According to the latest Annual Statistics of Scientific Procedures on Living Animals, Great Britain, around 2.54 million scientific procedures involving living animals were carried out during 2025.
While this represents a 3.8% decrease compared with 2024, animal welfare charity Naturewatch Foundation believes progress is happening far too slowly.
The figures also reveal that over 17,500 procedures were classified as severe, meaning the animals involved experienced significant pain, suffering or distress. Of particular concern to the charity is the rise in the number of certain species being used for the first time.
The number of beagles increased from 1,593 to 1,640, while the number of non-human primates rose sharply from 1,478 to 1,845. The use of horses also increased, climbing from 60 to 100.
Naturewatch Foundation argues that these increases sit uneasily alongside the Government's commitment to phase out animal testing by investing in modern, human-relevant alternatives.
Laura Lendrum, Animal Experiments Campaign Manager at Naturewatch Foundation, said the latest statistics show there is still a long way to go.
She told That's Green that she welcomed the overall reduction in animal use but expressed concern that the number of beagles, primates and horses had increased. She said the Government's pledge to phase out animal testing now needs to be reflected in the statistics through a much faster shift towards research methods that are both more reliable for humans and avoid the use of animals altogether.
Scientists are increasingly developing innovative alternatives, including advanced cell cultures, organ-on-a-chip technology, computer modelling and artificial intelligence. Supporters believe these approaches can provide results that are more relevant to human biology while reducing the need for animal experiments.
Naturewatch Foundation hopes the Government's recently announced strategy, developed alongside researchers, industry and animal welfare organisations, will deliver measurable progress in replacing animal testing with these emerging technologies.
The charity is also encouraging consumers to play their part by supporting companies committed to cruelty-free practices. Its Compassionate Shopping Guide helps shoppers identify brands that do not benefit from animal testing, allowing purchasing decisions to contribute towards a future where scientific innovation and animal welfare go hand in hand.
For many campaigners, the latest figures serve as a reminder that while progress is being made, there is still considerable work ahead before animal testing becomes a thing of the past.
