Testing of Electrical Installations
This Essential Guidance is presented in two parts:
§ Part One: Electrical Installation Condition Report (EICR)
§ Part Two: Portable Appliance Testing / PAT Testing
§ Part Three: Thermal Imaging (Infra-red Technology)
Part One: Electrical Installation Condition Report (EICR)
Over time all electrical wiring systems within buildings deteriorate with age and use. To help ensure the safety of staff and visitors, it is essential that an Electrical Installation Condition Report be carried out every 5 years at a minimum:
A structured programme of Electrical Testing and Inspection will include the following:
§ Find potential electric shock risks and fire hazards in your electrical system
§ Identify any defective or substandard electrical works
§ Highlight any missing earthing or protective conductors
§ Identify any evidence of the electrical system being overloaded
§ Identify wear, deterioration and breakages
§ Identify loose and missing parts and fixings
Electrical systems and appliances have the capacity to seriously injure or even kill, as well as being one of the most common causes of fire. Despite the significant risks associated with electrical faults many installations are unsatisfactory and present a direct threat to building users.
Under the Electricity at Work Regulations 1989, “duty holders” have a “legal responsibility to protect those working or using their premises”.
Preventing harm by “managing and controlling risk” is core to meeting this legal obligation. Failure to identify and effectively minimize risks with your electrical systems can lead to unnecessary costs, serious disruption and injury.
It is recommended that periodic inspection and testing is carried out at the following times:
The Landlords and Tenant Act 1985 requires landlords of properties with short leases to keep the electrical wiring in repair and in proper working order. We recommend landlords arrange for periodic inspection and testing to be carried out by a registered electrician at the relevant intervals shown above.
Inspection and testing of the electrical installations should be carried out more frequently on the places and premises listed here:
Misconceptions about Sample Testing / Percentage Testing
Many people have the misconception that sample testing – also known as percentage testing – can be completed on an electrical installation to ensure compliance with the wiring regulations.
The IET Regulations state you can only rely on Sample testing only if:
§ You hold previous full system records, and
§ The installation is considered to be in excellent condition, and
§ No faults are found during sample testing, and
§ No undocumented alterations have been carried out since the system was new or last tested.
If all of the above are not true, then the installation must not be Sample Tested/Percentage Tested: the installation must be 100% Tested to achieve compliance.
Many companies try to offer a cut price test and inspection – based on sample testing/percentage testing – for installations that require 100% testing. In such cases, the inspection will not comply with the IEE wiring regulations, and consequences include:
§ Invalidated insurance policy
§ An increased potential of an electrical fire on part of the installation that has not been tested.
At HW Solutions we always ensure an electrical test and inspection is completed in accordance with the IET wiring regulations (BS7671). We guarantee that every circuit will be tested, ensuring our clients receive a comprehensive report and certification that complies with the requirements of the regulations.
HW Solutions Ltd. Electrical Installation Condition Report (EICR) – What to Expect
Our test engineers use specialist testing equipment is used to carry out the testing of electrical cables, socket outlets, lighting controls, lighting points, distribution boards and other technical elements as laid down in BS 7671: 2008 AMD 3:2015
A complete shutdown of the electrical system is required for (on average) an hour and a series of mini isolations are also required to complete our works. Our Test Engineers will liaise with the person responsible to ensure that disruption is kept to a minimum.
During the testing, any dangerous items are immediately brought to the attention of the appropriate personnel.
Following the test and inspection you will be provided with a detailed report showing:
§ An overview of the building’s electrical system
§ Test results
§ Defects found – rated C1 (critical/urgent) to C3 (Requires Improvement)
§ Extensive recommendations about the work which needs to be carried out to bring the electrical system up to the required standard.
