Pioneering Better Science


The NC3Rs is the UK's national organisation which leads the discovery and application of new technologies and approaches to replace, reduce and refine the use of animals for scientific purposes (the 3Rs).

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 fund 3Rs research, training and career development, support open innovation and commercialisation of 3Rs technologies, and stimulate changes in policy, regulations and practice relating to the use of animals.

Keep in touch

Our open innovation programme supports the development of marketable products and improved business processes with 3Rs benefits.
