Why Choose APT for your Thermal Imaging Survey? For starters, we have extensive experience in infrared inspections across various sectors, including engineering, construction, maintenance, and management. Our services span the entire UK, and our professional thermography engineers are qualified according to BS EN 13187. Trained to Level 3, we surpass the requirements set by BREEAM, ensuring high standards in our work. Additionally, we continually update our knowledge and techniques to stay at the forefront of thermal imaging technology.
Another critical consideration is the quality of the thermal imaging cameras we use. Our thermal imaging equipment ranks among the best and most accurate on the market, ensuring we detect faults that other companies may overlook. While many firms utilise thermal cameras priced at £2,000 to £3,000, our equipment ranges from £10,000 to £30,000. This investment means our cameras provide much higher resolution and superior sensitivity, allowing for more precise analysis. Moreover, as technology evolves, we regularly assess and upgrade our tools to maintain the highest standards in thermal imaging.

Here is a quick breakdown of our premium service:
We also take pride in our commitment to sustainability. By helping clients identify and resolve inefficiencies, we contribute to reduced energy consumption and environmental impact. This aligns with our core values and resonates with an increasing number of clients who prioritise eco-friendly practices.
Customer satisfaction is our top priority, and we have a track record of positive feedback from our clients. They appreciate our thoroughness, professionalism, and the actionable insights we provide. Many of our clients return for future services, reflecting the trust we have built over the years.
Furthermore, we understand the importance of clear communication throughout the process. Our team ensures that clients are kept informed at every stage, providing updates during the survey and explaining the findings in an accessible manner. We believe that transparency is vital in building trust and ensuring satisfaction.
Our experience allows us to advise clients on how to use the results of our surveys effectively. We provide recommendations that not only address immediate problems but also contribute to long-term energy efficiency and cost savings. By identifying issues such as air leaks or moisture intrusion early, we help clients mitigate future damages and reduce operational costs.
In addition, we regularly participate in training and professional development to keep our team updated on the latest advancements in thermal imaging technology. This dedication to ongoing education ensures we are equipped to handle a wide range of scenarios, from identifying insulation issues in residential buildings to diagnosing complex industrial systems. We pride ourselves on being at the cutting edge of the industry, which directly benefits our clients.
Our commitment to quality extends beyond equipment; it encompasses our methodology. We follow a structured process for every Thermal Imaging Survey, beginning with a detailed consultation to understand the specific needs of our clients. This allows us to tailor our approach, ensuring we focus on the areas most relevant to each project. We also conduct thorough site assessments prior to the survey to identify potential challenges and optimise our inspection routes. This proactive approach helps us maximise efficiency and deliver comprehensive results.

Identifying Hidden Issues Without Direct Access
Ultimately, our goal is to provide a comprehensive service that encompasses not only the detection of problems but also the tools and knowledge necessary for effective resolution. We believe that this holistic approach sets us apart in the industry.
Our thorough reports not only detail identified issues but also provide guidance on monitoring and maintenance strategies. We aim to empower our clients with the knowledge they need to maintain their properties effectively. Our insights enable them to make informed decisions regarding repairs and improvements.
In addition to identifying existing problems, thermal imaging plays a crucial role in preventative maintenance. By regularly conducting surveys, clients can monitor their properties and catch potential issues before they escalate into costly repairs. This proactive approach not only saves money but also extends the lifespan of buildings and equipment.
Moreover, the ability to identify issues without direct access means we can carry out inspections with minimal disruption to the operations of businesses and residents alike. Whether we are working in schools, hospitals, or industrial settings, our non-invasive techniques ensure that we respect the environment we are working in, promoting a hassle-free experience for our clients.

One of the significant advantages of thermal imaging is its ability to identify hidden defects that are not visible to the naked eye. Thermal cameras can detect temperature differences that indicate problems such as insulation deficiencies, moisture intrusion, and electrical faults. Our surveyors can assess these issues without having to access confined or elevated spaces, minimising the risk of accidents, such as falls from height.
In conclusion, choosing APT for your Thermal Imaging Survey means opting for quality, expertise, and a commitment to customer satisfaction. With our advanced technology, experienced team, and dedication to ongoing improvement, we are confident in our ability to meet and exceed your expectations.
As technology advances, the applications of thermal imaging continue to expand. From identifying energy inefficiencies in residential properties to evaluating the condition of electrical systems in commercial buildings, the versatility of thermal imaging makes it an invaluable tool across multiple sectors.
Thermal imaging surveys are not just about identifying problems; they are also about understanding the broader context. We provide insights into how the identified issues relate to overall building performance and energy efficiency. This analysis helps clients prioritise repairs and improvements that will have the most significant impact on their operational efficiency and comfort.
