Google Search Advertising Competition Claim

Competition Claim Against Google: For abusing its dominant position in the search advertising market.

Any business that paid Google, directly or through an agency, for search advertising displayed in the UK between 1 January 2011 and 15 April 2025, may be entitled to compensation as part of a new collective legal action.

Case overview:

Google Search Advertising Competition Claim

We are bringing an opt out case against Google and its parent company Alphabet LLC for abusing its dominant position in search advertising. We believe that thousands of companies across England and Wales were overcharged by Google, who had abused their dominant position in the market to reduce competition.

The Case Against Google

On 27th May 2025, Mr Roger Kaye KC filed an application with the UK Competition Appeal Tribunal to bring collective proceedings against:

  • Alphabet Inc.
  • Google LLC
  • Google Ireland Limited
  • Google UK Limited

The proposed claim accuses Google of abusing its dominant position in the search advertising market, resulting in inflated costs and reduced competition, to the detriment of UK advertisers.

On 16 April 2025 Or Brook Class Representative Limited (“OBCRL”) filed a similar application based on substantively the same facts.

Following a consensual agreement between Mr Roger Kaye KC and OBCRL, Mr Kaye KC has joined the Brook team, with OBCRL now instructing both KP Law Limited and Geradin Partners, and Mr Kaye KC supporting the Brook claim as Chair of the Consultative Panel. Mr Kaye KC has agreed to stay his claim while Dr Brook’s consolidated £5 billion claim continues.
