In the UK, current legislation permits scientists to use animals in medical research. The Home Office collects information on animal experiments conducted across Great Britain and publishes an annual report.

On this webpage, we will share the latest statistics on the use of animals in British scientific experiments. We will look at the total number of animal experiments, the species of animals used, the purpose of the experiments, and the severity of suffering they faced.

In British laboratories in 2023, there were:
1.13 million
experiments on live animals to tackle human diseases
248,083
experiments on live animals to test drugs and substances intended for human use
1.21 million
