Postcodes and Profiles of 20 UK FinTech Agencies (Descriptions and Addresses)

Good question. Compiling a list of 20 UK FinTech agencies / companies with detailed profiles and their postcodes is nontrivial — many directories don’t provide full postal addresses for all firms, especially for startups. But below is a carefully curated list of 20 prominent UK FinTech companies, along with descriptions and as precise address information as publicly available. I also include commentary on the selection.

20 UK FinTech Agencies / Companies — Profiles + Addresses

Here are 20 notable FinTech firms in the UK. (“Agency” is interpreted broadly: includes banks, payments companies, embedded finance, SME finance, digital banking, etc.)

Commentary & Analysis

• Diversity of FinTech: This list shows the breadth of FinTech in the UK: not just banks (digital challengers) like Revolut or Monzo, but also payments (Checkout.com), lending (Funding Circle, Kriya), “Buy Now, Pay Later” (Zilch), investing (Nutmeg), and green-finance (Yayzy).
• Innovation & Scale: Some companies are massive in scale (Revolut, Checkout.com), while others are more niche but innovative (Yayzy, Kriya). This mix is healthy for the ecosystem.
• Geographic Concentration: Many are headquartered in London, which remains a global FinTech hub. However, UK FinTech also has players outside London; but publicly listed head-office addresses often gravitate to London.
• Data Limitations: Even for well-known companies, getting precise postal addresses (down to the postcode) is not always easy from public directories. Many company profiles / “FinTech directories” focus more on business model than physical location.
• Regulatory & Growth Pressure: These companies operate in a heavily regulated space. Their growth depends on regulatory compliance (FCA, PRA) and on scaling their technology alongside managing risk.
• Good question. It’s quite difficult to find 20 UK fintech companies (“agencies”) with fully reliable publicly-available postcode-level addresses and in-depth profiles all in one place — many fintech firms are startups, scaleups, or don’t publish a detailed street address in public directories. But I can provide a detailed case-study style list of 10 prominent UK fintech companies, giving descriptions, known addresses (with postcodes where available), and commentary. After that, I’ll note challenges and make observations.

  Commentary & Analysis

  1. Concentration in London:
     • Most of the major fintech firms are based in London, reaffirming its status as the UK fintech hub.
     • This geographic concentration helps with access to talent, funding, and regulatory institutions (like the FCA), but may also concentrate risk (e.g., property cost, “London-only” ecosystem).
  2. Diverse Business Models:
     • The list includes a mix of neobanks (Revolut, Monzo), SME lenders / finance companies (Kriya, Allica), payments specialists (GoCardless), consumer credit (Zilch), and fintech software / B2B fintech (Meniga, 3AI).
     • This diversity is healthy: it shows fintech disruption across banking, payments, lending, and analytics.
  3. Growth Orientation:
     • Some of these firms (e.g., Monument, 3AI) are among the fastest-growing fintechs, showing strong market demand and potentially large future scaling. (Sifted)
     • High growth fintechs often face challenges: capital intensity, regulatory scrutiny, risk management, and scaling infrastructure.
  4. Address / Data Transparency:
     • While large fintechs like Revolut and Monzo clearly publish their registered office addresses (with postcodes), many are less transparent about their full operating offices or multiple offices.
     • For some fintech companies, only the city-level HQ is publicly available. This reflects a broader challenge in building a fully accurate and detailed directory of fintechs with precise postal addresses: many startups don’t disclose granular address data, or their offices change.
  5. Regulatory Risk:
     • FinTech companies, especially those offering banking (Allica, Monzo) or credit (Kriya, Zilch) are heavily regulated (FCA, PRA), which constrains their business models and imposes compliance costs.
     • However, regulatory engagement can be a competitive advantage: fintechs that build solid compliance infrastructure may win more trust from partners and customers.
  6. Opportunities:
     • SME fintech: There’s strong demand in UK SMEs for digital banking, lending, and cash-flow tools — firms like Kriya and Allica are well-positioned.
     • Embedded finance: As traditional companies adopt fintech capabilities, embedded finance (fintech services within non-financial companies) will likely continue growing.
     • Financial crime tech: With rising regulatory pressure, fintechs like Flagright (financial crime) could become increasingly important.

  Challenges / Limitations in This List

  • Not a full 20: Despite efforts, I could reliably verify detailed addresses for only 10 fintech firms. Many others are in fintech directories, but lack clear public head office addresses (or have only city-level HQ listed).
  • Data currency: Some directory sources may be out of date.
  • Company definition ambiguity: “FinTech” is broad; some companies in larger fintech directories are very small, very niche, or not purely financial-technology businesses.
