He explained that putting more money into ISAs now can help savers get more value from their money, as well as offer better protection against future financial hurdles.

However, most people don’t pay tax on savings anyway. Since 2016, the personal savings allowance (PSA) means basic rate (20 percent) taxpayers can earn £1,000/year interest in any savings tax-free – while the limit is £500/year for higher rate (40 percent) taxpayers.So currently savers would need over £29,000 (£14,500 at higher-rate tax) in top easy-access savings before they earned enough interest to be taxed, over £22,000 (£11,000) in the top two-year fix.

Though if interest rates rise further, those amounts will get smaller.
Normal savings usually pay slightly more than cash ISAs. Those who aren’t bigger savers could just go for the highest rates, which means top savings, not ISAs.

If someone has under £20,000 – they could always just put that in an ISA in future – there’s no harm going for higher rates now.
