Thermal Imaging & Thermography
See the invisible threat before it stops your business. TMUK Group Ltd provides advanced, non-intrusive electrical thermographic surveys to detect dangerous faults, prevent catastrophic fires, and guarantee zero operational downtime.
What is an Electrical Thermographic Survey?
In an electrical system, excess heat is the first sign of impending failure. Loose connections, overloaded circuits, phase imbalances, and degrading components all generate abnormal heat profiles long before they trip a breaker or cause a fire.
Thermal Imaging (Thermography) uses highly calibrated infrared cameras to measure the radiant heat emitted by your electrical infrastructure. Unlike standard electrical testing, thermography is completely non-destructive and is performed while your equipment is running under normal or peak loads. This allows our engineers to spot hidden “hot spots” in real-time, effectively stopping electrical fires before the first spark is ever struck.
Why Asset Managers & Insurers Demand Thermal Imaging
An EICR is fantastic for checking the fundamental safety of your wiring, but it requires shutting the power off. Thermal imaging is the ultimate complementary service because it tests the system exactly when it is working its hardest.
- 🔥 Zero Operational Downtime: Because we test under load, your servers, manufacturing lines, and office operations never have to be shut down during the survey.
- 🔥 Insurance Compliance: Corporate insurers are increasingly demanding annual thermographic surveys. Demonstrating proactive thermal maintenance can lower your premiums and guarantee your payouts in the event of an incident.
- 🔥 Massive Cost Savings: Identifying a failing £50 breaker today prevents a £50,000 catastrophic main board failure (and days of lost revenue) tomorrow.
Statutory Duties & Fire Prevention
Thermography is recognised by the Health & Safety Executive (HSE) as a highly effective method for meeting your statutory maintenance obligations.
- The Electricity at Work Regulations 1989 (EAWR): Duty holders must ensure systems are maintained to prevent danger. Thermal imaging is physical proof of proactive, preventative maintenance.
- BS 7671 Compliance: Helps verify that equipment is not exceeding the thermal limits outlined in the IET Wiring Regulations.
- The Regulatory Reform (Fire Safety) Order 2005: Electrical faults are the leading cause of commercial fires. Thermography is a critical component of a robust Fire Risk Assessment strategy.
Our Expert Thermographic Process
Our ITC-certified (Infrared Training Center) engineers use industry-leading thermal optics to provide crystal-clear diagnostics of your main switch panels, distribution boards, server room infrastructure, and motor control centres.
1. Live Environment Scanning
We safely remove panel covers and scan the live components under typical working loads, searching for thermal anomalies, unbalanced loads, and high-resistance connections.
2. Side-by-Side Analysis
We capture both an infrared thermal image and a standard high-definition digital photograph of the exact same component, allowing your on-site team to instantly recognise the location of the fault.
3. Comprehensive Reporting
You receive a detailed report outlining the exact temperature differentials, the severity of the fault, and actionable, costed recommendations for immediate remedial repairs.
Transparent Pricing & The TMUK Advantage
Our commercial thermographic survey pricing is highly competitive across the UK:
- ✅ Minimum Site Rate: £350 (Covers up to a half-day or smaller sites)
- ✅ Standard Full-Day Rate: £650
- ✅ Volume: We typically image between 50 to 100 distribution boards or panels per day, depending entirely on equipment access and site logistics.
Why Qualified Electricians Matter: The Panel Cover Issue
Crucially, because TMUK Group Ltd utilises fully qualified electrical contractors, we are authorised to safely remove the covers on your distribution boards and control panels during the inspection.
Many standalone thermal imaging companies are not qualified electricians. They either take thermal images with the panel covers left on—which is essentially a pointless exercise for detecting internal component faults—or they require you to pay for a separate electrician to attend site just to remove the covers for them. With our team, you receive a complete, compliant, and accurate diagnostic service in a single, cost-effective package.
