When you open a Fixed Rate Cash ISA, you can choose to add funds into the account as an initial deposit. The minimum opening deposit is £500, but you pay in anything that is remaining of your ISA allowance for this tax year, so up to £20,000.
Unlike other Fixed Rate Cash ISAs, with a Tembo Fixed Rate Cash ISA, you can make further one-off contributions into the account after you’ve opened it. This allows you to keep locking your money away for your long-term goals as you have more funds available.
The minimum contribution by one-off contribution is £500 and must come from a UK current account where you are named as the sole account holder. New funds added to your Fixed Rate Cash ISA will instantly lock in for 12 months from the date they're added, at the rate available at the time.
