On 2 September 2020 we became FCDO Services. Read more about our name change.
FCDO Services has a rich heritage. We are proud to have evolved and innovated throughout the years to meet the needs of Her Majesty’s Government.
The Queen’s Messengers
The oldest part of FCDO Services dates back to at least 1199, when the records of King John mention the Queen’s Messenger Service. These messengers serve the King or Queen by carrying secret information and deliveries, making sure it arrives safely without being seen by our enemies. Over 800 years later, they still help the UK communicate secretly with people abroad today.
Our Origins and WWII
The true birth of FCDO Services came at the end of the 1930s. The Foreign Office wanted a faster way of sending secret messages, so they could respond to events more quickly. We began as a team of telephone technicians, and our earliest recorded technician was looking after the telephone connections in Rome in 1937.
This all changed in 1938. As the threat of war increased, so did the danger that enemy troops might cut telephone lines. To prevent this, the Foreign Office switched to relying on radio and created a new unit.
A specialist unit of radio technicians, we looked after radio equipment, intercepted enemy communications and developed new technology throughout the Second World War. Ever since, together with the Queen’s Messengers, we have made sure the Foreign Office can send information and deliveries securely.
Our scope grew in 1945, when we began to keep Embassies secure as well as communications. We created new teams who travelled abroad to look after radios, telephones and physical security. For the first time, technicians stayed in the most vulnerable Embassies permanently, to be able to offer the best support.
At the same time, the Foreign Office also wanted to protect their Embassies from being spied on. We set up a team of specialists to dedicated to the challenge. By 1958 the Cabinet Office recognised this team as the national authority on counter-eavesdropping. Known today as UK NACE, they remain the UK experts on preventing and discovering enemy espionage.
1970s – Modern Day
We have always worked to develop and understand cutting edge technology to provide the highest level of security. We still protect communications and Embassies, but today we also use secure IT systems to send or host information. Most recently, becoming a Trading Fund in 2008 has allowed us to expand outside of the Foreign, Commonwealth and Development Office and use our expertise to protect departments across government.
