The move follows the imminent departure of former chief executive Lee Powell to Henry Boot Construction where he takes-up his new role in January.
Jones has been promoted from Divisional Managing Director for the Midlands, where he has played a fundamental role in the establishment of GMI’s presence in the region.
He will be transitioning into the group role during the last quarter of this year and will lead the business alongside new Group Commercial Director Richard Davies who was previously Commercial Director of the Midlands region.
Jones said, “I am absolutely delighted to be leading GMI in achieving its strategic objectives, alongside continuing to place our people at the forefront of the group. We have developed a fantastic business working with some outstanding clients across our core regions.
“Our contribution to the development of the built environment in Yorkshire, the North East, North West and the Midlands continues to be an essential part of the UK economy, through the creation of employment opportunities, new homes and business premises.
“This is a huge achievement that I’m incredibly proud of and I look forward to working closely with colleagues and clients across our key regions.”
Jarrod Best, GMI chairman said, “This is an incredibly well-deserved appointment. Gareth has done a fantastic job delivering for multiple regions and is an asset to the team.
“Gareth’s dedication and strategic approach to growth will drive the profitable consolidation we are focusing on and will ensure our projects are delivered to a high standard. A huge congratulations to Gareth and we look forward to the new era of GMI”.
