Trinity House is a charity dedicated to safeguarding shipping and seafarers, providing education, support and welfare to the seafaring community with a statutory duty as a General Lighthouse Authority to deliver a reliable, efficient and cost-effective aids to navigation service for the benefit and safety of all mariners
Safety at Sea
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
Our aids to navigation help thousands of mariners annually to navigate their way safely around some of the UK’s busiest waters including the Dover Strait—the world’s busiest shipping lane.
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.

As a General Lighthouse Authority, Trinity House provides over 600 aids to navigation such as lighthouses, buoys, lightvessels and beacons.
Trinity House issues Notices to Mariners to broadcast changes to our aids to navigation and reviews their ongoing requirement on a regular basis.
We work with local ports and harbours to audit and inspect over 11,000 local aids to navigation.
We monitor our aids to navigation 24/7 from the Planning Centre in Harwich, and also undertake out-of-hours monitoring for our sister General Lighthouse Authorities the Northern Lighthouse Board and Irish Lights.

The marker is located at the end of Trinity Square.
Predating even the 1514 Royal Charter, our charitable duties emphasise training for prospective Merchant Navy officers and care for aged or distressed mariners and their dependants. We also provide grants for many other maritime charities whose objectives align with our own. Today, the charity disperses over £5 million to meet our goals.
This includes providing almshouses for retired mariners and their dependants in Walmer, Kent and sponsoring cadets through the Merchant Navy Scholarship Scheme and the Unlimited Yacht Cadetship. For centuries Trinity House has been an investor in skills and training, to ensure that our nation’s mariners are world class and our maritime industries are successful and sustainable.

With 95% of the UK’s goods coming or leaving by sea, Trinity House’s aids to navigation and support and training for seafarers make it integral to this island nation’s wellbeing.
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.
Our Aids to Navigation
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, such as lighthouses, buoys and lightvessels. Trinity House maintains over 60 lighthouses; these highly visual aids to navigation range from isolated offshore towers exposed to the open sea—such as the Eddystone, Bishop Rock or Longstone lighthouses—to shore-based stations.

Our Vessels
We have been operating in the waters around England, Wales and the Channel Islands since 1741, using purpose-built tonnage equipped to the highest technical standard and manned by professionally qualified officers and crew. Coordinated and monitored around the clock by our Planning Centre, typical vessel activities include wreck location and marking, aid to navigation maintenance, towing, buoy handling and surveying.
Working at sea is unpredictable and inherently hazardous. To preserve the safety of the mariner we take measures to make sure we can respond effectively should an incident occur, working closely with our partners at the Department for Transport and the MCA. We have a vessel ready to respond within six hours of the Dover Strait, carrying our instantly recognisable Emergency Wreck Marking Buoys.

Wrecks and New Dangers
When Trinity House is advised of a wreck or new danger, an immediate assessment of the possible risks to surface navigation is undertaken. Using modern systems to assess the risk—including historical AIS vessel track information and enhanced charting technology—ensures the most appropriate reaction and that the full reasoning behind the decision can be recorded for future consideration.
If it is considered necessary to deploy a Trinity House vessel the 24/7 Planning Centre team will consider the current fleet disposition and task the most appropriate ship to proceed to the location to confirm the exact location of the wreck and ascertain the clearance depth over the danger. This data will then be risk assessed and a decision will be made as to appropriate marking requirements.
Cadet Training
The Trinity House Merchant Navy Scholarship Scheme provides financial support for young people seeking careers as officers in the Merchant Navy. A career at sea in the Merchant Navy is one of the most satisfying and worthwhile occupations it is possible to have. There are excellent career opportunities for young people who can meet the minimum academic requirements and have a practical and enthusiastic approach to life.
Major opportunities include Navigation (Deck) Officer—putting you in control of the ship—or Engineer Officer—operating the mechanical and electrical equipment on the ship—or Electro-Technical Officer—ensuring that a ship’s electronic and electrical equipment is in good working order.
