Why evidence matters

To succeed in a work injury claim, you must show that your employer or another party breached their duty of care and that this breach caused your injury. Gathering evidence early will make your claim stronger and reduce the chance of disputes. Courts, insurers and tribunals rely on documentary evidence, not just personal accounts.

Remembering to do the basics will really help your claim: Report your injury, take photos, get witness details, keep medical notes and receipts. Keep everything organised in one folder.

Types of evidence to collect

Evidence can come from many sources. The following are the most important:

  • Accident book entry: Every workplace with 10 or more employees must keep an accident book. Check your accident is recorded correctly.
  • Medical records: Visit a GP or hospital promptly. Medical notes confirm your injury and treatment timeline. See: NHS: View your GP health record.
  • Witness statements: Ask co-workers or others who saw the accident to write down what happened.
  • Photographs and video: Take photos of the accident site, hazards, and your injuries. If CCTV exists, your solicitor can request footage.
  • Employer policies and risk assessments: These documents can show whether safety procedures were followed.

Evidence checklist

Evidence Why it matters How to obtain
Accident book entry Proves the accident was reported at the time Ask your employer for a copy
Medical records Confirms the nature and severity of your injury Request from your GP or hospital
Witness statements Independent accounts that support your version of events Ask colleagues to write and sign statements
Photographs/CCTV Visual proof of hazards, conditions or injuries Take photos or ask your solicitor to request CCTV
Receipts and expenses Supports claims for lost income and special damages Keep tickets, invoices and receipts

Keeping financial records

To claim for lost income, travel costs or medical expenses, you need receipts and payslips. Without this evidence, your compensation for special damages will be reduced. See our guide on keeping records of expenses and losses.

How your solicitor can help

A personal injury solicitor can:

  • Request disclosure of workplace documents under legal rules.
  • Apply to the court for CCTV footage if your employer refuses to provide it.
  • Instruct medical experts to prepare reports on your injury.
  • Secure statements from witnesses if you are unable to do so.

Next steps after gathering evidence

Once you have collected initial evidence, speak to a solicitor. They will assess whether the evidence is strong enough to support a claim and explain how it can be used in negotiations or court. Acting quickly is vital as some evidence, like CCTV footage, may be deleted after a short period.
