Last updated: 17 October 2026
Accident book requirements UK employers must follow stem from the Social Security (Claims and Payments) Regulations 1979, which oblige any employer with 10 or more employees to keep an accident book and retain entries for at least three years from the incident date, Express Solicitors (2026) confirms.
Key Takeaways
- Employers with 10 or more staff must legally keep an accident book under the Social Security (Claims and Payments) Regulations 1979, retaining records for at least three years, per Express Solicitors (2026).
- An estimated 680,000 UK workers suffered a non-fatal workplace injury in 2024/25, up from 613,000 the year before, according to Safesmart / HSE Annual Statistics (2025).
- 59,219 employee injuries were reported under RIDDOR in 2024/25, the second-lowest figure on record, per Safesmart / HSE Annual Statistics (2025).
- The accident book is not the same as a RIDDOR report — every reportable injury goes in the accident book, but most accident book entries never meet the RIDDOR threshold.
- Over-seven-day injuries must reach the HSE within 15 days, while fatalities and specified injuries must be reported without delay and within 10 days, per HASpod (2026).
Is it a legal requirement for UK employers to keep an accident book?
Yes — an accident book is a statutory record of workplace injuries and incidents that certain UK employers must maintain by law. Employers with 10 or more employees fall under this duty via the Social Security (Claims and Payments) Regulations 1979, and must keep entries for a minimum of three years from the date of the incident, according to Express Solicitors (2026).
Smaller employers below that threshold aren't caught by the specific 1979 duty, but most keep one anyway. The Health and Safety at Work etc. Act 1974 places a general duty on all employers to manage risks to employee health and safety, and a documented accident record is the practical way to demonstrate that. Security and facilities firms with lone workers on remote sites — car parks, plant rooms, construction hoardings — are especially exposed if there's no record to point to after an incident.
For operators managing multiple sites, this is where paper falls down fastest: a book left in a cabin on one site is no use when the incident happens three miles away on another.
Which law or regulation covers accident book requirements in the UK?
Three overlapping legal frameworks govern accident book requirements UK-wide, and confusing them is the most common compliance mistake. The Social Security (Claims and Payments) Regulations 1979 create the duty to keep the book itself for employers with 10-plus staff. The Health and Safety at Work etc. Act 1974 sets the broader duty of care that the accident book helps evidence. The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 — RIDDOR, enforced by the Health and Safety Executive (HSE) — sits alongside, requiring certain serious incidents to be formally reported to the regulator, not just logged internally.
The HSE publishes an official accident book product known as BI 510, sold through HSE Books. It's designed to satisfy both the 1979 Regulations and UK GDPR data protection requirements, using a tear-out page format so each entry stays confidential to the individual involved rather than sitting visible to the next person who opens the book.
Who is responsible for maintaining the accident book in a workplace?
The employer holds ultimate legal responsibility for maintaining the accident book, though day-to-day upkeep is usually delegated to a named individual such as a health and safety officer, site supervisor or duty manager. That person logs entries, checks completeness, and ensures the book (or its digital equivalent) is accessible to whoever is on shift when an incident occurs.
In multi-site security and facilities operations, this delegation model breaks down fast. If each site manager keeps their own paper book, head office has no visibility until someone physically drives out to collect it — often weeks after the fact. Pulse Operations applies the principle on a Priority First site in West London covering 152 checkpoints across retail, residential and plant areas, where the same logic that applies to patrol verification applies to incident recording: proof needs to be captured at the point of occurrence, not reconstructed afterwards. Pulse Operations's incidents and occurrence book module logs entries the moment they happen, timestamped and attributed to the officer on duty, so a control room manager sees a new incident the same shift it's raised rather than finding out at month-end.
What types of incidents must be recorded in the accident book?
The accident book must record any injury, however minor, that happens to an employee in the course of their work. This includes cuts, slips, minor burns, manual handling strains, and near-miss incidents that could have caused harm even if nobody was hurt. Employers should also log incidents involving visitors, contractors or members of the public on their premises, since these may carry liability implications even though the Social Security Regulations were originally framed around employees.
The most common causes of workplace injury nationally are worth knowing when training staff on what to log. HSE data for 2024/25 shows slips, trips or falls on the same level account for 30% of RIDDOR-reported non-fatal injuries, handling, lifting or carrying for 17%, being struck by a moving object for 10%, acts of violence for 10%, and falls from height for 8%.
For security officers, acts of violence and lone-working incidents deserve particular attention — a doorman assaulted on a Friday night shift, or a mobile patrol officer confronted at a keyholding call-out, both belong in the record even if no formal RIDDOR report follows.
What specific information needs to be recorded for each accident entry?
An accident book entry is a structured record capturing who was involved, what happened, when, where, and what the consequences were. A complete entry should include: the injured person's full name and job title, the date, time and precise location of the incident, a factual description of what occurred, details of any injury sustained, first aid or medical treatment given, and the name of the person completing the record.
Under UK GDPR — the retained EU General Data Protection Regulation, enforced by the Information Commissioner's Office (ICO) — accident entries count as personal data, and where they touch on health information, as special category data requiring extra care. This is precisely why HSE's BI 510 book uses individually removable, confidential pages: nobody flicking through the book can read another employee's medical details.
| Field | Why it matters |
|---|---|
| Full name, job title | Identifies the injured party for follow-up and RIDDOR assessment |
| Date, time, exact location | Establishes sequence of events and site liability |
| Description of incident | Factual account, not opinion or blame |
| Nature of injury | Supports medical follow-up and severity grading |
| Treatment given | Evidence of first aid response and its adequacy |
| Witness details (if any) | Corroborates the account for insurance or investigation |
| Recorder's name and date | Establishes accountability for the entry itself |
How does the accident book relate to RIDDOR reporting requirements?
The accident book and RIDDOR reporting are two distinct but connected duties, and every employer needs to understand where one ends and the other begins. The accident book captures every workplace injury, however minor. RIDDOR reporting only applies to a narrower set of serious incidents — deaths, specified injuries, incidents causing more than seven days' incapacitation, certain occupational diseases, and dangerous occurrences — that must be reported directly to the HSE.
Timing matters here and it's strict. Fatalities and specified injuries must be reported without delay and within 10 days, while over-seven-day injuries must reach the HSE within 15 days of the accident, according to HASpod (2026). Missing that window is itself a compliance failure independent of the original incident.
Nationally, 59,219 employee injuries were reported under RIDDOR in 2024/25 — the second-lowest figure on record — against an estimated 680,000 total non-fatal workplace injuries, per Safesmart / HSE Annual Statistics (2025). That gap illustrates the point precisely: the vast majority of accident book entries never become RIDDOR reports, but every RIDDOR report should be traceable back to an accident book entry. There were also 124 worker fatalities in 2024/25, 14 fewer than the previous year and below the five-year average of 133, per HSE (2025), and the RIDDOR-reported non-fatal injury rate stood at 209 per 100,000 employees, continuing a downward trend, according to HSE (2025).
How long must an employer keep completed accident book records?
Employers must retain accident book records for a minimum of three years from the date of the incident, under the Social Security (Claims and Payments) Regulations 1979, per Express Solicitors (2026). This minimum exists because personal injury claims in England and Wales generally must be brought within three years under the Limitation Act 1980, so the record needs to outlast that window.
Some cases need longer. Incidents involving employees under 18 are best retained until they turn 21, since the three-year limitation clock for minors doesn't start until they reach adulthood. Exposure to substances with long-latency health effects — asbestos being the classic example — can justify retention for decades, since related illness may not surface for 20 or 30 years.
A digital record with no physical storage limit removes the guesswork. Pulse Operations's tamper-evident occurrence book is hash-chained (SHA-256) with a built-in integrity check, so records aren't just retained — they're provably unaltered from the moment they're logged, which matters as much for a three-year retention period as it does for a 30-year one.
Where can a business buy or download a compliant accident book?
The official accident book is BI 510, published by the HSE and sold through HSE Books. It is specifically designed to meet both the Social Security (Claims and Payments) Regulations 1979 and UK GDPR data protection standards, with individually detachable, confidential entry pages.
Employers aren't legally required to use the HSE's exact product — an "approved equivalent" that captures the same information and protects confidentiality is acceptable, which is why many organisations now use digital incident-logging systems instead. The key test isn't the format; it's whether the record captures every required field, protects individual privacy under UK GDPR, and survives for the statutory retention period without being lost, damaged or overwritten.
Digital vs paper: which accident book format works better?
Paper BI 510 books and digital incident-logging systems both satisfy the legal requirement, provided the record is complete, confidential and retained correctly — the choice comes down to how the business operates.
| Factor | Paper accident book | Digital accident/incident log |
|---|---|---|
| Legal compliance | Meets requirements if used correctly | Meets requirements as an "approved equivalent" |
| Confidentiality | Tear-out pages needed for GDPR | Access controls, per-user permissions |
| Multi-site visibility | Book stays on one site | Centrally visible in real time |
| Tamper evidence | Relies on physical custody | Can be hash-chained and audit-logged |
| Retention over years | Physical storage, risk of loss | Retained indefinitely, searchable |
| Speed of RIDDOR assessment | Manual review, often delayed | Flagged and assessed as it's logged |
For a single-site employer with a stable, on-premises workforce, a paper book can still work perfectly well. For multi-site security and FM operations — where officers move between sites, incidents happen at 3am with no manager present, and head office needs same-day visibility — a digital, centrally logged system closes the gap that paper structurally can't.
What are the penalties or risks of not keeping an accident book?
Failing to keep a compliant accident book exposes an employer to enforcement action, weakened legal defence, and reputational damage, even before any RIDDOR failure is considered. The HSE can issue improvement notices or prosecute under the Health and Safety at Work etc. Act 1974 where record-keeping failures form part of a wider safety management breakdown, and courts have discretion to draw adverse inferences where an employer cannot produce contemporaneous evidence of what happened.
The financial scale of workplace injury nationally underlines why this matters. 40.1 million working days were lost in 2024/25 due to work-related illness and injury, with an estimated £22.9 billion cost of injuries and ill health from 2023/24 working conditions, according to HSE (2026). An employer defending a personal injury claim with no accident record is defending it with no evidence at all — the claimant's version becomes the only version.
What common mistakes do employers make when recording accidents?
The most frequent accident book errors fall into a handful of predictable patterns. Recording opinions or blame instead of facts is the biggest one — "John was careless with the trolley" is not a compliant entry; "trolley wheel caught on uneven flooring, causing John to lose grip" is. Other common mistakes:
- Leaving fields blank — an incomplete entry undermines its evidential value months later.
- Delaying the entry — writing it up days later relies on memory, not fact.
- Storing the book insecurely — leaving it accessible to anyone, breaching UK GDPR confidentiality.
- Confusing accident book duty with RIDDOR duty — assuming a logged entry means the HSE has been notified, when it hasn't.
- Losing the paper record — a book left in a site cabin that changes hands or closes down.
- No named owner — nobody checking entries are being made consistently across shifts or sites.
Your accident book compliance checklist
- Confirm whether your organisation meets the 10-employee threshold under the Social Security (Claims and Payments) Regulations 1979.
- Use HSE's BI 510 or a GDPR-compliant approved equivalent, paper or digital.
- Name one person accountable for accident book upkeep across all sites.
- Train staff to record facts only — time, place, description, injury, treatment — never opinion or blame.
- Assess every logged incident against RIDDOR criteria within 24 hours of the entry.
- Report fatalities and specified injuries to the HSE without delay and within 10 days; report over-seven-day injuries within 15 days.
- Retain every entry for at least three years, longer for under-18s or long-latency exposure cases.
- Review accident book entries monthly to spot recurring causes, not just individual incidents.
FAQ
Is it a legal requirement to have an accident book in the UK?
Yes, for employers with 10 or more employees, under the Social Security (Claims and Payments) Regulations 1979. Smaller employers aren't specifically bound by this regulation but are still expected to demonstrate safety record-keeping under the Health and Safety at Work etc. Act 1974.
How many employees before you need an accident book?
An employer needs 10 or more employees before the specific statutory duty to keep an accident book applies, per Express Solicitors (2026). Below that threshold, keeping one is strongly advisable but not a distinct legal requirement under the 1979 Regulations.
What is the difference between an accident book and RIDDOR reporting?
The accident book records every workplace injury internally, however minor, while RIDDOR reporting only covers a narrower set of serious incidents that must be reported to the HSE. Fatalities and specified injuries need reporting within 10 days; over-seven-day injuries within 15 days, per HASpod (2026).
How long do you need to keep accident book records?
Employers must keep accident book entries for at least three years from the date of the incident, per Express Solicitors (2026). Cases involving under-18s or long-latency health risks such as asbestos exposure warrant much longer retention.
Can an accident book be kept electronically?
Yes, a digital or electronic system can serve as an "approved equivalent" to the HSE's BI 510 book, provided it captures the same required information and protects confidentiality under UK GDPR. Many multi-site employers now prefer digital logs because they give centralised, real-time visibility that a paper book left on one site cannot.
Is an accident book GDPR compliant?
An accident book is only UK GDPR compliant if individual entries stay confidential to the person involved, which is why HSE's BI 510 uses detachable, individually confidential pages. A book where every entry is visible to anyone who opens it fails this test, since accident details often count as special category health data.
What happens if an employer doesn't have an accident book?
An employer without a compliant accident book risks HSE enforcement action, a weakened position in any personal injury claim, and difficulty proving a pattern of health and safety management. Courts can draw adverse conclusions where no contemporaneous record exists to support the employer's account of an incident.
Managing incident records with Pulse Operations
Accident book compliance for a security or facilities operation isn't really a paperwork problem — it's a visibility problem. An incident on a mobile patrol run at 2am, or an assault reported by a door supervisor on a Saturday night, needs to reach the right person immediately, not when someone next visits the site cabin.
Pulse Operations's incidents and daily occurrence book module covers 18 incident types, logged by the officer on duty and visible to the control room the moment it's raised, with a hash-chained, tamper-evident audit trail behind every entry. This is the same discipline Pulse Operations applies to patrol verification across 24 sites for Priority First — the founding team's own London security and FM operation, where Pulse was built before being opened to other operators — because a record that can be challenged six weeks later is no record at all.
If your accident and incident logging still depends on a book in a cabin or a WhatsApp message to the office, get a demonstration of how Pulse Operations centralises it — pricing is published openly at /pricing, per operative, with unlimited sites and free admin and control-room seats.
