Today's the Day: EU AI Act Transparency Obligations Are Live, and Your Client Intake Form May Already Be Non-Compliant

2 August 2026. Mark it.

The Omnibus agreement of May 2026 was, by Brussels standards, good news. The EU Parliament endorsed the package on 16 June, the Council gave final approval on 29 June, and the headline high-risk AI deadline moved from today to 2 December 2027: a 16-month reprieve that caused a great many compliance managers to exhale, cancel their August holiday cancellations, and quietly tell their boards that the immediate pressure had passed.

It had not.

Article 50 of the EU AI Act, covering transparency obligations, was not part of the Omnibus deferral. It lands today, 2 August 2026, as scheduled, as confirmed, and with the force of directly applicable EU law that reaches UK businesses serving EU customers regardless of where those businesses are domiciled. If your firm uses a client-facing chatbot, that chatbot must now identify itself as an AI system. If your document generation tool produces synthetic content, it must carry machine-readable markers. If any system in your workflow deploys emotion recognition, the user must be told. These are not aspirational guidelines. They are enforceable obligations as of this morning.

Professional services firms, solicitors, accountants, company secretaries, formation agents, have spent 2026 deploying AI tools at pace. Research from the British Chambers of Commerce and Atos, published in March, found that 54% of UK firms were actively using AI by 2026, up from 35% in 2025 and 25% in 2024. The sector attracted by AI fastest has not been manufacturing. It has been legal and advisory services, where large language models were the most widely used AI technology among UK businesses as of June 2026. The same firms, it turns out, have been largely neglecting the one filing category most directly associated with protecting the brands being built on top of those tools.

Class 45 Filings Are Collapsing

AIBD analysis of UK Intellectual Property Office Trade Mark Database (TMD) data shows 617 Class 45 trademark filings in Q3 2026 to date, a fall of 61.2% against the equivalent prior period. Class 45 covers legal services, security services, and personal and social services: the exact classification under which law firms, compliance consultancies, and legal technology brands would ordinarily protect their service marks.

The irony is architectural. Firms are building AI-enhanced legal service offerings at speed, adopting the tools, retaining the clients, and generating the revenues, while neglecting to protect the brand names under which they are doing all of it. The 13th edition of the Nice Classification, which came into force on 1 January 2026, added notary services expressly to Class 45, reflecting WIPO's ongoing effort to bring the classification system into line with how professional services actually operate. The IPO charges £205 for the first class online, plus £60 per additional class; fees are non-refundable if refused. Against the cost of brand litigation, it is not an extravagant sum.

A clearance search before filing remains the obvious first step, and it remains the step most commonly skipped. Applications that proceed without adequate prior art clearance face the twin risks of refusal, after which the fee is gone, and post-registration opposition from earlier rights holders, after which the fee is also gone, along with several months of a trade mark attorney's time.

What This Means for Your Monday Morning

The first working Monday of August 2026 comes with a full in-tray.

If any client-facing AI system in your practice touches EU users, Article 50 transparency disclosures are required today. Not next quarter. Not when the formal enforcement guidance is published. Today. The obligation requires that AI chatbots identify themselves as such, and that synthetic content be marked. The practical steps are a transparency notice audit of every client-facing tool, a conversation with your DPO before close of business, and a vendor review to confirm that third-party tools your firm deploys are themselves compliant.

Check the SIC 2026 transition. The ONS finalised the SIC 2026 framework in April 2026, with AI-related activities now explicitly recognised as separate classifications at the five-digit level. When Companies House mandates the transition, which the guidance confirms will come via the Confirmation Statement (CS01) process, firms will update their registered activity codes on the next filing cycle. The online CS01 fee is £50. Not urgent today, but correlation tables are being developed and automated matching tools are in preparation, so the transition should be smooth for the majority of legal and secretarial firms whose core SIC codes sit in the unchanged 99.4%.

The ECCTA compliance environment is also materially tighter than it was twelve months ago. Companies House now has stronger powers to query and reject information, filings need to be accurate on first submission, and identity verification for directors and persons with significant control is under heightened scrutiny. For firms acting as registered agents or secretarial service providers on behalf of clients, the due diligence burden has increased. The margin for error is smaller.

The Workforce Is Not Keeping Up

The compliance profession is hiring. Legal services and specialist compliance roles are among the sectors driving hiring optimism in 2026, according to Robert Walters' salary survey data, but demand for skilled compliance and risk advisory talent continues to outstrip supply. Wage inflation in insurance and legal remains concentrated at the specialist end, which is precisely where AI governance expertise now sits. The Employment Rights Bill adds further complexity: day-one rights and tighter procedural requirements mean that firms taking on compliance staff face more demanding employment law obligations at the point of hire.

AI has not, so far, resolved the headcount problem. ONS data from its AI in UK Businesses 2023-2026 survey shows that around half of businesses report AI has had no impact on workforce headcount, with a smaller proportion, just under 7% among medium-sized businesses, reporting actual reductions. Among businesses actively using at least one AI technology, only 10% report using it extensively. The tools are in the room. The workflows have not been transformed.

The Next Deadline on the Horizon

For professional services firms with EU exposure, 2 December 2026 is the next fixed date: the transparency obligation for AI-generated content watermarking under the Omnibus revised schedule. Annex III high-risk systems, recruitment tools, credit scoring, access-to-essential-services AI, must comply by 2 December 2027. Annex I product-embedded systems have until 2 August 2028.

None of which is an excuse for leaving Article 50 unattended on today's desk. The Brussels delay is real. The transparency obligation is not delayed. And if your client portal has an AI assistant that has not introduced itself, it should do so before lunchtime.
