Best fixed-rate bonds
Atom Bank pays a top rate of 1.95pc.
The Atom account, which can only be managed on its mobile app, can be opened with £50. You can download it from the App Store or Google Play.
Atom Bank also offers a market-leading two-year bond with a rate of 2.1pc although you'll need to be comfortable banking solely on an app.
The top three-year bond is offered by Vanquis Bank Savings which pays 2.25pc.
Accounts can be opened online with £1,000 and can also be managed by post or phone.
Three weeks before your account matures the bank will write to you for further instructions. If it doesn't hear anything back it will automatically pay funds into your nominated account or into its own easy-access account.
Vanquis Bank Savings also offers a best-buy four-year account with a rate of 2.42pc. Savers must have at least £1,000.
The highest five-year rate is 2.51pc and is also offered by Vanquis Bank Savings.
The minimum deposit is £1,000.
