I've chopped off information that would identify the company and contractor.
I'm afraid there are some concerns about that schedule of test results.
There is certainly nothing on there to say the RCD works, there is no test data recorded for the RCD at all, not even that the test button works.
My top concern - there are some circuits that apparently had no R1+R2, R2 or Zs test which means there is no way of knowing that the protective device will trip under fault conditions, which is rather a fundamental aspect of testing.
My other big concern - if we believe the figures, there is one sockets circuit that has VERY low insulation resistance suggesting poor condition or damaged wiring and that would have raised concerns for me, and I'd have given that a C2.
One of two things happened. He either did an incomplete and in my opinion not very competent job, or he found enough things wrong to make it rather pointless continuing testing and stopped short.
Personally I wouldn't proceed with any recommended remedial work based on such incomplete test data.
Would you mind sharing your approximate location? There may be members nearby who can help resolve this.
