What Is ITIL 5? ITIL Version 5 Explained (2026)

ITIL Version 5, commonly shortened to “ITIL 5”, is the latest edition of the world’s most widely used framework for IT service management. The Foundation level launched on 12 February 2026, with advanced modules rolling out across the rest of the year. PeopleCert is the certification body behind it. If you work in IT operations, service delivery or digital transformation, here is what the new version actually changes, and why you don’t need to wait for it to start building recognised, career-ready skills today.

What is ITIL 5?

ITIL 5 is an evolution of ITIL 4 rather than a wholesale reinvention. Around 40% of the content is carried over from ITIL 4, roughly 36% is genuinely new, and about 24% has been revised. That balance matters: it means the framework you may already know still forms the backbone of the new version, so existing knowledge remains valuable.

Three themes shape the update. The first is AI adoption, reflecting how artificial intelligence now sits inside everyday service management. The second is value-driven delivery, keeping the focus on outcomes for the business rather than activity for its own sake. The third is sustainable and responsible service management, acknowledging that IT decisions carry environmental and ethical weight. These themes run through the whole framework, much as the ITIL guiding principles did in ITIL 4, giving practitioners a consistent lens for decision-making.

The ITIL 5 structure and certifications

ITIL 5 begins with the Foundation qualification. This introduces the core vocabulary, the ITIL Value System, and the Product and Service Lifecycle. It is the entry point everyone starts from, whether you are new to service management or moving across from another discipline.

From there, learners can progress into a set of specialist modules, each focusing on a distinct part of modern service delivery:

ITIL Product
ITIL Service
ITIL Experience
ITIL Strategy
ITIL Transformation

Completing combinations of these modules leads to the higher designations: Managing Professional, Strategic Leader, Practice Manager and, at the top, Master. There is also a dedicated AI Governance extension module, reflecting how central responsible AI use has become to running services well.

What’s different from ITIL 4?

The practical disciplines you rely on day to day are still present, but reframed around the new value system. If your work touches areas such as coordinating deployments, you’ll find that the thinking behind ITIL release management carries forward, now viewed through the product and service lifecycle rather than as a standalone process. Likewise, teams that use ITIL to structure delivery work, an approach explored in our guide to ITIL project management, will recognise the underlying principles even as the terminology is refreshed.

The biggest shift is emphasis. ITIL 5 assumes AI is already part of how services are designed, run and improved, and it asks practitioners to think about sustainability and accountability alongside cost and speed. It is less a new rulebook and more a modernised way of applying the discipline you already understand.

Because so much of the framework is retained, the transition for existing practitioners is designed to be gentle rather than disruptive. Concepts such as value co-creation, the four dimensions of service management and a focus on continual improvement remain central. What changes is the context in which you apply them: automated tooling, machine-assisted decisions and a growing expectation that services are delivered responsibly and sustainably.

How ITIL 4 and ITIL 5 work together

Here is the important part for anyone weighing up when to certify. ITIL 4 and ITIL 5 will run in parallel for at least 12 months. ITIL 4 Foundation remains fully valid and, crucially, acts as a recognised prerequisite that bridges into the ITIL 5 advanced modules. A dedicated Foundation Bridge exists specifically to carry ITIL 4 holders forward.

In plain terms: an ITIL 4 Foundation certificate is not something you’ll have to redo. It is the on-ramp to ITIL 5. That makes it a low-risk, high-value qualification to hold right now, whichever direction your career takes next.

Should you wait for ITIL 5, or start now?

Waiting has a real cost. ITIL 5 Foundation only became available in February 2026, and the advanced modules are still rolling out through the year. If you hold off, you delay the skills, the certificate and the credibility that employers are looking for today.

The smarter move for most people is to start with ITIL 4 Foundation now. It is available immediately, it is a respected qualification in its own right, and it officially bridges into ITIL 5 when you are ready to progress. You gain a recognised credential today and keep a clear, sanctioned path into Version 5 open for later.

It is also worth remembering that employers hire against the skills that exist today, not against a version number. An ITIL 4 Foundation certificate demonstrates that you understand service management principles and can speak the shared language of IT teams. When ITIL 5 becomes the norm in your organisation, you’ll already have the grounding to build on it, rather than starting from scratch.

Key takeaways

ITIL 5 is a considered evolution of ITIL 4, built around AI adoption, value-driven delivery and responsible service management. It keeps a large share of the framework you may already know, introduces a clear Foundation-to-Master progression, and adds an AI Governance module for the way services are run today. Because ITIL 4 Foundation stays valid and bridges directly into the new version, there is no reason to wait: certify now, and step up to ITIL 5 on your own timeline.
