Information on the number of animals used for scientific procedures under the Animals (Scientific Procedures) Act 1986 are reported annually to the UK Home Office. They form part of the national statistics which the Home Office publishes each year.

St George’s has additionally published the species and number of each species used at the university on our website since 2013, and will continue to disclose the five most recent reporting years’ data in the future. From 2019 onwards, we will aim to provide a more detailed degree of information in our reports. This is occasionally the basis of freedom of information (FOI) requests, to which the university publishes responses online.
