“CSD Technical Services delivered the water, and gastight sealing works to a high standard across our control room and DNO substation. Their support contributed effectively to our wider climate action plan, including the installation of a new solar farm and battery storage system. We were very satisfied with the work and will be considering CSD for future projects.”
