RGSL was an independent geophysical and geological consultancy established in 1994 by its Managing Director, Dr John M. Reynolds. RGSL was independently recognised as the leading environmental and engineering geophysics consultancy in the UK, and globally as an experienced company within the specialist area of glacial hazard assessment and remediation. RGSL won several small business awards, including the Welsh Small Business Champion award in 2003.

Clients included The World Bank, OECD, UNIDO and other UN agencies, Foreign & Commonwealth Office (FCO), Department for International Development (DfID), international engineering and hydropower consultancies, private companies, local authorities and government agencies (Environment Agency, Countryside Council for Wales). High-profile projects have included the London Gateway Project, Crossrail, the Thames Tideway Project, Woolwich crossing for the Docklands Light Railway, and the Olympics Village, all in London; Abu Dhabi International Airport in the UAE; and major road development schemes (A595 Lillyhall to Parton in Cumbria, New Mersey Crossing).

Due to external circumstances the Management of RGSL were forced to place the company into liquidation on the 28th June 2009, and RGSL ceased trading on 30th June 2009.

Reynolds International Ltd (RIL) is a new company that provides an enhanced range of high-quality services over and beyond those for which RGSL was renowned.



"CEGS have known of Reynolds International Ltd, previously Reynolds Geo-Sciences Ltd, since the mid-1990s and have utilised their services over the years for specific surveying in the former underground coal and iron ore fields of West Cumbria. As a lead consultant, we have used Reynolds International to successfully locate and define both the underground workings and the mine entries that pose a hazard to the built environment, especially shafts in the iron ore workings. Additionally, we have also enrolled on the CPD training courses that are organised by Professor John Reynolds and these provide an invaluable update to our professional skills. We will continue to use Reynolds International as our preferred specialist Geophysical consultancy because of the consistent high professional standards that are applied to every project."

"The British Embassy, Bucharest, has been working with Professor John Reynolds, of Reynolds International Ltd, since 2008 in order to ensure that the Embassy’s earthquake and emergency planning is up to date; and that all staff, dependents and the British community, for which the Embassy has a responsibility, are briefed on the causes, the preparations and the relevant actions in the event of an earthquake. Professors Reynolds’s knowledge, advice and guidance has been invaluable in ensuring that the embassy’s plan is as up to date and in an as workable format as possible. His knowledge is second to none and his guidance is clear concise and in an understandable format."

"The earthquake preparedness training course provided by Professor John M. Reynolds for BAT Romania’ employees during 3 days in February this year was a well designed and tailored course given the high seismic hazard area where Romania is located. The main aim of the course was to provide our employees with necessary information to help them to reduce their own vulnerability at work, in their out-of-work activities and in their family lives. I was very pleased with the results of the training and, most importantly, I have received very positive feedback from participants. I recommend this course for other commercial organizations in Romania or abroad."
