Having applied online a few weeks ago, i received two letters in the post today (dated 6th Feb 2026).
One letter says "Thank you for applying to pay voluntary Class 3 contributions. For the period 09/04/2006 to 05/04/2025 the amount due is £1,883.70", followed by a small amount of info on various methods of payment.
The second letter says "We've looked at the information on your application and have decided you can pay voluntary Class 2 National Incusrance Contributions by a yearly payment.......Our records show you have 6 qualifying years of NIC's up to 5 April 2025". It then provides a table of years with amounts of payment required which i've summarised below.
| Start | End | Class | Amount |
| 2006 | 2007 | 3 | 824.20 |
| 2007 | 2008 | 0 | Full Year |
| 2008 | 2009 | 0 | Full Year |
| 2009 | 2010 | 0 | Full Year |
| 2010 | 2011 | 2 | 154.35 |
| 2010 | 2011 | 3 | 47.55 |
| 2011 | 2012 | 2 | 163.80 |
| 2012 | 2013 | 2 | 163.80 |
| 2013 | 2014 | 2 | 163.80 |
| 2014 | 2015 | 2 | 166.95 |
| 2015 | 2016 | 2 | 163.80 |
| 2016 | 2017 | 2 | 163.80 |
| 2017 | 2018 | 2 | 163.80 |
| 2018 | 2019 | 2 | 163.80 |
| 2019 | 2020 | 2 | 166.95 |
| 2020 | 2021 | 2 | 163.80 |
| 2021 | 2022 | 2 | 158.60 |
| 2022 | 2023 | 2 | 163.80 |
| 2023 | 2024 | 2 | 179.40 |
| 2024 | 2025 | 2 | 179.40 |
| Total | 3,351.60 | | |
A phone number for the "Future Pension Centre" is provided which they say to call before making a payment. I'll do this tomorrow, but just wanted to better understand my options before that call.
1) Any idea how the figure of £1,883.70 in the first letter relates to the figures in the second letter? The total of Class 3 in the more detailed letters is £871.75 and i can't see an obvious summation of years that gets to that total.
2) When they say "you have 6 qualifying years of NIC's up to 5 April 2025", does this mean i can make voluntary contributions for 6 additional years, or that for some reason they think i have 6 years already and i can make voluntary contributions for all the years on the letter? {2007 - 2010 are absent from the table on the letter, i've inserted them above for (hopefully) clarity.
3) Assuming i can only make voluntary contributions for 6 years retrospectively, can i choose which ones? Specifically can i choose not to pay for 2006-2007 @ £824, and choose to pay from 2010-11 to 2015-16 at the lower class 2 rates?
4) The letter also states "From 6 April 2026, Voluntary NIC's can no longer be paid at the Class 2 rate", so if i have 3 full years, and i pay retrospectively for 6 more, then i'll need to pay Class 3 for 2025-6 in due course to get to the minimum 10 years?
I would appreciate any clarification/correction of my understanding on the points above.
