Monzo Business passes one million customers: 1 in 6 UK businesses

Monzo Business now has over one million customers, according to coverage of the milestone in August 2026. That works out at roughly 1 in 6 UK businesses. Monzo's own annual report for the year to the end of March 2026 had already shown the business side growing quickly, with a large share of active business customers paying for a plan.

The numbers worth noting

• Over one million business customers, about 1 in 6 UK businesses.
• Nearly £7 billion set aside in Tax Pots, the feature that moves a percentage of each incoming payment into a separate pot for tax.
• Reported as the most switched-to small business account through the Current Account Switch Service.

Why it matters if you are choosing an account

Scale is not a reason on its own to pick an account, but it does answer two questions people ask. First, Monzo Business is not a niche product any more: accountants, bookkeeping software and payment providers all work with it. Second, the features most people use are the everyday ones. The Tax Pots figure suggests a lot of small businesses use their bank account to manage tax, not just to hold money.

As a limited company that has banked with Monzo Business for a few years, the Tax Pots number does not surprise us. Moving tax aside on the day the money lands is one of the habits that makes the account useful rather than just convenient.

What has not changed

Monzo Business is still for sole traders and private limited companies (limited by shares). Partnerships, LLPs and charities still cannot open one, and there are still no branches. If that rules it out for you, the alternatives page and the best business bank accounts comparison cover what to use instead. If it fits, our Monzo Business review is the place to start.
