According to the statutory instrument published on legislation.gov.uk, the Secretary of State has made the Terrorism (Protection of Premises) Act 2025 (Commencement No. 2) Regulations 2026 under section 37(2)(b) of the parent Act. The instrument was signed on 10 June 2026 by Dan Jarvis, Minister of State at the Home Office. The Regulations bring a limited but important set of provisions into force on 15 June 2026. They activate parts of section 12 on Security Industry Authority guidance and section 18(5) to (7) on a statement about qualifying worldwide revenue.
The section 12 provisions commenced are section 12(2)(a), section 12(2)(b) and section 12(3). The explanatory note says these subsections deal with the Security Industry Authority's duty to produce guidance, secure approval from the Secretary of State, publish that guidance once approved, and keep it under review. One drafting point matters. Section 12(2)(c) is specifically left out of this commencement order, so the whole of section 12 is not yet in force. For legal and compliance teams, that is a clear sign that implementation of the 2025 Act is still being sequenced provision by provision.
The second group of provisions commenced by the Regulations is section 18(5) to (7). As the explanatory note on legislation.gov.uk states, these subsections require the Security Industry Authority to produce a statement on the constitution of qualifying worldwide revenue, publish that statement, and lay it before Parliament. That matters because the Act refers to qualifying worldwide revenue within its wider enforcement structure. Bringing these subsections into force means the regulator can now begin setting out, in a public document and under parliamentary scrutiny, how that revenue concept is to be framed for the purposes of the legislation.
For operators of premises, event organisers and sector advisers, this commencement date is more about regulatory architecture than immediate on-site change. The instrument does not itself create a fresh set of front-line duties on 15 June. Instead, it starts the guidance and publication obligations that will help explain how later parts of the regime are to be administered. That sequence is standard in commencement practice. Before a regulatory scheme can be applied consistently, departments and regulators usually need approved guidance, a settled reporting framework and a clear documentary basis for Parliament and affected organisations.
The explanatory note states that this is the second commencement instrument made under the Terrorism (Protection of Premises) Act 2025. That confirms the Act is being brought into force in stages rather than through a single commencement event, allowing the Home Office and the Security Industry Authority to move from statutory text to operational detail in a controlled order. The note also points readers to the Act's impact assessment, published through Parliament, and says hard copies can be obtained from the Home Office's Protect and Prepare Unit at 2 Marsham Street. For organisations tracking costs and administrative effects, that assessment remains the main published account of the government's expected burden and policy case.
The immediate effect, then, is procedural but still significant. From 15 June 2026, the Security Industry Authority will be under active duties to develop approved guidance and to prepare a published statement on qualifying worldwide revenue that must also be laid before Parliament. For policy professionals, the next practical marker will be publication. Once the guidance and revenue statement appear, regulated organisations will have a firmer basis for compliance planning, internal governance and legal interpretation as further parts of the 2025 Act are commenced.
