The Office of Fair Trading (OFT) is a not-for-profit and non-ministerial government department of the United Kingdom, established by the Fair Trading Act 1973, which enforces both consumer protection and competition law, acting as the UK`s economic regulator. The OFT`s goal is to make markets work well for consumers, ensuring vigorous competition between fair-dealing businesses and prohibiting unfair practices such as rogue trading, scams and cartels. Its role was modified and its powers changed with the Enterprise Act 2002.
