Periodic Electrical Inspection & Testing Frequencies


Why Do We Need To Test?

There are various factors that can lead to an electrical installation to degrade over time.


Electrical accessories such as light switches and socket outlets can sustain damage through use or even misuse, cables may deteriorate and if not installed correctly may sustain damage too also with connections possibly becoming loose.


The type of site, electrical installation and use of the premises all play a part in the deterioration of the electrical system. Along with issues like external influences (rain/snow/ice), extreme heat and possibly exposure to chemicals, one area that often effects the safety of electrical installations is the maintenance, or in many cases, the lack of maintenance.


Testing Provides Preventative Maintenance


As business continuity is an important factor for most businesses, finding a fault before it’s becomes a problem is key to business success.


This will to only save you time and money but may well also save lives too.


Electrical Test Midlands can help you, and your business comply with the many aspects of electrical compliance, from Fixed Wire and Portable Appliance Testing and thermal imaging.

electrical compliance services

Our electrical compliance services address all the demands of relevant legislation, regulations and standards that surround safety in electricity. Unlike many providers, we offer total compliance services, from testing to repairs, allowing our clients to rest assured that the electrics in their working environment are safe.


Making sure you are operating in a safe environment and maintaining electrical compliance with safety legislation is vital. Electrical Test Midlands are experts in providing clients with all the information and required services they need to maintain total compliance.



Is the systematic checking of any equipment which has a plug. Our certified engineers ensure that the portable appliances in your working environment are thoroughly tested, delivering a full report within hours of completing the tests.

Periodic Fixed Installation Testing

Involves testing the electrical circuits and systems that distribute electricity around a building. It covers all the hard wiring in a building, whether that building is commercial, industrial or residential. Read More about Fixed Installation Testing or contact us for a quote.



Thermal Imaging

Is a very effective means of diagnosing electrical faults and failures. Loose connections, which can lead to a build-up of heat and fire, can be identified using thermal imaging cameras, operated by our experienced engineers. Read more about Thermal Imaging or contact us for more information.



Once electrical safety testing has been completed the resultant remedial repairs must be completed.  The risk is that an accident or incident occurs after tests identify a fault but before that fault is remedied. Electrical Test Midlands is unique in that we will identify the faults and offer an Electrical Remedial Repairs service – contact us for a quote.

Thermal Imaging

Thermal Imaging from Electrical Test Midlands
Thermal Imaging

By detecting anomalies often invisible to the naked eye, thermography allows corrective action to be taken before costly system failures occur. Thermal Imaging or Thermography is the process of using a special camera designed to look only for heat by way of infra red (IR) energy waves. Potential problems can often be found due to excess heat being released by an electrical system, even those which would normally produce some heat when performing at their optimum level.

If undetected these problems can lead to failure and can result in expensive production loss or downtime and, in the most extreme case, can lead to fire. A regular programme from electrical test midlands of thermal imaging as part of routine maintenance can highlight potential problems long before any event. As a result any required repairs can be planned for in terms of both time and budget. In short, it is an invaluable resource for predictive maintenance. Thermography has applications in many different areas which are listed below.

Thermography can detect the following in electrical systems:

Loose connections
Phase imbalances
High resistance in fuses and switchgear
Thermography can detect the following in mechanical systems:

Motor overload
Worn Bearings
Boiler seal leakage
Insulation breakdown
Hydraulic, steam and hot water systems
Tank levels and insulation
Thermography can detect the following in buildings:

Continuity of insulation
Flat roof leakage
Heating, ventilation and air conditioning
Cold storage thermal gain
