He joined the energy network business in September 2023 as chief financial officer and will take over from Mark Wild who is leaving to run the high-speed rail project HS2.

Mr Kilonback is a highly respected leader with extensive experience in safety orientated companies which are part of the UK’s critical national infrastructure. He was previously the CFO of Transport for London for five years.

He has a strong track record in the public and private sectors of steering complex businesses through challenging periods and delivering successful outcomes.

Mr Kilonback’s priorities will include SGN’s relentless focus on safety, driving efficiency and looking after the most vulnerable customers, while also leading the business through the upcoming GD3 price control process.

SGN chair Becky Lumlock said: “Simon is a talented and experienced leader who has already made a huge impact at SGN, rightly prioritising investment in our frontline operations to ensure we continue to keep all our customers safe and warm. He is a driving force in creating the conditions for future success and ensuring our network can play a key role in the resilient national energy system that will be required to make net zero possible.

“On behalf of the board, I would like to thank Mark Wild for his service and achievements during his time with SGN and wish him well for the future.”

Mr Kilonback said: “I’m delighted to have the opportunity to lead SGN which is such a vital part of our national energy infrastructure. We have great people and an exciting future as we build one of the UK’s most respected engineering and asset management companies.

“We will continue to keep our communities safe and warm, serving millions of households and businesses as well as playing our part in a fair and affordable energy transition.” 

Mr Kilonback is expected to take up the role of CEO later in the calendar year.
