Savings Interest Rates, Switch Offers and Guides for Sidekick

Who they are

Sidekick was founded in 2022 with a mission to modernise wealth management for professionals whose financial needs have outgrown entry-level investing apps. It targets the "mass affluent" - broadly 30-45-year-olds, often working in tech or running their own businesses, who want more than a basic robo-adviser but aren't yet wealthy enough for a private bank. The app brings together savings, investing, and even borrowing in one place. It is backed by Octopus Ventures, Seedcamp and Pact, and is authorised and regulated by the Financial Conduct Authority.

Savings accounts

Sidekick offers a small but thoughtfully designed range of savings options, all starting from just £1.

The High-yield Savings account is an easy access account currently paying 4.17% AER variable. That headline rate includes a 0.56% bonus for the first 12 months, on top of a base rate of 3.61%. Access is instant. The Multi Shield Savings account pays a slightly higher 4.23% AER variable - this one comes with a 1% bonus for the first 6 months (base rate 3.23%) and withdrawals are processed the next working day. Multi Shield is designed for customers holding larger cash balances, allowing savings to be spread across multiple partner banks within a single account - which helps make better use of FSCS protection.

For those happy to lock money away, Sidekick offers fixed-term accounts paying 3.96% AER for one year and 4.01% AER for two years, with no access until maturity.

On FSCS cover, it is worth knowing that Sidekick's savings accounts are provided by UK-regulated banks, accessed via savings platform Bondsmith, each of which holds a full UK banking licence. All savings products here carry FSCS protection up to £120,000 - notably higher than the standard £85,000 limit you'd see at most high street banks.

One thing to keep in mind: the bonus rates on the easy access accounts are time-limited. Once the bonus period ends, the underlying base rate is materially lower, so it is worth diarising a review before that point arrives.

Is it right for you?

Sidekick suits savers who want a genuinely competitive easy access rate and are comfortable with an app-only experience. It is app-only, available on iOS and Android, and you sign up with an email address. The £120,000 FSCS protection level is a genuine plus for those with larger balances. That said, the boosted rates do fade after the bonus period, so it rewards those who stay engaged rather than those who set and forget.
