An agricultural contractor, for example, has just finished their autumn work, which is large part of their business. Over the winter, they will be doing very little, and so the next few months they will have little contracting use and little use of RUC, whereas over the last six to eight weeks, they've done maize silage and other things like that and will have had a massive transport bill. How will that relate? They're going to get a discount for the period of time they're not working, essentially, and having to pay huge RUC at the time that they're most busy.
