With over 30 years’ experience supporting businesses across the UK, we understand that no two energy strategies or their demands on infrastructure are the same. That’s why we work with organisations of all sizes to design efficient, future-proofed grid connections while sourcing the most competitive and sustainable energy contracts. From initial load assessments and substation design to DNO liaison and renewable procurement, our experts optimise your grid infrastructure and energy spend—ensuring resilience, compliance, and long-term cost control.










At FMSG, we’ve made a conscious decision to focus our services within select UK counties—not to limit our reach, but to raise our standards. By operating within a defined region, we’re able to maintain exceptional service standards, respond faster, support our teams more effectively, and build stronger, longer-lasting relationships with our clients. It’s not about covering more ground—it’s about delivering more value where it matters most.
Over the last three decades we have become experts in a variety of sectors, some of our specialisms include:
Meeting regulatory standards and safety requirements is critical for all electrical infrastructure, yet navigating legacy systems can be challenging.
FMSG designs grid infrastructure with compliance and safety at the core, ensuring your systems meet all relevant standards and legislation. Our expertise minimise risk, protect your people and assets, and gives you peace of mind that your electrical infrastructure operates safely and reliably.
Energy needs evolve fast, and inflexible infrastructure can quickly become a bottleneck to growth and innovation.
We help you build grid systems that scale alongside your business ambitions. By anticipating future power demands and integrating flexible designs, FMSG ensures your infrastructure supports expansion, new technologies, and evolving operational needs—future-proofing your energy supply.
Long waiting times and restrictive grid connections can stall your projects and increase costs.
FMSG works proactively to navigate these challenges by designing smart infrastructure that maximises your existing capacity. We offer practical solutions that reduce dependency on lengthy DNO upgrades—helping your site stay operational and your projects on schedule.
Dealing with Distribution Network Operators can be complex and time-consuming, often leading to unexpected costs.
Our team takes the hassle out of DNO interactions, managing communications and technical requirements on your behalf. We also explore Independent Distribution Network Operator (IDNO) asset valuations to identify potential cost savings and flexible ownership models—helping you optimise expenditure while maintaining robust, compliant networks.
