With over 30 years’ experience supporting businesses across the UK, we understand that no two electrical systems or the demands placed on them are the same. That’s why we help organisations of all sizes modernise, expand, and futureproof their electrical infrastructure. From LV upgrades and switchgear replacements to substation builds and high-voltage installations, our in-house engineers deliver fully compliant solutions that increase capacity, reduce risk, and ensure your infrastructure keeps pace with operational growth.
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:
Ageing electrical infrastructure can pose safety risks, cause recurring faults and unplanned downtime.
FMSG delivers compliant infrastructure upgrades that meet the latest safety regulations and performance standards. From switchgear replacements to distribution board upgrades, we modernise your electrical infrastructure to ensure safe, stable, and efficient power distribution across your site.
Outdated electrical systems often require frequent inspections, temporary fixes, and struggle to meet evolving compliance standards.
FMSG delivers strategic electrical upgrades that reduce the burden of ongoing maintenance while aligning your infrastructure with current regulations and EPC targets. By replacing ageing assets with modern, certified components, we help you cut servicing costs, simplify audits, and maintain consistent compliance with less disruption.
Without real-time visibility, faults and inefficiencies often go unnoticed until they cause disruption or downtime.
FMSG integrates monitoring technologies into your electrical infrastructure—enabling live performance tracking, automated alerts, and data-driven maintenance planning. This proactive approach helps you identify issues before they escalate, reduce unplanned downtime, and extend the lifespan of critical systems across your estate.
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.
