I was about to talk about the MOT analogy (or otherwise) in a reply to Adam's recent post!
This is a major difference between MOTs and EICRs. With MOTs there's no "... and chances are ...". If one leaves the vehicle at the 'test centre' for repairs, then they are obliged (by law) to re-test and issue a 'pass' MOT certificate without charge. With EICRs, if one lets the EICR inspector' do the remedial work, there's obviously no obligation on them (legal or otherwise) to produce a new, 'clean' EICR after completing the work - and, at least in my experience, few, if any, will volunteer to do that for no extra charge.
There is also a long list of (mainly minor) 'fail problems' (including tyre replacement) in relation to which the original tester is obliged to undertake a free 'partial retest' (and provide a pass cert) if one returns the vehicle to the original 'test centre' the next working day - see
(here) .
Not necessarily. If you take it back to the original test centre within 10 days, only a 'partial retest' (of the items which failed) is required, for which a 'partial retest fee' (but never a full fee) 'may' be charged. After 10 days, yes, you would have to pay for a 'full price retest'.
Any of that is possible. However, in that situation, 2(b) will usually result in your getting a clean MOT cert (NOT some new problem being found) - at 'full price' but, nevertheless, very probably less than you would have paid for the 'unnecessary' repair.
One catch these days is that if any 'dangerous' problems are reported on the initial MOT failure paperwork, one is not allowed to drive the car to anywhere else for repair, leaving one with few options. I suppose that is analgous to a C1 in an EICR but, again, that does not oblige one to get the inspector undertake the remedial work.
