UKI developed an industrial disease from work exposure. How long do I have to claim?
You generally have three years from the date you knew (or should reasonably have known) that your industrial disease was linked to your work to start a claim.
What the Law Says
The time limit for bringing a claim for an industrial disease in the UK is governed by the Limitation Act 1980, which sets out special rules for cases where harm develops gradually or is not immediately apparent.
Unlike accidents, where the limitation period usually starts on the date of injury, industrial diseases (e.g., asbestos-related illness, vibration white finger, occupational asthma) often take years to manifest and link to work. So the law uses a 'date of knowledge' test instead of the date of exposure.
Section 14 of the Limitation Act 1980 defines when the three-year time limit begins: it starts not from when you were exposed or even diagnosed, but from when you knew — or could reasonably have been expected to know — that the injury was significant, caused by someone else’s fault or breach of duty, and that the person responsible could be sued.
Statutory TextIn the case of actions for damages for negligence, nuisance or breach of duty (whether the duty exists by virtue of a contract or of a provision made by or under a statute or independently of any contract or any such provision) where the damage consists of personal injuries, the period of limitation shall be three years from the earliest date on which the plaintiff had both the knowledge required by subsection (1) and a right to bring an action.

What to Do
Get medical confirmation linking your condition to workplace exposure.
Record when you first suspected or were told the disease might be work-related — this may mark your 'date of knowledge'.
Seek legal advice as soon as possible — even if symptoms are recent, delays can risk missing the deadline.
If you’re unsure about the date of knowledge, ask a specialist solicitor to assess your circumstances — courts consider what a reasonable person would have known.
Act before the 3-year window closes — once expired, courts rarely allow claims unless exceptional circumstances apply.
