In which case you may want to ask your council if they will remove it for free.
A friend in Essex got them to do that recently as it was below 40Kg
Again counties differ, but worth a try.
We bought the house from the bloke who bought it on "right to buy" he must have been quids in!.
Due to my other dealings with the Council.I very much doubt they will do anything for free, think the charge £200 to collect it from your house plus disposal fee..
