About us
HMGCC (His Majesty’s Government Communications Centre) is a UK government base for national security engineering, creating the tools and technologies needed to help keep the country safe.
What we do
Using brilliant innovation and technology, HMGCC solves the toughest technical challenges for the national security community. We create, design and test our own technical solutions, as well as working with outside industry and academia, to support national security operations in the UK and across the globe.
National security engineering
HMGCC is made up of hundreds of world-class engineers, technologists and scientists who work with cutting edge equipment to deliver operational technology (OpTech).
We research, innovate and create amazing solutions to help national security and defence remain at the forefront of rapid global advances in technological capabilities.
Our leadership
HMGCC is a government organisation that comes under the ministerial responsibility of the Foreign Secretary.
Our Chief Executive, George Williamson and our deputy directors are responsible for our main work areas and oversee the work of the senior leadership team.
Our story
Founded in 1938, HMGCC has spent more than 80 years as a technological problem-solver for government.
We started life as specialists in overseas bespoke wireless communications, and, during World War 2, computer pioneer Alan Turing worked with us on speech encryption, following his time at nearby Bletchley Park.
Today HMGCC is still coming up with the technology national security needs for its operations, including intelligence gathering and secure communications, but also working across a range of emerging tech areas, not least AI and cyber security.
Championing STEM
We are committed to inspiring future generations of engineers, including underrepresented groups, through activities in education.
We participate in a wide range of events both in our local community and further afield designed to promote and inspire science, technology, engineering and maths.
