Lead Assessor - Martyn’s Law Regulator

Job description

The SIA is an executive non‑departmental public body sponsored by the Home Office, set up in 2004 to regulate certain activities in the private security industry.

Currently, we 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.

We’re looking for an experienced regulatory professional who combines strong analytical skills with sound judgement, leadership capability, and a passion for improving compliance outcomes.

In this role, you’ll lead the assessment of complex and high‑risk cases, provide expert advice on protective security and regulatory compliance, and help develop the systems, processes, and people that underpin a high‑performing assessment function.

You’ll oversee assessment prioritisation, manage complex casework from initial review through to final determination, and ensure evidence‑based decisions are delivered consistently, transparently, and efficiently.

Working closely with regulated premises, industry stakeholders, inspectors, and internal colleagues, you’ll play a key role in identifying emerging risks, driving continuous improvement, and embedding best practice across the organisation.

As a recognised subject‑matter expert, you’ll also help shape regulatory policy and operational delivery, providing guidance, mentoring colleagues, and building capability across the wider team.

Why join us?

This is more than a compliance role.

It’s an opportunity to influence a nationally significant regulatory regime, help organisations improve their security posture, and contribute directly to protecting the public.

You’ll work on complex, meaningful issues while helping shape how a new and evolving regulatory function operates for years to come.
