Before we carry out a fuse board change in an ideal world we would carry out a full EICR or Electrical Installation Condition Report, this is not to be confused with PAT testing which is the inspection and testing of portable appliances.
This inspection and testing will highlight any immediate safety issues along with a summary of the condition of the electrical installation.
One important requirement is the suitability and presence of Main Equipotential bonding conductors. These bonding conductors connect mainly the gas and water pipes if they are constructed of a conductive material. It is essential these conductors are in place and of adequate size.
Due to the increased safety features of the new 18th edition consumer unit, there may be instances where the existing house wiring carries faults which are not detected by the old rewireable fuses or MCB’s.
Because the fuse board change is classed as notifiable work under Part P of building control an Electrical Installation Certificate will need to be issued upon completion along with a notification to the Local Building Control Authority.
It is not acceptable to change the fuse board and leave these faults in place.
If a customer decides not to have an EICR completed they should be aware that there may be instances in some cases where additional works need to be completed to satisfy the requirements of BS7671.
How much does an EICR cost? on average a 3 bedroom house would be around £120 to carry out an EICR.
