What HYDROLINE SOLUTIONS LIMITED does

Hydroline Solutions Limited is a UK-based civil engineering and pipeline construction contractor founded in 2011 by Neil Elliott in Somerset, England. The company specialises in water sector infrastructure and is positioned to operate in challenging environments including tidal zones, nuclear sites, and protected habitats, serving UK water utilities, infrastructure primes, and nuclear developers through directly employed crews delivering self-executed work rather than subcontracted labour. It is headquartered in Somerton, Somerset, with operations spanning the South West and South East of England.

The company's offering is structured around four service lines: Environmental Work, Pipeline Construction, Civil Engineering, and Early Contractor Involvement (ECI), the last of which engages Hydroline upstream of detailed design. Delivery capability is evidenced by a £27 million Bristol Water pipeline scheme, the Southern Strategic Support Main (2016-2018), and the Corallina Mitigation Project (2017), demonstrating competence across large-diameter water transmission, environmental mitigation in ecologically regulated settings, and complex site delivery. Hydroline holds ISO 9001:2015, SSIP/SMAS, UVDB verification, and GLAA signatory status, and has been recognised with RoSPA Gold, Water Industry Awards, and Green Apple Awards.

Hydroline monetises through contracted civil engineering and pipeline construction work, accessed primarily via two channels: framework alliances, notably the eight2O Partnership Alliance covering Thames Water and other UK water utility programmes, and consortium membership on large capital projects, notably the COMA Consortium delivering civil works at Hinkley Point C for NNB GenCo. Its customer roster includes Tier 1 contractors (Costain, Kier) acting as prime contractors, regional water utilities (Bristol Water, Wessex Water, South West Water, Bournemouth Water, Thames Water), the nuclear developer NNB GenCo, and other infrastructure clients (Wolf Minerals, Parrett IDB). The company is a private limited company (Company #07600223); revenue is not publicly disclosed.
