Cynergy Bank was established in December 2018 following the acquisition of Bank of Cyprus UK, which had been operating in the United Kingdom since 1955. It describes itself as a specialist bank serving the needs of business owners, entrepreneurs and family businesses, though it also actively competes for retail savers. The bank positions itself as a "human-digital" provider - tailored solutions delivered by people and enabled by technology. It is rated "Excellent" on Trustpilot from over 5,000 reviews. One thing worth noting on FSCS cover: eligible deposits are protected up to £120,000 by the Financial Services Compensation Scheme - that is higher than the standard £85,000 limit you see at most banks, which reflects Cynergy's status as a separate, independently licensed institution.
Cynergy keeps its savings range simple and online-focused. The Online Easy Access Account pays 4.23% AER, but it is worth reading the small print: that rate includes a 2% bonus for the first 12 months on top of a 2.23% base rate, so expect a meaningful drop once the bonus period ends - set a calendar reminder at around 11 months. The minimum deposit is just £1, so it is easy to get started.
If you are happy to lock your money away, Cynergy's Fixed Rate Bonds span a wide range of terms - 6 months, 1 year, 15 months, 18 months, 2 years, 3 years, 4 years and 5 years - all currently paying 4.35% AER with a £1,000 minimum. There is no access until maturity, so only fix what you genuinely will not need. For ISA savers, the Online ISA pays 4.15% AER on a variable, easy-access basis with no minimum beyond £1.
All accounts carry FSCS protection up to £120,000.
Cynergy suits savers who want a straightforward, online-managed account and appreciate a slightly higher FSCS protection limit. The easy-access rate is competitive right now, but the 2% bonus cliff means it rewards those who stay organised and switch or renegotiate when the time comes. The fixed-rate range is broad if you want to ladder your savings across different terms. There are no current-account switch offers in place at the moment.
