Designed to meet applicable SRA and FCA requirements. For SRA-regulated solicitors firms with four or more partners, each expected to employ at least 20 staff members and generate an annual turnover exceeding £1 million. Require a nominated account to be provided as your operational external operational client account. This must be the account that any deposits to the Client Account are made from, and any withdrawals must also be made to this account. Your Cynergy Business Current Account will function as your “Office Account” and is where any interest earned on the Client Account will be paid to, in order to maintain clear segregation of client funds.
We pay 3.50% AER* (3.44% Gross) on client money deposits from £500,000 to £20,000,000.
For more information, please contact clientaccount@cynergybank.co.uk .
The gross rate is 3.44% which is tracking 0.31% (the margin) below the Bank of England Base Rate of 3.75% (subject to change). Interest is calculated daily and paid monthly on the date your account was opened. Interest will be added to your Cynergy Office Account. Rates effective after 4:00pm on 1 January 2026.

*AER stands for Annual Equivalent Rate and illustrates what the interest rate would be if interest was paid and compounded once each year.
**Gross interest is the rate of interest before the deduction of income tax. The tax treatment and the rate of interest payable depend on individual circumstances and may be subject to change in the future.
