Chris is a graduate chemist with in excess of 30 years’ experience in water treatment and water hygiene.


His experience in the water treatment industry started as a graduate trainee for a major water treatment company and led to a key account management role, specialising in water treatment for the steel and petrochemical industries. With the commencement of interest in legionellosis in the 1980s, Chris formed Brocol Consultants Limited in 1989, which specialised in industrial and domestic system risk assessment, and cooling system cleaning and disinfection works, across the UK.   


In 2006 Brocol was acquired by South Staffordshire PLc and was integrated into IWS Ltd. Chris became a Director of IWS in 2006 and Managing Director in 2014. Chris retired from IWS in 2017 and formed InSource Consulting Ltd, and alongside his specialist risk assessment work, Chris now appears as a guest speaker at Legionella events, and provides consultancy support in policy writing, contractor auditing and tender specification.
