Interim HR Consultant - Public Sector

Interim HR Transformation Consultant (Public Sector)

Who we are

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. And we empower our people with real opportunity. 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 Agile Talent Community (ATC) brings together experienced contract professionals who want choice without losing connection. You work where you add the most value, alongside teams who treat you as a partner rather than a placeholder.

Joining us in Public Services Consulting

Grant Thornton’s public sector consulting, with a focus on local government, supports councils and public bodies in delivering major programmes, interpreting policy, and designing effective interventions. The team provides expertise in programme and project management, business support, and grant management, helping local authorities achieve strategic objectives, manage resources, and drive positive outcomes for communities. Their approach is tailored to the unique needs of local government, ensuring practical solutions and delivery confidence.

If you’re an experienced Interim HR Transformation Consultant who’s tired of choosing between freedom and meaningful work, there’s another route. Within our Public sector consulting 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 the public sector (local government, central government or healthcare), ideally within Human Resources, People Transformation, or Change Management projects.
• Demonstrable understanding of public sector operations, current policies, and sector-specific challenges.
• Experience delivering or supporting major transformation or restructuring programmes across large or complex organisations.
• Consulting experience (internal or external) is highly desirable.
• Demonstrated ability to provide insightful advice, analysis, or recommendations to stakeholders, clients, or senior leaders.
• Ability to build, maintain, and influence trusted working relationships with colleagues, clients, and key stakeholders.

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.

Our culture and values

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.
