Same here I charge around £220.00 as a Min. standard on a 2 bed House or Flat with a 6/8 way D.B takes around half a day 3 to 4 hours, then on my P.C. to issue a report etc, funny how some Electricians can do it for silly money as I will check at least drop off a socket & switch in each room, check outside the property for external electrics etc. also earthing for Gas water & Oil bonding or if cross bonding is required also, if cables or visible are supported correctly the correct selection of breakers/fused for circuits they are serving.
its not a quick thing as we are there as experts in our field and should give a good account of it.
so when I hear its too dear, I walk away as you will also get a taker and wish them good luck lol
