Beginning in the early 2000s Ireland's state owned public utilities underwent a major reform, following the creation of the Commission for Energy Regulation.

This was part of an effort at both Irish and European level to open up electricity and gas markets and end national monopolies through the separation of customer supply and transmission within public utilities.

Therefore, a new independent subsidiary, Gaslink, has been established to fulfil the functions of the Irish TSO and DSO and will gradually take over much of the operations of gas Networks Ireland.

Today Bord Gáis Energy is a private limited company that is part of the Centrica Group and no longer associated in any way with Ervia or any of its subsidiaries (Irish Water or Gas Networks Ireland).

[9] Bord Gáis Energy is predominantly a supply company, but also offer a range of gas boiler maintenance services to customers.
