Cash ISAs
Santander savings accounts
Santander offers a broad range of savings accounts with interest rates up to 6%.
No prizes for guessing which Spanish city was the birthplace of the bank Santander. Since its entry into the UK market in 2004, Banco Santander has acquired 3 former British building societies and formed the retail and commercial giant that stands today. Santander's top savings rate of 5% is available on its regular savings account.

How we picked these
What is Santander's best savings account with the highest interest rate?
The best savings account depends on what you want from your savings. If you're after fast access to your money, then an easy-access account should suit you. However, if you're happy to lock your money away for a time to access a higher rate, then a fixed-rate bond is a good option.
Finally, if you're looking to maximise your returns and shield them from income tax, consider an ISA. Below, we've listed the different types of accounts Santander offers, plus the highest interest rate currently available.
| Savings account types include | Cash isas, fixed-rate bonds, regular savers, business |
|---|---|
| Best cash ISA rate | 4.1% |
| Best fixed-rate bond rate | 4.15% |
| Best regular saver rate | 5% |
| Best business savings account rate | 2.3% |
| Fixed bond terms | 1 year - 3 years |
| Opening options | Branch, website, mobile app, telephone |
| FSCS protection |

How do I decide which account is for me?
Firstly, you need to decide what you’re looking for in a savings account. How often are you planning to withdraw your money? How much money can you afford to save each month?
Typically fixed-rate bonds give you better interest rates. So, if you’re looking to put away a lump sum to mature, then these might be what you’re looking for.
Easy-access or instant-access accounts, on the other hand, give customers more flexibility. So if you’re saving on a budget, or you’re trying to store up cash for a big spend in a few months time (a wedding perhaps), then these might be for you.
Work out what you need before comparing the different offers available for certain types of savings accounts. Once you’ve done that, it’s useful to look at:
- Interest rates
- Fees (if there are any)
- Access to cash (if you need quick access, for instance)
Does Santander offer internet or mobile banking?
Yes. It offers both physical and digital banking services. You can open most of its savings accounts and ISAs by going online, on your mobile, or heading in branch.
However, you can’t manage all types of account online or in the app. Fixed-rate cash ISAs, for instance, are “view only” in online and mobile banking.
