Question to the Home Office:

To ask the Secretary of State for the Home Department, what assessment has her Department made of the potential merits of introducing a statutory mechanism to ensure that validated non-animal models replace animal procedures under 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
