30 Second Briefing
A construction worker suffered multiple fractures and a dislocated shoulder after a newly built wall collapsed and knocked him through an unprotected stairwell opening, causing a 2.5–3 metre fall onto a concrete floor at Ace Infra’s NW Auctions Milnthorpe site on 25 April 2024. HSE found no edge protection, incomplete boarding over the stair void, no warning signage, no task-specific instructions and no site supervisor present at the time. Ace Infra Ltd pleaded guilty to breaching Regulation 6(3) of the Work at Height Regulations 2005 and was fined £60,000 plus £4,799.44 costs and a £2,000 victim surcharge.
Technical Brief
- Failure mechanism combined a newly built wall collapse with an unprotected stair void, causing a lateral knock then vertical fall.
- HSE investigation focused on unaddressed fall risk at the stair opening and absence of preventative controls.
- Large stairwell opening had only partial temporary boarding; remaining gap was left without physical barriers.
- Worker was undertaking low-risk-perceived housekeeping (sweeping dust and debris) when exposed to the uncontrolled fall hazard.
- HSE cited Regulation 6(3) of the Work at Height Regulations 2005 regarding “suitable and sufficient measures” to prevent falls.
- HSE commentary stressed that any work at height, including around floor openings, requires formal planning and task-specific training.
Our Take
Among the 207 Safety/Failure-tagged pieces in our database, UK Health & Safety Executive (HSE) prosecutions like this Ace Infra Ltd case are a recurring subset, signalling that enforcement risk on smaller regional contractors in places such as Cumbria remains material rather than exceptional.
A 2.5–3 m fall leading to a month-long hospital stay is consistent with other serious fall-from-height incidents in our coverage, underlining that even ‘single-storey’ or mezzanine-level works on sites like NW Auctions Milnthorpe need full edge protection and temporary coverings treated with the same rigour as multi-storey builds.
For infrastructure operators using regional auction or logistics facilities similar to NW Auctions in Milnthorpe, this kind of HSE action tends to trigger tighter client pre-qualification on temporary works and floor opening controls, which can quickly become a competitive differentiator between contractors in the United Kingdom market.
