Our services

Delivering places that help people and businesses thrive.

Complete certainty is an ambitious target, and so we focus on three key areas of our service to ensure we reach it. Firstly, we constantly strive to drive down project risk. At the same time, we drive performance upwards, integrating methods, data and technology to the benefit of project efficiency and performance. Finally, we never take our eyes off the customer journey, striving to provide you with certainty not just at completion, but at every step along the way.

Fit out

When it comes to professional and high-quality fit out services, we are unparalleled. Our track record reveals broader experience across a wide range of sectors, geographies and projects than any other provider in the market. From major office fit outs to large-scale global retail rollout programmes, from 'day-two' works to ATM installations, for decades we have delivered environments vital to our clients’ business operations and highly responsive to their evolving industries.


When it comes to refurbishing or alteration and addition works, ISG is one of the most respected and active specialist contractors. We have delivered numerous complex refurbishments, often in occupied buildings, and have a strong track record in transforming tired and unproductive real estate into vibrant and inviting spaces, always meeting both the developer and tenants’ needs.


We have the extensive, multi-disciplinary expertise and specialised skills to deliver highly-engineered environments in the technology, science and health sectors, but we also have a dedicated Technology Solutions team for clients who want to challenge the traditional technology delivery model. Our differentiated technology and engineering expertise reflects our commitment to smarter solutions for our customers.
