Animal Experiments

The Animals (Scientific Procedures) Act 1986 (ASPA) provides a robust and rigorous regulatory framework that protects animals used in science. It requires that the principles of the 3Rs - replacement, reduction and refinement - are followed so that animals are only used where there are no alternatives, the minimum number of animals are used, and the most refined procedures for using animals are employed to minimise harm. Work is being undertaken to restate and replace EU provisions within domestic law following EU exit. This will ensure we retain the highest standards for animal protection. At this time, there are no further changes planned to ASPA, but this legislation is kept under review.

In 2023, the Animals in Science Regulation Unit (ASRU) undertook a comprehensive exercise to review its operating model and organisational design which identified where changes could be made to enhance its regulatory effectiveness. On 14 October 2024, the Government announced via written ministerial statement that ASRU would make reforms to its organisational design to most effectively deliver its purpose of protecting animals through maintaining compliance with ASPA.
