Cashback exclusions and terms

Exclusions
  • If your application for the savings account is denied.
  • You will not be eligible for cashback if the account application is in any way fraudulent, e.g. has been obtained with stolen or fabricated personal details.
  • You will not be eligible for cashback if you get a quote via Top Cashback but then purchase using a price comparison site.
  • Use of a promotional/voucher code not posted and approved by TopCashback.
Terms
  • Cashback is calculated for the item(s) price only, not including VAT, delivery or other fees.
  • You’re a UK resident aged 18 or over
  • You open the account with £500 or more.
  • After 12 months, we’ll transfer your account to an ISA Saver. Before the term ends, we'll contact you with your new interest rate.
  • You can only open this account in your sole name – joint ISAs aren’t allowed.
  • You can only pay into one Santander cash ISA each tax year, but other providers may let you pay into more than one ISA of the same type within the same tax year. A tax year runs from 6 April in one year to 5 April the next.
  • The ISA allowance for the 2025/26 tax year is £20,000. Deposits can be made up to and including 5 April 2026.
  • Minimum balance: £500. You can open the account with a zero balance if you are transferring in existing ISAs with a balance of at least £500.
  • Maximum balance: £2 million – but you can only pay in up to your ISA allowance each tax year.
  • You can pay money in electronically or you can ask us to do a transfer for you from an existing ISA with another provider.
  • This product doesn’t accept additional permitted subscriptions.
  • This ISA isn’t flexible. That means if you take money out, it will lose its tax-free status. If it’s repaid into an ISA, it’ll count towards your ISA allowance for the current tax year.
  • Cashback is confirmed within 90 days of your savings account application being accepted.
  • Make sure you have third party cookie tracking enabled and you allow the confirmation page to fully load before closing the window. We highly recommend you clear your cookies before proceeding through this link.
  • Cashback rates are subject to change and may increase or decrease at any time.
  • Cashback is not issued by the merchant. If you have any queries regarding cashback or payments, please contact Top Cashback directly and not the merchant.
  • Please take note of the 'OLA' reference number provided to you by Santander when applying for this product. Top Cashback will need this reference number to discuss any ‘Missing Cashback’ claims.
  • Should your cashback fail to track automatically, please submit a 'Missing Cashback' claim within 100 days of your order.
