So what does this bill do? Well, what it does is actually tightens up the definition around retentions. People listening to this debate may wonder what retentions are. It's all to do with the money that is paid by subcontractors as part of the process of entering into a big construction job, for instance. Some of that money has, in the past, been mixed wrongly and poorly, in commercial terms, with the larger principal contractor in a way that has meant that if that larger main contractor falls over—goes into receivership or liquidation—then that money that is due to the subcontractors is not payable and not available to them. That's a huge problem for small businesses who are the subcontractors.
