What we do

Established in 1976, Nexus operates through three wholly-owned businesses:

TriConnex designs, installs and connects gas, electricity and water networks and, more recently, fibre, on new residential and commercial developments. TriConnex was established in 2011 to take advantage of deregulation in the utilities market with the goal of being recognised as the UK’s leading independent provider of utility connections to new developments. TriConnex’s current areas of operation include the South East, South Midlands and South West of England.


Tamdown provides a range of specialised infrastructure and engineering services to the UK housebuilding and commercial sectors. Services include carrying out earthworks, remedial work, building highways, substructures and basements, creating drainage systems, as well as constructing reinforced concrete frames. The business has a well-established market position having been in operation for over 40 years and currently counts among its customers a number of blue-chip companies and nine of the top ten largest UK housebuilders. Tamdown’s operations are focused on the South East of England and London.


eSmart Networks provides electric vehicle charging infrastructure, connects renewable energy sources and builds smart electrical infrastructure solutions. The business was created in 2017 to respond to the UK’s need for charging infrastructure as the transition from Internal Combustion Engined cars to Electric Vehicles gathers pace. In addition, the business now connects solar, wind and other renewable energy sources to the electricity network and builds on-site high voltage electrical infrastructure to get this renewable energy to the grid.
