I've been having a look and he does seem pretty decent and I've no doubt his stuff will be useful to many. His use of the regulations is a good example.
Noticed on his 'Landlords Inspection' EICR vid, he's questioning IR on the cooker switch reducing from >999 to 8 MEG, incomer to out (about 26 min). Noting in the 'general installation condition' on the cert and questioning future cooker problems with 8 MEG??????. and indicating to the owner/landlord that their cooker may be on the way out, is a bit much, to say the least. IR testing a few cooking appliances could open his mind a bit more on that one. Besides, he's testing fixed wiring, the cooker is not.
