With over 30 years’ experience supporting businesses across the UK, we understand that undetected heat loss can drive up energy costs and reduce building efficiency. That’s why our specialists provide thermal imaging surveys to assess cladded and structural surfaces, identifying insulation gaps, thermal bridges, and energy inefficiencies. Using advanced, non-invasive technology, we help you pinpoint heat loss, optimise energy performance, and plan targeted improvements with confidence.




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:
Undetected gaps in insulation or thermal bridges can drive up heating and cooling costs.
FMSG’s thermal surveys pinpoint these inefficiencies, helping you take action to reduce energy consumption, lower operational costs, and improve building performance. By providing a clear visual map of heat loss, we enable fast, informed decision-making for insulation upgrades.
Heat loss can indicate moisture ingress or deteriorating materials that may lead to long-term damage.
Thermal imaging allows early detection of these risks, helping you prioritise repairs and protect your building fabric before costly problems arise. Early intervention reduces disruption, repair costs, and potential downtime for operations.
Poor insulation can impact comfort, energy bills, and environmental targets.
Our surveys highlight areas where insulation is underperforming, enabling targeted improvements that enhance thermal efficiency and occupant comfort. This ensures every improvement delivers measurable energy savings and long-term efficiency gains.
Inefficient buildings contribute to higher carbon emissions and operational costs.
By identifying and addressing heat loss, our thermal surveys support energy-efficient upgrades, helping you meet sustainability targets while reducing environmental impact. This proactive approach also enhances your building’s market value and compliance with environmental standards.
