Eight jobs are at risk at the Islands Energy Group across Guernsey and the Isle of Man.
The company, formerly Guernsey Gas, will soon begin a formal consultation process with the employees affected.
It says a plan to become net carbon zero has changed some roles, although it's still hiring staff in other areas.
"These changes have resulted in eight roles that no longer align with our new structure and a number of colleagues are being placed ‘at risk’ of redundancy.
Reviewing our organisational structure is part of our work to ensure that we can provide excellent service to our customers.
Re-investing in roles across the business that better align to our operating model is key and we will continue to do this.”
“There is no one single reason for our restructure. Rather it is part of our strategy to develop and evolve the business into a shape that is fit-for-purpose both now and in the future.”- CEO Jo Cox.
