The Home Office reported that experimental procedures accounted for half of all procedures (1.80 million) carried out on animals in 2018. It added that 56% of these experimental procedures were for the purpose of basic research, most commonly focusing on the immune system, the nervous system and cancer. In this area, 60% of procedures used mice, 17% used fish and 9% used rats.

The remaining procedures (1.72 million) were categorised as procedures for the creation and breeding of genetically altered (GA) animals.
