Industrial Injuries Benefits

You may qualify for Industrial Injuries Disablement Benefit if you were disabled by:

• An accident at work while you were an employed earner (not self-employed)
• A prescribed industrial disease caused by your employment — the list includes conditions such as vibration white finger, occupational deafness, pneumoconiosis (from coal dust), asbestosis, mesothelioma, and many others

You must have been working as an employee at the time. Self-employed workers cannot claim IIDB. The accident or disease must have occurred in Great Britain, or you must have been working for a UK employer when it happened abroad in certain circumstances.

IIDB is not available for road traffic accidents during a commute unless the accident occurred on your employer's premises or during travel that was a formal part of your duties.

The DWP uses a medical assessment to determine the degree of disability caused by your work-related condition, expressed as a percentage. The key thresholds are:

• At least 14% disability: Required for most IIDB claims
• At least 1% disability: For certain specific prescribed diseases
• 100% disability: Attracts the maximum weekly rate

The assessment only considers the disability caused by the work accident or disease — not any pre-existing conditions. If you have a pre-existing condition that has been worsened by a work-related condition, the assessors will consider the degree of worsening attributable to the work injury.

The weekly IIDB rate in 2025/26 ranges from around £39 per week (14% disability) to £217.10 per week (100% disability). Awards can be for a fixed period or for life depending on the nature of the condition.

In addition to IIDB, other benefits and payments may be available for industrial injuries:

• Constant Attendance Allowance (CAA): An additional payment for IIDB claimants who need daily care as a result of their industrial injury and are assessed at 100% disability.
• Exceptionally Severe Disablement Allowance: An additional payment for those receiving the highest rate of CAA.
• Reduced Earnings Allowance (REA): For claimants who became disabled before 1 October 1990 and cannot return to their regular occupation as a result.
• Diffuse Mesothelioma Payment: A one-off lump sum payment scheme for mesothelioma sufferers who cannot claim compensation from an employer (for example because the employer no longer exists).

Citizens Advice and specialist industrial injuries charities can help you identify all the benefits you may be entitled to.

IIDB decisions — whether about the assessment of disability level, the qualifying condition, or eligibility — can be challenged through the standard DWP appeals process.

Requesting a Mandatory Reconsideration: If you disagree with the degree of disablement assessed, or if your claim has been refused on eligibility grounds, you have one month from the decision letter to request a Mandatory Reconsideration. Set out specifically which aspect of the decision you believe is wrong and provide any additional medical evidence supporting your view. For example, if the DWP assessed your disability at 14% and you believe it should be higher, obtain a report from your treating clinician commenting on the functional impact of the condition and why a higher assessment percentage is warranted.

Prescribed diseases — special rules: For prescribed industrial diseases, the assessment can be particularly technical. Some prescribed diseases require the claimant to have worked in a specified occupation for a minimum period. For example, occupational deafness (PD A10) requires ten years working with qualifying noise-creating tools or machinery. If your claim is refused on occupational grounds, gather employment records, payslips, or witness statements from former colleagues confirming the nature of your work.

Interaction with Universal Credit: IIDB counts as unearned income for Universal Credit and will reduce your UC award pound for pound. This means that while IIDB increases your overall income, the net gain within a UC claim is offset by the UC reduction. However, IIDB is still worth claiming because it adds directly to total household income in ways that non-means-tested PIP does not — specifically, PIP does not reduce UC but IIDB does, making the combination of PIP and IIDB preferable to IIDB alone for UC claimants who also have a qualifying disability.

Interaction with Personal Injury Compensation: If you receive a civil compensation payment from your employer or an insurer in respect of the same industrial accident or disease, the DWP may have a right to recover IIDB payments already made from the compensation via the Compensation Recovery Unit (CRU). The insurer will check the CRU register before paying any settlement. This does not prevent you from claiming IIDB, but it means the practical financial outcome of receiving both may be less than the sum of the two figures suggests. Personal injury solicitors routinely deal with CRU deductions — ensure your solicitor is aware you are also claiming IIDB.

Scotland and Wales: IIDB is a reserved benefit administered by the DWP across Great Britain on identical terms. However, some prescribed industrial diseases may have different prevalence in Welsh mining communities or Scottish heavy industries. Citizens Advice in Wales and Scotland has specialist knowledge of industrial disease claims in those regions, including access to historical occupational health records.
