Local Lighthouse Authorities

Before an Aid to Navigation (AtoN)is established, altered or removed, a Local Lighthouse Authority (LLA)must seek prior consent from Trinity House who will prescribe the navigational requirements.

LLA’s can be port/harbour authorities, utility companies, councils or operators of offshore structures such as production platforms and windfarms. Legislation empowers Trinity Houseto inspect all AtoN’s under LLA management. This inspection ensures that AtoN’s continue to safeguard the mariner and meet international standards of performance. It also allows the LLA to seek advice regarding anyissues they may have with their AtoN’s.

For many LLA’s, the inspection forms an important external input.There are more than 10,000 local Aids to Navigation inspected annually by Trinity House. Responsibility for the performance of the local AtoN’s rests with the LLA’s.

In addition, Trinity House is responsible for marking shipwrecks which occur within our area of jurisdiction .
