Yes, a pensioner couple can both claim Personal Independence Payment (PIP), but each claim is assessed individually based on their personal circumstances and needs. PIP is designed to help with the extra costs of living with a long-term health condition or disability. Eligibility depends on how those conditions affect daily living and mobility, rather than age. It's advisable to check the official gov.uk page on PIP for detailed guidance and to consider consulting a regulated welfare advisor for personalised assistance.
