There is an estimated £90.7bn being held in adult fixed term savings accounts that are due to mature during Q2 this year, according to new analysis by Paragon Bank.

The group reported that three million accounts are due to mature between April and June, highlighting the scale of decisions facing savers in the coming months.

Paragon’s analysis of CACI data revealed that in April, more than 1.2 million fixed rate accounts are scheduled to mature, representing over £36bn of savings. Cash ISAs will dominate the maturities in April, with 840,137 one-year fixed rate ISAs maturing, worth £22.9bn.

A further one million accounts worth £31bn will mature in May, followed by around 730,000 accounts holding £23bn in June. Again, one-year ISAs will dominate, with £18.8bn and £12bn maturing respectively over these months, across 676,445 and 424,621 accounts.

Head of savings at Paragon, Andrew Wright, said: “A significant number of fixed rate accounts are set to mature over the next quarter, reflecting the bumper 2025 ISA season.

“One-year fixed-rate savings accounts dominate maturities over the period, with cash ISAs leading the charge marking the start of the new tax year. These accounts will be maturing into a competitive market, with savings rates increasing in recent weeks.”

Wright added that savers are considering longer fixed terms to secure attractive rates across a number of years.

“The market has seen a marked increase in the popularity of longer-term fixed rates in recent months, with the value of deposits held in five-year accounts increasing by nearly a third in 2025,” he continued.

“While shorter term fixes continue to attract the largest volumes overall, the increase in balances in longer-dated accounts indicates savers looked to take advantage of interest rates and reduce long-term risk of unstable interest rates.”
