damage” within the policy definition.
The total insured cost across the matter exceeded £1.9m before the uninsured criminal fine. The firm’s combined liability premium tripled at the following renewal and the legal expenses cover was rewritten with a £1m HSE prosecution limit. The firm engaged an external health and safety consultant to undertake a root-cause analysis and to assist in implementing changes to the firm’s method statement approval process, supervision arrangements and harness-system selection. The Construction Plant-hire Association and the British Constructional Steelwork Association both ran sector-wide alerts referencing similar incidents in 2026.
The deceased’s family received a long-term financial settlement and continues to be in occasional contact with the firm. The two foremen who had been on site that day both required substantial mental health support over the eighteen months following the accident; the firm’s combined liability extension for employee assistance funded the principal cost of that support.
Construction sector fatalities are tragic and not rare — the HSE’s most recent annual statistics record around forty fatal workplace injuries in construction each year, accounting for over a quarter of all UK workplace fatalities. First, the combined liability EL limit should not default to the £5m statutory minimum; £10m is increasingly the appropriate floor for steelwork, demolition and other high-severity-exposure trades. Second, HSE prosecution cover under a legal expenses policy is essential and the limit needs to reflect the realistic cost of a contested Crown Court trial — £500,000 is now arguably inadequate and £1m is increasingly market standard. Third, the Sentencing Guideline for health and safety offences calibrates fines by turnover and harm category; firms should understand which category they fall into and what fine range they would face on a worst-case finding. Fourth, the principal contractor’s framework agreement is increasingly the source of significant downstream commercial claims following a site shutdown; the public liability policy needs to be benchmarked against typical framework wording. Fifth, the method statement and risk assessment documentation is the single most important evidence in any prosecution defence — generic documents copied from project to project are increasingly indefensible.
We would have benchmarked the EL limit and the HSE prosecution cover limit at the previous renewal against current sentencing-guideline outcomes and would have specifically reviewed the combined liability policy’s response to principal-contractor framework indemnities. At notification, we would have coordinated the deployment of an independent health and safety expert to shadow the HSE investigation, and would have engaged specialist construction-sector criminal defence counsel at the earliest stage — the conversation with the HSE in the first three weeks materially affects the eventual charging decision. We would also have ensured the firm’s directors received separate legal advice on personal section 37 exposure distinct from the firm’s defence.
