Question to the Home Office:

To ask the Secretary of State for the Home Department, what consideration she has given to the potential merits of making the adoption of validated alternatives to animal methods a binding requirement rather than a discretionary aid under Section 2A of the Animals (Scientific Procedures) Act 1986.

The Animals (Scientific Procedures) Act 1986 already provides a binding statutory requirement to use a non-animal method where a scientifically satisfactory method or testing strategy that does not involve protected animals is reasonably and practicably available. Compliance with this requirement is considered as part of the assessment and authorisation of project licences. The Government therefore does not consider that alternatives are merely a discretionary aid, or that a further statutory mechanism is required to make their use mandatory.

Formal validation can support confidence in and regulatory acceptance of a non-animal method, but validation alone does not determine whether that method is scientifically satisfactory for every proposed use. That assessment must take account of the method’s relevance, reliability and practical availability for the particular scientific purpose.

The Government is committed to accelerating the development, validation and uptake of non-animal methods. Its November 2025 strategy, led by the Department for Business, Innovation, Science and Trade and backed by £75 million, sets out measures to strengthen validation, regulatory confidence and adoption, while maintaining robust standards of scientific quality and human, animal and environmental protection
