95% of all goods entering or leaving the UK travel by sea

Our work is for the benefit and safety of all mariners and covers a sea area from Berwick-upon-Tweed on the North East Coast to the Solway Firth in the North West, Gibraltar in the Mediterranean and the Dover Strait—the world’s busiest shipping lane.

As the General Lighthouse Authority (GLA) for England, Wales, the Channel Islands and Gibraltar, we provide over 600 aids to navigation to assist safe passage for vessels of all classes, from lighthouses and buoys to satellite-based systems.

Trinity House’s primary aids to navigation maintain 99.8% availability at all times

Our lighthouses, buoys, lightvessels, beacons and electronic aids to navigation systems assist all mariners at all times and in all conditions. As shipping lanes around the UK grow increasingly crowded and our demand for consumer goods rises, the safe transit of our shipping and our seafarers is more important than ever.

For supermarket and high street shelves to remain stocked and for British exports to reach the rest of the world, Trinity House and the mix of aids to navigation we maintain and develop will continue to guide shipping safely through our waters.

Trinity House works closely with a number of highly-regarded national and international organisations, including the Northern Lighthouse Board, Irish Lights, the Maritime & Coastguard Agency, the UK Hydrographic Office and the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA), to name just a few.
