Yes, you can still claim Personal Independence Payment (PIP) while on maternity leave. PIP is a non-means tested benefit designed to support individuals with disabilities or long-term health conditions, so your maternity leave status does not affect your eligibility. However, it's important to ensure that you continue to meet the qualifying criteria for PIP during this time. If you have any concerns or specific circumstances, consider consulting a regulated adviser or visiting the official gov.uk page for more detailed information.
