Some people have different sizes of bins. Why is this and what are my options?

There are two sizes of bin in use, 240L and 140L. The smaller bins have been provided where gardens and storage space is smaller. As our costs arise from making the collection, not disposing of the waste, then the charge we make is the same regardless of the bin size. Please make clear at the point of ordering if you require the smaller bin size. If you order one bin size but later decide to change then there will be a delivery charge.
