Yes, you can work and claim Personal Independence Payment (PIP); having a job or earnings does not automatically prevent an award. PIP is based on how a long-term health condition or disability affects your daily living and mobility, rather than whether you are employed. You will need to explain the difficulties you have, how often they affect you and any help or aids you need. The Department for Work and Pensions makes the decision after considering your claim and assessment, so check the latest guidance on GOV.UK for the eligibility rules.
