Company overview

Costain is one of the UK’s leading engineering solutions providers, delivering integrated consulting, project delivery and operations and maintenance services to major blue-chip customers in targeted market sectors.

Innovation is at the heart of the business and enables us to provide the solutions our customers need.

Career development


Costain recruits up to 20 apprentices annually across a whole range of disciplines. There are also many more opportunities through our supply chain partners. The main intakes are in the summer for a start in college in September.

Apprentices normally work on a day-release basis, attending college one day per week and working for the other four days. They complete a NVQ level 3 in a relevant discipline. Costain supports apprentices via mentoring and internal development.


Costain works with schools linked with our projects across the UK. Please contact the project directly if you would like a presentation at your school.

We offer work experience on our projects. These placements may result in an Apprenticeship or sponsorship on our ‘Third Way’ earn-while-you-learn or full-time at university.

Undergraduates & graduates

Costain recruits between 35 and 50 graduates each year, and of these up to half are sponsored or offered work experience during their degree.

There are many reasons to choose Costain if you are considering going to university full-time or part-time, or are looking for a role when you graduate:

A career in a well-recognised organisation, working alongside high calibre colleagues
Work opportunities in a diverse range of sectors and locations
The opportunity for sponsorship
An accredited further-learning scheme that enables a BEng graduate to save a year’s worth of tuition fees
Our professional development is highly valued, fast tracking your route to chartership in under five years
We offer a highly competitive salary and benefits package

Experienced candidates

We recognise that successful teams need people who have different skills and approaches.

We’re looking for highly technical people who understand the importance of process in delivering highly complex solutions for our customers. We’re also looking for people who can innovate, and who don’t want tomorrow to be the same as today.

We need leaders who can inspire others to deliver projects safely, on time and for outstanding value. Whatever the skills and personality, Costain people have a common approach to their work: a duty of care to the stakeholders we serve and affect.

Costain is open-minded, innovative and welcomes diversity.
