Savers could be handed their strongest fixed return in years as ISA rates climb to their highest rates since January 2024, according to the latest Moneyfacts UK Savings Trends Treasury Report.
The average longer-term fixed ISA rate rose to 4.27%, its highest since January 2024, when it reached 4.32%.
The average one-year fixed ISA rate rose to 4.24%.
The average one-year fixed savings rate rose to 4.23%, its highest since November 2024 (4.24%). The longer-term average fixed savings rate jumped to 4.25%, its highest figure in over two years (January 2024 4.46%).
Caitlyn Eastell, personal finance analyst at Moneyfacts, said: “The fixed rate savings market is shifting in favour of ISA savers, with average one-year and long-term ISA rates now moving ahead of their non-ISA counterparts.
“Fixed-rate savers may be able to lock in some of the strongest returns seen in years, with average long-term ISAs and non-ISA rates hitting their highest levels since January 2024, while the average one-year non-ISA also reached highs not seen since November 2024.”
She said overall product choice continues to beat all-time highs, rising to 2,617 savings deals (including ISAs). Excluding ISAs, product count rose to 1,871, the highest number of non-ISA products since Moneyfacts records began in February 2007. The number of cash ISAs rose to 746.
The number of accounts paying above Base Rate at £5K rose to 1,412, its highest since July 2012, when there were 1,428.
The average easy access rate remained unchanged at 2.53%. The average notice rate also remained unchanged at 3.40%. The average easy access ISA rate remained unchanged at 2.72%, while the average notice ISA fell to 3.31%.
The Moneyfacts Average New Savings Rate has risen for the sixth time running to 3.6%. Over the past year the rate has risen from 3.50% to 3.60%.
Ms Eastell, said: “For a saver with £20,000, the average one-year ISA rate would give around £848 in interest over a year, compared with £846 in a non-ISA account. While the £2 difference may seem small, for a higher-rate taxpayer with a £500 Personal Savings Allowance, the ISA could leave them around £138 better off, with the full £848 interest kept compared with around £708 from the non-ISA after tax. On larger balances, the benefit of switching becomes even more apparent.”
