Key Accident Trends in the UK Construction Industry (2020/21)

Based on HSE (Health and Safety Executive) RIDDOR data for 2020/21, the UK construction sector saw 40 fatal injuries (rate 1.11 per 100k workers) — up from 1.08 in 2019/20.

Top 5 Fatal Accident Kinds

1. Falls from Height — 29% (11 deaths). Roofs, scaffolds, ladders, fragile surfaces.
2. Struck by Moving Vehicle — 18% (7 deaths). Site traffic: dumpers, excavators, telehandlers, delivery lorries.
3. Contact with Moving Machinery — 13% (5 deaths). Saws, drills, conveyors, mixers; inadequate guarding.
4. Falls Through Fragile Surfaces — 9% (4 deaths). Roof lights, asbestos cement, rotten boards.
5. Electrical Incidents — 8% (3 deaths). Overhead/underground cables, faulty equipment, wet conditions.

Key Trends

• Fatal count down long-term: 48 (2011/12) → 40 (2020/21) — but rate rising slightly (workforce shrinking).
• Construction = 80% of all industry fatalities (despite ~5% workforce).
• Small firms (<10 employees) = disproportionate fatalities — less formal safety management.
• Non-fatal injuries: ~61,000 (self-reported); leading causes: manual handling, slips/trips, falls <2m.
• Ill health > injury: ~78,000 workers with work-related illness (musculoskeletal, respiratory, stress).

Prevention Priorities (HSE)

• Work at height hierarchy (avoid → prevent → mitigate).
• Vehicle/pedestrian segregation (traffic management plans).
• Machinery guarding, maintenance, training.
• Fragile surface registers, safe access.
• Electrical: permits, testing, cable avoidance tools.
• Culture: leadership, worker engagement, competency (CSCS, CPCS).
