Microsoft AI Certification Renewal 2026: The Complete UK Guide

Last updated: May 2026

TL;DR

Microsoft AI role-based certifications (AB-730, AB-731 and AB-100) expire twelve months after you earn them and must be renewed via a free online assessment on Microsoft Learn. Fundamentals certifications (AB-900 and AI-901) do not expire. The renewal assessment is open book, unproctored and takes around 45 minutes. The renewal window opens six months before your expiry date.

Microsoft AI Certification Renewals: What Changed in 2026

If you sat AB-730 (AI Business Professional) or AB-731 (AI Transformation Leader) when they reached general availability in February 2026, your first renewal window opens in August 2026, six months before your certification expires. This is the first time the wider UK cohort of Microsoft AI certificate holders will encounter Microsoft's annual renewal model, even though the model itself has been in place since at least December 2020 [1].

Despite some industry chatter to the contrary, Microsoft did not introduce new renewal mechanics at Ignite 2025. What changed in 2026 is simply that an entirely new family of AI role-based certifications has hit general availability, and the existing annual renewal model now applies to them. This guide explains exactly how renewals work for the current Microsoft AI certification lineup, what UK candidates need to know about the assessment, and what happens if you let a certification lapse.

For broader context on how Microsoft's 2026 certification lineup came together, see our companion piece on the Microsoft AI certification roadmap.

Which Microsoft AI Certifications Require Renewal

Not every Microsoft AI certification expires. The renewal requirement depends on the level of the certification, not on the exam name itself.

The rule is straightforward. Microsoft's official credential expiration policy states that role-based (associate and expert) and specialty certifications expire after one year, while fundamentals certifications do not expire at all [2].

This means anyone who has invested in AB-900 or AI-901 can keep that credential indefinitely with no further action required. If you have earned AB-730, AB-731 or AB-100, however, you will need to plan for an annual renewal assessment for as long as you want to keep the certification active. The AB-100 certification page explicitly sets renewal frequency to 12 months [3].

One important note on AB-900: a small number of early beta exam holders reported seeing an incorrect expiry date in their Microsoft Learn profile shortly after launch. Microsoft confirmed this was a system error and not a policy change. AB-900 remains a fundamentals certification and does not require renewal.

How the Free Microsoft Learn Renewal Assessment Works

The renewal assessment is delivered entirely through Microsoft Learn, with no Pearson VUE booking, no test centre visit and no proctored home session. It is on-demand, so you can take it whenever it suits you during your eligibility window.

Renewals are free. There's no cost to renew your certification, just make sure you pass the online assessment before your certification expires. Fundamentals certifications do not expire.

Practically, this means you sign into your Microsoft Learn profile, navigate to your certifications, and look for a blue Renew button next to the eligible certification [5]. The assessment opens directly in your browser. There are no remote proctoring tools to install, no biometric checks and no scheduled slots to book. You can pause and resume in the same session if you need to, although Microsoft recommends completing it in one sitting.

The assessment is open book. Microsoft does not penalise you for consulting documentation, and the format reflects the reality of how certified professionals work day to day.

The Six-Month Renewal Window Explained

You become eligible to take the renewal assessment exactly six months before your certification's expiry date. The window stays open until your certification actually expires. Microsoft will not let you renew earlier than this six-month boundary, and once the certification expires the renewal route closes permanently [4].

A few timing details that catch UK candidates out:

1. Expiry times are in UTC. During British Summer Time (BST, UTC+1), your local renewal deadline is one hour later than the UTC timestamp shown on your profile. During GMT, they match. If your UTC expiry is one minute past midnight, your effective deadline in the UK can be either that same minute or one hour later depending on the season.
2. Email reminders are opt-in. Microsoft sends renewal reminders to candidates who have agreed to communication terms in their Learn profile. If you opted out of marketing emails when you registered, you may not receive a renewal reminder at all. Set a calendar nudge manually.
3. The window does not extend. If you forget to renew before the expiry date passes, there is no grace period and no extension. We cover what happens next in the lapse section below.

For the AB-730 and AB-731 cohorts who certified at general availability in February 2026, the first renewal windows will open in August 2026. The renewal pages on Microsoft Learn for these specific certifications are not yet live at the time of writing because Microsoft only publishes renewal content once a certification has been generally available for at least six months.

Cost: Free Renewal vs Paying for the Original Exam

The renewal assessment costs nothing. Microsoft is unambiguous on this point.

Is there a cost to renew Microsoft Certifications? No. Certification renewal is free to anyone with a valid Microsoft associate, specialty, and expert certification.

— Microsoft Learn, Renew your Microsoft Certification FAQ (last updated 7 August 2025) [5]

By contrast, the original paid exam carries a real cost. Microsoft's published guidance is that associate and expert exams typically list at US$165, with regional adjustments [6]. The actual GBP price for UK candidates is set by Pearson VUE at checkout and is not published as a static figure on Microsoft Learn. UK candidates may also see 20% VAT added at checkout for digital services. The practical upshot is that letting a certification lapse and then re-sitting the full exam will cost you well over a hundred pounds per attempt, whereas keeping it renewed costs nothing but your time.

If cost is the main reason you are hesitating to certify in the first place, our guide to exam voucher discounts and free exam opportunities covers ways to reduce the original exam fee.

What's Tested: Skill Outline Updates Only

The renewal assessment is significantly narrower than the original exam. Rather than re-testing the full skill outline, it focuses on what has changed since the previous version of the exam.

The renewal assessment is shorter because it focuses only on relevant updates. Renewal assessments take about 45 minutes to complete. Prepare by using the learning modules on the certification's renewal page on Microsoft Learn.

— Microsoft Learn, Renew your Microsoft Certification FAQ (last updated 7 August 2025) [5]

The assessment is aligned with Microsoft's regular exam refresh cadence. When the underlying exam is updated to reflect new product capabilities or skill priorities, the renewal assessment is updated alongside it. This is particularly relevant for the AI certification track, where Microsoft has been moving fast: AB-730 and AB-731 candidates can reasonably expect their first renewal assessment to test new Copilot Studio features, agent capabilities and governance practices that were not yet in scope when they first sat the exam. Our overview of skill-outline changes announced at Microsoft Ignite 2025 details the kinds of updates that tend to flow into renewal assessments first.

Note that Microsoft has also confirmed that some renewal assessment items may have been drafted with the help of AI, but all items are reviewed by subject matter experts before they appear on the assessment.

How to Prepare for Your Renewal Assessment

Because the assessment is open book and focused only on updates, you do not need to repeat the full study programme you used for the original exam. Most UK candidates can prepare adequately in two to four hours of focused review, spread across a week.

A pragmatic preparation plan:

1. Work through the renewal learning path on Microsoft Learn. Each renewing certification has its own dedicated renewal page once it goes live, listing the specific modules that cover the new content. These are short and focused.
2. Review the latest official skills outline. The skills outline for your certification is updated whenever the underlying content changes. Comparing the current version to the one you sat against highlights exactly what to focus on.
3. Skim recent Microsoft Tech Community posts for the products covered by your certification. The community blog often previews changes weeks or months before they show up in the skills outline.
4. Take the renewal assessment with the official documentation open in a second browser tab. Open book is permitted, so set yourself up to look things up quickly. If you have prepared by working through the renewal modules, you will mostly rely on documentation for syntax-level checks rather than core concepts.

Our AB-730 exam preparation guide and AB-731 study plan cover the broader exam scope. For renewal-specific prep, focus only on the delta against your last sitting.

What Happens if Your Microsoft Certification Lapses

If you miss your renewal window, the consequences are significant. There is no grace period.

After the Certification expires, you will no longer be able to renew that Certification and will need to re-earn the Certification by passing all the required exam(s).

— Microsoft Learn, Credential Expiration Policy (last updated 15 July 2024) [2]

Practically, this means three things:

1. You lose active certified status. Your certification will no longer appear as active on your Microsoft Learn profile, on your transcript link that you share with employers, or on your published badge.
2. The free renewal route is gone. You cannot retroactively take the free renewal assessment after the expiry date. The only path to recertification is to sit the full paid exam again through Pearson VUE.
3. You pay the exam fee again. For role-based AI certifications, this is the cost of a full Pearson VUE sitting, plus any VAT, plus the time investment of preparing for the broader exam rather than just the delta.

If your certification has already lapsed, the practical guidance is to revisit our full exam preparation guides and plan a structured study sprint rather than treating it as a quick refresh.

Common Renewal Mistakes UK Candidates Make

Five patterns we see most often when UK candidates attempt their first renewal:

1. Assuming the assessment is short and easy. It is shorter and open book, but the questions cover the most recent updates and can be unexpectedly specific. Plan at least two hours of focused review.
2. Mistaking UTC for local time. A renewal deadline of 00:01 UTC on a Monday is 01:01 BST on that same Monday during British Summer Time, but it remains 00:01 on Monday in GMT. Always treat the UTC timestamp on your profile as the authoritative deadline and renew with at least a few hours to spare.
3. Skipping the renewal learning path. The official renewal page on Microsoft Learn tells you exactly which modules cover the new content. Candidates who go straight into the assessment without working through this path are far more likely to need a retake.
4. Forgetting the 24-hour wait. Microsoft allows an immediate first retry if you fail, but after the second attempt you must wait at least 24 hours before each further attempt [5]. If you fail twice in quick succession and your certification expires the next morning, you may run out of attempts.
5. Renewing too early and finding the page missing. You cannot take the assessment more than six months before expiry. For AB-730 and AB-731 candidates from the February 2026 cohort, the renewal page itself will not be live on Microsoft Learn until August 2026 at the earliest.

FAQ

Do Microsoft AI certifications expire?

Most do. Role-based AI certifications including AB-730 (AI Business Professional), AB-731 (AI Transformation Leader) and AB-100 (Agentic AI Business Solutions Architect) expire twelve months after you earn them and require an annual free renewal assessment on Microsoft Learn. Fundamentals certifications, including AB-900 and AI-901, do not expire.

How much does it cost to renew a Microsoft certification?

Nothing. The renewal assessment is delivered free on Microsoft Learn. You do not need a voucher, you do not book through Pearson VUE, and there is no test-centre fee. By comparison, sitting the original paid exam again costs around US$165 list price plus VAT for UK candidates, with the exact GBP figure shown at Pearson VUE checkout.

How long does the Microsoft renewal assessment take?

Microsoft states that renewal assessments take about 45 minutes to complete. The assessment is shorter than the original exam because it covers only recent updates rather than the full skill outline. Most candidates finish in 30 to 45 minutes, although you can pause and resume within a single session if you need to.

Can I retake the renewal assessment if I fail?

Yes, and there is no overall limit on attempts. If you fail your first attempt, you can retry immediately. After the second failed attempt, Microsoft requires a 24-hour wait between any further attempts. As long as you eventually pass before your certification expiry date, the failed attempts have no consequence.

When can I take the renewal assessment?

The renewal window opens exactly six months before your certification's expiry date and closes at expiry. You cannot take the assessment earlier than six months out, and there is no grace period after expiry. Microsoft calculates expiry in UTC, which matters for UK candidates during British Summer Time when local time runs one hour ahead.

What happens if my Microsoft certification expires?

Once expired, you lose the free renewal route entirely. Your only path to recertification is to sit the full paid exam again through Pearson VUE, which means paying the full exam fee and preparing against the complete skills outline. Your certification will no longer show as active on your transcript and badge.

Ready to Renew or Re-Certify?

Whether you are six months out from your first renewal or you let a certification lapse and need to plan a re-sit, structured practice helps.
