Electrical Installation Condition Report

Electrical installation condition report gives a clear indication on the condition of an electrical system. To understand the condition of the system a series of technical tests are completed.

  • Insulation resistance – verifies the condition of the insulation of cable in ohms, The older the system the lower the reading usually.
  • Earth loop impedance – verifies there is a good connection to earth and the resistance of the circuit is low enough for the breaker or RCBO to operate in the required time in fault conditions. The values are set out by BS7671-18th edition
  • RCD test – This verifies all installed RCDs and RCBOs operate in the required time set out in BS7671-18th edition.

On top of the technical test a full visual inspection is carried out, a functional test of all accessories and verification of systems conformity to British standards. Upon completion a NICEIC approved contractor report is generated. This will detail all the tests completed, the extent of the system inspected and any failures and the severity. A coding system from 1-3 is used code failures.

  1. Requires immediate attention – This level of failure is for the most serious and high risk faults. IE if the supply to the installation is arcing and could cause a fire.An electrical danger notification may be issued, and system shut down.
  2. Requires urgent attention – No immediate danger but in the event of a fault there could be a high risk. IE not bonding present, exposed conductive parts could become live in fault condition.
  3. Improvement recommended – no danger present and the system is safe, but the system could be improved by upgrading or repairing parts of the system.

If there is not a classification for a fault or problem with system. The FI is coded and further investigation should be completed without delay. A system cannot achieve a satisfactory rating with any code 1,2 or FI on the report. Once the report has been completed remedial works can be quoted and should be completed within 28 days.

We will undertake an EICR on any type of building, see below some of the types and there EICR requirements for frequency of inspections.

  • Landlord demise of blocks of flats – Routine yearly check/every 5 years.
  • Domestic(houses/Flats) – Change of occupancy/every 10 years.
  • Commercial – Routine yearly check/Change of occupancy/every 5 years
  • Buildings open to public – routine yearly check/every 3-5 years depending on building type.
  • Educational – routine check every 4 months/ every 5 years.
  • HMOs and residential accommodation – routine yearly check/every 5 years.

    All our EICR works comply with BS7671-18th edition
