Pros and cons

Pros

  • The access terms allow unlimited withdrawals without notice, with no penalty fees.
  • Support covers email, phone and chat, so help is not limited to the app.
  • Authorised in the UK by the Prudential Regulation Authority under 575105.
  • The account opens from a £1 minimum deposit.

Cons

  • The service is digital only, so there is no branch counter to visit in person.
  • The rate is variable, so the 4.15% figure can move during the life of the account.
  • The headline rate ranks 136 of 473 on the site, so higher figures sit elsewhere.

Frequently asked questions

What does the Cynergy Bank easy-access account cost to keep?+

There is no monthly charge: the account runs under no monthly fee and the minimum deposit is £1. Monthly fees across the site reach €449, so a fee-free model matters for anyone keeping spare cash.

What rate does Cynergy Bank pay on easy-access savings?+

The easy-access account pays a variable rate of 4.15%, above the site median of 3%. Because the rate is variable it can move, and the account is an easy access one rather than a fixed-term product.

How is money in the account protected?+

Deposit protection is FSCS up to GBP 85,000, listed against Cynergy Bank plc. The bank is authorised in the UK by the Prudential Regulation Authority, so the protection limit is the reference point to check against your balance.

Can I withdraw money without notice?+

The access terms set out an online-only service with unlimited withdrawals without notice and no penalty fees. With an easy access account you are not tied to a notice period or a fixed term, so short-notice cash needs sit comfortably.

What is the minimum deposit for the account?+

The minimum deposit is £1, so a small balance is enough to open the account and start earning. On minimum deposit the brand ranks 220 of 370 among the brands listed on the site.

Is Cynergy Bank only available online?+

The service is digital only, so accounts are opened and run through the website rather than a branch. Support is listed as email, phone and chat, so help is available by phone and chat as well as by email.

Who regulates Cynergy Bank?+

Cynergy Bank is authorised in the UK by the Prudential Regulation Authority under reference 575105. The legal entity is Cynergy Bank plc, registered since 2003. Most savings accounts in the site ranking are banks rather than e-money or payment institutions, so the protection limit sits with a bank.
