£30 an hour is poor when you take off all expenses, as said £30 x6 is £180 take off £50 tax and ni£10/£20 fuel! That takes your £30 an hour down to £20 an hour. if you then look deeper cost of equipment needs covering then you have water costs/ van depreatiation food/drink whilst working van tax, van insurance, van servicing..... The list goes on.... Then that £20 soon ends up £10 an hour which isnt much to write home about at all.
