You may be able to claim against your employer if their negligence or a breach of health and safety duties contributed to your injury, but an accident at work does not automatically mean compensation is payable. Report the incident, seek medical attention and keep evidence such as photographs, witness details and records of lost earnings. Most personal injury claims must generally be started within three years, although exceptions can apply. Consider speaking to a solicitor regulated by the SRA, who can assess your circumstances and explain the likely costs and evidence needed.
