Progress in delivering the objectives of the strategy will be measured against a set of KPIs developed in consultation with delivery partners. A KPI framework covering the strategy's commitments will be published later this year.

While a unified reporting format that captures investments made through all relevant government departments and regulatory bodies is not yet available, individual delivery partners are developing and refining their reporting methodologies.

We are supporting the development, validation and international acceptance of alternative methods, including through the forthcoming UK Centre for the Validation of Alternative Methods (UKCVAM), engagement with international regulators and participation in OECD test guideline programmes. We are also strengthening bilateral and multilateral partnerships to support the global uptake of validated alternatives, helping to reduce reliance on animal testing while maintaining high standards of human, animal and environmental safety.

The Government is committed to ensuring that non-human primates used in scientific procedures are sourced responsibly and used only where no suitable alternative is available. In 2025, 1,845 non-human primates were used for the first time in scientific procedures in Great Britain. All marmosets, tamarins and rhesus monkeys were born at licensed establishments in the UK, while the majority of cynomolgus monkeys were born overseas, but were not sourced from the wild.

Following advice from the Animals in Science Committee, the Home Office strengthened its sourcing requirements from 1 August 2025 so that non-human primates should come from established captive-breeding populations rather than being sourced from the wild. These requirements are supported by a time-limited transitional arrangement and a commitment to review their operation.

The Government supports the use of UK-bred non-human primates where suitable animals are available. However, sourcing decisions must take account of scientific requirements, animal welfare, biosecurity and the availability of appropriate breeding populations. The Home Office will continue to monitor sourcing data and the effect of the strengthened requirements.

The Government is also investing £75 million through its strategy to support the development, validation and uptake of alternatives to animal use.

The Government remains committed to reducing and replacing the use of animals in science, including dogs. Under the Animals (Scientific Procedures) Act 1986 the statutory principles of Replacement, Reduction and Refinement require animals to be used only where there is no scientifically satisfactory alternative, in the minimum numbers necessary, and with procedures refined to minimise suffering. Through the Replacing Animals in Science strategy, we are accelerating the development, validation and regulatory uptake of alternative methods, supported by investment, regulatory reform and strengthened delivery oversight. The strategy sets out a long-term vision to eliminate animal use in science wherever possible.

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

Dogs are a specially protected species under the Animals (Scientific Procedures) Act 1986. They may only be used in research where the applicant demonstrates that the scientific objective cannot be achieved using a scientifically satisfactory non-animal method or by using another species. Every proposed programme of work is assessed by the Animals in Science Regulation Unit (ASRU) to assure that the use of animals is justified by the expected benefits, the minimum number of animals are used, and procedures are refined to minimise suffering.

The Government committed to accelerating the replacement of animals in science wherever scientifically possible. In November 2025, the Government published Replacing animals in science: a strategy to support the development, validation and uptake of alternative methods, backed by £75 million in funding. The strategy includes specific commitments to reduce the use of dogs in science by 2030.

It is not possible to provide an overall funding figure for research councils funding for animal-based research and the development of non-animal methods, as funding is not generally allocated to UKRI based on specific research approaches. UKRI funds research on the basis of scientific excellence and need. Through its standard funding processes, UKRI only supports research involving animals where no scientifically acceptable non-animal alternative exists and where researchers have properly considered and applied the principles of replacement, reduction and refinement (the 3Rs). UKRI also supports non-animal approaches, including through investment in the National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs).

The UKRI Gateway to Research portal does not record whether projects involve the use of live animals under the Animals (Scientific Procedures) Act 1986. Information is held separately by individual research councils and is not available as a UKRI-wide figure. The Medical Research Council identified 181 relevant grants in 2022, 166 in 2023, 155 in 2024 and 116 in 2025. Equivalent data for 2021 are unavailable. These figures exclude relevant research supported through MRC units and institutes, which is not reportable by calendar year. The Biotechnology and Biological Sciences Research Council identified 74 relevant awards in 2021, 58 in 2022, 76 in 2023, 68 in 2024 and 56 in 2025.

His Majesty’s Government has not made an estimate of the total amount of funding provided across all Government departments for scientific research involving the use of live animals. Public funding for research involving animals is provided through a range of organisations and programmes that support broader scientific and medical research objectives. These organisations and programmes have different data collection and reporting systems in place, and therefore this information cannot be consistently identified across Government.

His Majesty’s Government has not made an estimate of the total amount of funding provided across all Government departments for scientific research involving human-specific research methods and technologies. UK Research and Innovation (UKRI) invests in a range of research that supports human-specific approaches, including organ-on-a-chip technologies, cell-based assays, functional genomics and computer modelling. These activities are generally categorised within broader research programmes, and funding for human-specific research methods is not separately identified across Government.

The Government is carefully considering the implications of the recent Upper Tribunal judgment concerning Section 24 of the Animals (Scientific Procedures) Act 1986 and Article 10 of the European Convention on Human Rights. Section 24 will remain in force while that work is undertaken.
