Who it suits

  • Sole traders and limited companies that keep a business current account
  • Freelancers who want a small buffer earning something without leaving the main account
  • Anyone already paying £0 on the main account

Who should look elsewhere

  • Savings hunters after a competitive return, since Wise pays 3.29%
  • Readers wanting several pots, since only one savings pot exists
  • Anyone needing the return locked in, because the rate is variable

Fees and FX

The savings pot carries a monthly fee of £0 and the account runs on a no monthly fee basis, so nothing is charged simply for keeping it open. The minimum deposit is £10, which makes the pot easy to start with a small sum. Interest is calculated daily and paid out monthly, and money comes back to the current account by transfer. There is a single savings pot, so cash beyond the maximum balance has nowhere to sit.

Frequently asked questions

What interest does the Mettle savings pot pay?+

The pot pays a variable rate of 0.95%, so the figure can move rather than staying locked in. Interest is calculated every day and paid out monthly into the linked account. The site median across listed savings is 3%, and Wise pays 3.29%.

Is my money protected if Mettle fails?+

Deposits are covered by FSCS up to GBP 85,000, so eligible savings are reimbursed by the FSCS if the provider cannot pay. The account comes from National Westminster Bank plc, which is regulated in the UK by the Financial Conduct Authority and the Prudential Regulation Authority under 121878.

How much do I need to open the savings pot?+

The minimum deposit is £10, so the pot can be started with a modest sum. The monthly fee on the account is £0. The pot is an easy access account, which suits readers who may need the money without giving notice.

Can I have more than one savings pot?+

No. Only a single savings pot is offered, so money beyond that one balance has no home with the provider. Readers who want several separate pots should look at an alternative that offers more. Savings can be topped up as long as the total stays within the maximum balance.

How do I get money out of the pot?+

Money comes back by transfer into the main current account rather than as a cash withdrawal. Because the pot is easy access, there is no notice period to serve before the balance is moved. Interest keeps being calculated daily until the balance is drawn down.

What support can I reach on Mettle?+

Support runs through chat, email and phone, covering chat, email, phone and a help centre, so questions can be raised by phone as well as in writing. The account is a UK service from National Westminster Bank plc, which means support is UK based.

Is the interest rate fixed or variable?+

The rate is variable, so the provider can change it and there is no fixed term locking the figure in. The current rate is 0.95%. Readers who want certainty for a set period will find more choice among fixed rate savings elsewhere.
