Quick answer
In Scotland, the three-year time limit for industrial disease claims runs from the 'date of knowledge' — usually the date of diagnosis — not from the date of exposure. This means claims can be made many decades after the original workplace exposure.
What is an Industrial Disease?
An industrial disease is a medical condition caused or materially worsened by exposure to harmful substances or conditions in the workplace. Unlike traumatic accidents, industrial diseases typically develop slowly — sometimes over decades — and may not be diagnosed until many years after the original exposure has ended.
Common Industrial Diseases in Scotland
- Mesothelioma — aggressive cancer caused by asbestos exposure
- Asbestosis — chronic lung disease caused by asbestos fibre inhalation
- Pleural plaques and pleural thickening — asbestos-related lung lining conditions
- Noise-induced hearing loss — from prolonged exposure to excessive noise
- Hand-arm vibration syndrome (HAVS) — from use of vibrating tools
- Vibration white finger — vascular disorder affecting the fingers
- Occupational asthma — triggered by workplace dust, chemicals or fumes
- Occupational dermatitis — skin conditions caused by workplace irritants
The Date of Knowledge: How Time Limits Work
The single most important legal concept in industrial disease claims is the "date of knowledge". The Prescription and Limitation (Scotland) Act 1973 allows the three-year period to begin from the date when the claimant first knew, or ought reasonably to have known, all of the following:
- That the condition was significant
- That it was attributable to conditions at their workplace
- The identity of their former employer or other responsible party
In practice, the date of knowledge is usually the date of formal diagnosis of the condition — or the date the worker received specialist medical advice linking their condition to their occupational exposure. This means that a worker who was exposed to asbestos in the 1960s but was not diagnosed with mesothelioma until 2024 would have until 2027 to bring their claim.
Claiming Against Former Employers
Many industrial disease claims involve former employers who may have ceased trading, merged with other companies, or dissolved. Fortunately, employers were legally required to hold employers' liability insurance. Even if the company no longer exists, it is often possible to trace the historic insurer and bring a claim against them. Specialist tracing services assist with this process.
Evidence in Industrial Disease Claims
- Medical diagnosis and specialist reports confirming the condition
- Employment history — where you worked, for how long, and what you were exposed to
- Witness statements from former colleagues confirming working conditions
- Occupational hygiene expert evidence in some cases
- Historical records showing the presence of asbestos, noise levels or other hazards
