The big appeal of Mettle is that is completely free to use. There is no opening fee, no monthly charge, and no penalties attached to microtransactions. It even comes bundled with FreeAgent bookkeeping software, potentially saving up to £150 per year.

However, Mettle accounts cannot accept cash or cheque payments, and can only be used within the UK as no IBAN number is included, while account limits are also lower than some rivals.

If this all sounds too good to be true, there are a couple of warnings to sound about banking with Mettle. This account is not compatible with overseas transactions. Mettle accounts do not provide an IBAN number, so you cannot send or receive money in different currencies.

Mettle also has some quite strict limits on how much you can hold in your account. Sole traders can hold a maximum balance of £50,000, and companies £100,000. This may make Mettle unsuitable for a business that trades in large sums in and out. This app is best used by sole traders and SME owners at the very onset of their business journey.

Mettle business eligibility criteria

Mettle app user interface

Any SME or sole trader based in the UK can apply for a Mettle account. If you are representing a business, your company cannot have more than two owners, and only one of these will be granted access to the Mettle account.

Mettle typically makes a decision about whether to approve an account within 48 hours, but you will need to answer some questions about your business model and operating practices. You may find that Mettle comes back to you and asks for more information on multiple occasions before a final decison is made.

Mettle business finance alternatives

If Mettle is not for you, you will find no shortage of app-based challenger bank rivals. Many of these will offer more features than Mettle, such as the ability to take out a business overdraft or apply for a business credit card or unsecured loan, but will not match the cost-effectiveness of Mettle. Finding a business bank that allows you to handle your finances without any kind of charges or fees is a rarity to cherish.

Mettle additional considerations

Mettle was the winner of the Business Banking category in the Finder Banking Customer Satisfaction Awards 2023, beating out competition from a range of big hitters and major high street names.


Is Mettle a proper bank?

What fees does Mettle charge for its business accounts?

Mettle charges no setup or monthly fees for business accounts. Instead, it makes money from the interchange fees charged on card payments and transfers, as well as other service fees that come with banking services such as foreign currency transfers and international payments.
