Privacy statement and data protection

The Research and Development department (GRAD) is not a legal entity in itself. It works on behalf of, and reports to, all three of the General Lighthouse Authorities that cover the United Kingdom and Ireland, and some associated territories: that is Trinity House (for England, Wales, the Channel Islands and Gibraltar), the Northern Lighthouse Board (for Scotland and the Isle of Man) and the Commissioners of Irish Lights (for the whole of the island or Ireland). Trinity House provides the legal framework within which GRAD works: as such the legal notices provided by Trinity House also cover GRAD. These notices [including the Website Privacy Notice] can be found here.
