If you’ve been considering investing for your future, now might be the perfect time to start. TopCashback has launched an exclusive offer giving new customers £75 cashback when they open a Santander Stocks and Shares ISA and start investing with a minimum of £100 (or £20 per month).

How the Offer Works:

To qualify for the £75 cashback, simply:

Once your account and investment are confirmed, you’ll receive £75 cashback directly through your TopCashback account.

Important Exclusions:

To ensure you receive your cashback, keep the following in mind:

  • Cashback is only valid if you invest after clicking through from TopCashback.
  • Applications found to be fraudulent or incomplete will not be eligible.
  • Cashback will not track if you use a price comparison site or unauthorised voucher codes.
  • The offer is only available to UK residents aged 18 or over.

If your cashback doesn’t track automatically, you can submit a ‘Missing Cashback’ claim within 100 days of opening your account.

ISA Features and Fees:

Santander’s Stocks and Shares ISA allows you to invest tax-efficiently while potentially growing your money over the long term. You can also transfer existing Cash ISAs or Stocks & Shares ISAs into the Investment Hub.

Here’s what you should know:

  • Minimum investment: £100 (lump sum) or £20 per month
  • Fees: 0.35% annually on investments up to £50,000, reducing to 0.20% on £50,000–£500,000, and 0.10% on investments over £500,000
  • Account management: Fully online, with support via phone and the Santander Mobile Banking app
  • Advisory support: Access to a qualified financial adviser online, by phone, or in-branch

Please remember that stocks and shares investments carry risk. The value of your investments can go down as well as up, and you may get back less than you invested.

This £75 cashback offer from TopCashback provides an appealing incentive to start investing with Santander. With a relatively low minimum investment and flexible options for monthly contributions, it’s a practical way to take the first step toward building your investment portfolio, while enjoying a tidy cashback bonus along the way.
