Irish Lights statutory duties

The Commissioners of Irish Lights is vested under Section 634 of the Merchant Shipping Act 1894 with the responsibility for superintendence and management of all lighthouses and other aids to navigation for Ireland (North and South) and the adjacent seas and islands. 

The Merchant Shipping Act 1995 Section 195 (1) empowers us with the same function for Northern Ireland and adjacent seas and islands.

Aids to navigation: We are responsible for discharging the Irish Government's obligations under the SOLAS Convention 1974 to provide marine aids to navigation (AtoN) in the Republic of Ireland and the UK government’s SOLAS obligations to provide marine AtoN in Northern Ireland.

Aids to navigation are provided to standards set by the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA).

Wrecks: We have responsibility for marking and removing wrecks in the Republic of Ireland under the Merchant Shipping (Salvage and Wreck) Act 1993, Part IV and in Northern Ireland under the Merchant Shipping Act 1995, Section 253(1). 


Funding of service

We are funded from three sources:

  • Light dues are collected from commercial ships arriving into Irish and UK ports and paid into the General Lighthouse Fund (GLF) for the UK and Ireland.  The Revenue Commissioners Customs & Excise division collect the light dues in the Republic of Ireland and the Institute of Chartered Shipbrokers has this responsibility for Northern Ireland.
  • The Irish Government contribute to the fund under a forumla agreed between the Irish and UK governments.
  • Funds generated by our commercial activities.


Our Board

The Board meets eight times a year to review and update its strategies and to oversee the effective and efficient operation of the organisation.  From 2013, new Commissioners will be appointed for a five year term with the possibility of a renewal for another five years.  Appointement of new Comissioners to fill vacant positions is advertised in the national press in both the Republic of Ireland and Northern Ireland.  Such appointments are subject to negative resolution by An Taoiseach.  Commissioners do not receive any remuneration for their services.
