From 1st May 2025 NatWest Group is taking over the core banking business of Sainsbury's Bank, specifically, personal loans, credit cards and savings accounts. This follows Sainsbury's decision to step back from banking to focus on its main supermarket business. The deal, which was originally announced back in June 2024, only received High Court approval on April 16th 2025. It means the legal transfer officially takes effect on 1st May 2025
But what does this mean for Sainsbury's Bank customers and why will it mean that some customers will want to move their savings elsewhere?
Sainsbury’s Bank customers: What changes from 1st May 2025?
From this date, the legal ownership and responsibility for transferred Sainsbury's Bank personal loan, credit card, or savings account shifts from Sainsbury's Bank plc to National Westminster Bank plc (NatWest). It means:
- A new legal provider: NatWest becomes the legal entity providing your account.
Savings Accounts & ISAs
- FSCS Protection Change: This is an important change for savers, which may lead them to seek to move some of their savings elsewhere. See the dedicated section below for more information.
- Access: Use your account as normal
- Rates: No immediate rate changes are planned, but Sainsbury's Bank has already removed rates from its website, and NatWest has only said it will keep them the same "where possible" after the later system migration. Keep an eye on your rate and compare it with the market using our savings best-buy tables.
- ISAs: NatWest is now your ISA manager (unless you opted out). It operates as normal otherwise.
Credit Cards
- Usage: Keep using your card as normal – spending, paying your bill etc.
- Terms: Credit limit, interest rates, payment dates remain the same for now. Future changes could happen after the full migration later in 2025.
- Rewards: Details on Nectar points or other benefits post-migration haven't been confirmed yet.
Personal Loans
- Repayments: Continue making payments as scheduled.
- Rates: If you have a fixed-rate loan, the interest rate is fixed for the term and will not change as long as you stick to the agreement.
What DOESN’T change immediately on 1st May 2025?
Despite the legal handover, Sainsbury’s Bank customers won’t notice any changes day-to-day yet.
- Using Your Accounts: Continue using your credit cards, accessing savings, and making loan repayments exactly as you do now
- Account Details: Your account number and sort code (where relevant) stay the same for the time being.
- Terms & Conditions: Your existing T&Cs for loans, credit cards, and savings accounts remain unchanged at this point
- Contact Point: Sainsbury's Bank remains your point of contact for service, questions, and complaints until further notice.
FSCS savings protection change: Check your savings are still fully covered?
The most critical immediate impact starting 1st May 2025, especially if you have savings with both Sainsbury's Bank and NatWest.
- What is FSCS? The Financial Services Compensation Scheme protects your savings up to £120,000 per person, per UK-authorised banking institution if the bank fails.
- How it Worked Before 1st May: Sainsbury's Bank and NatWest had separate banking licences, meaning you had the protection for each if you banked with both.
- How it Works FROM 1st May: Because NatWest is now the legal owner of the transferred Sainsbury's Bank accounts, they share the same banking licence for FSCS purposes. This means the £120,000 limit now applies collectively across all eligible deposits you hold with:
-
- NatWest
- Sainsbury's Bank (your transferred accounts)
- Ulster Bank Northern Ireland (also part of NatWest Group).
ACTION REQUIRED: If your total savings across these three brands combined now exceed £120,000, then the amount over the limit is not protected by FSCS under the standard rules. You should consider moving the excess funds to a different bank or building society (one with a separate FSCS licence) to ensure all your money is protected. (Note: Other NatWest Group brands like RBS and Coutts currently have separate licences).
You can view our savings best-buy tables to find the best savings accounts available in the UK and then use the FSCS checker tool to check which banks and building societies share a banking licence.
Which Sainsbury’s Bank products are NOT moving to NatWest?
It's worth remembering that this deal only covers personal loans, credit cards, and savings/deposits. The following stay separate and are not part of the transfer to NatWest:
- Sainsbury's Bank Insurance
- Sainsbury's Bank Travel Money
- Sainsbury's Bank ATMs
- Argos Financial Services (including the Argos Store Card)
Sainsbury's will update on plans for Argos Financial Services separately.
What happens after 1st May (Later in 2025)? The Full Migration
While 1st May is the legal transfer date, the operational move of your accounts onto NatWest's systems is planned for towards the end of 2025.
- System Move: Your account data will be migrated to NatWest's platform.
- Online/Mobile Banking: You will eventually stop using the Sainsbury's Bank website/app and will need to register for and use NatWest's online banking and mobile app.
- Communication: Don't worry, you don't need to do anything yet. NatWest and/or Sainsbury's Bank will contact you directly before this happens with detailed instructions on what to expect and how to get set up on NatWest's services.
Who do I contact if I have questions?
For now, continue to contact Sainsbury's Bank for any questions, service requests, or complaints regarding your transferred personal loan, credit card, or savings account. They remain responsible for servicing your account until the full migration later in 2025.
Sainsbury's Bank also has a dedicated webpage with information about the transfer to NatWest.
