An occupational COPD claim in the UK arises when chronic obstructive pulmonary disease is caused or significantly worsened by workplace exposure to dust, fumes or chemicals because your employer failed to comply with the COSHH Regulations 2002. Compensation is valued under JCG Chapter 7(D) for lung disease. You can claim even if you also smoked. IIDB may be available as a separate state benefit. The time limit runs from the date of knowledge.
COPD is the UK's third leading cause of death, and a significant proportion of cases are caused or worsened by workplace exposures. The HSE estimates that thousands of COPD deaths each year have an occupational component. Industries including mining, construction, welding, foundry work and grain handling have historically exposed workers to dangerous levels of respirable dust and fumes. This guide explains how occupational COPD compensation claims work. We are an independent information service, not a law firm.
What is occupational COPD?
COPD is a group of lung conditions including chronic bronchitis and emphysema that cause progressive, irreversible airflow obstruction. Occupational COPD is COPD caused or materially contributed to by inhaling harmful substances at work: coal dust, silica dust, grain dust, wood dust, cotton dust, welding fumes, diesel exhaust, and chemical vapours. It is distinct from purely smoking-related COPD, though many patients have both occupational and smoking contributions.
Common workplace causes
| Industry | Exposure |
|---|---|
| Coal mining | Coal dust (prescribed disease D12) |
| Construction | Silica dust, cement dust, wood dust |
| Welding | Welding fumes (now recognised as a carcinogen by HSE) |
| Foundry work | Metal fumes and silica sand dust |
| Agriculture and grain handling | Grain dust, organic dust |
| Textile manufacturing | Cotton dust (byssinosis) |
| Baking | Flour dust |
| Woodworking | Hardwood and softwood dust |
✓ Smoking does not prevent a claim
If workplace exposure materially contributed to your COPD, you have a valid claim even if smoking also played a role. An expert respiratory report will assess the relative contributions. The employer pays for its share of the damage.
Employer duties
Under COSHH 2002, employers must prevent or control exposure to respirable dusts and fumes. Workplace Exposure Limits for common dusts (e.g. respirable dust 4 mg/m3, inhalable dust 10 mg/m3) must not be exceeded. Employers must provide dust suppression, LEV, RPE where needed, exposure monitoring and health surveillance.
Compensation
- General damages under JCG 17th edition (2024), Chapter 7(D), ranging from lower awards for mild breathlessness to substantial sums for severe COPD with oxygen dependency, inability to work and shortened life expectancy.
- Special damages for lost earnings, home oxygen, inhalers and medication, pulmonary rehabilitation, care, travel and home adaptations.
Living with occupational COPD
COPD is a progressive, incurable condition. Compensation must reflect the lifelong impact:
- Breathlessness. As the disease advances, even simple activities like walking, dressing or climbing stairs become exhausting. Many patients eventually need supplemental oxygen.
- Exacerbations. Acute flare-ups triggered by chest infections can require hospitalisation and IV antibiotics. Each exacerbation causes further irreversible lung damage.
- Employment. Most moderate-to-severe COPD patients are unable to continue physical work. The loss of future earnings can be the largest element of the claim, calculated using Ogden Tables and expert accountancy evidence.
- Mental health. Breathlessness, loss of independence and inability to work frequently cause depression and anxiety, which are independently compensable.
- Care needs. Severe COPD patients need help with daily activities, and some eventually require residential care. A care expert will assess current and future care needs and costs.
Industrial Injuries Disablement Benefit
Chronic bronchitis and emphysema in coal miners is prescribed disease D12. Other forms of occupational COPD may also qualify. IIDB is separate from your civil claim. See compensation and benefits.
Evidence
- Lung function tests (spirometry showing obstructive pattern).
- Chest X-ray or CT scan.
- Expert respiratory medicine report linking COPD to workplace exposure.
- Full employment history with dates, employers and exposure details.
- COSHH assessments and exposure monitoring data.
- GP and hospital records documenting symptoms and treatment.
Time limits
Three years from the date of knowledge (Limitation Act 1980, s.14). See our time limits guide.

Frequently asked questions
What is occupational COPD?
Chronic obstructive pulmonary disease caused or significantly worsened by workplace exposure to dust, fumes, vapours or gases. It includes chronic bronchitis and emphysema. Unlike smoking-related COPD, occupational COPD is caused by the employer's failure to control inhaled hazards at work, and it is compensable.
Can I claim if I also smoked?
Yes. Smoking does not prevent a claim for occupational COPD. If workplace exposure materially contributed to your COPD, you have a valid claim even if smoking also played a role. The court may apply a discount for the smoking contribution, but the employer still pays for its share of the damage. The key evidence is an expert respiratory report assessing the relative contributions.
Which jobs cause occupational COPD?
Coal mining, quarrying, construction, welding, foundry work, grain handling, textile manufacturing, baking, woodworking and any occupation involving prolonged exposure to respirable dust, fumes or chemical vapours without adequate controls.
How much compensation for occupational COPD?
It depends on severity. The JCG 17th edition Chapter 7(D) covers lung disease, with brackets from lower awards for mild breathlessness to very substantial sums for severe COPD with oxygen dependency and major disability. Special damages for lost earnings, medication, treatment, home oxygen and care are added on top.
Can I claim IIDB for occupational COPD?
Yes, if your COPD qualifies as a prescribed disease. Chronic bronchitis and emphysema in coal miners is prescribed disease D12. Other occupational COPD may qualify under general industrial disease provisions depending on the exposure. IIDB is a state benefit separate from your civil claim.
How long do I have to claim?
Three years from when you knew or should have known your COPD was caused by workplace exposure, under the Limitation Act 1980 section 14. Because COPD develops gradually, this is often the date of diagnosis and a doctor's confirmation that it was work-related.
What if my employer has closed down?
You may still claim against the employer's liability insurer. The Employers' Liability Tracing Office (ELTO) can help locate historical policies. Even if the company no longer exists, the insurer remains liable.
