Market Studies & Investigations

2025 was a fascinating year for UK competition and consumer enforcement, with the CMA changing its policies and practices in a number of areas. Our Year in Review summarises the most important developments of the past year and what we expect in 2026, as the CMA implements its reworked procedures for merger and market cases, begins to use its new consumer fining powers, and imposes digital conduct requirements for the first time. We also anticipate a Government consultation on significant changes to the decision-making model for mergers and markets.

As part of our response to the European Commission’s consultation on possible reforms to its merger guidelines,[1] we provided our views on Topic Paper B – Assessing Market Power.

On 25 January 2024, the Microeconomics Unit[1] of the Competition and Markets Authority (CMA) published a report examining competition and market power in UK labour markets (the Report).  The Report is the Unit’s first published work, covering developments in the labour markets over the last two decades.  Over this period, labour markets have changed significantly through the rise of flexible working and the gig economy (defined as labour services contracted through digital platforms), changes in restrictive covenants (contract clauses that restrict what workers can do after they leave their current employer), and shifts in pay-setting policies.  Each of these factors has the potential to impact employer market power.[2]
