Our People

ISC has emerged as a leading force within the industry, owing its success to the unwavering commitment of enabling works, earthworks and civil engineering projects across the UK.

People are at the heart of everything we do.

Our organisation is deeply rooted in the collective spirit and values our dedicated staff uphold. Our team exudes a can-do attitude, demonstrating care, inspiration, and a drive to achieve excellence every day, continually enhancing their skills and knowledge.

We’re dedicated to fostering the growth of our people, ensuring our staff continue to develop their skills throughout their time at ISC and the GRS Group. Today, our primary strategic objective at ISC is to stand as the unrivalled leader in nurturing our talent.

By ensuring that we have the right individuals equipped with the necessary knowledge, skills, and motivation, we seamlessly transition to our second strategic priority: becoming the premier name in customer experience. Together, our quest to excel in people and service positions us to fulfil our third strategic priority—achieving top status in the markets we serve.

In line with our vision, in 2017 GRS founded the GRS Academy, solely dedicated to delivering robust learning and development programs designed to empower ISC and GRS employees to thrive. The GRS Academy has had phenomenal success and has grown to become an accredited provider of development programmes across a range of levels and business functions.

We believe in nurturing talent, fostering a culture of collaboration, and celebrating achievements. When you join ISC, you’re not just taking a job; you’re becoming part of a legacy that’s built on people and the pursuit of excellence.

Our people are the driving force behind our success, which is why they are rooted in our company vision, mission and purpose.


Our five core values

People are at the heart of everything we do.

Here at GRS we’re proud of our long-standing reputation for the positive way we work with our customers, suppliers and business partners. This is conveyed through our company tagline “We Go Beyond”.

And to really capture the essence of what GRS is all about, we have set out five core values which define who we are and how we work. These are:


People are at the heart of everything we do. We all look out for one another, and in doing so help to create a happy, rewarding, safe and healthy workplace. Everyone is included, respected and valued.


Together we contribute to something exceptional, building strong working relationships to achieve common goals. We inspire and challenge each other to go beyond, showing leadership, responsibility and trust.


We nurture the strengths of every person so they can do their best. We create opportunities for learning and development, supporting everyone to achieve their goals and realise their ambitions.

Can Do

We work with positivity, passion and flair, seeing obstacles as challenges to overcome. We’re agile enough to adapt when things change, yet determined enough to go beyond to make things happen.


We’re continually improving to ensure we’re number one in our chosen markets, in customer service and in people development. Each person contributes to, and shares in, our undisputed success.

GRS has grown to become largest business of its kind in the country thanks to the dedication of its 800-strong workforce who are known for ‘going beyond’ for colleagues and customers alike.

Our business is founded on the spirit and collective values of those who work in the organisation. Our people have a can-do attitude, they care, they inspire each other and they are driven by a desire to excel every day, learning and improving as they go.

Our approach has evolved into a passion for developing our people development, something that has become increasingly important for GRS. Today the first of our three GRS strategic priorities is to become #1 for people.

Having good people with the right knowledge, skills and motivation enables us to achieve our second strategic priority, to be #1 in customer experience. Together, being number one in people and number one in service will allow us to realise our third strategic priority which is to be #1 in the markets we operate in.

In pursuit of our vision, in 2017 we founded the GRS Academy, dedicated to delivering learning and development programmes that give GRS employees the opportunity grow. The GRS Academy has had phenomenal success and has grown to become an accredited provider of development programmes across a range of levels and business functions.
