Gaps on your NI record could reduce the value of your State Pension pot or mean you are not eligible. By making voluntary contributions, you can fill in those gaps and ensure you have sufficient qualifying years on your NI record.
Another option that may allow you to boost your retirement income is to delay taking your State Pension.
The value of the UK State Pension increases by 1% for every nine weeks it's deferred. By deferring your pension for two years, it would increase by over 11%.
