The Gangmasters Licensing Authority (GLA) was established on 1 April 2005 by the
Gangmasters (Licensing) Act 2004, passed in the aftermath of the
2004 Morecambe Bay cockling disaster. The authority was handed a remit of preventing the exploitation of workers in the fresh produce sector — agriculture, horticulture, shellfish gathering, and all associated processing and packaging. Initially, the authority sat under the control of the
Department for Environment, Food and Rural Affairs (Defra) but on 9 April 2014 it was transferred to the control of the
Home Office. In making the announcement, Prime Minister
David Cameron stated that the move would ‘strengthen its enforcement and intelligence capabilities’ by putting it directly alongside the considerable resources of the
National Crime Agency. On 30 April 2017, the GLA was renamed the Gangmasters and Labour Abuse Authority (GLAA) as part of reforms under the
Immigration Act 2016. The government invested an additional £2 million to extend the authority's remit, allowing it to prevent, detect, and investigate worker exploitation across the entire economy. Specialist Labour Abuse Prevention Officers (LAPOs) were given powers under the
Police and Criminal Evidence Act 1984 to investigate labour market offences, including the forced or compulsory labour element of
modern slavery, across England and Wales. A new Joint Slavery and Trafficking Analysis Centre opened in April 2017. The dedicated unit - made up of analysts from the
National Crime Agency, police,
Border Force,
Immigration Enforcement,
HM Revenue and Customs, and the GLAA - mirrors a joint working model successfully used to gather intelligence on terrorism. The Immigration Act 2016 also created the position of the Director of Labour Market Enforcement, which provides strategic direction for organisations regulating the UK labour market: • GLAA •
HM Revenue and Customs' National Minimum Wage unit •
Employment Agency Standards Inspectorate The first Director of Labour Market Enforcement was Sir David Metcalf, The position is currently held by
Margaret Beels, who had previously served as chair of the GLAA and its predecessor agency for more than 10 years. In July 2019, the government opened a public consultation on plans to establish a new single labour market enforcement body as a feature of its overall
Good Work Plan. This would combine the GLAA, HM Revenue and Customs' National Minimum Wage unit, and the
Employment Agency Standards Inspectorate into one agency tackling labour exploitation and enforcing workers' rights. The outcome of the consultation supported the proposal. legislation to create a single enforcement body has not yet been enacted and the delay with progressing the proposal has been widely criticised by organisations supporting vulnerable workers. In its
2024 election manifesto, the
Labour Party proposed the creation of a
Fair Work Agency, which would consolidate the powers of the GLAA and those of the Director of Labour Enforcement. The
Employment Rights Act 2025 became law on 18 December 2025 and the GLAA became part of the Fair Work Agency on 7 April 2026. ==Enforcement==
