Tide and Mettle by NatWest are two of the UK's most popular free business banking options, but they solve different problems. Tide is a fintech platform that scales from a genuinely free plan to a £69.99-a-month cashback account, with built-in invoicing and integrations with Sage, Xero, QuickBooks, and FreeAgent from day one. Mettle, backed by NatWest, has no paid tier at all. It stays free permanently and bundles in a full FreeAgent subscription, but skips built-in invoicing and any credit facility.
This guide compares Tide against Mettle on fees, features, eligibility and real customer feedback to help you choose the right account for your business.

What Tide Is Designed For
Tide is built for businesses that want banking, invoicing and accounting feeds in one app, with the option to pay for more as the business grows.
Key Characteristics of Tide
Free business current account with a paid upgrade path (Smart, Pro, Max)
Built-in invoice creation and automatic payment matching
A direct live bank feed to Sage, alongside Open Banking connections to Xero, QuickBooks and FreeAgent, all available on the free plan
A linked Tide Instant Saver account, with rates rising from 2.00% AER on Free up to 3.75% AER on Max
Company formation available from £14.99 standalone, or £1 with a Company Secretary subscription
Available to sole traders, freelancers and UK limited company directors
Trade-Offs to Consider
Five free transfers a month on the free plan, then 20p per transfer in or out
No overdraft facility on any plan
Invoicing is capped at 3 a month on Free, Smart and Pro; only Max makes it unlimited
Partnerships and LLPs are not eligible to open an account
Not a bank in its own right; the licence sits with ClearBank
Tide typically appeals to invoicing-led businesses whose accountant works in Sage, or who expect to outgrow a free account as transaction volumes climb. A closer look at how it stacks up against a full banking licence is in our Tide vs Starling comparison.
What Mettle Is Designed For
Mettle focuses on stripping out cost rather than adding features, pairing free banking with a genuinely free accounting subscription.
Key Characteristics of Mettle
Completely free account with zero monthly fees and zero UK transaction fees
A full FreeAgent accounting subscription included free, conditional on at least one transaction a month from the Mettle account
Automatic transaction syncing to FreeAgent, with no separate Open Banking authorisation required
A Savings Pot paying 0.95% AER (variable) on balances from £10 up to £1m
Backed by National Westminster Bank plc, giving statutory FSCS protection rather than e-money safeguarding
Trade-Offs to Consider
No overdraft or credit facility at any level
No built-in invoicing; quote-to-invoice conversion needs the optional Mettle+ add-on at £4 a month
Only one owner can access the account, even on a two-owner limited company
Limited to sole traders and UK limited companies; LLPs and partnerships can't apply
No phone support, only in-app chat and a help centre
Mettle tends to suit consultants and small service businesses that would otherwise be paying for FreeAgent separately, particularly those with steady, predictable income rather than a need to borrow. See how it fares against a similarly free challenger in our Starling vs Mettle guide.
How They Charge
Tide Pricing
Tide's free plan costs nothing and includes five free transfers a month, then 20p each way, plus three free invoices a month. Smart costs £12.49 a month (or £99.99 a year) and adds 30 free transfers, 0% overseas card fees and a better savings rate, though it never actually beats the free plan on transfer costs alone. Pro, at £27.49 a month, is the first tier with unlimited free transfers, and Max, at £69.99 a month, adds unlimited invoicing and 0.5% cashback on eligible card spend.
A business making around 15 transfers a month pays roughly £2 on Tide's free plan, but a business making 150 or more finds Pro's flat fee works out cheaper.
Mettle Pricing
Mettle's account fee is £0, with free UK transfers in both directions regardless of volume. The only optional charge is Mettle+ at £4 a month, which adds quote creation, automatic quote-to-invoice conversion and automated client reminders. ATM withdrawals cost a flat £1 each. International transfers and cash deposit fees are not clearly published, so confirm these directly at mettle.com before relying on them.

Tide: Built-in invoice creation and tracking, with automatic payment matching, on every plan.

Regulation and Protection
Tide and Mettle sit on different regulatory footing, and this is one of the most commonly confused parts of the comparison.
Tide Platform Limited is the FCA-regulated fintech that builds the app, while new accounts are provided by ClearBank, a fully licensed UK bank, which is what gives eligible deposits FSCS protection up to £120,000. Some longstanding Tide customers still hold legacy e-money accounts from before the ClearBank switch, which are safeguarded rather than FSCS-covered, so it's worth checking your sort code if you've held the account for several years.
Mettle sits under National Westminster Bank plc's own banking licence, so eligible deposits carry the same statutory FSCS protection up to £120,000. The catch is that this limit is shared across NatWest Group brands, including NatWest plc, Ulster Bank and NatWest Boxed, so a business holding balances with NatWest and Mettle needs to count the combined total, not treat each as a separate allowance.
Businesses that want a simpler, single-institution FSCS picture might prefer to keep other banking away from NatWest Group entirely. For more on how the current £120,000 threshold works, see our guide to business bank accounts with built-in accounting.
Common Misconceptions About Tide and Mettle
"Mettle is basically a NatWest business account." It isn't. Mettle is a standalone, app-only brand within NatWest Group. You get none of NatWest's branch network, staff or product range through a Mettle account, and the two products aren't interchangeable day to day.
"Tide is a bank." Tide itself doesn't hold a banking licence. It's the FCA-regulated platform and app; the licensed bank behind new accounts is ClearBank. That distinction is exactly what determines whether your money is FSCS-protected.
"Both providers offer free invoicing." Tide includes invoicing on every plan, but only three a month below the Max tier. Mettle's standard app has no built-in invoice creation at all; quote-to-invoice conversion only arrives with the paid Mettle+ add-on.
"Mettle's FSCS cover is separate from NatWest's." It isn't additional protection. The £120,000 limit applies across your combined balances with NatWest Group brands, not £120,000 for each one you hold.
"Free means no fees." On Tide's free plan, "free" refers to the monthly subscription. Transfers past the first five each month cost 20p, and ATM withdrawals and cash deposits carry separate charges.
What Real Customers Say About Tide and Mettle
Tide holds a Trustpilot rating of around 4.4 out of 5 from more than 36,800 reviews as of August 2026. The recurring praise is for fast account opening and an invoicing flow that works without friction, while the main complaints cluster around support response times and account restrictions during compliance checks, a pattern common across app-based business accounts rather than unique to Tide.
Mettle sits at around 4.5 out of 5 from over 6,400 Trustpilot reviews as of July 2026, an "Excellent" rating. Positive reviews focus consistently on account simplicity and the value of the bundled FreeAgent subscription, particularly among freelancers who'd otherwise pay for it separately. The main recurring complaint is around application delays, with some customers reporting waits of several days for account approval during identity checks.
Reddit sentiment broadly echoes the Trustpilot pattern: satisfaction with day-to-day use, occasional frustration with account reviews or delayed approvals.

FAQs About Tide and Mettle
Is Tide or Mettle better for a limited company?
Both accept UK limited companies, though Mettle caps this at companies with up to two owners and only one person can access the account, while Tide has no owner limit and supports multiple team members with expense cards on paid plans. A growing company with several directors is likely better served by Tide.
Can I get an overdraft with Mettle or Tide?
No, Tide offers no overdraft on any plan, and Mettle doesn't offer one either. Businesses that need short-term credit access should look elsewhere.
Are Tide or Mettle Accounts FSCS protected?
Both are. Tide's new accounts are FSCS-protected to £120,000 via ClearBank, and Mettle's are protected to £120,000 via National Westminster Bank plc, though that limit is shared with other NatWest Group accounts you hold.
Does Mettle or Tide offer free invoicing?
Tide includes three free invoices a month on Free, Smart and Pro, and unlimited invoicing on Max. Mettle has no built-in invoicing on its free account; quote-to-invoice conversion requires the £4/month Mettle+ add-on.
Can sole traders use Tide or Mettle bank accounts?
Yes, both accept UK sole traders as a core eligible business type.
Which has better accounting software integration?
Tide connects directly to Sage, Xero, QuickBooks and FreeAgent. Mettle bundles a full FreeAgent subscription free, but hasn't confirmed direct connections to other accounting platforms. Choose based on which software your accountant actually uses.
Are Mettle business bank accounts really free?
Yes, for UK banking: no monthly fee and no transfer charges. The exceptions are a £1 ATM withdrawal fee and the optional £4/month Mettle+ upgrade if you want invoicing features.
