Class 3 NI contributions , adjustment to state pension.

I paid voluntary class 3 NI contributions in September 2023. Along with some credits for adult specified childcare this credited me with an extra 3 full years towards my state pension (I'm already in receipt of my pension). I received the 'automated receipt' for the money I'd paid by e-mail. I phoned DWP this morning for an update about my adjustment to my pension, and they asked if I'd had an actual letter from HMRC stating they'd received my payment, as they didn't seem to know anything about it! They said they'd look into it but suggested I also called HMRC. I think I gave up waiting on the phone. Would this take a long time? I did receive letters from HMRC stating I was successful with my extra 3 years credit claim. It all seems strange to me?

We were told on the phone (after a 45 minute wait to get through) that it would take around 8 weeks to update the NI record but nothing about how long the change in years would take to feed through to how much pension is actually received (stupidly we didn't ask this question) so would be interested to find this out too.

Hi Pancho99! alderton,
