The Department for Transport's "Guidance on New De Minimis Rules for Busy Subsidy Contracts" (2004) notes that "The 1985 Transport Act (as amended by the 2000 Transport Act) introduced the provisions which govern the duties of local passenger transport authorities to secure local bus services where these would not otherwise be met. In the majority of cases these services have to be secured through competitive tender. The Service Subsidy Agreements (Tendering) Regulations provided local authorities with the scope to let any individual bus subsidy contract in any one year up to a certain maximum value without the need to competitively tender (the de minimis limits). There was also a maximum value that de minimis contracts could be let with any one operator in any one year."
