Mettle is the first standalone business banking app to be offered by one of the UK’s high street banks, in this case NatWest. Following a pilot phase, Mettle saw its full launch in November 2019, and it’s looking to rival the mobile app-based business accounts already offered by challenger banks.

What is Mettle?

Mettle is a standalone business banking app offered by (but separate to) its parent company, high street bank NatWest. It has been featured in our best business bank accounts guide, with a standout mention for accounting software integrations.

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 lets business customers apply for an account in minutes, forecast business performance and create invoices. 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 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. Mettle can connect to accounting packages like FreeAgent, 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.
  • 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.
  • Apple Pay and Google Pay. You can add your Mettle card to these mobile payment wallets.

How to open a Mettle account

These are the steps to open a Mettle account:

  1. Download the Mettle app from the App Store or Google Play Store.
  2. Complete the application – Mettle will ask questions about you and your business.
  3. Verify your ID and provide a business document.
  4. Once approved, you’ll get an account number and sort code to get started.

Mettle customer reviews

Mettle has an average rating of 4.8 out of 5 from around 4,000 reviews on the App Store, and 4.8 out of 5 from just over 1,000 ratings on the Google Play Store (October 2021).

On Trustpilot, Mettle has nearly 900 customer reviews, receiving a mark of 4.6 out of 5, and a rating of Excellent. Many users praised the app’s functionality and ease of use, while some other reviewers complained about issues with the account opening process.

Is Mettle safe?

Mettle is separate from NatWest and is not actually a bank, so it isn’t currently covered by the Financial Services Compensation Scheme (FSCS). The FSCS protects money you’ve deposited in a bank up to £85,000 if it goes bust – this does not apply to Mettle. However, as a provider of an e-money account, Mettle must ringfence customer funds, meaning they are still safeguarded should the company fail.

Pros and cons of Mettle

  • User-friendly app with expenses management and card control.
  • Integrates with accountancy software.

Our Mettle review verdict

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. It also 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.

Get started by visiting Mettle's website and sign up for an account. If you have read this review and decided that Mettle’s account is not for you, you can use our guide to compare other business bank accounts on the market. You can also read our review of NatWest’s own business accounts here.

“Digital-only business accounts have become more popular in the last few years – it’s not the case that you have to visit your local high street bank to open a business account any more,” says Finder’s banking publisher, Matthew Boyle. “Our comprehensive business banking section will also help you explore the business accounts which are currently available in the UK.”
