Our Team

Richard Gardiner

Managing Director

Richard founded Total Utilities Management Group in 1999 and is head of sales and marketing. A former Managing Director in the manufacturing sector, Richard uses the technical experience gained working in the power generation equipment and gases industries in the UK, South Africa and NZ to help him lead a team of specialist consultants.

Gardiner by name and gardener by nature. Richard is also a fanatical supporter of Ipswich Town FC and his interests range from genealogy to environmental issues and his longstanding project (still at the conceptual stage!) to write a novel.

David Spratt

Director, Strategy and Transformation

David uses the experience he gained through 30 years of senior ICT roles to guide clients through a measured decision-making process, building strategy and ensuring customers make the best technology investments for their business.

David volunteered as a sports coach for over thirty years but has now retired to the couch where he spends his Saturday evenings yelling at the TV about technique, tactics and team selections.

David also serves as a trustee for the Counties Power Consumer Trust.

Mike Ette


Mike has over 25 years of experience in the ICT industry with specific expertise in Telephony, Unified Communications, Data Networking and Managed Services. Understanding customer requirements, with his pragmatic approach, ensures Total Utilities’ customers achieve outcomes that best reflect their business needs.

When not being a taxi service for his two sons, Mike spends the small amount of his available spare time, indulging in his love for V8 powered vehicles, including a 1968 Firebird and a highly modified 1962 EJ Holden project.

Jonathan Gardiner


As General Manager at Total Utilities, Jonathan is extremely versatile in delivering high quality insights and analytics spanning ICT, Natural Gas and Waste.

Jonathan is a keen hiker and loves getting into the great outdoors. When he can’t get outdoors, he reads or watches anything he can find on science, politics and history. He captains social cricket and football teams, and believes these are to blame for his alarming onset of grey hair. He loves cricket, football and soccer although his aptitude for all three falls well short of his passion.

Chris Hargreaves

Director, Energy Markets and Analytics

Chris joined Total Utilities in 2007 and sets a high standard for the analytics team. As a creative problem solver he employs an investigative approach to analysis ensuring that outcomes are measured and quantifiable.

Chris spends weekends inventing things in his workshop on the farm and enjoying the outdoors. He is also the co-captain of the office cricket commentary box and along with Jonathan is a long-time member of the Natural Disasters indoor cricket team.
