Savers scouring the market for a cash ISA will find the biggest month-on-month jump in the rates on offer in a decade, according to analysis by Moneyfacts.co.uk.
The financial information website said the average easy access ISA rate in April is 0.38% - up from 0.30% in March, making the 0.08 percentage point increase the biggest monthly rise for this type of account since April 2012.
In real terms, this means that someone saving £5,000 into an easy access cash ISA could typically make £15 in interest over a year if they do not dip into the pot based on March's average annual rate, increasing to £19 based on April's average rate.
