The Data (Use and Access) Act 2025, chapter 18 of that year, was enacted on 19 June 2025. It covers access to customer and business data, digital verification services and data protection, and it creates a new Information Commission.
The Act's passage through Parliament turned into a contest over AI. Peers led by Baroness Kidron kept writing in a duty on AI developers to reveal their use of copyright works, and the Commons struck it out every time. After five rounds of ping-pong the Lords conceded in June 2025.
In place of that disclosure duty, sections 135 and 136 oblige ministers to publish an economic impact assessment and a report on copyright and AI within nine months.
