Digital Regulation
Competition and digital-markets regulation for firms designated, challenged or investigated under the UK and EU regimes
The Competition and Markets Authority now sets the terms on which the largest platforms trade, and those terms decide how other businesses reach their customers. Under the Digital Markets, Competition and Consumers Act 2024 the CMA may designate a firm with strategic market status and impose conduct requirements and pro-competition interventions on it. The EU Digital Markets Act imposes a parallel regime on gatekeepers. Bratby Law advises on strategic market status designation, conduct requirements, pro-competition interventions, Digital Markets Act compliance, the concurrent competition powers held by Ofcom and the Financial Conduct Authority, and merger control in digital markets. Rob Bratby leads every matter himself, with thirty years in telecoms, competition and digital-markets regulation behind the advice.
This work is for a platform facing designation, a conduct requirement or a pro-competition intervention and needing the regime read against its own business; for a challenger that depends on access to a designated platform and wants the obligations enforced; for founders and investors who need the regulatory risk in a digital business priced before a deal; and for City firms needing specialist digital-markets co-counsel alongside a wider competition or corporate instruction. The depth is where competition law meets telecoms, data and payments, from the CMA's first strategic market status decisions to the divergence between the UK and EU regimes.
The regulatory framework
UK digital-markets regulation rests on the Digital Markets, Competition and Consumers Act 2024. Under Part 1 the Competition and Markets Authority may designate a firm with strategic market status in a digital activity and then impose conduct requirements and pro-competition interventions on it. The EU Digital Markets Act binds designated gatekeepers under a separate regime.
The Digital Markets, Competition and Consumers Act 2024 created the strategic market status regime in Part 1. The Competition and Markets Authority may designate a firm that holds substantial and entrenched market power and a position of strategic significance in a digital activity, subject to a turnover condition. Designation lasts five years. Conduct requirements set enforceable rules of fair dealing, open choices and trust and transparency on the designated firm. Pro-competition interventions require structural or behavioural change where the CMA finds an adverse effect on competition. Where a designated firm breaches a conduct requirement without reasonable excuse, the CMA may impose a civil penalty of up to ten per cent of its worldwide turnover, or of its group's worldwide turnover where it is part of a group.
The EU Digital Markets Act designates gatekeepers that operate core platform services under Article 3 and imposes self-executing obligations under Articles 5 to 7, enforced by the European Commission with fines of up to ten per cent of worldwide turnover. A UK business that supplies an EU core platform service can fall under both regimes at once. Alongside the digital rulebook, the Competition Act 1998 Chapter I and Chapter II prohibitions and the market investigation powers in the Enterprise Act 2002 continue to apply. Ofcom, the Financial Conduct Authority and the other sectoral regulators hold concurrent competition powers under the Competition (Concurrency) Regulations 2014, so a single digital practice can engage the CMA and a sector regulator on the same facts.
The regime is in its opening phase. The CMA designated Google in general search services on 10 October 2025 and Apple and Google in their mobile platforms on 22 October 2025, and opened a strategic market status investigation into Microsoft's business software on 14 May 2026. The EU is designating cloud services as core platform services while the UK holds back. The two regimes are already diverging on scope and remedy, and a firm that tries to comply with both at once has to reconcile them itself. Any platform business now carries digital-markets regulation as a continuing regulatory risk alongside telecoms, data protection and payments.
Digital-markets advice
Designation for strategic market status, conduct requirements, pro-competition interventions, EU Digital Markets Act compliance, the concurrent competition powers of the sector regulators, merger control in digital markets, and market investigations and enforcement each raise a separate question for a platform business and for the firms that deal with it.
Why digital regulation matters
The CMA now decides which platforms trade under supervision and on what terms. A strategic market status designation reshapes how a platform prices, ranks and contracts, and the CMA can require it to change a commercial term that took years to build. The CMA and the European Commission are writing the rules of digital competition case by case, and the first decisions set the reference points for everything that follows. For a challenger, the same regime opens access to a platform that was closed. For an investor, digital-markets exposure now belongs in the diligence, priced as a live regulatory risk. Firms that try to operate between the UK and EU regimes without reconciling them end up paying for both.
Perspectives on the regime
The platform, the Advisor and the investor each see a different part of the regime.
The Platform's Perspective
A designated firm has to run its business under conduct requirements it did not write. The task is to comply without conceding more than the rule demands, and to keep the commercial model intact while the CMA tests it. Each conduct requirement has to be read against the actual product rather than against a template.
The Advisor's Perspective
In Rob Bratby's view, the strategic market status regime is the most consequential shift in UK competition law since the Enterprise Act 2002. It moves from prohibition after the fact to supervision in advance. A firm that engages early, on the designation test and the first conduct requirements, shapes the regime it will live under; a firm that waits inherits one written around it.
The Investor's Perspective
Digital-markets regulation changes the value of a platform asset. Designation caps some revenue lines and opens others, and a pro-competition intervention can reset a business model mid-hold. An investor has to price that risk in a digital target, establish whether a designation would apply to it, and decide what that means for the deal.
Taken together, those three perspectives describe how the CMA, the European Commission and digital businesses actually operate.

Designation, conduct requirements and Digital Markets Act compliance
Frequently asked questions about digital regulation
What is strategic market status under the DMCC Act 2024?
Strategic market status is a designation the Competition and Markets Authority can apply to a firm with substantial and entrenched market power and a position of strategic significance in a digital activity, above a turnover threshold. Designation lasts five years, and the CMA may then impose conduct requirements and pro-competition interventions on that firm.
Does the EU Digital Markets Act apply to a UK business?
It can. The Digital Markets Act binds a firm designated as a gatekeeper of a core platform service under Article 3, wherever it is based, if it provides that service to business and end users in the EU. A UK platform that meets the thresholds falls under the EU regime as well as the UK strategic market status regime, and has to comply with both.
What is the difference between a conduct requirement and a pro-competition intervention?
A conduct requirement is a standing rule of fair dealing, open choices or transparency that the CMA sets for a designated firm. A pro-competition intervention is a targeted remedy, structural or behavioural, that the CMA imposes after finding an adverse effect on competition. Conduct requirements govern day-to-day behaviour; interventions change the underlying position.
What are concurrent competition powers?
Ofcom, the Financial Conduct Authority, Ofgem and the other sector regulators hold the same Competition Act 1998 enforcement powers as the CMA within their sectors, under the Competition (Concurrency) Regulations 2014. A single set of facts in a regulated digital market can engage a sector regulator and the CMA at once, and the concurrency rules decide who leads.
Is AI regulation part of digital regulation?
No. Bratby Law treats AI as a data protection matter, framed as data protection for AI-enabled products, and advises on it within the Data Protection practice. Digital regulation here means competition and digital-markets regulation: strategic market status, the Digital Markets Act and concurrent competition powers.
How does digital-markets regulation interact with telecoms, data and payments?
Closely. A conduct requirement on a platform can depend on how it handles personal data, a concurrency question can put Ofcom or the FCA in the lead, and a digital merger can raise both competition and sectoral issues. A single matter can therefore cross telecoms, data protection and payments regulation at once.
