Is this RIDDOR-reportable?
The UK Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 — known universally as RIDDOR — split into four reportable categories: Reg 4 fatalities, Reg 5 specified injuries (amputation, hospitalisation greater than 24 hours, loss of consciousness, and a longer list of serious injuries), Reg 6 over-seven-day incapacitation (strict more-than-seven), and Reg 8 occupational diseases (Schedule 1 listed conditions). RIDDOR is severity-gated — the UK accident book (BI 510) records the broader case set; RIDDOR reporting is reserved for the serious end.
Why this matters
RIDDOR is severity-gated. The bar is higher than OSHA + the threshold is days, not visits.
A US-trained EHS manager arriving at a UK site brings the OSHA 1904.7 cascade: "Did the worker need medical treatment beyond first aid?" Under UK law, that question doesn't matter for RIDDOR — only for the BI 510 accident book + SSP (Statutory Sick Pay) administration. RIDDOR's Reg 6 incapacitation trigger fires at more than seven consecutive days excluding the day of the accident, not at one. A trip-and-fall that needs a few stitches and a day's rest isn't RIDDOR-reportable; it goes in the accident book.
The specified-injuries list (Reg 5) is the big-ticket category: amputation, scalping, loss of vision, crush injuries, serious burns, scalping (yes, listed), unconsciousness from head injury or asphyxia, anything requiring hospitalisation greater than 24 hours, and a longer list at HSE.gov.uk. SE's universal model maps the most common cases — amputation/eye-loss + hospitalisation > 24h + loss-of-consciousness — directly; the finer per-injury types are a polish slot when first UK customer data surfaces a gap.
Reg 8 occupational diseases cover Schedule 1 listed conditions — occupational dermatitis, occupational asthma, hand-arm vibration syndrome, occupational deafness, occupational cancer caused by listed agents, biological diseases from work exposure. Distinct register from the acute-injury cases.
The cascade
How RIDDOR Regs 4 / 5 / 6 / 8 actually decide.
-
Work-related?
If no, no RIDDOR. If unsure, hold the determination until the investigation closes.
-
Reg 4 — fatality?
Work-related death of any person (employee, contractor, member of the public). Immediate notification to HSE — fastest reporting route is online or the HSE Incident Contact Centre. F2508 follows within 10 days.
-
Reg 5 — specified injury?
Amputation, permanent vision loss, hospitalisation greater than 24 hours, loss of consciousness from head injury or asphyxia, scalping, crush injuries, serious burns (more on the HSE site). Each triggers a F2508 within 10 days.
-
Reg 6 — over-seven-day incapacitation?
Worker incapacitated more than seven consecutive days — strict greater-than. Day of the accident itself doesn't count. F2508 within 15 days.
-
Reg 8 — occupational disease?
Schedule 1 listed disease diagnosed by a doctor. F2508A within 15 days.
-
Otherwise: not RIDDOR-reportable.
The case still belongs in the BI 510 accident book + SSP administration. RIDDOR is severity-gated; minor injuries don't reach the HSE.
Common gotchas
The RIDDOR rules that bite people.
- "Day of accident" doesn't count toward the seven days. Injury Monday, return-to-work Wednesday-next-week (so Tue-Mon = 7 days off) is exactly seven — strict greater-than means NOT Reg 6. Return on Tuesday-next-week = 8 days = Reg 6.
- Reg 5 is broader than the common cases. SE's universal model surfaces amputation + hospitalisation > 24h + loss-of-consciousness; the full RIDDOR list also covers scalping (any size), serious burns (full thickness ≥10% of body OR critical area), reduced vision, crush injury to head/torso, internal organ damage from chemical exposure, and others. When in doubt, F2508.
- "Hospitalisation" means admitted-as-an-inpatient. A visit to A&E followed by discharge same-day is NOT Reg 5 hospitalisation. Overnight admission for observation IS.
- Reg 8 requires a doctor's diagnosis. Self-reported "I think I have occupational asthma" doesn't trigger Reg 8. The diagnosis is the trigger; the case isn't RIDDOR-reportable until a GP / occupational health doctor / consultant writes it down.
- F2508 vs F2508A. Injuries are F2508 (10-day filing window for fatalities + specified injuries; 15 days for over-7-day). Diseases are F2508A (15 days). Get the form right.
Walk your case through the cascade.
The interactive walkthrough asks four questions — work-relatedness, outcomes, days off when applicable, and whether the case is an injury or a Schedule 1 occupational disease — and produces the verdict with regulation citations + the filing form (F2508 or F2508A) and timeframe.
SE walks the same RIDDOR cascade for every customer incident at a UK establishment — with the F2508 / F2508A renderer wired in + a single-national-HSE filing posture (no regional sub-routing, unlike the US OSHA state plans or NL postcode-prefix districts). See SE's multi-jurisdiction depth →
