At Grant Thornton we’re building something bold. We’re doing things differently – looking to the future, driving ambitious growth and pioneering positive change in our industry. Providing audit, tax and advisory services, we empower clients through strategic insight, curiosity, and genuine partnership. Our journey from great to exceptional is well underway. With significant investment behind us and a clear strategy for growth, there’s real momentum.

Our Public Sector Audit division is at the forefront of delivering trusted, independent assurance to the public sector across the country.

Our team combines deep sector expertise with a proactive approach to emerging challenges, including digital transformation, cyber resilience, and sustainability reporting.

With a commitment to quality and ethical standards, we empower public sector organisations to build confidence with stakeholders and drive positive change.

If you’re an experienced Interim Public Sector Auditor who’s tired of choosing between freedom and meaningful work, there’s another route. Within our Audit team, you’ll be given the opportunity to take on short- to medium-term projects that sharpen your expertise, stretch your thinking, and give you a different angle on familiar challenges - all without locking you into a single path. You can engage with us through your own limited company or on inside IR35 terms – whichever way gives you the freedom you’re looking for.

Skills we are looking for:

• Proven experience in external audit within the NHS or Local Government sector, with a strong understanding of public sector audit requirements, frameworks, and regulations.
• Demonstrated experience operating as an in-charge or team leader, with the ability to manage audit assignments and oversee delivery to deadlines.
• Strong project management skills, with the ability to plan, organise, and prioritise workload effectively across multiple engagements.
• Experience in coaching, mentoring, and supporting junior team members, fostering development and promoting a collaborative team environment.
• Excellent communication and stakeholder management skills, with the ability to build effective working relationships and confidently engage with clients and colleagues at all levels.

Why Consultants choose the ATC:

• Work that moves you forward: When a project fits your skills, we’ll get in touch, but you choose whether it’s right for you. That means working on engagements that genuinely build your portfolio and expand your expertise.
• The freedom of contracting without the hidden admin: You’re not left to navigate the freelance world alone. Our Agile Talent team helps you understand freelance regulation and connects you with people who broaden your thinking through our teams and clients.
• Community you can actually feel: Connection shouldn’t disappear just because you’re contracting. From market insights to wellbeing sessions to networking events, you’ll be part of a community designed to make the independent path less isolated and more impactful.

We have a culture where talented people thrive – where high performance is not just expected but enabled. It’s a culture built on clarity, curiosity, and care. One that challenges us to aim higher, where we’re encouraged to make the most of an abundance of resources to fuel our own development, and where we support each other to grow, learn, and succeed. Our open and accessible culture means you’ll interact with leaders who are interested in you and everything you bring to our firm. The things that set you apart, we value them. That’s why we give you the freedom to bring your whole self to work and pursue your passions inside and outside of work.
