With a degree in Mining Geology from the Royal School of Mines, Neil started his professional career in the late 1980s in mineral exploration projects, initially working in Canada in the search for platinum-group elements and then subsequently in Botswana with De Beers, engaged in the prospecting and evaluation of primary diamond deposits. Since the early 1990, working for several consulting firms and completing a Master's Degree in Mineral Industry operations in the Mining Department of the University of Leeds, Neil developed expertise in the evaluation and assessment of construction materials for the aggregates, cement and industrial clay sectors and the preparation of development plans to support their efficient and economic extraction. He also gained experience in the coal industry, preparing geological models and mine plans for underground and surface workings.

In 2008 Neil joined Hanson UK (part of the HeidelbergCement Group) as the Geological Services Manager, directing and supporting assessments and reporting of reserves and resources and advising on development planning. In 2010, he took over responsibility for the oversight of geology and land management practices supporting HeidelbergCement's Western European, African and Mediterranean Basin operations.
