Short answer: there is no single regulation that explicitly says “you must keep an accident book”.
Practical answer: UK employers are expected to record workplace accidents, and failing to do so puts you on the back foot legally, commercially, and operationally.
That distinction matters. This guide explains where the obligation actually comes from, how it is enforced in practice, and why “it’s not technically required” is a weak position to rely on.
The Legal Position in Plain English
There is no standalone law titled “The Accident Book Regulations”. That much is true.
However, UK health and safety law operates on duties and outcomes, not box-ticking paperwork. Employers are required to manage risks, investigate incidents, and demonstrate that they are doing so. Recording accidents is one of the primary ways this is evidenced.
The legal expectation flows from several overlapping duties, rather than a single rule.
Where the Obligation Comes From
Health and Safety at Work Act 1974
Under the Health and Safety at Work Act 1974, employers have a duty to ensure, so far as reasonably practicable, the health and safety of employees and others affected by their work.
If someone is injured at work, that duty does not end when first aid is given. Employers are expected to be able to show:
that the incident was acknowledged
that it was assessed properly
that reasonable steps were taken to prevent recurrence
Without a record, there is no evidence any of this happened.
In practice, an accident book is how that duty is demonstrated.
RIDDOR Reporting Duties
Certain serious incidents must be reported to the regulator under RIDDOR.
To know whether an incident is reportable, employers must first record what happened, when, and to whom. That initial record is usually an accident book entry.
While RIDDOR does not require you to keep an accident book by name, it assumes that a reliable internal recording system exists. Without one, compliance becomes guesswork.
Civil Claims and Employment Law
In personal injury claims, employment tribunals, and insurance disputes, accident records are routinely requested as evidence.
If an employer cannot produce a contemporaneous record of an incident, it is often taken as an indication that:
the incident was not handled properly
safety procedures were weak
records were poorly managed
Courts and insurers are not interested in technical loopholes. They expect employers to behave reasonably. Reasonable employers keep accident records.
What the HSE Expects in Practice
The Health and Safety Executive does not publish guidance saying “accident books are optional”.
Instead, its guidance consistently refers to:
recording injuries
keeping incident records
maintaining evidence of investigations and controls
During inspections, HSE officers regularly ask to see accident records. An employer who responds with “we don’t keep one because it’s not explicitly required” is not starting from a strong position.
The expectation is clear, even if the wording is indirect.
Does Every Business Need an Accident Book?
If your business:
employs staff
operates a workplace
allows public access
manages contractors or agency workers
then you are expected to record accidents when they occur.
This applies to:
offices
shops
warehouses
schools and colleges
care settings
hospitality venues
manufacturing sites
multi-site organisations
Size is not a defence. If an accident happens, it should be recorded.
What Happens If You Don’t Keep Accident Records?
Failing to record accidents does not automatically result in a fine. The risk lies in what happens next.
If there is:
an HSE inspection
an insurance claim
an employee dispute
a civil claim months or years later
and you have no accident record, your position is weakened immediately.
You may struggle to show:
what actually happened
whether the injury was work-related
what action was taken
whether risks were reviewed
In most disputes, the absence of records works against the employer, not the other way around.
Paper vs Digital Accident Books and Legal Compliance
The law does not require accident records to be kept on paper. Digital records are fully acceptable, provided they are accurate, secure, and accessible.
In fact, paper accident books increasingly create compliance issues, particularly around data protection and access control.
Digital accident books often make it easier to demonstrate that:
records are complete
entries are consistent
access is restricted appropriately
information can be retrieved quickly when requested
From a legal standpoint, how you record accidents matters far less than whether you can produce a reliable record when it is needed.
The Reality for UK Employers
So, is an accident book a legal requirement in the UK?
Not explicitly.
But in practice, yes.
UK employers are expected to record workplace accidents as part of their wider legal duties. An accident book is the accepted, recognised way of doing that.
Choosing not to keep one does not remove your obligations. It simply removes your evidence.
Key Takeaway
If an accident occurs and you cannot show a clear, factual record of what happened, you are exposed. Legally, operationally, and reputationally.
For UK employers, the sensible position is not to ask “do I technically have to?”
It is to ensure you can confidently demonstrate compliance when it matters.
