It’s an online account from Hampshire Trust Bank (HTB) and pays 5.01% AER (5% gross) on a minimum deposit of £1, data from Savings Champion revealed.

It comes as savings rates on one-year accounts fell back slightly after hitting 5% for the first time since 2009 earlier this month.

The last time an account in the two-, three-, four-, or five-year fixed tables paid 5% or more was November 2022.

The best buy account in the one-year savings market is currently from Allica Bank with its 12 Month Fixed-Term Personal Savings Account (Issue 40), paying 5% AER/gross on a minimum investment of £10,000.

Meanwhile, the fixed-rate ISA market is also fiercely competitive with just 0.01% separating the top accounts.

Successive base rate rises from the Bank of England (BoE) have resulted in rate hikes by many savings providers. It now stands at 4.5% after 12 consecutive increases.

Here we look at the top-paying ISA accounts available this week, as listed by Moneyfacts.

The best easy access cash ISAs

Top of the savings charts this week is the Limited Access e-ISA and the Limited Access ISA from Yorkshire Building Society paying 3.60%. The accounts can be opened with £1 and interest is paid yearly. It allows withdrawals on one day per year based on the anniversary of account opening, plus closure at any time.

The only difference between the two are how they can be opened and managed, with the e-ISA only available via online channels, while the alternative ISA can be opened and managed in branch and by post.

The next best accounts are as follows:

1. Chorley Building Society’s Easy Access Cash ISA (3 Withdrawals): Paying 3.55%, this account can be opened with £1 online, in branch or by post. It allows three withdrawals per year with any extra withdrawals resulting in lower interest on the remaining cash.
2. Paragon Bank’s Triple Access Cash ISA – Issue 13: Paying 3.51% this account can be opened and managed online with a £1 deposit. Further withdrawals will result in a lower rate of interest.
3. Cynergy Bank’s Online ISA (Issue 36): This ISA pays 3.50%, can be opened with £1, and interest is paid yearly. It’s an online account and you’ll need the Cynergy Bank Authenticator App or Digipass to open and manage your money.
4. Shawbrook Bank’s Easy Access Cash ISA – Issue 24: Paying 3.45% this online account can be opened with £1,000. It can also be managed on the phone and interest can be paid monthly or on the anniversary of opening the account.

This week’s best fixed-rate cash ISAs
