 He was elected to the Northern Ireland Forum in 1996, then to the Northern Ireland Assembly at the 1998 election as a Sinn Féin member for Fermanagh and South Tyrone.

The Renewable Heat Incentive (the RHI) is a payment system in England, Scotland and Wales, for the generation of heat from renewable energy sources.
 Introduced on 28 November 2011, the RHI replaces the Low Carbon Building Programme, which closed in 2010.
The Renewable Heat Incentive scandal (RHI scandal), also referred to as the Cash for Ash scandal, is a political scandal in Northern Ireland that centres on a failed renewable energy incentive scheme that has been reported to potentially cost the public purse almost £500 million.
 The plan was overseen by Arlene Foster of the Democratic Unionist Party (DUP), the then-Minister for Enterprise, Trade and Investment, who failed to introduce proper cost controls, allowing the plan to spiral out of control.
 The scheme worked by paying applicants to use renewable energy.
 The rate paid was more than the cost of the fuel (the same as in the GBRHI scheme) however, meaning applicants were making profits simply by heating their properties.

Phil Flanagan (born 16 July 1984) is a Sinn Féin politician in Ireland who was elected to the Northern Ireland Assembly in May 2011.

Colm Gildernew MLA (born 27 June 1969) is a Sinn Féin politician from Dungannon, Northern Ireland who has served as Member of the Legislative Assembly for the Fermanagh and South Tyrone constituency in the Northern Ireland Assembly since June 2017.
The 2017 election to the Northern Ireland Assembly was held on 2 March 2017.
 The election was held to elect members (MLAs) following the resignation of deputy First Minister Martin McGuinness in protest over the Renewable Heat Incentive scandal.
 McGuinness' position was not filled, and thus by law his resignation triggered an election.
 It was the sixth election since the Assembly was re-established in 1998, and the first to implement a reduction in size to 90 MLAs (versus the previous 108).
The Low Carbon Building Programme (LCBP) was a payments system in England, Scotland and Wales.
 The UK Government programme was administered by BERR (formerly the DTI) and ran from 1 April 2006 until its closure to new applications on 24 May 2010.
 The scheme was replaced by the Renewable Heat Incentive in November 2011.
