Have bumped this because their latest offering for their easy access instant saver is 0.69%, which includes a 0.59% bonus for the first 12 months.
One word of warning, for those that have not used Tesco Bank Instant Savers, there will be a period of about 5 days or so where you cannot withdraw from your new savings account, while Tesco Bank do some verification checks.
Do not deposit in that new account, any funds you may need in the first week, just in case.
Once the account has passed its checks, you can set up and withdraw to multiple accounts in your own name. You are not linked to just one like many other savings providers.
