If your new year’s resolution is to be better with money, you might want to start looking after the cash you already have.

Switching your bank account should be quick and hassle-free and it could make you richer in the long-run.

While some accounts – such as HSBC’s regular savings account – offer a quick cash injection for signing up, others offer a better interest rate on savings.

So if you’ve already got some money in the bank, but you want to make more interest on it, listen up!

Money Saving Expert Martin Lewis reveals the top savings accounts for all your needs:

Best easy-access savings account: The Post Office Online Saver Account

Easy-access means you can pay in and out whenever you want, but you are still getting a good rate on the money you have.

Martin recommends the The Post Office Online Saver account, which offers 1.30% gross AER variable for the first 12 months.

However, you will need to be prepared to switch accounts in a year, when this percentage drops.

Best current accounts: Nationwide Flexdirect/Tesco Bank Current Account

Nationwide Flexdirect

Rates on this accounts are higher than on the easy-access ones.

Martin suggests the Nationwide Flexdirect, which offers an interest rate of 5% AER on the first £2,500 of your cash.

The rate is fixed for one year, but drops to 1% after that – so again you’d have to look at switching after 12 months.

Tesco Bank Current Account

The Tesco Bank Current Account pays 3% AER variable on the first £3,000, but you can open two accounts, so could get 3% on up to £6,000.

Plus, Tesco Bank has guaranteed the rate will be a minimum of 3% until 1 April 2019.

If you don’t have any savings and would rather get a lump sum of cash for switching banks, check out how to get £200 for swapping to HSBC and £185 worth of vouchers by joining the M&S Bank Current Account.
