Animal Experiments
The question
To ask the Secretary of State for the Home Department, with reference to the Annual Statistics of Scientific Procedures on Living Animals, Great Britain 2024; published on 23 October 2025, what assessment her Department has made of trends in the (a) number and (b) types of procedures carried out compared to the previous year.
Answered by Dan Jarvis
In 2024, there were 2.64 million regulated scientific procedures carried out in Great Britain involving living animals. This is a decrease of 1% on the previous year, and the lowest number since 2001.
The trends in the number of animals and types of procedures carried out each year are linked to the volume and nature of scientific work undertaken and products being brought to market.
The Home Office is responsible for regulating under the Animals (Scientific Procedures) Act 1986 (ASPA) to assure compliance with protections afforded to animals used in science. Trends in requirements are the responsibility of other authorities. For instance, regulatory requirements for animal testing are the responsibility of the relevant regulators, such as the Medicines & Healthcare products Regulatory Agency (for medicines) and Health and Safety Executive (for chemicals).
