Top UK Fintech Companies 2026: Revolut, Monzo, Wise and More

A fishmonger at Kirkgate Market in Leeds takes card payments on a terminal from one fintech, banks her takings with a second, pays her Norwegian supplier through a third, and keeps her rainy-day pot in a savings app run by a fourth. Fifteen years ago every one of those jobs belonged to a high-street bank. In 2026 the UK has the deepest bench of independent fintech companies in Europe, several now profitable and fully licensed, even as fresh venture money into the sector has fallen to its lowest level in a decade.

How did we choose the leading UK fintech companies for 2026?

We selected UK fintech companies for 2026 on measurable criteria as of October 2026: customers, revenue and profit in the latest reported year, payment or lending volume, licences held, and valuation where disclosed. We grouped them by category rather than ranking them, because a challenger bank, a payment processor and a business lender earn money in very different ways.

The funding climate is the backdrop. UK fintech investment fell to £1.8 billion across 205 deals in the first half of 2026, down about two-thirds from £5.0 billion a year earlier and the lowest since KPMG began the series in 2016, according to KPMG's August 2026 release. The largest deal was a £543 million private equity investment in Ebury. Thin funding makes profits matter more, and most of this list now has them.

Which UK digital banks are largest in 2026?

By revenue and customers, Revolut is the UK's largest fintech in 2026, with £4.5 billion of 2025 revenue, £1.7 billion of pre-tax profit and 68.3 million retail customers worldwide. Monzo is second, with £1.7 billion of revenue and 15.2 million customers in the year to March 2026, and Starling is the most profitable per pound of revenue among the three.

Revolut

Revolut's 2025 revenue rose 46% to £4.5 billion and profit before tax rose 57% to £1.7 billion, with 68.3 million retail and 767,000 business customers, according to Euronews. Its last funding round valued it at $75 billion. The licence saga is over: Revolut won a restricted UK banking licence in July 2024 and the Prudential Regulation Authority let it leave mobilisation in March 2026, after about 20 months, as Tech.eu reported. It has about 13 million UK customers.

Monzo

Monzo's revenue rose 39% to £1.7 billion in the year to March 2026, with adjusted profit before tax of £172.6 million, 15.2 million customers and deposits of £25.7 billion, up 55%, per Payment Expert. It launched in Ireland in April 2026 on a Central Bank of Ireland licence and closed its US operations.

Starling Bank

Starling is the exception to the growth story. Revenue fell to £887 million in the year to March 2026 and pre-tax profit dipped 3% to £217 million as interest income dropped with rates, while accounts rose to 6.2 million, according to Tech.eu. Its software arm, Engine, signed Scotiabank's Tangerine as its first North American client.

Which UK payments companies lead in 2026?

Wise is the UK's largest listed payments fintech in 2026, moving $243 billion across borders in the year to March 2026 and switching its primary listing to Nasdaq in May. Checkout.com is the largest private UK payments processor by volume, handling more than $300 billion in 2025. GoCardless and TrueLayer lead bank-to-bank payments.

Wise

Wise began trading on Nasdaq under the ticker WSE on May 11, 2026, keeping a secondary London listing. For its fiscal year to March 2026 it reported $243 billion of cross-border volume, up 31%, net revenue of $2.5 billion and $39 billion of customer balances, according to Crowdfund Insider. Our explainer on mid-market rates and zero-fee transfers covers how its pricing compares.

Checkout.com

London-based Checkout.com processes online card payments for large merchants. It said in February 2026 that processed volume passed $300 billion in 2025, up 64%, with net revenue up more than 30% and full-year adjusted EBITDA margin above 10%, per its newsroom. A September 2025 staff share buyback set a $12 billion valuation.

GoCardless

GoCardless runs direct debit and open banking collections for subscription and invoice businesses. In the year to June 2025 its revenue rose about 18% to £155.5 million, payment volume doubled to £79.2 billion after the Nuapay acquisition, and its loss narrowed to £25.5 million, according to Tech.eu. It posted its first adjusted EBITDA-positive quarter in the final quarter of that year and expects a first EBITDA-positive full year in 2026.

TRTrueLayer

TrueLayer provides open banking payment APIs in the UK and Europe. It processed 188 million transactions in 2024, up 84%, on revenue of £20.3 million and a pre-tax loss of £38.6 million, as Tech.eu reported from its accounts. Its numbers are small next to card processors, which is the point: account-to-account payments in the UK are still early.

Which UK lenders, savings and banking infrastructure firms stand out?

By profit, OakNorth is the largest UK fintech lender in 2026, earning £223 million before tax in 2025 on a £7.2 billion loan portfolio. Zopa reported £65 million of underlying profit, Moneybox reached £23.2 billion in assets under administration by mid-2026, and ClearBank, which provides clearing to other fintechs, posted a third year of UK profit.

OakNorth

OakNorth lends to growing mid-sized businesses. In 2025 it earned £223 million before tax, grew new originations 33% to £2.8 billion and expanded its loan facilities portfolio to £7.2 billion, with the US accounting for 40% of new lending, according to Crowdfund Insider.

Zopa

Zopa, a lender turned bank, reported 2025 revenue of £377.1 million, up 24%, and underlying profit before tax of £65 million, with 1.7 million customers and £6.4 billion of deposits, per the bank's own release. Its Biscuit current account signed up hundreds of thousands of customers within months of launch.

MOMoneybox

Moneybox offers savings, investing, pensions and Lifetime ISAs. By its second quarter of 2026 it had £23.2 billion of assets under administration, up 40%, 1.9 million funded customers and quarterly revenue of £41.2 million, up 52%, per its shareholder update.

ClearBank

ClearBank is a clearing bank for other fintechs and payment firms. In 2025 its normalised group revenue rose 34% to £121.6 million, UK pre-tax profit rose 53% to £12.2 million and payment scheme volumes jumped 57% to 262 million, though the group made a statutory loss of £16.7 million as it invested in Europe, according to its results.

How do the leading UK fintech companies compare?

As of October 2026, the UK's fintech leaders split between profitable licensed banks (Revolut, Monzo, Starling, Zopa, OakNorth), payments firms reporting volume (Wise, Checkout.com, GoCardless, TrueLayer) and specialist platforms (Moneybox, ClearBank). The table shows each one's latest dated metric.

Company	HQ	What it does	Latest dated metric
Revolut	London	Global finance app, now a full UK bank	£4.5bn revenue, £1.7bn PBT (2025)
Monzo	London	Digital bank, personal and business	£1.7bn revenue, 15.2M customers (FY to Mar 2026)
Starling	London	Digital bank, Engine software	£887m revenue, £217m PBT (FY to Mar 2026)
Wise	London (Nasdaq-listed)	Cross-border transfers and accounts	$243bn cross-border volume (FY to Mar 2026)
Checkout.com	London	Online card processing	$300bn+ volume (2025)
OakNorth	London	Mid-market business lending	£223m PBT (2025)
Zopa	London	Loans, savings, current account	£377.1m revenue (2025)
MOMoneybox	London	Savings, investing, pensions	£23.2bn AUA (Q2 2026)
GoCardless	London	Direct debit and open banking collections	£155.5m revenue (FY to Jun 2025)
ClearBank	London	Clearing bank for fintechs	£121.6m revenue (2025)
TRTrueLayer	London	Open banking payments	188M transactions (2024)

What does revenue per customer reveal? A worked example

Dividing revenue by customers in the latest year shows Revolut earns about £66 per customer, Monzo about £112 and Starling about £143. Revolut's lower figure reflects a huge international base of lighter users, yet it converts revenue into profit far more efficiently, with a margin near 38% against roughly 10% at Monzo.

The arithmetic: Revolut's £4.5 billion over 68.3 million retail customers is about £66 each. Monzo's £1.7 billion over 15.2 million is about £112. Starling's £887 million over 6.2 million accounts is about £143. On profit, Revolut's £1.7 billion is 38% of revenue, Starling's £217 million is about 24% and Monzo's adjusted £172.6 million is about 10%.

Two lessons follow. Starling earns the most per customer because many of its accounts are main business accounts, and 56% of its SME customers use it as their primary bank. But it is also the most exposed to falling rates, which is why its revenue fell while the others grew. Monzo, still investing in Europe and mortgages, has the most room to widen margins if those bets work.

The UK's three big digital banks have the same app-shaped front end and three entirely different businesses behind it.

How is the UK regulating stablecoins in 2026?

The UK published final stablecoin rules in 2026. The FCA regulates all UK issuers, opening its authorisation gateway on September 30, 2026, and the regime goes live on October 25, 2027. The Bank of England adds stricter rules for issuers deemed systemic, including a £40 billion guardrail per coin, having dropped earlier proposed holding limits.

Under the FCA's policy statement, issuers must fully back coins, keep at least 10% in core assets such as on-demand deposits and short-term government debt, and redeem by the end of the next business day, according to Payment Expert. Systemic issuers must hold 30% at the central bank and 70% in short-dated gilts. ClearBank's chief executive argued the rules still make bank issuance hard to run profitably. Our detailed guide to the UK stablecoin regime covers the full rulebook.

What should you watch in UK fintech next?

The key dates for UK fintech are the FCA stablecoin gateway, open from September 30, 2026 to February 28, 2027, the regime's go-live on October 25, 2027, and Revolut's aim of 100 million customers by mid-2027. Whether funding recovers from a decade low will decide which younger London fintechs reach the scale of this list.

• Now to February 28, 2027: FCA authorisation gateway for stablecoin issuers and crypto firms.
• October 25, 2027: UK stablecoin and cryptoasset regime goes live.
• Mid-2027: Revolut's target of 100 million customers, alongside its pending US banking licence application filed in March 2026.
• Listings: Wise's Nasdaq move is a test case. A strong run would encourage Revolut, Monzo or Starling to list in New York rather than London.
• Remittance pricing: Competition from Wise and Revolut keeps pushing down the cost of sending money from Britain, as our UK to India money transfer guide shows.
