For years, companies have treated their Big Four audit relationship like a utility — reliable, predictable, and not worth thinking about too hard. Turn on the tap, the water flows. Sign the engagement letter, the opinion arrives.
This week should shake that complacency. Two stories landed within 24 hours that, taken together, paint a picture of an audit industry under genuine structural stress. And if you’re a CFO, finance director, or audit committee chair, the implications are more immediate than you might think.
KPMG Cuts 500 Jobs — Starting with Auditors
On Friday, KPMG UK told staff it was cutting more than 500 roles across its business, with the heaviest impact falling on its audit division. Around 440 assistant manager positions in audit are going, alongside roughly 120 advisory roles.
KPMG’s official line is that “current market conditions mean our attrition rates are very low,” forcing them to “right-size” certain areas. Translation: in a normal year, enough people leave voluntarily that headcount manages itself. This year, nobody’s leaving. So the firm is doing it for them.
That framing deserves scrutiny. Low attrition doesn’t happen in a vacuum. People stay when the job market outside is uncertain, when competitors aren’t hiring aggressively, or when moving firms offers little upside. All of those conditions point to a broader contraction in demand for traditional audit services — not a temporary staffing anomaly.
There’s also the AI factor. KPMG recently told its own auditor, Grant Thornton, that it wanted to pay less for audit services, arguing that AI-driven efficiencies should translate into lower fees. The irony is thick: a Big Four firm demanding that its auditor pass on cost savings from automation, while simultaneously cutting the human auditors whose roles that automation is meant to complement.
One KPMG insider told the Financial Times that cuts to advisory were “pretty devastating,” with senior executives concerned about the pipeline. When partners start worrying publicly about pipeline, something structural has shifted.
EY’s Legal Provisions Explode by 300%
On the same day, EY’s latest Companies House filing revealed that the firm had added £188 million in new claims-related provisions in a single year. That took its total claims provision from £44 million to £184 million — a fourfold increase that reflects the mounting cost of audit failures finally coming home to roost.
The bulk of this relates to “alleged professional negligence claims or regulatory matters.” EY paid out £48 million in cash on claims during the period, but the new provisions dwarf what was settled, suggesting the firm expects significantly more pain ahead.
The biggest shadow hanging over those numbers is the NMC Health case. The collapsed private hospital operator’s administrators, Alvarez & Marsal, pursued EY for £2.4 billion, alleging the firm provided unqualified audit opinions for accounts that were, to put it mildly, unreliable. The case ran for 15 weeks before Dame Clare Moulder, and just before judgment was handed down, EY reached a “confidential agreement” to settle.
Nobody outside the negotiating room knows the settlement figure. But when a firm books £188 million in new provisions before settling a £2.4 billion claim, the maths suggests the final number was not trivial.
This wasn’t EY’s only regulatory headache in 2025. The FRC fined the firm £6.5 million for the Thomas Cook audit failure and an additional £500,000 over a Scottish water company audit. These are symptoms, not isolated incidents.
What This Means — The Structural Picture
Strip away the corporate language and here’s what’s actually happening in the UK audit market:
Revenue pressure is real. The traditional audit model — labour-intensive, time-based billing, junior staff doing the groundwork — is being squeezed from both directions. Clients want lower fees. AI promises efficiency gains that firms are expected to pass on. But the investment required to build and deploy those AI systems is enormous, and the returns are uncertain.
Regulatory accountability is increasing. The FRC isn’t going away, and its successor body ARGA (whenever it finally arrives) promises even more teeth. Audit firms that historically treated regulatory fines as a cost of doing business are discovering that the costs are escalating faster than revenues.
Talent is being hollowed out. KPMG is cutting assistant manager roles — people three years post-qualification who form the backbone of audit delivery. These aren’t redundant back-office roles. These are the people who actually do the audit work. Cutting them saves money today but creates a capability gap that’s difficult to rebuild when demand returns.
Legal risk is crystallising. EY’s provisions tell us that the era of audit failures being quietly settled for manageable amounts is ending. Administrators and regulators are pursuing larger claims more aggressively, and courts are willing to let them run.
What CFOs Should Be Doing
If your audit committee’s last conversation about auditor risk was “we’ll renew the engagement letter,” it’s time for a more serious discussion. Here’s what should be on the agenda:
Assess your auditor’s bench strength. If your audit is delivered by a Big Four firm that’s just cut 10 per cent of its audit workforce, ask the hard question: who’s actually doing the work on your engagement? Are the same people who planned the audit still available to execute it? Firms will reassure you that “service quality won’t be affected.” Get that in writing, with specifics.
Understand the AI transition. Every Big Four firm is deploying AI tools across audit workflows. That’s not inherently bad — AI can genuinely improve consistency and catch anomalies that humans miss. But there’s a transition period where firms are reducing headcount faster than the technology is proven. Ask your auditor what AI tools they’re using on your audit, what human oversight exists, and what happens when the model gets it wrong.
Review your auditor’s risk profile. EY’s legal provisions are public information. So are FRC enforcement actions against all the firms. Your audit committee should have a standing item that monitors your auditor’s regulatory and legal exposure. A firm fighting a multi-billion-pound negligence claim has divided attention, regardless of internal Chinese walls.
Consider the mid-tier alternative. For many UK businesses — particularly those outside the FTSE 350 — the reflexive assumption that only a Big Four firm can deliver adequate audit quality deserves challenging. Firms like BDO, Grant Thornton, Mazars, and RSM have invested heavily in capability and technology. In some sectors, their industry knowledge exceeds that of a Big Four team staffed with whoever happens to be available.
Don’t wait for the tender cycle. If you’re concerned about your auditor’s ability to deliver, you don’t have to wait for the standard rotation period to start a conversation. Market-test your audit. Invite proposals. At minimum, the process will give you data on what “good” looks like in the current market.
The Bigger Question
There’s a longer-term issue here that nobody in the profession wants to address directly: the Big Four model may be fundamentally misaligned with what the market needs from audit.
The model works by hiring large numbers of graduates, billing their time at multiples of their cost, and relying on natural attrition to manage headcount. It requires constant growth to sustain partner profits. When growth stalls — as it has in UK audit — the model breaks.
KPMG’s cuts and EY’s provisions aren’t aberrations. They’re the predictable consequence of an industry that has been slow to adapt its business model while facing simultaneous pressure from technology, regulation, and litigation.
For CFOs, the practical takeaway is straightforward: your audit is not a commodity, your auditor is not infallible, and now is the time to pay attention.
