This is shocking - 13p return in the year per £100 deposited in one high-street ISA (0.13%). Many now offering just 0.20% interest even after base rates have been raised by 0.5% in the last 13 months.
"The worst cash Isa in Britain paid just 13p interest for every £100 saved into it this year, analysis for The Sunday Times reveals. The Santander Easy Isa paid £26.58 interest for anyone who had £20,000 in the account on January 1, 2018. The account paid 0.1% until September, when it was increased to 0.2% after the Bank of England’s base rate went up to 0.75%."
