Replacing animals in science

The UK Government has (11.11.2025) published its strategy for “Replacing animals in science”, to deliver on a key pledge from the Labour Party’s election manifesto to set out a clear plan to reduce and ultimately phase out the use of animals in research.

The Alliance for Human Relevant Science welcomes this turning point in government-led promotion of human-relevant science.

The roadmap: a starting point for change

The government’s strategy sets out a framework for how animal experiments will begin to be replaced in the UK. It introduces a tiered model for prioritising which tests can be phased out first, alongside a series of commitments aimed at supporting researchers, funders, and regulators to adopt non-animal methods.

The government describes this strategy as a beginning, with the long-term goal of eliminating animal use in “all but exceptional circumstances.”

A tiered approach to phasing out animal tests

The roadmap groups animal tests into three categories:

• Basket 1: Tests ready for rapid replacement
  Includes: pyrogen testing, skin and eye irritation, botox potency tests
• Basket 2: Tests needing further development
  Includes: forced swim test, fish toxicity, pharmacokinetic studies
• Basket 3: Tests with no current validated alternatives,
  Includes: fish endocrine disruption tests

Set phase-out targets

The government has committed to specific targets for a number of outdated animal tests, such as:

• Rabbit pyrogen test: to be phased out by the end of 2025
• Botulinum toxin potency testing: to be replaced by 2027
• Forced swim test: no new licences; existing ones expire by 2028

Commitments to support the transition

The strategy also includes a range of supporting actions to help embed non-animal methods across the research system:

• A new UK Centre for the Validation of Alternative Methods (UKCVAM) by 2026
• A £30 million preclinical translational models hub to develop human-relevant models
• ‘Validation Accelerator’ grants to fast-track promising alternatives
• A public dashboard of key performance indicators from 2026
• A restart of the public attitudes survey on animal research
• Foundational training in non-animal methods for early-career researchers
• Support for funders to scrutinise animal use more rigorously in grant decisions
• Regular publication of priority areas for alternative methods
• Encouragement for journal editors to publish studies using non-animal approaches
• Support the upskilling of regulatory assessors and enable engagement between regulators and companies to support the application of non-animal approaches
• A cross-governmental Ministerial group on alternative methods, chaired by the Science Minister

Together, these commitments signal a shift in how the UK approaches animal research, but they also highlight where further ambition is needed. Our Alliance and all partner organisations stand ready to help, encourage and support these actions wherever we can to drive progress and increase its scale and speed.

The entirely new tone from government, recognising that: “The benefits to addressing these barriers are far reaching and go beyond replacing the use of animals… delivering both scientific advancements and a meaningful cultural shift in animal use” is refreshing and wonderful to hear.

Celean Camp, Chair of the Alliance and CEO of Replacing Animal Research, says: “We’ve long argued that the replacement of animals in science cannot be driven without proper consideration and integration of issues around the development, validation and uptake of NAMs. I’m delighted to see the serious efforts around cross departmental working and integration of these areas including in this document. This strategy provides a springboard for UK life sciences to go further, faster, and we look forward to supporting funders, establishments, and researchers to put it into action.”

Reserve your place at our Royal Society event ‘A human focus for 21st century life sciences’ – 3 -4 Feb 2026

The Alliance is delighted to invite you to an exciting and unique two-day scientific meeting in London on 3rd and 4th February 2026: A human focus for 21st century life sciences
 
This free event is sponsored by the Royal Society and will be held at One Birdcage Walk.
 
This “science+” discussion meeting will showcase the transformative value of innovative, human-focused biomedical technologies, which are providing invaluable insights into human diseases and could underpin the development and optimal use of new and repurposed medicines. It will bring together researchers, clinicians, industries, regulators, policymakers and others to discuss key challenges and how to surmount them to accelerate their advantageous development and implementation. 

We are looking for your input, for lively discussions and a real exchange of ideas, to make this meeting of minds have tangible impact

To request an invitation to attend the event in person (only 200 spaces!) or register to watch online, please go to the Royal Society event page  
 
We hope to see you there!

It is wonderful that the government is currently working on a roadmap to phase out animal testing. But if it does not include specific targets and clear timelines, it will not alter the status quo, which is deeply entrenched and resistant to change.

Sign this petition to call for an ambitious and detailed UK roadmap for the phase-out of animal research and testing. This is a once-in-a-lifetime opportunity – we must make sure it really delivers!
