How often should Electrical Testing be undertaken?


Domestic Properties

In domestic premises it is presumed that the Occupier will soon notice any breakages or excessive wear and arrange for precautions to be taken and repairs to be carried out.

Commercial & Industrial

Commercial & Industrial installations come under the ‘Electricity at Work Regulations 1989 & formal arrangements are required for maintenance and interim routine checks (as well as periodic inspections); there should also be facilities to receive wear-and-tear reports from users of the premises.


The frequency & type of these routine checks will depend entirely upon the nature of the premises and should be set by the electrical duty holder.


Note that ‘Routine checks’ need not be carried out by an electrically skilled person but should be undertaken by somebody who is able to safely use the installation and recognise defects.

Types of Electrical Testing We Can Provide.

Electrical Installation Condition Reports

Electrical Installation Condition Reports (EICR) are necessary because all electrical installations deteriorate due to a number of factors, i.e. damage, wear, tear, corrosion, excessive electrical loading, aging and environmental influences.


The IEE Wiring Regulations (BS 7671) require that EICR of electrical installations is carried out at such intervals that are consistent with the type of installation, its use and operation, the frequency of maintenance and the external influences upon it.

To comply with these regulations, we would recommend that you seriously consider a report on your premises.


Testing should be completed in such a way as to minimise disturbance of the installation and inconvenience to the user. Where it is necessary to disconnect part or whole of the installation in order to carry out a test, the disconnection should be made at a time agreed with the user and for the minimum period needed to carry out the test. Where more than one test necessitates a disconnection where possible they should be made during one disconnection period.


A careful check should be made of the type of equipment on site so that the necessary precautions can be taken, where conditions require, to disconnect or short-out electronic and other equipment which may be damaged by testing.


Electrical Testing inevitably causes some disruption on the site due to the requirements for disconnecting electrical circuits at various times during the testing. For this reason careful planning and time management is a necessity, and in practice testing is often best performed outside of normal working hours.


The results and extent of electrical testing should be recorded on an EICR and provided to the person ordering the inspection. The report must include the extent of the work, limitations, details of defects and dangerous conditions, and schedules of inspections and test results. Immediately dangerous conditions should be rectified or reported without delay to the relevant duty holder. Other recommendations and observations should be reported using a numbering system to indicate the severity of each observation.

Portable Appliance Testing

When people work with electrical appliances, health and safety regulations state that the appliance must be safe, to prevent harm to the workers. Many types of equipment require testing at regular intervals to ensure continual safety; the interval between tests depending on both the type of appliance and the environment it is used in.


Moreover, Insurance companies are now insisting on PAT Testing being carried out every 12 months (or less) in order to satisfy the conditions of their policy, and local council inspectors (Fire Officers, Environmental Health Officers) are routinely asking for evidence of PAT Testing when they carry out their inspections.


Evidence of testing is clearly visible to workers in the form of ‘Passed’, ‘Tested For Electrical Safety’ and ‘DO NOT USE after’ labels affixed to various parts of the electrical equipment they use.

Thermal Imaging

Using thermal imaging, our engineers can accurately identify existing faults with an electrical installation, as well as predict potential future issues that could save lives.


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 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.
