Can joint account or additional account holders get Boosts? 

Yes, as long as you have a Santander credit card or debit card (in your name and issued in the UK) and you are registered for Online or Mobile Banking. If you are an additional credit card holder only, you won’t be eligible for Boosts. Other eligibility criteria also apply.

Why do you need to take my Santander card details for Boosts?

Your Santander card details are needed for security reasons, as it’ll help us confirm your identity. Capillary Technologies Europe Limited who administer this service on our behalf will use these details to pay your cashback correctly. Once registered, you need to keep your card details up to date.

You can register one Santander card at a time and it’s easy to do.

Changes to our Santander Boosts service

Important information

We’re making some exciting changes to our Santander Boosts service.

Soon we'll be launching Card Linked Offers on Santander Boosts. After 20 November 2025 you’ll start to see new offers on the Santander Boosts platform. Once you’ve activated a Card Linked Offer, you’ll be able to earn cashback on purchases. 
All you need to do is use any of your Santander debit or credit cards. To make sure we can provide these offers and track your cashback, we’ll share your Santander debit and credit card transactional data with the Santander Boosts administrator, Capillary Technologies Europe Limited. 

What do you need to know 

We’ve updated the Santander Boosts terms and conditions to reflect the changes we’re making. 

• At clause 2.1 (How the service works) to explain that we’ll share your Santander debit and credit card transactional data with Capillary Technologies Europe Limited. They’ll use this data to track eligible cashback purchases you’ve made on the service to make cashback payments to you. They’ll also use this information to show you more relevant and personalised offers.
• At clause 3 (Registered Card) because you’ll be able to make purchases by using any of your Santander debit or credit cards.
• At clause 4.10 (Card Linked Offers) to explain that you must activate a Card Linked Offer on the Santander Boosts platform before you use your card for Card Linked Offers. 

We’re letting you know now, so you have time to understand the changes before they take effect. 
These changes will happen automatically and there’s nothing for you to do. You can keep using your Santander Boosts account as normal.

What are your options? 

1. If you’re not happy with these changes, you can close your Santander Boosts account before they come into effect. If you do, we’ll pay any pending or confirmed cashback to you as per your Santander Boosts terms and conditions (clause 6.4). You’ll no longer be able to earn cashback or access any other offers.
2. You can continue to use your Santander Boosts account as normal. If you choose to close your Santander Boosts account after the changes come into effect, you’ll lose any pending or confirmed cashback as per the Santander Boosts terms and conditions (clause 5.8).

To close your Santander Boosts account, simply go to the ‘My settings’ section in your profile and click ‘Opt out of Boosts’.

You can re-register for Santander Boosts at any point in future, but details related to your previous Santander Boosts account will be lost.

What to do next

If you have any questions you can chat with us through Online and Mobile Banking.
