While the Terrorism (Protection of Premises) Act received royal assent in 2025, many questions remain to be answered in the year ahead. Who, for example, will be responsible for Zone Ex, the transitional space outside venues, accessible by crowds and where they often congregate? As a possible soft target for terrorists, accompanying regulations need to resolve the threat rather than just transfer it from inside the premises to out. We keenly wait to see whether detailed guidance is forthcoming from the Security Industry Authority in 2026 to assist those with control of premises and events that meet the standard and enhanced tier thresholds or whether it will be necessary to wait until 2027. Even with so much still up in the air, it is still never too early for property and liability underwriters to review their proposal forms to make sure they understand the nature of the risks being underwritten.
