Head of Casework and Assessments

Job summary

The SIA is an executive non-departmental public body sponsored by the Home Office. We were set up in 2004 to regulate certain activities in the private security industry and employ nearly 400 members of staff. We are operationally independent of government.

We are now preparing to take on new responsibilities as the regulator of Martyn’s Law - named after Martyn Hett, one of the 22 people who tragically died on 22 May 2017 in the terrorist attack on Manchester Arena. Martyn’s Law, introduced by the Terrorism (Protection of Premises) Act 2025, is intended to improve protective security and preparedness at premises and events across the UK.

The new Act will require premises in scope to be prepared to keep people safe in the event of an attack. Certain larger premises and events will also need to take steps to reduce their vulnerability to acts of terrorism.

Martyn’s Law is primarily a civil, regulatory regime. We will regulate supportively and proportionately but robustly. The SIA will have new guidance, investigatory and inspection functions and a range of new powers and sanctions. Our new Martyn’s Law functions will sit alongside and complement our existing responsibility for regulating the private security industry.

Job description

Step into a role where your leadership will shape the future of public safety across the UK.

We’re looking for an exceptional Head of Casework and Assessment to lead a critical new function at the heart of the Martyn’s Law regulator.

Your decisions and direction will help ensure compliance, build trust, and raise standards across premises and events nationwide to help keep the public safe.

We’re seeking a confident leader with experience managing complex casework in a regulatory or similarly demanding environment. You’ll bring the ability to make sound, high-stakes decisions, build strong partnerships, and lead teams through change with clarity and purpose. If you’re motivated by purpose, driven by impact, and ready to lead at scale, this is your opportunity to make a difference that truly matters.
