We've had a UK presence for over 70 years, and are committed to working with the NHS and other healthcare organisations across the system, developing solutions to improve the delivery of care and to support the best possible patient outcomes.
In 2023, we spent over £268 million supporting research and development carried out in the UK and contributed to 104 collaborations during 2025, with universities, pharmaceutical companies, industries and others. Through collaborations with scientists, academics and clinicians, sharing knowledge, skills and expertise we aim to improve the health and lives of people in the UK and around the world. During 2025, we had 55 clinical trials on-going in the UK, across 73 UK sites.
The UK is an important location for Pfizer, with around 1,900 colleagues in five locations working across our commercial business and research and development.
