I agree- my real gripe is that the limitations of the test were not pointed out and the only recommendation was a complete rewire.
Anyway I have now had a discussion with the original tester. As expected he had done only one insulation test. I said that the entries in the EICR form were misleading as values were put in boxes for specific insulation measurements that were quite probably incorrect for those insulations, with no note of the fact. (Maybe this is normal practice, but I still think it's wrong.) He waffled about other defects of the installation, but all the defects he had listed on the EICR could be fixed by a new CU and better earth connection and bonding.
We did not come to an agreement! But shortly afterwards his secretary phoned and offered me a full refund. So I'm grateful for the discussion here, it has helped me understand the issues and get my money back.
I will now arrange for a retest with separate insulation measurements, followed by a bit of investigation paid at an hourly rate. Fingers crossed, I might avoid retiling and replastering.
