Utilities has become a specialist sector within Sienna and we are proud to have been working alongside major utility companies since our formation. We have worked with organisations such as SSEN, SGN and ESM Power to deliver brand new substations and also to refurbish or extend existing substations, across the South of England.

With this in mind, we decided to expand our geographical area and target a new client, Western Power Distribution (WPD). After an in-depth pre-qualification and tendering period we successfully secured a place upon their Midlands Framework, and have now secured our first project to deliver Network Improvements to Kirton 33kV Substation. Works are due to start on site shortly.
