Launched in March 2013, the Santander current account has been lauded by experts as the UK's most generous current account in terms of customer rewards, according to The Daily Mail. If you are considering making the change to the Santander account, here's what to expect in terms of risks and rewards.

The Santander account offers you cashback on purchases at a tiered system of 1-2-3. For example, the 1 stands for 1 percent cashback you receive when you use the Santander card to pay water and council tax bills. The 2 stands for 2 percent cash back on electricity and gas bills while the 3 percent stands for cashback on bills paid to mobile, home phone, broadband and on-demand television packages. You can set the account up as either a single or joint account based on your and your partner's unique needs.

The 1-2-3 comes into play in another way. You also earn interest based on the amount of money you keep in the account on a monthly basis. For example, if you keep £1,000 or more in the Santander account, you earn 1 percent interest on this amount. If you carry a balance of £2,000 or more, you will earn 2 percent interest each month. When your funds exceed £20,000, you will earn 3 percent interest for your account balance, which is the maximum interest rate you can earn with the Santander account.

If you are curious if you could benefit from the Santander account, visit the company's website at Santander.co.uk and go to the 123 Santander page. In the "What You Get" area, there is a cashback calculator. This allows you to put in your typical utility bill information to determine how much money you could get back. You also can view a list of utility providers to ensure your provider is a member of the cashback awards program.

The Fine Print

You must meet a few basic requirements to qualify for the Santander 123 card. For example, you must be older than age 18 and a permanent UK resident. In addition, you must keep a balance of at least £500 in your account and use at least two direct debits per month.

Remember that you will only earn the cashback rewards for the Santander 123 card if you have at least £1,000 in your account. If your balance drops below this amount, you will not get the cashback. To maximize the amount of interest you earn each month, follow this strategy: Keep as much money as you possibly can in your account for as many days as possible. To get the cashback rewards on your utility bills, they must be from direct debits. If you do choose to utilize direct debits, you may wish to set them all for the end of the month to maximize your interest.

You must pay a small fee to receive these benefits. The Santander card costs £2 each month to earn the cashback perks. Unlike some other cashback cards that pay once per year, the Santander card will pay cashback rewards on a monthly basis.

If the Santander 123 account does not appeal to you, but you wish to stay with the Santander company, you can choose its Everyday account, which does not offer cashback or charge a fee for holding the current account.

Making the Switch

Santander is a member of the Current Account Switch Service (CASS) that will switch your bank accounts within seven business days upon your request. The CASS system ensures you can switch your account in a hassle-free manner. If any details of the account do slip through the cracks, such as direct debits from the old account, the responsible bank must cover the costs associated with the error.
