TES Compliance provides non-invasive thermal imaging surveys carried out by PCN qualified, BINDT accredited thermographers. Identifying hidden electrical faults before they become serious, with a full written report and thermal images provided on completion.
























Thermal imaging is a non-invasive method of surveying electrical installations without the need to isolate or shut down essential equipment, making it one of the least disruptive forms of electrical safety assessment available. Our PCN qualified thermographers attend your premises at a pre-agreed time, using specialist infrared camera equipment to survey electrical panels, distribution boards, cables and connections throughout your facility. The infrared camera detects heat radiation invisible to the naked eye and displays it as a detailed thermal image, which is then analysed using advanced software to identify hotspots caused by loose connections, overloading, unbalanced phase loading or failing components.
Unlike conventional electrical testing, thermographic scanning can be carried out under normal operating conditions with minimal disruption to your business. Every area surveyed is fully documented and on completion you receive a comprehensive written report containing thermal images, analysis and clear recommendations for any remedial action required.
Our thermographers hold PCN Level 1 or Level 2 qualifications and are accredited by the British Institute of Non-Destructive Testing. Your thermal imaging survey is carried out by engineers qualified and recognised to do so.
Thermographic scanning requires no isolation of equipment and no shutdown of circuits. Your operations continue uninterrupted throughout the entire survey, making it particularly suited to data centres, hospitals, factories and other critical environments.
On completion, you receive a comprehensive electrical thermographic imaging report containing annotated thermal images, fault classifications and clear remedial recommendations, suitable for submission to insurers, facilities managers and health and safety auditors.
TES Compliance provides audited thermal inspection reports both nationwide across the UK and internationally. Whether you require a single site visit or a rolling programme across multiple locations, our thermal imaging surveyors are ready to assist.

Understanding how thermal imaging surveys work, what they identify and why they are an essential part of any planned preventative maintenance programme.
Thermography uses a specialist infrared camera to detect heat radiation and display it as a visible image, which is then analysed using advanced software to provide the thermographer with a detailed insight into issues that cannot be identified with the naked eye. A thermal imaging surveyor can identify a wide range of existing and developing faults across electrical installations, mechanical systems, solar panels, building envelopes and more, all without physical contact or disruption to the equipment being surveyed.
An electrical thermographic imaging survey is one of the most effective tools available for planned preventative maintenance and falls under the category of Non Destructive Testing. Unlike conventional fixed wire testing, thermographic scanning does not require circuits to be isolated or equipment to be shut down, meaning your operations can continue uninterrupted throughout. This makes thermal imaging electrical surveys particularly valuable in environments where downtime is not an option, including data centres, hospitals, factories and other critical facilities.
A thermal inspection of an electrical installation can identify loose connections, overloading, unbalanced phase loading and failing components, highlighting issues that other forms of testing would be unlikely to detect at such an early stage. This allows remedial works to be planned and carried out at a suitable time, before a developing fault becomes a serious or dangerous incident.
Continuous uptime is critical. Thermographic scanning identifies developing faults within electrical panels and connections without any need to isolate equipment or interrupt operations.
Shutting down power in a healthcare environment is rarely an option. Thermal imaging electrical testing allows a full survey of your electrical installation to be carried out safely and without disruption to essential services.
High-demand electrical installations in industrial environments are particularly susceptible to overloading and component failure. A thermal inspection identifies developing issues before they result in costly downtime or safety incidents.
Even in lower-risk environments, thermal imaging electrical surveys can highlight components behaving abnormally under normal load, identifying potential failures that conventional testing would be unlikely to detect.
Regular thermographic scanning is an essential component of any planned preventative maintenance strategy, allowing businesses to address electrical issues at a time of their choosing rather than in response to an emergency.
Thermal imaging camera equipment is highly effective for inspecting solar panel installations, identifying underperforming or failing cells across large arrays quickly and without any physical access to individual panels.

A thermographer is a qualified specialist trained to carry out thermal imaging surveys using infrared camera equipment and advanced analytical software. At TES Compliance our thermographers hold PCN Level 1 or Level 2 qualifications and are accredited by BINDT, the British Institute of Non-Destructive Testing, ensuring every survey is carried out to a professionally recognised and auditable standard.
Thermographic scanning is the process of using a specialist infrared camera to detect heat radiation emitted by electrical components, cables and connections. The camera converts this data into a visible thermal image which is then analysed using advanced software. Hotspots caused by loose connections, overloading, unbalanced phase loading or failing components appear clearly within the image, allowing the thermal imaging surveyor to identify and document faults that would be invisible to the naked eye and undetectable through conventional testing methods.
A fixed wire test such as an EICR requires circuits to be isolated and equipment to be shut down during the inspection. A thermal imaging electrical survey requires no isolation of equipment whatsoever, meaning your operations can continue entirely uninterrupted throughout. This makes thermographic scanning particularly valuable in critical environments where downtime carries significant operational or financial consequences.
There is no single fixed legal requirement governing thermal inspection frequency. However, as part of a planned preventative maintenance programme, an annual thermographic survey is widely recommended for commercial and industrial premises. Higher-risk environments or those with ageing electrical installations may benefit from more frequent surveys. Your thermographer will advise on the most appropriate programme for your specific site and sector.
Yes. TES Compliance provides audited thermal imaging electrical testing reports both nationwide across the UK and internationally. Whether you require a one-off survey of a single site or a scheduled programme across multiple locations, our qualified thermographers are experienced in delivering to the same high standard regardless of location.
Don’t leave compliance to chance. Our fully qualified engineers are ready to assess, certify and protect your property, whether commercial or domestic. With coverage across the entire UK.
