I have to agree with @essex - it is clearly stated within an EICR if you bother to read it that the date of next inspection is subject to dangerous and potentially dangerous defects being remedied, and further investigation being carried out where required. There is no need to reissue another EICR with the word "Satisfactory". Certified remedial works for the "Unsatisfactory" EICR make it now satisfactory. The original EICR is not amended to read "Satisfactory" - there is no need for it to. The certification proves that relevant issues have been corrected.
