Self assessment required or not?

I am retired and my only income is from my state pension and interest from several bank accounts and fixed rate bonds. I only started receiving my state pension payments this year which up to April totalled just under £2,000. I also received during the last tax year approx £20,000 in interest so my total income was a little over £22,000. As the banks declare all payments to HMRC would I receive a bill for any taxes owed or am I required to file a SA for the last tax year showing all income.?
