At Hexo Electrical Testing we offer an Electrical Thermographic Survey service to our commercial clients. A thermographic survey is usually used to supplement regular EICR testing, and the recommended frequency is once per year.

Why have a thermographic survey?

An electrical thermographic survey carried out by a skilled electrical inspector will identify any unusual hot spots in the fixed electrical installation. 

It does not require any down time for the business as the survey is performed live and under normal operating conditions, so nothing is turned off. In fact, we need the installation to be under load so we can detect any issues using an electrical thermal imaging camera

A thermographic survey should be carried out once per year between EICR testing intervals.

    Very helpful and easy to work with, we needed to make several repairs to improve our EICR report and they explained everything on the report and what they'd do, and scheduled in the work quickly. The electrician was friendly, professional and left the house in excellent condition.

    Really responsive and flexible to fit in a job that we needed doing at incredibly short notice (same day!) Proactive, communicative, professional and really helpful. Really clear and easy to understand pricing, and the online invoicing system was a total dream (which is definitely not always the case!) and allowed me to quickly pay invoices while I was running today and so meant I didn’t hold anything up. The whole service today was outstanding - thank you.

    Right from the beginning with the first phonecall to the completion of all work necessary for an electrical certificate, they were professional and courteous. It wasn't cheap but I paid for a quality service which seems to be a rarity in today's world. Well done Hexo

    I had a fantastic experience with Hexo. They responded very quickly to my enquiry email and followed up with an email. They then had an engineer with me by the same afternoon. The two men I dealt with were so incredibly friendly, helpful, reassuring and informative. I intend to use them again in future. Highly recommend.

    I enquired about the EIDR check and was given a fix price. They arranged appointment with my tenant and fixed the date They attended at the appointed date and completed the test. Job well done. I will definitely use then again as the price was reasonable too

    I needed an urgent EICR for my rental property and Hexo stepped in when I was let down by my usual supplier. They gave me a good quote, that they stuck to - no unexpected extras unlike some, turned up on time and stayed in touch. I needed some subsequent work done and again, great communication, a fair quote and the work was done on time and to a great standard. Would recommend and will use again.

    What is checked during an electrical thermal imaging survey?

    Areas that will usually be checked are:

    • Distribution boards
    • Bus bar chambers 
    • Switchgear 
    • Contactor enclosures 
    • General enclosures and junction boxes

    Typically, the survey will highlight any:

    • Loose connections
    • Overheating circuit breakers or fuses 
    • Abnormal loading 
    • Overheating distribution equipment

    What happens after an electrical thermal imaging survey?

    If any issues are detected, then we can undertake remedial work and rectify the problems to make the installation safe. 

    The process is quicker and much less disruptive than EICR testing but should be undertaken in conjunction with a regular Commercial EICR.

    It’s an excellent way to maintain a safe fixed electrical installation, and in most cases insurance companies will reduce premiums if thermographic surveys are undertaken, as the risk of an electrical fire is reduced.

    Who needs a thermographic survey?

    An electrical thermographic survey is recommended for all commercial premises and businesses as it is an excellent way to be vigilant and reduce risk of dangerous electrical defects. 

    Your insurance company may insist that you have a survey undertaken, or one may be incentivised by a reduction in premiums as it is a recognised method of reducing electrical incidents.

    How much does a thermal imaging survey cost?

    Electrical thermal imaging survey costs depend on how many items we will be inspectin

    g. As we are an electrical inspection and testing company, we do not require a separate competent person to open the electrical items for us, so there will be no additional costs by using us.  

    Please contact us to discuss your requirements and we will provide you with a fixed price for your electrical thermographic survey.

    How often should a thermographic survey be carried out?

    It is recommended that a thermographic survey is carried out once per year, in between a regular Commercial EICR

    Is there any disruption?

    There is minimal disruption as because we use an electrical thermal imaging camera, we do not need to isolate any electrical supplies, so all power will remain on.

    We will need to gain access to every piece of equipment that is to be inspected and then open this equipment to perform the thermal imaging survey.
