Henry Holdaway - Babbage

Babbage worked with Decom to install seven kilometres of underground 33KV cable, linking the Mataura Valley Milk Project back to the Gore Sub-station. As well as the installation of the on-site 11KV ring and associated RMU’s and Transformers.  We found Decom to be dependable and professional. Buying into our milestones and striving to complete the job on-time. They were a pleasure to work alongside, with a team of hardworking diligent staff that demonstrated good leadership at multiple levels.

Through good communication and trust we have built a strong working relationship that we can rely on moving forward.
