Industrial Injuries Disablement Benefit Calculator 2026

IIDB is a tax-free weekly benefit for people disabled by a work accident or prescribed industrial disease. The amount depends on your assessed level of disablement (20%-100%). You do not need an NI record or to be means-tested.

Weekly rates 2025/26: 100% disablement: £236.10, 90%: £212.49, 80%: £188.88, 70%: £165.27, 60%: £141.66, 50%: £118.05, 40%: £94.44, 30%: £70.83, 20%: £47.22. Disablement below 20% does not qualify for most claims.

Over 70 prescribed diseases are listed, including: pneumoconiosis (coal dust), asbestosis and mesothelioma, occupational deafness (specific industries), vibration white finger (hand-arm vibration syndrome), occupational asthma, and many others. Full list at gov.uk.

Yes — IIDB can be paid even if you are still working. It compensates for the disability itself, not for loss of earnings. You can also receive IIDB alongside most other benefits.

If you are 100% disabled and need regular attendance from another person, you can receive Constant Attendance Allowance (CAA) on top of IIDB. CAA pays up to £219.80/week (exceptional circumstances rate). This is separate from Attendance Allowance.

A DWP medical examiner assesses your disablement by comparing your condition to a person of the same age and sex without the disability. They consider functional limitations, pain, and prognosis. You can request a review if you disagree.

There is no strict time limit for claiming IIDB, but delays can reduce backdated payments. Claims are backdated to the later of: 15 weeks after the accident/disease onset, or 5 years before the claim date.

If you die from a prescribed industrial disease, your surviving spouse/civil partner may be eligible for a 'Death Benefit' (a one-off lump sum under the Industrial Death Benefit scheme for deaths before 11 April 1988, or ongoing weekly payments for some circumstances).
