Filling NI gaps

I have paid 34 full years and due to ill health no longer work. My forecast is 175.85 - if I pay the outstanding year will this go up to the forecast of 213.77? It’s impossible to get through on the phone - and the online platform says because I am not currently working (contributing) I cannot make a payment online so need to be able to speak to someone!

Hi Julia62,
You will need to speak to the DWP (Department for work and Pensions) to see if paying voluntary contributions will increase your state pension and the actual
mount it goes up to if you have not done so already.
If you have ensured the year/s to pay will make an increase with DWP you will need to speak to the HMRC National Insurance helpline if the online platform
prevents you from making a payment. They will be able to check your national insurance record and advise how to pay.
