UK Hydrographic Office (UKHO)

The UK Hydro-graphic Office (UKHO) is dedicated to supporting safe, secure, and thriving oceans. In a rapidly evolving world, our oceans face increasing pressures due to technological advancements, busier maritime traffic, and urgent environmental challenges. The UKHO's team of experts provides hydro-graphic understanding to inform maritime decisions, supporting safe navigation from ship to shore across the globe.

The UKHO's mission is to provide hydro-graphic understanding that enables partners and mariners to navigate the world's oceans in safer and more sustainable ways. For over 200 years, the UKHO's global portfolio of ADMIRALTY charts, publications, and digital services have been trusted by mariners and shipping companies for safe, compliant, and efficient navigation.

As the Primary Charting Authority for 63 coastal states, the UKHO plays a crucial role in hydrography. By engaging with partners worldwide, the UKHO supports nations in managing their marine spaces safely, efficiently, and effectively.

The UKHO's governance body is responsible for providing hydro-graphic data and advice as part of its public task to fulfil its Safety Of Life At Sea (SOLAS) obligations. This supports safe passage in UK waters and other primary charting areas.

The organisation's values serve as guiding principles, helping the UKHO work towards its goals. The UKHO is committed to fostering an environment where its people and organisation can thrive, enabling it to deliver on its vision.
