For more than two decades, ISG has been providing construction solutions to some of the worlds most successful and enduring businesses, cities and institutions. Our customers trust us to deliver — and our repeat business and numerous industry accolades prove it. 

Yet today’s fast-paced world demands more than a safe pair of hands. Delivering the places of tomorrow requires the ability to think big, collaborate widely and meaningfully, and build in real capacity for change. For this reason, everything we do at ISG, from our work with our customers to our relationships with our own people, is focused on delivering smarter and more resilient places of tomorrow.

Diversity and Inclusion at ISG

Always care
At ISG, one of our core values is to ‘Always Care’. To us, this means always taking pride in the quality of our work and demonstrating respect and care for the wellbeing, health and safety of our customers, our people, and our world. We care deeply about diversity and inclusion in the workplace, and we work hard to make sure our people feel empowered and accepted at ISG. We create environments that foster collaboration at all levels, where everyone can celebrate and share their different perspectives.

We are committed to supporting equal opportunities in employment and make sure that our employment decisions are made on the basis of individual skills, knowledge, abilities, job performance and other appropriate qualifications. We oppose all forms of unlawful or unfair discrimination on the grounds of colour, race, religion, age, national origin, gender identity, sexual orientation, marital status, ancestry, disability or protected veteran status.


ISG’s industry-leading benefits programme is designed with your health and well-being in mind.

More health
Your health and well-being really matters to us. Depending on your role and location you will be able to access all, or a selection, of these benefits: discounted gym membership, private medical insurance, free eye care tests, private GP service and our Cycle to Work scheme.

More recognition
Our Values Awards recognise employees and teams that go the extra mile. Each year we celebrate our successes in each of our business units and then bring together all of these winners to celebrate the ‘Best of the Best’ at ISG’s Global Values Awards Gala Dinner.

More choice
At ISG we are not about uniforms and dress-down days – we trust our people to make the right decision about what to wear and when. We know you’ll remember to be safe and appropriate. Just dress for your day!

More quality time
Your work-life balance really matters to us, so in addition to your competitive holiday allowance we have a You Day to allow you to take an additional day off to celebrate a special event, spend time with your family or just do something that will make your life easier or more enjoyable. We also have a holiday purchase programme so that employees can buy two additional holiday days each year. And finally, we recognise that our people sometimes need time away from work to travel, recharge or volunteer, so once you have worked for ISG for over two years you can apply for an unpaid sabbatical for up to twelve months.

More support for you and your family
We want to support you and your family, so we provide options for childcare vouchers and we offer some of the best maternity, paternity, adoption and family friendly packages in the industry.

More development
At ISG, we believe that you should never stop learning, and so we support you by paying for your professional fees of the most relevant chartered professional body and offering you a wealth of learning and development opportunities through our own Academy.

More weekend
We know everyone at ISG works hard, we finish at 16:00 on a Friday so that you can start your weekend just that little bit earlier. It’s our way of saying thank you for always going the extra mile for our customers and our business. And if you are based in the Middle East, you’ll finish at 16:00 on Thursday to account for your Friday/Saturday weekend.

More giving back
Our payroll giving programme enables you to donate to your chosen charity directly from your gross salary making this an easy and tax efficient way to give something back.

More peace of mind
As well as competitive life assurance, and a contributory pension scheme, we have a number of compassionate policies in place to give you the support you need when it matters the most.

More thank yous
We are incredibly proud of how many of our people choose to stay and build their career with us, our long-service awards are for employees who reach their 10, 20, 25, 30 and 40 year milestones at ISG. We also have a comprehensive reward gateway programme that offers our employees discounts on shopping, restaurants and leisure activities.

More employee referrals
We are always looking for talented, enthusiastic and driven people to join the ISG team but finding them can be challenging. So we have a great employee referral scheme – Scouting for Talent – with up to £3,000 rewards for employees who refer successful candidates. Who better to recommend ISG to a potential candidate, than our own employees!

More advice
We want to make it easy for you to receive quality, timely advice so we provide an employee assistance programme which provides a 24-hour helpline to all employees for confidential advice on all issues from financial concerns, legal advice or feelings of anxiety.

    Average Interview


    I applied in-person. The process took 2 weeks. I interviewed at ISG (London, England) in February 2020.


    Hiring was done through a recruiter. It was clear they were specific on the requirements hence the recruiter looked past the CV. HR manager’s questions are clear and concise, with quick and fair feedback
