How long does a work injury claim take?

However, the time it takes to settle a work injury compensation claim can vary widely. Straightforward cases may resolve within a few months, while serious or disputed claims can take much longer. In some cases, settlement may take several years.

The two main factors affecting how long a claim will take are whether your employer accepts liability and the outcome of your medical assessment.

Typical settlement times

Since 2013, most claims valued at less than £25,000 follow the Pre-Action Protocol. This fast-track procedure is designed to speed up the process and reduce costs for lower-value claims. Most workplace accident claims start in this protocol.

Claims can take longer if liability is denied, if there are complex circumstances, or if the medical evidence requires ongoing assessments. Ultimately, there is no fixed formula. Your solicitor will update you at each stage and aim to reach a fair settlement as quickly as possible.

The Pre-Action Protocol timeline

Stage Time Limit
Stage 1 – Investigation
Defendant acknowledges receipt of Claim Notification Form (CNF)		 1 working day
Defendant responds to CNF 30 working days
Stage 2 – Negotiation
Evidence gathered and settlement pack prepared		 Varies
Defendant responds to settlement offer 15 working days
Extended negotiations if first offer not accepted +20 working days
Stage 3 – Hearing
If settlement cannot be reached, case proceeds to court		 Varies

Note: the portal process does not apply if liability is denied or contributory negligence is alleged.

Simple claims can settle in months, complex cases take longer. Medical evidence and liability decisions will dictate the pace. Keeping documents handy and replying quickly helps things move faster.

Factors that affect the length of a claim

Your employer admits liability

If your employer quickly accepts responsibility, your claim should settle sooner. However, settling too early can undervalue your claim. Your solicitor may advise against accepting an early or pre-medical offer, which insurers often make to limit payouts.

Your employer denies liability

If liability is denied, your solicitor will need to gather evidence such as witness statements, risk assessments, workplace records and possibly CCTV. In some cases, the Health and Safety Executive (HSE) may investigate. Insurers often deny liability initially but change position when strong evidence emerges. A court claim may be needed if denial continues, which will extend the process.

Medical reports

An independent medical examination is central to every claim. The report will set out the seriousness of your injuries, your prognosis for recovery and the effect on your life. If your condition develops or worsens over time, you may need further medical assessments. This may extend the process but ensures that you receive the right level of compensation.

Multiple or ongoing injuries

If you have multiple injuries or require ongoing treatment, several specialists may be involved. Because compensation is awarded on a full and final basis, your solicitor will likely recommend waiting until your prognosis is clear. Settling too early risks underestimating the true impact of your injuries.

Interim payments

For serious or long-running claims, it is sometimes possible to secure interim payments. These are advance payments of compensation that can help cover urgent costs such as medical treatment, rehabilitation or living expenses while the case is ongoing. Interim payments can reduce financial pressure and allow you to focus on recovery while your solicitor works to secure the final settlement.
