Although small skips tend to be less expensive than they are to rent; it may be prudent to use a bigger skip if you do not know how many items will come in and out of this size. Depending on how many deliveries and collections a customer has arranged, renting this larger-sized bin may end up saving them more money. Additionally, waste sites generally charge customers disposal fees per kilogram or per pound based on the overall weight of the waste; thus, if the heavy items are included in the bin, the rental prices for the bin may increase significantly. Therefore, customers should also consider using alternative methods of disposal for their heavier-weight items, to reduce the cost of their overall skip bin rental combination.
