Question to the Home Office:

To ask His Majesty's Government what steps they are taking to ensure full compliance with the Animals (Scientific Procedures) Act 1986, in respect of the conditions in which living animals used for scientific purposes before and during these procedures are kept.

The Animals (Scientific Procedures) Act 1986 is enforced by the Animals in Science Regulation Unit (ASRU) in the Home Office which operates a robust regulatory framework to ensure that animals used for scientific purposes are kept in appropriate conditions both before procedures take place and throughout the conduct of those procedures.

ASPA requires a three-tier system of licensing covering establishments, projects, and individuals. All licensed establishments must comply with standards for animal protections set out in ASPA and in the Code of Practice for the Housing and Care of Animals Bred, Supplied or Used for Scientific Purposes which governs the accommodation, care, monitoring and veterinary oversight of the animals.

Licensed establishments are also required to have key named individuals in place, including veterinary surgeons and animal welfare officers, who are responsible for the health, care and welfare of animals and for advising on their use before and during regulated procedures. Establishments must operate local ethical review processes to provide ongoing oversight of animal welfare, review care and housing arrangements, and ensure that licence conditions are met.

ASRU assures compliance with these requirements through a programme of announced and unannounced audits. Any instances of non-compliance are taken seriously and addressed in accordance with ASRU’s published compliance policy, which provides for a range of regulatory responses, including enforcement action where necessary.

In 2025, ASRU implemented organisational reforms to strengthen delivery of its regulatory functions including increasing the size of its inspectorate, further enhancing oversight of animal protections across licensed establishments.
