Our verdict
Mettle is a spin-off venture from parent bank NatWest, but its app is more like a challenger's. Find out what this business bank account can offer your small businesses.
Mettle is an interesting digital play by parent company NatWest. But as it's separate from the high street bank itself, unfortunately you can't visit a NatWest branch to discuss your Mettle account. However, a digital-only business account with Mettle is free to open and use, and it has strong mobile banking features. We picked Mettle as the best app and online banking experience because its free-to-use app has some of the highest ratings from users. It comes with a useful invoicing system and the ability to integrate with accounting software like FreeAgent and Xero. Time will tell if it's successful enough to take on similar business account offerings from the likes of challenger bank rivals Starling and Monzo.

Mettle is a standalone business banking app with the backing of one of the UK’s high street banks, NatWest. Designed for sole traders and limited companies with up to 2 owners, it stands out for its lack of monthly fees, free card use abroad and accounting software integrations. It’s also been recommended as one of our best business bank accounts.
What is Mettle?
Mettle is a standalone business bank account offered by (but separate to) its parent company, high street bank NatWest. It has been featured in our best business bank accounts guide, and offers free access to accounting software FreeAgent. You can also integrate your account with Xero and QuickBooks.
This digital business account can be seen as a response to the challenger banks which have changed the face of banking in the last few years – reeling in customers by letting them open and manage app-based business bank accounts through their mobile phones, as well as offering great exchange rates for people who travel frequently. Mettle can also be accessed via the web.
Mettle lets business customers apply for an account in minutes, forecast business performance, create invoices and ringfence money for bills. All of this is possible in its mobile app, which is designed to be easy to use, as well as free to use.
How does Mettle work?
Mettle offers its users a number of features, including:
- Fast application. Mettle will let customers open a business bank account in a matter of minutes.
- Invoicing. You can create and send customised invoices on the go. The app will let you know when you’ve been paid or if you need to chase.
- Reporting. You’re able to categorise business transactions and manage your expenses. You can then export your data and share it with your accountant.
- Accounting. Accounting software FreeAgent is included for free, but you can also integrate your account with Xero and QuickBooks.
- Payments. You can schedule payments on the go and manage recurring payments directly from the app.
- Money pots. Set money aside from your main account into a “money pot”, where you can ringfence funds for future outgoings like corporation tax or VAT.
- No card fees abroad. There are no fees for using your card abroad and each transaction uses the exchange rates set by Mastercard.
- Freeze or unfreeze your card. You can lock your card in the app if you think you’ve lost it, then just unlock it if the card shows up.
There’s also the option to upgrade to Mettle+ for £4 a month. This enables you to create quotes on the go and convert them to invoices. It also gives you access to bespoke messsaging templates.
