Concluding comments (unless NCArcher wants to add something)
Thanks to all for you inputs.
NCArcher is right, we did seem to stray from the original question and I thank you for pointing that out.
However, NCArcher did also stray from what I originally said. I had not decided to not pay the asking price for the materials (although I had questioned it). Furthermore, because I didn't obtain a quote in the first place (I will most likely do so next time!), I do not think I am necessarily obliged to pay whatever is asked. That amounts to writing an open cheque!
If the electrician charged me $100 for the standard GPO fitting (which probably cost him $10), and his labour at $80 ph and the cable at $20 per metre etc, etc, I would definitely object.
Since no-one has really come up with comments which provide me with a worthwhile way of taking him to task over what I definitely regard as rip-off materials pricing, I have decided I am not going to have an argument over the $1k of what I regard as excessive markups. I have already paid him $3.6k and will now pay the extra amount.
That is after he checks what is suspect is a live, unterminated wire awaiting a final GPO once the kitchen work is completed. And, I will be getting another electrician to do the final (and further) work.
I know $80ph is market for this work, but I am not prepared to bulk that up by paying 3 times what the materials can be readily bought at. I regard that as a sneaky way of overcharging me.
Having said all that, again, thanks for all your comments.
Regards
Gordon
