Audit Internship Programme (Summer 2026) - Milton Keynes in High Wycombe

At Grant Thornton we do 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, an inclusive culture and work life balance.

More than a summer internship. This is where your future begins. Auditors are investigators, problem-solvers, and trusted advisers. They dive deep into how businesses operate, ensuring the numbers tell the real story and helping organisations stay on track. Think of it as a backstage pass to the business world - where you don’t just observe, you make a difference.

Our six-week audit summer internship is your launchpad to a meaningful career with a chance to secure a permanent graduate job, a professional qualification, and the opportunity to make a real impact. The internship programme will run for six weeks between 29 June – 7 August 2026. You must be available for the full duration of the internship.

What You’ll Do

• Kickstart your career with a six-week internship that goes beyond the ordinary, with real projects, cutting-edge digital tools, and structured learning designed to make you stand out.
• Your internship kicks off with an action-packed launch conference – a high-energy start that connects you with industry leaders, ambitious peers, and opportunities that set the tone for an unforgettable experience.
• Gain real-world audit experience: Work on live projects, visit client sites, and use digital tools to uncover insights that drive real outcomes.
• Get hands-on learning: Complete real training modules and interactive professional skills workshops across technical and soft skills, supported by feedback to boost your confidence and capability.
• Be part of a real team: Collaborate on a national group project that ends with a presentation to an expert panel – a chance to show off what you’ve discovered during your time with us.
• Build your network: Set yourself up for success by developing relationships with experts, peers and leaders across the firm – plus, making valuable connections with the wider intern cohort that last beyond the programme.

This is a paid internship, so you’ll be fully supported by us while you focus on fully immersing yourself in our culture. And if you perform well during the six-week programme, you could secure a graduate role with us before you begin your final year of study – starting your career already one step ahead.
