Sainsbury's Bank customers being transferred to NatWest: what will happen to their accounts.

According to The Sun: Thousands of Sainsbury's Bank customers will soon be without access to their accounts due to significant changes in banking services.

The bank has clarified when customers with credit cards will lose access to their accounts.

The changes occurred after Sainsbury's Bank sold its core financial services, including loans and savings accounts, to NatWest last year.

The transfer of part of the 1.8 million customers to NatWest has already begun, with mortgage holders being the first to move.

The bank has notified credit card customers that their accounts will be transferred to NatWest between October 3 and 6.

After 5:00 PM on October 3, they will not be able to use online or mobile banking.

This will result in the enforcement of new terms and conditions from October 3, 2025.

“There are no immediate changes now, and customers do not need to do anything,” said a representative of Sainsbury’s Bank. “We will continue to keep them informed throughout the transfer process.”

What has already happened at Sainsbury's Bank?

Sainsbury's Bank announced the sale of its currency exchange business, as well as car and home insurance, returning to its core product services.

The bank sold its car and home insurance business to Allianz — one of the leading insurers in the UK.

Customers will receive notifications from Allianz on the day their policies are renewed.

Those whose agreements are automatically renewed will begin transitioning to new providers from November 2025.

Sainsbury's Bank and Argos's pet and travel insurance products are currently unchanged.

The supermarket also sold its currency exchange business to Fexco Group, although 220 currency exchange machines will remain available in stores.

In March, Sainsbury’s announced that it would no longer accept new savings account applications from new or existing customers.

“Thank you for your interest, but we no longer accept applications for opening savings accounts,” the bank states on its website.

Why are Sainsbury's Bank customers moving to NatWest?

All Sainsbury's Bank customers will be transferred to NatWest systems by December.

This transition was approved by the High Court in April, paving the way for changes.

Ownership of credit cards, loans, and savings accounts officially transferred to NatWest on May 1.

However, the transition of accounts to NatWest systems will begin in October and conclude by December.

Credit card customers began receiving updates regarding changes to their accounts starting in July.

Meanwhile, customers with loans and savings accounts were informed starting in August.

Throughout September and October, NatWest will provide instructions regarding further steps, including connecting to their digital banking services.

During this time, Sainsbury's Bank will send farewell messages to customers.

From October, all customers will receive a welcome message from NatWest, and their credit cards, loans, and savings accounts will be transferred.
