Pros and cons

Pros

  • Headline rate of 4.15% on a easy access account, well above the site median at 3%.
  • Access is online only, with as many withdrawals as you like without notice and no penalty fees.
  • Deposit protection of FSCS up to GBP 85,000 sits behind eligible balances.
  • Support covers email, phone and chat for questions on saving or lending.

Cons

  • Support runs on email, phone and chat, so a branch counter is not among the ways to reach the bank.
  • The rate is variable, so the 4.15% headline can move with the base rate.
  • Private borrowing starts high, with lending of £250,000 to £2,000,000 and a wealth mortgage income or net assets test.

Frequently asked questions

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

The easy access account pays a headline rate of 4.15%, and the rate is variable rather than fixed. That sits above the site median at 3%, so it beats most accounts listed on the site, though a variable rate can move in either direction.

What fees do I pay to open and use the account?+

There are no penalty fees on the easy access account and the minimum deposit is £1. Withdrawals need no notice, so taking money out adds nothing. The figure to watch is the variable rate, which can change over the life of the account.

Can I get at my money whenever I want?+

Access is online only, with as many withdrawals as you like without notice and no penalty fees. A branch counter is not among the email, phone and chat, so you manage the balance and take money out through the website or app whenever you choose.

How much of my money is protected?+

Deposits sit under FSCS up to GBP 85,000, the deposit protection limit for each eligible person. Anything you hold beyond that ceiling is not covered by the scheme, so very large balances are better placed elsewhere.

Who regulates Cynergy Bank?+

Cynergy Bank plc is authorised and regulated by the Prudential Regulation Authority in the UK, under reference 575105. The bank is headquartered in the United Kingdom and was founded in 1955, and it lends directly rather than acting as a broker.

What can I borrow from Cynergy Bank?+

The bank lends £250,000 to £2,000,000 as a direct lender, across personal, secured and business. Mortgages cover purchase, remortgage and first time buyer, and bridging finance also sits on the books for property professionals and contractors.

Who qualifies for the mortgages?+

Consumer mortgages for purchase, remortgage and first time buyer cover first-time buyers and existing homeowners, alongside entrepreneurs, property professionals and contractors. Wealth mortgages need a set annual net income or a set level of net assets, or a guarantor who meets that same test.

How do I get help with the account?+

Support runs through email, phone and chat, so email, phone, chat and a help centre are all open to you. A phone line and a self-service help centre are both included, which covers most questions on balances, withdrawals or the lending side.
