Animals in Science Regulation Unit: Annual Report 2024

I beg to move,

That this House has considered the Animals in Science Regulation Unit annual report 2024.

It is always a pleasure to serve under you, Sir John, and it is a pleasure to introduce this debate. It concerns the use of animals in scientific research and the most recent Animals in Science Regulation Unit annual report for 2024, which was published in December 2025. The subject is important to me, to many of my constituents and possibly to up to half the population of these islands who have the pleasure—nay, the privilege—of sharing their lives with a pet.

I pay tribute to the work of the hon. Member for North Ayrshire and Arran (Irene Campbell), who leads the all-party parliamentary group on phasing out animal experiments in medical research, as well as to the work of Animal Free Research UK and its chief executive, Carla Owen, who is in the Public Gallery and was behind the Herbie’s law campaign. Herbie has unfortunately passed, but the campaign lives on. I also want to thank Cruelty Free International, which continues to champion the ending of animal research worldwide.

In this debate, I want to focus on the weak oversight of the regulations, which has led to shocking failures to protect animals from undue suffering; that has been highlighted in the Home Office report. The findings show just how much we are failing to prevent animals from suffering when they are used in scientific experiments, due to the incidence of non-compliance with the law or with licence conditions. The report focuses on numerous incidents from across 2024, which sadly included animals that have starved to death or drowned. Other animals were put into waste bags by mistake and others were kept alive beyond humane endpoints. The incidents in the report make for upsetting reading. I am a supporter of phasing out animal experimentation in medical research, and I believe this transition should be completed urgently. The very least we can do in the meantime for those animals used in laboratories is to ensure their welfare and minimise their suffering.

It is important to put the issue in context. In 2024, 2.64 million procedures using animals took place in UK labs: five animals used in research every minute of every day, representing a decrease of only 1.21% from 2023.

[Alex Easton (North Down) (Ind)]

Given the more than 2.6 million procedures and the small year-on-year decrease, does not progress on replacing the use of animals in science remain only incremental? What is needed is a truly transformational shift. Does the hon. Member accept that, unless urgent and ambitious progress is made, public confidence will continue to be undermined on this issue?

[Seamus Logan]

I completely agree; that is the point that I am trying to draw out.

There were 2,646 procedures on dogs and 1,936 on non-human primates. Examples include non-human primates being subjected to invasive brain surgery and deprived of fluid to induce them to perform behavioural tasks and mice being given psychostimulant rewards such as cocaine or amphetamines—and this, under licence conditions. However, the ASRU report highlighted instances in which compliance with these licence conditions was not followed; there have been failures to provide adequate care and failure to provide food and water, which are the most basic welfare needs of animals being held in laboratories across the UK.

In one very distressing incident, it is reported that a mother was removed from its cage and killed, resulting in unweaned pups starving to death. In 2024, there were 146 cases of non-compliance in British laboratories, a 16% decrease from the 169 cases reported in 2023.
