THOUSANDS of customers have hours left to make a key move or miss out on extra cash.
Sainsbury’s Bank is set to end the option for cash ISA holders to transfer their savings to a new provider ahead of its takeover by NatWest.

Customers have until 11.59pm tonight to initiate an ISA transfer to an alternative provider, potentially securing a more favourable deal and avoiding any exit fees.
Those who fail to act before the deadline will see their savings automatically transferred to NatWest on May 1, pending court approval.
This move follows the bank’s recent decision to stop accepting applications for savings accounts from both new and existing customers.
Sainsbury’s Bank is preparing to transfer its personal loans, credit cards, and savings accounts to NatWest under an agreement subject to court approval on April 15.
All insurance and travel money services will continue to be available as they are not included in the proposed transfer.
However, if the transfer is approved, all Sainsbury’s credit cards, loans, and savings accounts will be transferred to NatWest ownership from May 1.
Existing customers with a savings account or cash ISA at Sainsbury’s Bank will not be immediately impacted by the changes.
You will still be able to access your account as usual, check balances and account details, and transfer money (unless your funds are in a fixed-term account) by logging into Sainsbury’s online banking.
Your username, password and security details will also remain the same.
However, Sainsbury’s Bank has stated that once your accounts are transferred to NatWest’s systems – expected to happen towards the end of 2025 – you will no longer be able to access them via Sainsbury’s Bank’s online banking.

Further details on how to do this will be provided closer to the time.
If you currently hold a Cash ISA with Sainsbury’s Bank, it could be worth checking if a more competitive interest rate is available elsewhere and consider transferring your savings.
While those with a regular savings account can switch providers at any time, ISA holders must initiate a transfer with their new provider to ensure their funds remain within the tax-free ISA wrapper.
What will happen to my cash ISA if I don’t act?
NatWest will become the ISA Manager for all Sainsbury’s Bank ISAs from May 1, 2025.
Other than the change in ISA Manager, your ISA will continue to function as normal and you will continue to receive the same amount of interest as before.
If you hold ISAs with both Sainsbury’s Bank and NatWest/Ulster Bank Northern Ireland, the accounts will remain separate, and you can continue contributing to them within the £20,000 annual ISA allowance.
To preserve the tax-free status of your ISA, the change in ISA Manager will be handled via an HMRC-managed bulk transfer process.
Customers will receive a separate notification regarding this process at least 30 days before the transfer.
[boxout headline=”What is an ISA?” intro=”SAVERS can put away £20,000 a year into individual savings accounts, also known as ISAs, and any income or gains you make from them are shielded from tax.”]This is different to regular savings accounts, where you are taxed on income earned from interest once you breach a certain limit – known as the personal savings allowance (PSA).
Basic rate taxpayers have a PSA of £1,000 while higher rate taxpayers get £500.
Anyone who is an additional rate taxpayer (taxed at 45%) has to pay tax on any interest they earn and gets no allowance at all.
You can split your £20,000 ISA limit between multiple ISAs, whether that’s a cash or stocks and shares ISA (we explain the different types below).
You don’t have to save the full £20,000 a year either.
There are several different types of accounts:
- Cash ISAs: A savings account where interest is earned tax-free. Suitable for risk-averse savers.
- Stocks and Shares ISAs: Invest in shares, bonds, and funds with potential for higher returns, but also higher risk. Gains are tax-free.
- Lifetime ISAs: Save up to £4,000 a year towards your first home or retirement, with a 25% government bonus on contributions.
- Junior ISAs: Tax-free savings accounts for children under 18. Available as cash or stocks and shares ISAs, with a yearly contribution limit.
- Innovative Finance ISAs (IFISAs): Invest in peer-to-peer lending with tax-free interest. Higher risk but potential for higher returns.
What if I’ve found a better cash ISA rate elsewhere?
Customers who do not wish to transfer their ISA to NatWest can opt out of the bulk transfer.
To do this, they must either close their ISA (losing its tax-free status) or request a transfer to another ISA Manager.
Requests must be submitted by March 20, 2025 to allow sufficient time for processing ahead of the May 1, 2025 transfer.
If opting out, any notice periods, penalties, fees, or charges will be waived between February 27, 2025 and July 1, 2025.
After the transfer to NatWest, customers will still have the option to move their ISA to another provider at any time, subject to NatWest’s terms and conditions.
However, if you’ve found a better cash ISA rate elsewhere now, it could be worth switching today.
Transferring your cash ISA to a new provider is generally straightforward.
Your new ISA provider will handle the entire process.
Check with both your current and new providers about any potential transfer fees or penalties.
Once you’ve chosen a new ISA, apply for it with the new provider.
Cash ISA transfers usually take up to 15 working days.
However, it can sometimes take longer, so it’s best to allow up to 30 days.

As the name suggests, these accounts typically allow unlimited withdrawals, offering convenience and flexibility.
However, it’s worth noting that interest rates are variable and can change at any time.
The best easy access cash ISA currently pays 5.03% from Chip and you can start saving with just £1.
Notice accounts offer slightly lower interest rates than the easy-access account.
For those willing to trade a small degree of flexibility, notice accounts may be worth considering.
While they often offer slightly lower interest rates than easy access ISAs, they still allow access to your funds, and their interest rates are usually fixed for a short period, providing greater stability.
Tipton & Coseley’s 60 day notice account offers savers 4.5% back with a minimum £1,000 deposit, for example.
However, if you’re looking to grow your savings and don’t need regular access to your funds, a fixed-term cash ISA could be a better option.
The best fixed rate currently offered is Castle Trust Bank one-year fixed rate cash ISA, which pays 4.49%, requiring a minimum investment of £1,000.
[boxout headline=”How do I find the best savings rates?” intro=”WITH your current savings rates in mind, don’t waste time looking at individual banking sites to compare rates – it’ll take you an eternity.”]Research price comparison websites such as MoneyFactsCompare.co.uk and MoneySupermarket.
These will help you save you time and show you the best rates available.
They also let you tailor your searches to an account type that suits you.
As a benchmark, you’ll want to consider any account that currently pays more interest than the current level of inflation – 2%.
It’s always wise to have some money stashed inside an easy-access savings account to ensure you have quick access to cash to deal with any emergencies like a boiler repair, for example.
If you’re saving for a long-term goal, then consider locking some of your savings inside a fixed bond, as these usually come with the highest savings rates.
