- The UK remains a highly competitive market, with major US firms, European banks and UK domestic banks all vying for market share.
- Boutique advisory plays (Evercore, Centerview, Rothschild) are increasing in prominence in the UK, reflecting demand for independent advice.
- Some UK-based banks (e.g., the domestic retail banks) may have investment-banking arms, but the large bulk of UK investment banking deal-flow is still handled by major global players operating in London.
- The ranking of “top 10” can vary depending on criteria (fees, deals, advisory vs full-banking etc.); the firms above are selected for relevance to UK investment banking in 2025.
Why this matters
- For UK corporates, choosing among these firms defines access to capital markets, M&A execution, global reach and sector-expertise.
- For investors and talent, the prominence of London-based investment-banking operations signals where career and deal-activity hubs remain.
- For the UK market, the competition among these firms influences London’s status as a global investment-banking centre.
