The Immigration (European Economic Area) Regulations 2006[1] (or EEA Regulations for short), amended by SI 2009/1117,[2] SI 2011/1247[3] and SI 2015/694[4] and which have now been mostly repealed and superseded by the Immigration (European Economic Area) Regulations 2016, was a piece of British legislation which implemented the right of free movement of European Economic Area (EEA) nationals and their family members in the United Kingdom.

Although Swiss citizens are covered by a separate bilateral agreement; they are treated basically the same as EEA nationals.

UK regulations have specific criteria for extended family members, including unmarried and same sex partners.

Workers from recent member states have the right to move to the UK, but their access to the labour market is limited.

One example is a failure to correctly implement the Surinder Singh ruling of the European Court of Justice.
