Delivery you can trust, documented end to end
Western Power authorisations, held personally
Our senior team holds Western Power authorisations personally, meeting your vendor compliance requirements from the outset.

Responsive and direct at every stage
When something goes wrong on site, you are talking to the person who can fix it, which keeps small problems from becoming delays.
We engaged Alltech Power Solutions to complete Transformer Oil Filtration on 2x units, one located underground and one on the surface. Armed with their expert knowledge in the field of high voltage electrical systems, they completed this work to a high standard and in good time. Their can-do attitude and willingness to get in and get the job done safely and efficiently is to be commended and we look forward to working with them again in the future.
