Question to the Home Office:

To ask His Majesty's Government, in regard to the Animals (Scientific Procedures) Act 1986: Non-technical summaries for projects granted in 2025, January to March, what steps they are taking to end invasive brain research on non-human primates and other animals.

All applications must conform with all legal requirements set out in the Animals (Scientific Procedures) Act 1986. This includes, applying the principles of the 3Rs (Replacement, Reduction and Refinement); the replacement of animals with alternatives, the reduction of the number of animals used to the minimum possible and the refinement of any techniques to reduce the harm suffered by the animals to the minimum.

The Home Office conducts a robust and rigorous harm benefit assessment which requires a detailed justification of the harms, and which demonstrates the 3Rs have been fully considered. All licence holders have a responsibility to fully implement the 3Rs throughout the lifetime of a licence and demonstrate this requirement at audit.

The Department for Science, Innovation & Technology (DSIT), the Home Office and DEFRA are engaging with stakeholders to finalise a strategy to accelerate the development, validation and uptake of alternatives to animal testing which is scheduled for publication later this year.
