Cash ISA

NatWest, RBS and Ulster Bank are banning introductory bonus rates to get back to basics with simpler products. But MoneySavingExpert.com creator Martin Lewis says the move could result in even lower returns and less certainty for savers.

If you're an HSBC current account holder, you can now get up to 1.6% AER interest on your savings with the bank's new Isa – but it's not a market-leading deal.

Update: 6 February 2014: The RBS Group has confirmed that any missing interest has now been credited to affected NatWest and RBS customers' Isa accounts.

Savers can put a little more money into cash Isas from next April, Chancellor George Osborne said today.

Three million NatWest and RBS Isa account holders will have their rates cut or boosted, as the banks are moving anyone with an old Isa to a newer deal.

Premium Bond holders will have their chances of winning slashed next week, as NS&I is cutting the annual 'interest rate' on the prize fund.

The new tax year began on Saturday, but savers who want to put their money into a new Isa should do it quickly, as some of the best buys have already been pulled.

Last year's top cash Isa rates have plummeted, so act now to make sure you're not losing out on hundreds of pounds.

Coventry Building Society is closing its best buy cash Isa, so act now if you want to take advantage of the account, which currently pays 2.8% AER, with a 0.6% bonus for a year.
