The purpose of this thead was to highlight the difficulty an RP has in choosing a competent contractor and it is interesting to note no-one has suggested any specific schemes or qualifications in their responses.
Im not saying any of the replies are incorrect but I am mindful that when we specify or recommend an RP installs an alarm system to BS 5839 for example, they dont get into the situation of employing someone in good faith only to find out down the line, perhaps in court, that the contractor wasn't competent.
How do I reasonably check the competence of an engineer? I may have been recommended an engineer, the engineer may be punctual, reliable, and fully insured, but that doesnt tell me he or she is competent to install a fire alarm necessarily.
What is it that tells me specifically that an engineer is competent? How would I stand up in court and safely say " yep i did everything i could possibly do to ensure this fellow was competent"
Some people say experience is a pointer toward competency - well where has that experience come from, did they learn from another engineer years back? For years Ive generally done repairs on my own car - does that make me mechanic?
