Check if you could pay to fill gaps and boost your State Pension on Government Gateway, where you’ll also be able to make payments via bank transfer.
Voluntary contributions may not always boost your State Pension – if you’re unsure, call the Future Pension Centre if you’re under State Pension age, or the Pension Service if you’ve reached State Pension age. Phone lines are extremely busy – so be patient and try calling in the early morning or late afternoon if possible.
If you are unable to speak to anyone, you can ask DWP to call you back to discuss paying voluntary National Insurance contributions If you submit a request by the 5 April 2025 deadline, you will still be able to pay voluntary National Insurance contributions after the deadline has passed.
