which means you can achieve the ILM Level 7 Diploma in Leadership and Management alongside the MSc, for no extra work or cost?

This premise is factually incorrect. The OTHM Level 7 Diploma in Strategic Management and Leadership is not designed to run concurrently with an ILM qualification for no extra cost. ILM and OTHM are distinct awarding bodies with separate accreditation, assessment, and fee structures. While both sit at RQF Level 7, they require independent registration, tuition fees, and assessment submissions. No standard provider offers a bundled route where completing the OTHM diploma automatically grants the ILM diploma without additional payment or work. Always verify specific partnership claims directly with the chosen learning provider, as such offers are rare and typically involve significant additional tuition costs rather than being included for free.
