About Harwell Campus
Harwell Campus is a 700-acre science and innovation campus in southern Oxfordshire, 2 miles outside Didcot and 15 miles south of Oxford. More than 7,500 scientists, engineers and innovators work across 250+ organisations, with £3bn of scientific infrastructure on site. The campus clusters around four themes: space, health and life sciences, energy and environment, and quantum computing and data.
Originally RAF Harwell (1935), the site became the UK's Atomic Energy Research Establishment after the Second World War — where the world's first transistorised computer (CADET, 1953) and first experimental fast reactor (ZEPHYR, 1954) were built. It transitioned to a science and business campus from 1996 and is now operated jointly by UKAEA and STFC.
For people considering a move to Oxfordshire, Harwell is a major reason to look beyond Oxford city. It offers globally significant work within reach of villages, market towns, countryside and fast rail links to London and Oxford.
