Significant events

• “Development of a new temporary exhibition, The Age of AI, funded by UK Government, commenced in 2024 with the exhibition officially opened on 6 February 2025 by Feryal Clark, MP and Parliamentary Under-Secretary for the Department for Science, Innovation and Technology.”
• “The renovation of Block B will re-open the upper gallery to the public, make the Block accessible by installing a lift to all levels from the lobby and remove post-war additions in those spaces. Two new exhibitions will be created; the exhibition in the lower gallery will focus on the life and work of Alan Turing, and the exhibition in the upper gallery will explore why and how messages are concealed using codes and ciphers. This exhibition will explore the machines that helped the encryption and the people involved in designing and using the machines and systems.”

Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers
