tanith £70 to remove an old shed is still mind boggling. I agree, put it in Freecycle, my area and maybe say that it would be good for a wood burning stove? Could it be re-erected as a shed?
The other option is to chop it up and either take it to the dump yourselves for free or slowly add it to your wheelie bin but that would take an age because you cannot overload it as the poor petals must not strain themselves.
Maybe pay the wood cutter a tenner to cut it up into manageable pieces so that you could put it in your car and take it to the dump. That would take him 5 minutes. It would cost him around £120 to dump it as he is "trade".
