Good Morning, I am about 6 years short of my full pension contributions and am due to receive my state pension in October 2029. I am happy to make up the difference by buying those years however I still have a small part time job that pays weekly and as such I still make small NI contributions through this job (approx £170 per year). Do these contributions still count towards any state pension I will receive or are they so small they won’t really count. Many Thanks
