With a much higher rate than the big banks, you’ll be growing your savings faster.

Because you won’t pay tax up to your £20,000 each year, you’ll earn interest on the interest you've earned.

Protected
 by FSCS

Click here to learn more about how your money is protected.


The FSCS protects up to £85,000 that you have saved, per bank, building society or credit union (or up to £170,000 for joint accounts), subject to eligibility.


If you've got existing savings with Citibank or Lloyds, the FSCS protects up to £85,000 per person, per financial institution, so you may want to check whether any additional savings with them would mean you exceed the protection limit.
