Fatal Injuries
Every death on a construction site is preventable. These statistics from the Health and Safety Executive paint a sobering picture of the current state of construction safety in the UK.
1. There were 45 fatal injuries to construction workers in Great Britain in 2024/25. Construction consistently accounts for the highest number of workplace fatalities of any industry in the UK. The 5-year average is 40 deaths per year.

2. Construction accounts for approximately 27% of all workplace fatal injuries, despite employing only 5% of the workforce. Workers in construction are disproportionately at risk compared to almost every other sector.
3. The fatal injury rate in construction is 1.72 per 100,000 workers. This is more than 4 times the all-industry average of 0.41 per 100,000. Agriculture (7.73) and waste management (3.96) are the only sectors with higher rates.

4. Self-employed workers account for 39% of construction fatalities despite being 38% of the workforce. Self-employed workers tend to work on smaller sites with less safety infrastructure, making them slightly more vulnerable.
5. Workers aged 60 and over have the highest fatal injury rate in construction. The rate for this age group is approximately 2.8 per 100,000, reflecting both physical vulnerability and the fact that older workers may be less likely to report near-misses.
6. Small sites (fewer than 15 workers) account for 57% of construction fatalities. Larger sites typically have dedicated safety managers, better systems, and more robust supervision. The risk concentrates on smaller projects. Read about how AI tools can help small construction companies close this gap.
Non-Fatal Injuries
7. There were approximately 54,000 non-fatal injuries in UK construction during 2024/25. This includes both RIDDOR-reportable injuries and those identified through the Labour Force Survey self-reporting.

8. Approximately 4,200 of these were classified as major or specified injuries. Major injuries include fractures (other than fingers/toes), amputations, crush injuries, and any injury requiring hospitalisation for more than 24 hours.
9. Construction workers lose an estimated 2.2 million working days per year due to workplace injury and ill health. This represents both the human cost of suffering and a massive economic productivity loss for the industry.
10. Slips, trips, and falls on the same level account for 28% of all non-fatal injuries. These are often dismissed as minor incidents, but they cause a significant number of fractures, sprains, and head injuries. Good housekeeping is one of the most effective prevention measures.
11. Being struck by a moving object causes 18% of non-fatal injuries. This includes being hit by falling materials, swinging loads, plant vehicles, and tools. Exclusion zones and proper lifting operations are critical controls.
12. Manual handling causes 16% of all reported non-fatal construction injuries. Lifting, carrying, and positioning heavy materials remains a primary source of musculoskeletal injuries, particularly to the back and shoulders. Our AI risk assessment guide covers automated identification of manual handling risks.
Common Causes of Fatal and Serious Injury
Understanding what kills and injures construction workers is essential for prevention. These figures reveal where the greatest risks lie.
13. Falls from height are the leading cause of death in construction, accounting for approximately 50% of all fatalities. This has been the case for decades and remains stubbornly high despite extensive regulation and awareness campaigns.

14. Being struck by a moving vehicle or object is the second leading cause, accounting for 18% of deaths. Excavators, dump trucks, and reversing vehicles are the most common types involved. Banksmen and vehicle separation are key controls.
15. Being trapped or crushed by a collapsing or overturning structure accounts for 12% of fatalities. Trench collapses, scaffold failures, and structural collapses during demolition are the primary incidents in this category.
16. Contact with electricity causes approximately 6% of construction deaths. Overhead power lines and underground cables are the most common sources. The "dial before you dig" principle prevents most contact incidents, but enforcement remains inconsistent.
17. Asbestos exposure causes approximately 5,000 deaths per year across all UK industries. Construction workers are disproportionately affected because asbestos is present in the majority of buildings constructed before 2000. It is the single largest cause of work-related death in the UK, though the deaths occur decades after exposure.

Working at Height
Working at height remains the single biggest killer in UK construction. These statistics explain why it demands such careful management. For compliance guidance, see our working at height regulations guide.
18. Falls from height killed approximately 22 construction workers in 2024/25. Falls from ladders, roofs, scaffolding, and through fragile surfaces are the most common fatal fall types.
19. Falls from ladders account for approximately 29% of all height-related fatalities. Ladders should only be used for low-risk, short-duration work, yet they remain one of the most commonly misused pieces of access equipment.
Source: HSE, Falls from height statistical summary
20. Falls through fragile surfaces (roofs, skylights, ceiling panels) cause approximately 15% of fatal falls. These are almost entirely preventable with proper surveys, barriers, and warning signage, yet they continue to occur year after year.
21. Scaffold-related incidents account for approximately 12% of height fatalities. Incomplete scaffolding, missing edge protection, and unauthorised modifications are the most common contributing factors.
22. The average height of a fatal fall in construction is just 3.2 metres. Most people assume fatal falls involve great heights, but a fall from a single-storey roof or the top of a stepladder can kill. This underscores why the 2-metre rule exists for mandatory edge protection.
23. 82% of working at height fatalities involved small contractors or sole traders. Larger contractors with dedicated safety teams and proper access equipment have significantly lower fall fatality rates.
Occupational Health and Illness
Injuries get the headlines, but occupational illness kills and disables far more construction workers over time.
24. An estimated 81,000 construction workers suffer from work-related ill health each year. This includes musculoskeletal disorders, respiratory disease, hearing loss, skin conditions, and mental health problems.
Source: HSE, Work-related ill health statistics
25. Musculoskeletal disorders affect an estimated 36,000 construction workers annually. Back pain, shoulder injuries, and knee problems are the most common, driven by manual handling, repetitive motions, and prolonged uncomfortable postures.
26. Occupational lung disease (including asbestosis, silicosis, and COPD) affects approximately 18,000 current and former construction workers. Dust exposure from cutting, grinding, and drilling operations is the primary cause for current workers.
27. Noise-induced hearing loss affects an estimated 12,000 construction workers. Construction is one of the noisiest work environments, with many tools and processes exceeding 85 dB. Once hearing is lost, it cannot be restored.
28. Hand-arm vibration syndrome (HAVS) affects approximately 8,500 construction workers. Extended use of vibrating tools (breakers, grinders, drills) causes nerve and blood vessel damage in the hands and arms. It is irreversible once established.
29. Construction workers are 3.7 times more likely to die by suicide than the national male average. Mental health in construction is a growing concern, with long hours, job insecurity, physical demands, and a culture that discourages seeking help all contributing factors.

30. Only 38% of construction firms provide mental health support or an Employee Assistance Programme. Despite growing awareness, most construction businesses, particularly SMEs, have no formal mental health provisions in place.

The Health and Safety Executive is the primary enforcer of construction safety law in the UK. These statistics show how actively they are pursuing non-compliance. For compliance checklists, see our CDM 2015 compliance checklist.
31. HSE conducted approximately 18,500 construction site inspections in 2024/25. This represents a 12% increase from 2023/24, reflecting a renewed focus on proactive enforcement following the post-pandemic increase in incidents.
Source: HSE Annual Report and Accounts
32. HSE issued 2,900 improvement notices to construction businesses in 2024/25. An improvement notice requires the duty holder to remedy a contravention within a specified time. Failure to comply is a criminal offence.
33. HSE issued 1,950 prohibition notices to construction businesses in 2024/25. A prohibition notice immediately stops a dangerous activity until the risk is remedied. These are used when there is a risk of serious personal injury.
34. Working at height violations are the most common reason for enforcement action, accounting for 32% of all notices. Followed by excavation safety (14%), structural stability (11%), and welfare provisions (9%).
35. The average fine for a health and safety conviction in construction is £115,000. Following the introduction of the Sentencing Guidelines in 2016, fines increased dramatically. Large organisations can face fines of £1 million or more for serious breaches.
Source: HSE prosecution outcomes data
36. HSE secured 142 convictions against construction companies and individuals in 2024/25. The conviction rate for prosecuted cases is approximately 94%, meaning that once HSE decides to prosecute, conviction is near-certain.
37. 14 construction company directors received custodial sentences in 2024/25. The courts are increasingly willing to imprison individuals who demonstrate gross negligence or deliberate disregard for safety.
CDM 2015 and Compliance
The Construction (Design and Management) Regulations 2015 are the primary regulatory framework for construction safety. Understanding compliance levels is essential. Our CDM compliance mistakes guide helps you avoid common pitfalls.
38. An estimated 62% of construction projects do not fully comply with CDM 2015 requirements. The most common deficiencies are inadequate pre-construction information, missing construction phase plans, and failure to appoint a principal designer on multi-contractor projects.
39. Only 44% of small construction firms (under 10 employees) have a formal health and safety policy. While firms with 5 or more employees are legally required to have a written policy, compliance among micro-firms is poor.
40. 73% of construction site managers say paperwork and documentation is their biggest challenge with safety compliance. The administrative burden of producing risk assessments, method statements, inspection records, and safety briefings is frequently cited as a barrier to better compliance. See how AI document generation can help.
The Cost of Poor Safety
41. Workplace injuries and ill health in UK construction cost an estimated £1.2 billion per year. This includes direct costs (medical treatment, compensation) and indirect costs (lost productivity, investigation time, replacement labour, project delays).
Source: HSE cost of workplace injury and ill health estimates
42. The average cost of a major injury to a construction employer is £38,000. This includes sick pay, investigation costs, temporary labour, equipment damage, and administrative time. It does not include potential fines or compensation claims.
43. Construction employers' liability insurance premiums have increased by an average of 24% since 2021. Rising claims costs, inflation, and an increase in the average claim value are driving premiums higher, particularly for firms with poor claims histories.
44. For every £1 spent on accident prevention, employers save an estimated £3-5 in avoided costs. The return on investment for safety spending is well-documented, yet many firms, particularly SMEs, still view safety as a cost rather than an investment. Read about how proper documentation protects your business.
What Is Working: Positive Trends
Despite the grim statistics, there has been real progress. These numbers show what works.
45. Fatal injuries in construction have fallen by 78% since 1981. When RIDDOR reporting began in 1981, there were approximately 166 deaths per year. The long-term trend is strongly positive, even if recent years have plateaued.
Source: HSE historical data
46. Sites using digital safety management tools report 31% fewer recordable injuries. Digital checklists, automated safety briefings, and electronic incident reporting improve consistency and accountability.
47. Companies with dedicated safety professionals have 52% fewer lost-time injuries. The evidence for investing in safety staffing is overwhelming, but many SMEs cannot afford full-time safety roles. AI tools are helping to bridge this gap.
48. Near-miss reporting reduces serious incident rates by 27% within the first year of implementation. Sites that actively encourage and track near-miss reports develop a stronger safety culture and identify hazards before they cause injury.
