The Prices and Incomes Act 1966 c. 33 was a United Kingdom Act of Parliament, affecting UK labour law, regarding wage levels and price policies. It allowed the government to begin a process to scrutinise rising levels of wages (at around 8 per cent per annum at that time) by initiating reports, and inquiries, and ultimately giving orders for a standstill. The objective was to control inflation. It proved unpopular after the 1960s.
