An often-overlooked area of the building envelope is thermal bridging, which many commonly mistake as a purely technical design issue, but the reality is very different. It poses risks to energy performance, compliance, building safety, and occupant health across a wide range of properties. For owners, duty holders, and managers, recognising and mitigating thermal bridging is essential to creating buildings that are safe, sustainable, and future-proof.
AT A GLANCE
- Discover why thermal bridging is a critical safety and compliance issue, not just an energy concern.
- Learn where thermal bridges most commonly occur in UK buildings and what warning signs to look out for.
- Explore how technical surveys, infrared thermography, and digital modelling help identify hidden risks.
- Gain practical advice for building owners, duty holders, and managers on when and how to act.
Thermal bridging is not only an energy-efficiency concern. Poor thermal detailing can compromise compliance with the energy performance and moisture-control requirements of the Building Regulations, while increasing the risk of condensation, mould and deterioration. Where remediation forms part of regulated building work, particularly within a higher-risk building, the design and delivery process must also be managed and evidenced in accordance with applicable Building Safety Act responsibilities.
Adam: A question that many of our clients ask us. We start with knowledge and evidence. Using infrared thermography, digital modelling, and intrusive surveys where needed, we identify where heat loss occurs and design solutions to address it.
Our strength lies in our integrated business model. We do not stop at the survey or condition report. Our façade design expertise, engineering knowledge and delivery teams provide clients with a comprehensive pathway from initial investigation through to a safe, compliant and cost-effective solution.
This approach can be seen at Ketley House, where U-value calculations and condensation checks helped confirm that the replacement façade system would meet, and wherever possible exceed, the applicable Building Regulations.
It’s about giving clients peace of mind and mitigating compliance and schedule risks, including thermal, environmental, or safety-related issues, within a single coordinated partner and solution.
“Thermal bridging is more than an energy problem; it’s a safety and compliance issue that can affect people’s health, comfort, and trust in the buildings they live and work in and the spaces they interact with.”

Director, London South Business Hub, Starfish Construction
Adam: Addressing thermal bridging isn’t just about fixing cold spots; it’s about future-proofing buildings. By reducing uncontrolled heat loss, you’re lowering operational energy demand, which directly supports the UK’s net zero targets. At Starfish Construction, we often integrate thermal remediation works with broader sustainability upgrades — such as façade insulation improvements, energy-efficient roofing, or even preparing for renewable technologies.
For building owners, this means that every pound invested in remediation delivers multiple returns: safer buildings, lower operating costs, regulatory compliance, and a stronger sustainability profile, aligning with environmental, social and governance objectives for property owners.
Many thanks to Adam Denton-Beaumont for sharing his expertise on this critical subject.
At Starfish Construction, we deliver safe, compliant and sustainable building solutions. From thermal surveys and technical reporting through to façade remediation and project management and roofing redesign, our integrated divisions and experienced people help clients reduce risk, improve performance and create long-lasting value.
