Chris co-founded OnGen in 2014.

Chris is a chartered accountant, who trained with KPMG Peat Marwick before moving into senior finance positions with a range of technology companies (mobile telephony and interactive TV) from 2000.

Chris’ experience in the energy sector started in 2006 when he became a founding director and shareholder at Spark Energy Ltd (Sunday Times Fast Track 2014 – 23rd).

After leaving Spark Energy, Chris started his own consultancy business, Clearer Energy Ltd, advising a wide range of organisations on entry into the UK energy supply market, including a number of listed organisations, international energy supply companies, local authorities, renewable generators and housing associations.

Clearer Energy placed an emphasis on assisting community energy schemes to use local energy generation capacity from a range of technologies from wind to solar PV to reduce levels of fuel poverty.

Andrew is a co-founder and Director of OnGen.

Andrew is an experienced practitioner with over 20 years working in the environment and energy consulting sector.

He has held several senior roles at large corporate consultancy practices and is currently Operations Director of a fast-growing energy and environmental consultancy practice, ITPEnergised.

Andrew specialises in advising blue-chip companies on the implementation of sustainable strategies into their business, understanding the impacts of climate change and highlighting the economic opportunities that can be delivered through resource and energy efficiency.

His experience includes significant work in Russia, Africa, Asia and mainland Europe, with a wide range of sectors, including oil and gas, food and drink, transport, construction and infrastructure, energy generation, manufacturing and finance.

Over the past 5 years, Andrew has worked closely with the renewable energy industry providing feasibility assessments, development support and technical due diligence on a range of technologies and developments. Through this activity, it became apparent that tools like OnEfficiency, OnGen Expert and OnSupply would provide ways to support and assist organisations who have an interest in carbon neutral energy but lack the technical know-how.
