London’s investment banks and law firms have earned upwards of £1.2bn in fees this year, driven by a sharp jump in takeovers of UK-listed companies, according to filings and market data. The rush of deal activity has highlighted how concentrated gains in the City can be at a time when households face cost-of-living pressure.
Dealmaking explodes as overseas buyers pounce
Data from the London Stock Exchange show mergers and acquisitions involving companies listed in the UK rose by 175% in 2026, reaching about $132.9bn (roughly £100bn). The spike was fuelled by an influx of private equity capital and acquisitive buyers from the United States, who have been purchasing undervalued British businesses at record rates.
The pick-up in transaction volumes translated into large advisory fees. Official filings indicate that fees paid to investment bankers, lawyers and accountants working on the wave of deals exceeded £1.2bn, helping to underpin multimillion‑pound pay packets across the City.
Who benefited?
- JP Morgan advised on the most UK-related takeovers this year — 14 deals worth a combined $89.4bn (£67.6bn), the LSE found.
- Slaughter and May was identified as the leading law firm advising on the highest number of transactions.
- The largest individual transaction cited was the £10.6bn takeover of Intertek by EQT, which was reported to be expected to generate more than £370m in fees for advisers.
The advisory windfall is occurring against a backdrop of changes to banker pay. Since the UK government removed a cap on bonuses that was set at twice annual salary in late 2023, large banks have set their own limits. Some institutions now permit pay‑outs many times an individual’s base salary, and top performers can secure particularly large packages.
Tax debate and wider consequences
The bumper fees have arrived while the banking sector is actively resisting proposals to raise taxes. Banks in the UK already face a higher corporation tax rate of 28% compared with the standard rate of 25%, plus an additional surcharge related to their balance sheets. Senior industry figures have warned against potential tax increases in an upcoming budget.
For South African readers, the story underscores several cross‑border themes:
- How waves of international private equity and strategic buyers can reshape ownership of listed companies and concentrate value in advisers rather than operating businesses.
- The link between transaction-driven fee income and high bonus pools in investment banking, which feeds public debate about fairness and tax policy.
- Potential knock‑on effects for global capital markets, including questions about the long‑term role of domestic stock exchanges when foreign buyers buy heavily into listed firms.
| Metric | Value (2026) |
|---|---|
| Value of UK-listed M&A | $132.9bn (≈£100bn) |
| Increase vs prior period | +175% |
| Advisory fees paid | £1.2bn+ |
| Top bank by deal value | JP Morgan — 14 deals, $89.4bn (£67.6bn) |
| Largest deal cited | Intertek takeover — £10.6bn |
While the immediate beneficiaries are advisers, the broader economy may feel effects in other ways. When takeovers lead to restructuring or delisting, jobs and local economic activity can be affected; similarly, high advisory fees and bonus pools become focal points in debates over corporate taxation and executive pay standards.
The episode also raises a governance question for markets. Heavy inbound buying of listed assets can erode the diversity of owners and reduce the pool of publicly traded investment opportunities. Regulators and market operators will be watching whether the trend persists and how it influences liquidity, capital allocation and the role of the London market in global finance.
For households tracking where wealth is being created, the numbers illustrate that much of the immediate value from a takeover boom can be captured by specialist advisers rather than being widely distributed through wages or consumer prices. As policymakers consider tax and regulatory settings, the distributional implications of concentrated fee income will remain part of the conversation.
“The spree of acquisitions has fed advisory business at the biggest banks and law firms in the City,” the London Stock Exchange said in its reporting.
