Commercial Thermal Testing

Thermal imaging and testing is a life-saving, fault-finding solution.

Most electrical faults are caused by overheating due to loose connections or overloading, which can lead to fires.

As part of your commercial building’s Planned Preventative Maintenance (PPM), Thermal Testing can help you identify existing faults and foresee future potential problems in your electrical installation.

Your Electrical Safety is in Trusted Hands!

Thermal Testing is a complement to your electrical maintenance, such as Fixed Wire Testing, to identify problems before they happen, and therefore act as an added electrical safety precaution. It’s pretty clever, right? Here are a few reasons why you might’ve arrived on our site to seek this out today:

You've just acquired a new premises where the Fixed Wire Testing isn't due for a few years but you'd like to have a check on the electrics

You've experienced an electrical fire due to overloading issues, and want to utilise Thermal Testing to help you identify potential problems before they actually arise

You've heart about the benefits of adding Thermal Testing on to your Planned Preventative Maintenance (PPM) plan, including extending your equipment's lifecycle, potential energy savings and anticipating/removing remedial costs

How Thermal Testing Complements Your Electrical Safety Plan:

Electrical faults and failures can result in business downtime and data loss – the worst case scenario is someone gets hurt. Here are the three steps to demonstrate how you can implement your electrical safety with a little help from thermographics:

NICEIC Platinum Promise Gold Badge


Annual Testing: Have a competent specialist carry out thermal testing of your electrical installation periodically (we recommend every year) to identify high levels of heat causing faults in your electrical installation.


Prevent Fires: Thermal imaging can also help detect faults before they happen, as much as 6 months to a year in advance! Knowing this can help you keep your people and your premises safe from the threat of an electrical fire.


Plan Diligently: By incorporating thermal imaging as part of your building’s routine maintenance, required repairs can be planned for well ahead of time, helping you to avoid unwanted surprises which could strain your budget.

Thermal Testing Explained:

Ever wanted the power of a crystal ball? With Thermal Imaging, or Thermography, you can. 

This resource is indispensable for your business as it finds electrical faults in your building which are invisible to the naked eye, and can even predict future faults 6 months to a year before they happen!

The way this technology does it is by looking at the heat given off by way of infra red (IR) energy waves. Check this image out to the right – you can that there’s red patches in the middle of the screen indicating there’s overheating in the panel it’s pointing at. This would then prompt further investigation and corrective action to be taken.

Many building managers opt to have Thermal Testing as part of their Fixed Wire Testing (EICR). It’s not a requirement to have Thermal Testing, but it is a requirement, as per the Electricity at Work Act 1974, to have systems maintained to prevent death or injury from electrical causes. And Thermal Testing, along with your Fixed Wire Testing, is your resource to help you do this.

Thermal cameras were a huge hit during the pandemic, but the truth is, us electricians have been using them for years to measure heat on electrical equipment to help anticipate failures and overloads, which can be detrimental to health and safety.

What Happens During Thermal Testing?

Compared to Fixed Wire Testing, which gives you your Electrical Installation Condition Report (EICR), and is typically required every 5 years (depending on your building), Thermal Testing is a complementary measure that can be used to identify faults, both existing and those which haven’t fully materialised. 

Thermal Testing is non-invasive because it only requires pointing a camera at a given area. It should be done when the building is at it’s busiest (i.e. when there’s the most amount of electricity being used) to get an accurate reading of the extent of any electrical damage (or pending problems). 

Fixed Wire Testing, by contract, should have all the electricity shut off and is pretty invasive, plus a big part of it involves visual inspections, and signs of overheating are not always obvious enough to be visible.

We advise Thermal Testing is carried out every year to help identify problems as soon as they happen and avoid letting faults fester.

The following can be detected during your Thermal Testing visit:


Circuit Overloads

Loose Connections

Phase Imbalances

High Resistance in Fuses
