If your EICR says remedial or further investigative work is required, you must act on this within 28 days of receiving the report, unless a shorter period is specified.
When the work is complete, you do not need to do another EICR. But you must provide certificates and receipts to your tenants and local housing authority proving the remedial work was finished as required. The electrical installation that was in question must now be safe for continued use and you should have written confirmation of this.
