There is no separate Welsh State Pension: people living in Wales generally qualify under the same UK rules as elsewhere. Your entitlement mainly depends on your National Insurance record and State Pension age; under the new State Pension rules, you usually need at least 10 qualifying years for any payment and 35 for the full rate, although transitional rules may apply. You can check your State Pension forecast and National Insurance record on GOV.UK. You normally need to claim, and your payment may affect other benefits or tax depending on your circumstances.
