27 October 2023

The Board of Xoserve is delighted to announce that it has appointed Steve Brittan as the new CEO of Xoserve. Having served as interim CEO, the Board has seen strong evidence that Steve has demonstrated the values and executive experience that the company needs as it moves forward to meet the challenges of the changes in the energy markets over the coming years.

The Board also were impressed with Steve’s extensive technical background which gives him a deep understanding of the information systems that Xoserve delivers as the UK’s Central Data Services provider for the gas industry.
