Mettle UK - quick overview

Mettle is a free business bank account built by NatWest to serve UK-based sole proprietors and small limited liability companies with no more than two owners¹.

NatWest wanted to do more to help underserved SMEs², so they built Mettle, a neobank, to provide a free business bank account for domestic UK SMEs and to meet up with changing customer expectations of digital and mobile banking services.

Mettle offers a free business bank account, conditional access to free invoicing and bookkeeping services, Financial Services Compensation Scheme (FSCS) coverage, automated reconciliation and money pots for savings.

Mettle key features

Mettle has a lot of helpful and practical solutions, including its Mettle pots, customizable invoice templates, a tax calculator (supported by FreeAgent) and a Free FreeAgent account.

Mettle Pots

Mettle business bank accounts let you create Savings and Regular Pots to store up money in different sub-accounts.

  • Savings Pot: Mettle’s Savings Pots lets you earn interest on savings at 1.06% Annual Equivalent Rate (AER) / 1.05% Gross per annum (variable)¹¹ (correct as of 29-07-25). The interest rate fluctuates depending on shifts in the savings market. This interest is calculated daily and paid monthly on funds as low as £10 but is only available for Savings Pots¹¹. Mettle allows users to save up to £1 million in their savings pots, but they can have only one savings pot.¹¹

  • Regular Pot: You can set aside up to £100,000 in a Mettle Regular Pot.¹² Though these attract no interest, you can save for important lump sum financial obligations like taxes, insurance and payroll with up to 30 different Regular Pots.¹² You can automatically transfer a set percentage of your earnings at scheduled times till it reaches your savings goals.

Customizable invoice templates:

Mettle lets you track the status of your receivables, match incoming payments to invoices, reconcile several payments to a single invoice and multiple payments to one invoice.¹³ This saves you the time and effort you'd have spent on manual cash application and reconciliation.

Tax payment solutions:

The UK Government's MTD for Income Tax Self Assessment requires self-employed individuals and landlords with business or property above £50,000 to maintain digital records and send quarterly reports to the HMRC starting from April 2026. This threshold will be lowered to £30,000 by April 2027.¹⁴ Mettle’s Tax-friendly features help you stay compliant by enabling you to:

  • Access FreeAgent, an MTD compliant accounting app¹⁵

  • Save images of receipts within the app.¹⁶

  • Keep tabs on tax timelines¹⁷

  • Maintain a real-time record of how much tax you owe the government using FreeAgent¹⁷

  • Automatically group revenue and expenses and predict your tax position¹⁶

  • Automate tax preparation by scheduling and saving towards paying taxes¹⁶

    Note - to get accurate tax calculation and tax timelines, you'll have to link your Mettle account to your FreeAgent account.¹⁶

Conditional Free FreeAgent Access:

If you carry out a minimum of one transaction monthly, you can enjoy FreeAgent without cost (saving £150 annually). However, you may incur FreeAgent’s fees if you close your Mettle account or do not transact with it monthly.¹⁸

Corporate debit card:

Mettle offers a debit card that supports cash withdrawals across most countries worldwide with a £10,000 daily payment limit.⁷ You can get your debit card within 1 week of opening a Mettle account.¹⁹

FSCS protection

Up to £85,000 (eligible deposits) are protected by the Financial Services Compensation Scheme.¹

Mettle+:

Mettle offers an optional paid add-on called Mettle+ that enables Mettle users to create quotes and convert them to invoices with tailored messaging templates at £4 monthly.²⁰

Mettle account limits

Though Mettle ticks a lot of boxes for small UK-based businesses, it has some obvious limitations.

  • 2.1 million account balance threshold: You can hold up to £2.1 million in total in your Mettle main balance and savings pot. This includes:
    • 1 million in your Mettle main account balance
    • An additional £1 million in your Savings Pot
    • £100,000 across all your Regular Pots.⁷
  • Large enterprises and partnerships are ineligible: Mettle business accounts are only available to sole proprietors and small companies with not more than two directors.¹ It also lacks multi-user access, meaning that only one director from a small company can own and control a Mettle business bank account. Additionally, it doesn't support partnerships where multiple sole proprietors do business together.
  • No global or multi-currency transactions: Mettle does support international. So it's unsuitable for businesses with a global customer base.
  • No lending or credit cards: Mettle doesn't offer lending²², credit cards²³ or overderafts²⁴. You can only spend what you earn.

It's best suited for sole traders who don't need credit, are heavy cash-based transactions, have large account balances (£2,100,000+) or have an international client base. Mettle isn't suitable for Trusts, publicly traded companies²¹, international companies, cash-heavy businesses, and enterprises.

Mettle fees

Mettle business accounts are free to set up and have no transaction or monthly fees. This means better margins for your small business and improved profits. They do have some paid add-ons like Mettle+, which automatically converts quotes to invoices for £4 monthly.²⁰

Mettle is best for domestic UK businesses since they don’t offer international payments.
