Electrical Installation Testing

Electrical Inspection, Testing  -   Electrical Installation Certification (EIC)

New commercial board tested for Electrical Installation Certificate.Certelec Ltd provides a full range of Testing and Inspection services on fixed wiring systems, inspecting and testing low and medium voltage systems in commercial, industrial and domestic premises. Fixed Installation Testing (FIT) involves testing the electrical services and systems that conduct electricity around a building. Anything electrical in a building that is fixed such as lighting, socket outlets, air conditioning and other fixed plant needs to be tested. Certelec is a specialist FIT company and has no interest in remedial repairs. Its objective is to present an unbiased installation assessment.


New Installations and Alterations or Additions to the Installation

The IEE Wiring Regulations require every electrical installation to be inspected and tested during erection and on completion before being put into service, this requirement also applies to alterations or additions that include the provision of a new circuit to an existing installation (for domestic installations see Part P of the Building Regulations).

Certelec can provide an independent inspection, test and certification of new installations including a first fix inspection to ensure the installation meets BS7671:2008.A3:2015 and appropriate Building Regulations relevant to electrical work. Certelec also offer a specific service to assist clients in meeting their local Building Control requirements with regard to electrical 'notifiable' work.

Certelec’s Kitemark Licence awarded by British Standards Institution (BSi) is specifically defined to allow us to inspect, test and certify any electrical contractor’s work.

Electrical Installation Condition Report (EICR) - What is an Installation Condition Report?

Commercial board awaiting periodic inspection and test.

The Electricity at Work Regulations state that all electrical systems and equipment used in the working environment should be in a safe condition.
The Health & Safety Executive recommend that to comply with the regulations an inspection and testing schedule must be implemented at all workplaces. INSURANCE COMPANIES are increasingly requiring evidence that electrical installations to Public, Commercial and Industrial locations are safe working and occupation environments, i.e. 'fit for purpose'.

All installations will deteriorate/degrade with use and age. This process is often accelerated by 'DIY' additions/extensions that may NOT have been carried out to Code. Government statistics say that on average 10 people die and about 750 are seriously injured in accidents in the home involving unsafe electrical installations.

An Electrical Installation Condition Report is an inspection on the condition of an existing electrical installation, to identify (in order of priority) any deficiencies against the National Safety Standard (EAWR 1989, BS 7671:2008:A3:2015) for electrical installations. Note: Certelec does NOT undertake Electrical Inspections on a limited scope/range basis, i.e. inspection range less than 100% of the Installation. We believe, such limitation/s are not Industry 'best practice'.

Not just a visual inspection but a full independent inspection and testing of the system

Domestic consumer unit inspected and tested for periodioc nspection report.

  • Identifies if any electrical circuits or equipment are overloaded
  • Detects any potential electrical shock risks
  • Discovers any fire hazards in your electrical installation
  • Finds any defective DIY electrical work
  • Reveals any lack of protective earth /bonding
  • Details the type of fixed wiring system and its condition
  • Checks the suitability of the consumer unit
  • Examines the equipment e.g. switches, socket-outlets and light fittings
  • Tests any residual current devices
  • Discovers any wear and tear, damage or other deterioration

The Report (EICR) identifies and classifies problems according to the IET scale:

The Electrical Installation Condition Report identifies and classifies problems according to the IET scale:

The overall assessment of the suitability of the installation for continued use is stated as,  (Code C1) Danger present, risk of injury. Immediate remedial action required; (Code C2) Potentially dangerous, urgent remedial action required; (Code C3) Improvement required.  To be sited where C1 or C2 do not apply.

When is it needed?

The IET recommends the maximum period between 'EICR' Inspection & Testing is, Domestic 10 years or change of occupancy

Five (5) Years or change in occupancy
Residential Accommodation
Five (5) Years
Buildings open to public 
One (1) to Five (5) years
Industrial Buildings 
Three (3) Years
Special locations,
One (1) to Three (3) Years,  e.g. Medical Locations, Swimming Pools, Agricultural, and Horticultural Premises






Other instances when an Electrical Installation Condition Report should be carried out are:

  • Prior to (new tenancy), and subsequent to a property being let
  • Prior to selling a property or when buying a previously occupied property

All testing is carried out to BS7671:2008+A3:2015. Details of key changes are shown on this page.

The Health and Safety Executive leaflet Electrical Safety and You outlines basic measures to help you control the risks from your use of
electricity at work.
