Our Team

Jonathan Gardiner

Managing Director

In April 2021, Jonathan took over as Managing Director at Total Utilities. Jonathan is extremely excited to be leading our growing team and delivering new and sustainable service offerings to our clients.

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.

Richard Gardiner

Sales Director

Richard founded Total Utilities Management Group in 1999 and passed the Managing Director baton onto his son Jonathan in April 2021. Richard who is passionate about sales, now leads the wider sales team. Richard’s career has seen him working in the manufacturing, power generation and gas industry across 3 countries from the UK, South Africa and now New Zealand.

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


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.

Chris Hargreaves


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 was a Certified Measurement and Verification Professional (CMVP) from 2016-2019.

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.
