Welcome to the Fire Safety Engineering Group (FSEG), pioneer of computational fire engineering, and a world-leader in fire safety science and engineering. Our fire and evacuation research, consultancy, and modelling tools help to solve some of the world's toughest fire, safety and security engineering challenges in the built and urban-scale environments, transportation, and pedestrian environment. Based in London, we have been ranked by the REF as one of the top research groups in the UK for the past 15 years, with 4* (world leading) scores for our two impact case studies in both REF2014 and REF2021. Our contribution to public safety has also been recognised through prestigious awards, including the Queen's Anniversary Prize, the Guardian Research Impact Award, and the SFPE award for the best research project.
