Who we are

Built on delivery

TPL Infrastructure Ltd is a mechanical and electrical infrastructure contractor. We take on the installations other contractors find difficult: live network environments, tight energisation windows, and projects where the mechanical and electrical scopes have to land together.

Our teams are trained, certified, and used to working to utility and client specifications. We plan the work properly, communicate early when something changes, and hand over installations that are tested, documented, and ready to energise.
