At Thermal Imaging Survey, we provide expert infrared inspections that help property owners and businesses across the UK detect hidden faults quickly, safely, and without disruption.

Using high-resolution thermal imaging equipment, we identify issues such as heat loss, water ingress, electrical faults, pipework failures, and insulation gaps, before they cause serious damage.

Whether you’re investigating a damp patch, checking roof performance, or carrying out a preventative maintenance check, our thermal imaging surveyors deliver clear insights with fully certified reports.

How Is a Thermal Imaging Survey Used for Properties?

In properties, thermal imaging surveys are used to assess heat retention, identify insulation problems, track down moisture intrusion, or spot faults in underfloor heating, pipework, or electrical circuits.

The survey produces detailed thermal images, known as thermograms, which highlight abnormal heat signatures that may not be visible to the naked eye. These surveys are commonly used in housing, commercial units, heritage buildings, and industrial facilities.

Which Types of Buildings Can Benefit From Thermal Imaging Surveys?

We carry out thermal imaging surveys across a wide range of buildings, each with unique inspection needs, including:

• Domestic homes – Ideal for detecting heat loss, damp issues, and underfloor heating faults.
• Commercial premises – Used to assess insulation performance, HVAC efficiency, and electrical systems.
• Schools and public buildings – Support energy audits, maintenance planning, and compliance checks.
• Industrial units – Identify electrical hotspots, equipment faults, or structural weaknesses.
• Heritage or older properties – Non-invasive analysis for moisture ingress, heat bridging, and insulation gaps.

How Much Does a Professional Thermal Imaging Inspection Cost?

The cost of a thermal imaging survey ranges from £250 to over £650, depending on the size of the property, the type of inspection, and the level of reporting required.

Costs are mainly influenced by whether the survey is for a small home or a large commercial site, the number of areas being assessed (such as walls, pipework, or electrical systems), and whether a basic scan or a detailed diagnostic report is needed.

Can Thermal Imaging Be Used to Identify Heat Loss or Damp Problems?

Thermal imaging survey is one of the most effective methods for identifying heat loss and damp problems in both residential and commercial properties.

Cold spots on internal surfaces can reveal areas of missing insulation or water ingress, while thermal patterns on external walls can indicate significant energy loss. Infrared technology also allows for early detection of condensation and moisture buildup, critical for preventing mould growth and long-term structural damage.

What Issues Can Be Detected Through Thermal Imaging?

Thermal imaging can detect a wide range of structural and system-related issues in buildings, including:

• Heat loss – Through poorly insulated walls, roofs, windows, or doors.
• Thermal bridging – Cold spots where building materials conduct heat away more quickly than surrounding areas.
• Air leakage – Draughts or uncontrolled airflow around frames, ducts, or service penetrations.
• Moisture or damp penetration – Water ingress within walls, ceilings, or floors, often invisible to the eye.
• Leaking pipework – Including hidden central heating or plumbing faults behind walls or under floors.
• Underfloor heating faults – Breaks, uneven heat distribution, or inefficient operation.
• Electrical hotspots – Overheating in circuits, fuse boards, or lighting systems that may pose safety risks.

How Do Surveyors Ensure Accuracy With Thermal Imaging Scanning Equipment?

At Thermal Imaging Survey, we follow best practices set out in BS EN 13187 and ISO 6781, adjusting for ambient conditions, surface emissivity, and reflective materials.

Surveys are carried out under controlled conditions where possible (such as heating or cooling the property beforehand), and all images are interpreted by trained thermographers with experience in building physics and defect analysis.

What’s the Process for Booking a Residential or Commercial Thermal Survey?

Booking a thermal imaging survey begins with a short consultation to understand your property type, the issue you’re investigating, and any site access considerations.

From there, we schedule the survey at a suitable time, often during early mornings or evenings to optimise thermal contrast. On the day, our technician will conduct a comprehensive scan using infrared cameras, followed by a detailed report containing thermograms, analysis, and recommended next steps. Reports are typically delivered within 48 hours of inspection.

Do Reports From Thermal Imaging Surveys Meet Insurance or Compliance Standards?

All reports provided by Thermal Imaging Survey meet industry standards for professional documentation and are accepted by insurers, compliance auditors, and relevant regulatory bodies, including:

• Building Regulations compliance – Including evidence for Part L (Conservation of Fuel and Power).
• ESOS energy audits – Contributing to energy-saving strategies and compliance requirements for larger organisations.
• Damp disputes and warranty claims – Providing independent, visual evidence for legal or insurance purposes.
• Preventative maintenance plans – Helping facilities teams identify faults early and avoid unexpected downtime.
• Health & safety protocols – Detecting electrical or structural risks in line with workplace safety obligations.

Are Thermal Imaging Surveys Suitable for Electrical Systems, Roofs, or Pipework?

Our thermal imaging service are widely used to inspect electrical panels and help identify overheating components, load imbalances, and connection faults before they lead to failure or fire risk.

Roof inspections can reveal areas of trapped moisture or poor insulation without removing any coverings. Likewise, pipework, particularly underfloor heating, can be traced, tested, and diagnosed using infrared, enabling targeted repairs with minimal disruption.
