Apologies if this has already been posted but the deadline to plug any NI contribution gaps is closing on 5th April and gaps in contributions could have a significant impact on your state pension so well worth looking at.
It may require you to pay for top-up (apparently not always but not applicable to me) but I was shocked to find I had gaps of a few years even though was employed & paying tax & NI!
