Quick Verdict

Marcus by Goldman Sachs UK review 2026. FSCS-protected, competitive AER, Cash ISA available. Is it the best easy-access savings account for British savers?

What We Love

  • FSCS-protected under Goldman Sachs International Bank β€” direct banking licence, not a partner bank arrangement
  • Consistently competitive easy-access rate β€” top-five UK AER since 2018 with no introductory bonus period
  • Cash ISA at the same competitive rate β€” tax-free savings with ISA transfers accepted from other providers
  • No fees of any kind β€” zero monthly, inactivity, or management charges
  • No minimum balance for headline rate β€” Β£1 earns the same AER as Β£85,000 with no tiered structure

Watch Out For

  • No mobile app β€” web-only account management at marcus.co.uk, no push notifications for rate changes
  • No fixed-term products in UK β€” savers wanting to lock in rates must use a separate provider
  • No current account, investment, or additional products β€” savings only, separate accounts needed elsewhere
  • Phone wait times β€” customer service call queues can be long during peak hours
  • FSCS limit is Β£85,000 β€” larger balances need spreading across multiple institutions
