Thats why I was saying ( well i tried to but it came across all sort of wrong )......it is Really important to fill in the description of installation box.
Its not all about "what you have done". BUT "what you have not".....if you get my drift
The DB change cert is very confusing. You are supposed to only certify just the DB but end up doing half EIC & EICR.
To do a cert for just your DB then the only test results should realy just be the supply from the meter to the DB. If you have replaced like for like breakers them why should you have to test for that. Just show RCD trip times if needed. Anything else should be on a EICR.
This does not happen because we all feel it is unnecessary to do two certs.
