Some of the money raised goes into the costs of operating the system. Local authorities must report their income from parking fines and charges and must also state what any surplus is spent on. Typically the revenue from such schemes (if lost parking fees from infringing motorists are excluded) is greater than the cost of running the scheme and the surplus goes into the public purse, along with the parking fee income. The surplus revenue is ring-fenced to be used for transport related expenditure unless the Council is judged to be 'excellent' by the Audit Commission, in which case the surplus goes into the Council's general budget (as is the case for Kensington and Chelsea). In 2005/6 the City of Westminster received GBP 65.4 million in parking revenue for on-street parking. From one road in London, £3.2 million was raised in the year 2005-06.
