The Santander Edge Saver offers seven per cent AER / 6.78 per cent gross (variable) interest on balances up to £4,000.

This includes a 2.50 per cent AER (variable) bonus rate which is available for the first 12 months from opening the account – and is exclusive for Santander Edge current account customers.

Another option is their Regular Saver providing five per cent AER/gross which is fixed for 12 months.

Britons can save up to £200 a month paid by standing order from a Santander current account.

Alternatively their Easy Access Saver offers 1.70 per cent AER/gross (variable) for 12 months.

For savers wanting to bank elsewhere, the top easy-access cash ISAs pay 5.17 per cent – so even if someone doesn’t need the tax benefits of an ISA, they may want to opt for an ISA in order to get higher rates, according to moneysavingexpert.com.

Alternatively Monument Bank pays 5.01 percent, but is for those looking to save a minimum of £25,000. The account offers unlimited withdrawals.

Those who have less to save can opt for Principality Building Society. Their Online Bonus Double Access account pays five per cent, with a minimum deposit of £1.

However, it should be noted that it does have a 12-month 0.15 per cent bonus as part of the rate, which means it will drop after this period.

Those who can afford to lock their money away for a period of time can get up to 5.25 per cent on Atom Bank’s fixed rate saver.
