UK Telecoms Security Act Code Updated Amidst Rising Cyber Threats

On June 5, 2026, the UK government announced updates to the Telecommunications Security Act (TSA) Code of Practice, marking its first revision since implementation. The changes, influenced by techUK and the Telecoms Security and Diversification Working Group, aim to enhance the resilience of UK communications networks. Key modifications include a shift from mandatory monthly equipment restarts to a risk-based approach, and the removal of certain intrusive measures. The revised Code will be laid in Parliament for 40 days before taking effect. Telecoms Minister Liz Lloyd also announced plans to strengthen protections for subsea cables, crucial for international data transmission, including tougher penalties for damage to this infrastructure. These updates are seen as vital for maintaining national security and economic stability.

Key Points: • The TSA Code of Practice has been updated for the first time since its inception. • Key changes include a risk-based approach to network equipment management. • New measures will enhance protections for subsea cables critical to data transmission.
