Why choose nexos?

Fully Integrated EPC Expertise

Unlike traditional service providers that separate engineering and construction, we bring these disciplines under one roof, ensuring a seamless transition from design to execution. Our team anticipates constructability challenges early, leading to smoother, faster, and more cost-effective project delivery.

Proven Track Record in Onshore Energy

With a history rooted in both traditional and emerging energy sectors, we have successfully delivered projects across critical industrial hubs such as the Humber Cluster, Teesside, and the Midlands. Our work spans industrial decarbonisation, advanced manufacturing, and energy transformation initiatives.

Modular + Scalable Solutions

Through our in-house fabrication and modularisation expertise, we reduce site-based construction risk, enhance quality control, and enable faster installation with minimal disruption. Our modular approach is ideal for hydrogen plants, battery storage, and process intensification projects.

Safety, Compliance + Sustainability

At nexos, we prioritise safety, environmental responsibility, and compliance with the highest industry standards. Our teams are well-versed in ATEX, COMAH, and hazardous area regulations, ensuring projects meet the most rigorous requirements.

Digitally enabled

Our in-house team of developers have developed a proprietary digital ecosystem (Slingshot), which seamlessly integrates everything we do, supporting our teams across the full lifecycle of a project. Our customers can trust their project is in safe hands because they can see it in real time.

D2Zero Track, our proprietary carbon intensity tracking system based on trusted, immutable blockchain technology, supports our customers in meeting their sustainability goals.
