Costain is welcoming a record number of apprentices in 2026 to support its delivery of critical national infrastructure across the UK.

The infrastructure solutions company is onboarding 50 apprentices this year, doubling last year’s intake in response to growth in its volume of long-term infrastructure projects and commitment to building a growing pipeline of talent.

The hiring activity is taking place across all of Costain’s infrastructure sectors, which include road, rail, integrated transport, energy, water, and defence and nuclear energy, and in a variety of disciplines, such as civil engineering, electrical and mechanical engineering, quantity surveying, finance and project management.

Costain offers all levels of apprenticeship in the UK, including degree-level, and each apprentice will ‘earn and learn’, completing a programme of training which lasts from 12–60 months, depending on the level of study.

Costain also recruits for graduates, internships and university placements across its sectors and has a Graduates and Apprentices (GRaAPS) network to support professional development.

Costain’s apprentices will join some of the UK’s most important infrastructure projects, including:

delivering the London tunnels section of HS2 as part of the Skanska Costain Strabag joint venture strategic water infrastructure through long-term AMP8 frameworks with Southern Water and United Utilities

critical utilities infrastructure upgrades for Sellafield.

More details on Costain’s planned early careers and apprenticeship intake for 2027 and how to apply will be released in November.

Catherine Duffy, Chief People and Sustainability Officer at Costain, said:

“I’m extremely proud to be welcoming a record number of apprentices into Costain. The industry requires more skilled workers than ever to deliver critical infrastructure for a more prosperous, resilient and decarbonised UK, which makes it a hugely exciting time to enter the sector.

“Our apprentice programme underscores our commitment to offering vocational routes into employment. It is designed to help apprentices earn while they learn and gain qualifications with real-world experience to help them build a meaningful, long-term career.”
