Having a disability does not usually increase your State Pension automatically. Your entitlement is mainly based on your National Insurance record, although some credits may help build qualifying years if you have been unable to work or have cared for someone. If you are below State Pension age, benefits such as PIP or ESA may be relevant, depending on your circumstances; after State Pension age, Attendance Allowance could be worth checking. Use the State Pension forecast on GOV.UK to review your record and seek advice from a benefits adviser if anything appears missing.
