had to have a quick and strange EICR on my flat built in 2005. the engineer said it was okay, but according to the report that came after a few days it was UNSATISFACTORY for no RCDs on a few things. They quoted a full consumer unit replacement, but warned that it might still trip and need more investigations. it seemed a bit off to me especially since they admitted to some typos according to them in the report. Should I really be replacing the whole unit based on this?
