Being a single parent does not automatically qualify you for Personal Independence Payment (PIP), and it does not rule you out. PIP is assessed on how a long-term health condition or disability affects your daily living and mobility activities, rather than your income, savings or family status. Caring for a child may be relevant when explaining how your condition affects you, but the decision is based on your individual difficulties and supporting evidence. Check the latest guidance and apply through the official GOV.UK PIP page; you may also be able to claim other support separately.
