You may be able to claim if your carpal tunnel syndrome (CTS) was caused or made worse by your work, for example through regular use of vibrating or percussive hand tools or frequent, repeated bending of the wrist, and your employer failed to manage the risk. HSE describes CTS as compression of the median nerve, which controls sensation and movement in the hand, and notes that it is not always caused by work. In England and Wales you normally have three years from when you knew the condition was significant and linked to your work. You may also qualify for Industrial Injuries Disablement Benefit under prescribed disease A12.
Carpal tunnel syndrome causes tingling, numbness, pain and weakness in the hand, and it can make gripping tools or doing fine work difficult. It is not always caused by work, so a claim turns on showing that your job caused or worsened the condition and that your employer should have done more. This guide covers the work activities official rules link to CTS, what employers are required to do, the evidence that matters, and the time limit. We are an independent information service, not a law firm.
What carpal tunnel syndrome is
HSE explains that CTS is caused by compression of the median nerve, which controls sensation and movement in the hand. Its symptoms include tingling, numbness, pain and weakness in the hand, which can interfere with work and everyday tasks. HSE lists CTS among the upper limb disorders that work can cause or make worse, alongside tendonitis, tenosynovitis and hand-arm vibration syndrome, and says people with upper limb disorders usually completely recover if the problem is recognised early and treated appropriately.
CTS is often discussed alongside repetitive strain injury (RSI) and vibration white finger. For benefits the distinction matters: CTS has its own entry, A12, in the list of prescribed diseases, separate from the vibration white finger entry, A11.
When work is linked to CTS
| Work activity | Where it appears | What the rule says |
|---|---|---|
| Hand-held powered tools that vibrate, such as sanders, grinders or chainsaws | IIDB prescribed disease A12; RIDDOR regulation 8 | A12 covers use of such tools at the time the symptoms first develop. Employers must report a CTS diagnosis where the work involves regular use of percussive or vibrating tools. |
| Repeated bending of the wrist | IIDB prescribed disease A12 | Repeated palmar flexion and dorsiflexion of the wrist for at least 20 hours a week, for at least 12 months in the 24 months before symptoms began, where repeated means once or more every 30 seconds. |
| Typing or similar repetitive movements | HSE guidance on RIDDOR | CTS is not reportable under RIDDOR where the work involves typing or similar repetitive movements. |
These rules decide benefits and reporting, not whether a court claim succeeds. A civil claim needs evidence that your work caused or worsened the CTS and that your employer fell short of what it should have done. HSE's list of risk factors for upper limb disorders includes prolonged repetitive work, awkward postures, sustained or excessive force, long tasks without suitable rest breaks, and working with hand-held power tools for long periods.
What your employer should have done
For vibrating tools, the Control of Vibration at Work Regulations 2005 require employers to eliminate the risk from vibration at source or, where that is not reasonably practicable, reduce it to as low a level as is reasonably practicable. HSE's employer guidance gives a daily exposure action value of 2.5 m/s² A(8), a clear risk requiring management, and a daily exposure limit value of 5 m/s² A(8), a high risk above which employees should not be exposed. Where the risk assessment shows a risk to health, or exposure is likely to reach the action value, employers must provide suitable health surveillance and keep a health record for each employee under it.
For repetitive work, HSE says employers must do a risk assessment, protect workers from injury from repetitive work, protect them from the health risks of display screen equipment and from exposure to vibration, and make sure they know how to report any injuries. HSE also tells employers to encourage workers to report signs and symptoms early, before they become more serious.
One legal detail: since 1 October 2013, section 47 of the Health and Safety at Work etc. Act 1974 has provided that breach of a duty in health and safety regulations is not actionable except to the extent that regulations provide. If your exposure spans that date, ask your solicitor how it affects the way the claim is put.
Evidence for a carpal tunnel claim
- Diagnosis: GP and specialist records, including any nerve tests and treatment.
- Your tasks: the tools you used, for how long each day, and how often your wrist repeated the same movement. The A12 test is framed in hours per week and a 30-second repetition rate, so a diary or job description helps.
- Employer records: vibration risk assessments, tool vibration data, job rotation and health surveillance records. Employers must keep a health record for each employee under surveillance.
- Reports: an accident book entry, and whether the employer made a RIDDOR report after a CTS diagnosis linked to vibrating tools.
- Witnesses: colleagues who did the same work.
Under the Pre-Action Protocol for Disease and Illness Claims, which covers injuries that take the form of an illness or disease, the employer should provide copies of occupational records within 40 days of a request, at no cost.
Industrial Injuries Disablement Benefit (A12)
GOV.UK describes Industrial Injuries Disablement Benefit as help if you are ill or disabled from an accident or disease caused by work. CTS is prescribed disease A12 where you used hand-held powered tools whose internal parts vibrate when the symptoms first developed, or did the repeated wrist movement described above. You cannot claim IIDB for work you did while self-employed.
IIDB is separate from a compensation claim. The Compensation Recovery Unit recovers social security benefits in certain compensation cases; see our guide to compensation recovery and benefits.
Time limits
In England and Wales a claim must normally be started within three years of the injury or, if later, your date of knowledge: when you first knew the condition was significant, that it was attributable to what your employer did or failed to do, and who was responsible. HSE notes that vibration-related symptoms may come and go before becoming prolonged or permanent, which is one reason the date of knowledge often matters. The law also counts what you could reasonably have found out, including with medical advice it was reasonable to seek. Scotland and Northern Ireland also use three-year periods with a knowledge test.

Frequently asked questions
Can I claim for carpal tunnel syndrome caused by work?
Possibly, if your work caused or worsened the condition and your employer failed to manage the risk, for example from vibrating tools or frequent repeated wrist bending. You need medical evidence linking the CTS to your work and evidence of what your employer did or did not do. In England and Wales the time limit is normally three years from your date of knowledge.
Can I claim for carpal tunnel from typing?
It is harder. HSE says CTS is not reportable under RIDDOR where the work involves typing or similar repetitive movements, and the A12 benefit rule only covers vibrating tools or repeated wrist bending for at least 20 hours a week. A civil claim would depend on expert medical evidence about the cause and on what your employer did to manage the risk.
Is carpal tunnel syndrome a prescribed disease?
Yes, it is prescribed disease A12 for Industrial Injuries Disablement Benefit, where the work involved hand-held vibrating powered tools when symptoms first developed, or repeated wrist flexion and extension of at least once every 30 seconds for at least 20 hours a week over at least 12 of the 24 months before symptoms began.
How long do I have to make a carpal tunnel claim?
In England and Wales you normally have three years from the date you first knew the condition was significant and linked to your work. A court can allow a late claim if it would be equitable, but that is discretionary. Scotland and Northern Ireland also have three-year periods.
What should my employer have done to prevent it?
For vibrating tools, employers must eliminate or reduce the risk from vibration, keep exposure below the legal limit value and provide health surveillance where there is a risk to health. For repetitive work, HSE says employers must assess the risk, protect workers from injury and make sure they know how to report symptoms.
Is carpal tunnel syndrome the same as RSI?
Not exactly. HSE lists carpal tunnel syndrome as one of several upper limb disorders that work can cause or make worse, alongside conditions such as tendonitis and tenosynovitis. Our RSI claims guide covers those related conditions.
