Its client focus spans both domestic organisations and international entities with UK operations.

Deloitte UK’s headquarters is located in the United Kingdom, with a presence in multiple cities across England, Scotland, Wales, and Northern Ireland. As part of the Deloitte network, it shares global resources while operating as a distinct UK entity. Ownership of the firm rests with its partners, and it is structured as a UK private company limited by guarantee under Deloitte Touche Tohmatsu Limited.

This incident has been noted in public ransomware trackers as an example of the evolving threat landscape confronting the sector.
