London
Nova South, in Victoria, London, is home to the National Cyber Security Centre (NCSC) – part of GCHQ
The NCSC was established in 2016 with the mission to make the UK the safest place to live and work online, and turns 10 years old in 2026.
Staff at the NCSC work at our sites across the UK, but call Nova South their headquarters, offering cyber security support to our critical national infrastructure, the wider public sector as well as industry, SMEs and the general public to help everyone stay safe online.
Working in the capital allows our people to work closely with key intelligence partners like MI5 and SIS, as well as government, law enforcement and academia.
We’ve always maintained a presence in London. Until recently, we occupied a building on Palmer Street, where we secretly resided for 66 years.
