Over time all electrical installations degrade because of their age and usage and need periodical testing. These installations require inspection and testing at regular intervals to make sure they are in good working order. On job completion you will be issued with an EICR (Electrical Condition Report).
Who should carry this out?
By registered electricians with experience of periodical testing. They will check the condition of the electrics against the UK standard for the safety of electrical installations, BS 7671 Requirements for Electrical Installations (IEE Wiring Regulations).
