NC3Rs: National Centre for the Replacement Refinement & Reduction of Animals in Research
Pioneering better science

Who we are

The NC3Rs is a UK-based scientific organisation that works nationally and internationally with the research community to replace, refine and reduce the use of animals in research and testing.

We collaborate with scientists and organisations from across the life sciences sector, nationally and internationally, including universities, the pharmaceutical, chemical and consumer products industries, other research funders, and regulatory authorities.

We support the commitment of the scientific community to the 3Rs by funding research and early career development, supporting open innovation and the commercialisation of 3Rs technologies, and stimulating changes in policy, regulations and practice.
