Spending a penny would cost more at the busiest times under local authority plans for dynamic pricing in public lavatories. Cash-strapped councils have opened the door to using real-time data to move prices up and down according to demand under controversial "surge charging" in public toilets. Concerns over dynamic pricing have peaked in recent years after prices for the highly anticipated Oasis reunion tour tickets more than doubled, prompting a regulatory investigation. Yet it is becoming an increasing feature of life in Britain, with The Telegraph revealing last month that car parks had started charging "dynamic tariffs" for the first time. In the Cotswolds, council documents showed "the concept of dynamic pricing between summer and winter was a potential option" as part of the district's "budget-setting process" for public lavatories.
