When AI Changes the Subscription

What Is the CMA Investigating?

The CMA opened a consumer protection investigation into Microsoft on 27 July 2026.

The investigation concerns changes made to Microsoft 365 Personal and Family subscriptions, including the addition of new functionality such as Copilot.

According to the CMA, existing customers were given access to new features from January 2025 at no additional cost for the remainder of their existing subscription period.

At renewal, however, customers could face a choice between a plan containing the additional functionality at a higher price and a lower-priced “Classic” plan without those additions.

The CMA is examining whether Microsoft's communications gave customers sufficiently clear information about the plans and the difference in cost before they made a renewal decision.

An Investigation Is Not a Finding

That distinction matters. The commercial lessons for SaaS businesses come from the regulatory questions being examined, rather than from assuming the eventual outcome of the investigation.

Why SaaS Businesses Should Pay Attention

AI Features Are Becoming Part of Subscription Design

The significance of the Microsoft investigation extends beyond one productivity-software subscription.

AI functionality is increasingly being incorporated into established digital products. SaaS providers may introduce assistants, automated analysis, content generation or other AI-driven functionality into a service that customers already use.

That creates an important commercial question: what happens when the enhanced product also becomes the more expensive product?

Businesses should consider how the change is communicated, whether an existing lower-cost product remains available and how customers are told about their options before renewal.

Customer Choice Should Be Designed Into the Journey

Subscription compliance is not simply a matter of having technically correct terms and conditions somewhere on a website.

The customer journey itself matters.

Pricing pages, renewal emails, account dashboards, upgrade notices and cancellation pathways may all affect whether a customer understands what is changing and what alternatives are available.

For SaaS businesses, legal review should therefore extend beyond the subscription contract to the way material information is presented at key decision points.

Terms, Pricing and Product Design Need to Work Together

A SaaS provider introducing significant new functionality should consider whether its existing contractual framework adequately deals with product changes, pricing and renewal.

Depending on the business model, relevant issues may include:

• the contractual right to modify features;
• the contractual mechanism for changing prices;
• notice of changes before renewal;
• automatic renewal arrangements;
• the presentation of alternative plans;
• downgrade and cancellation routes;
• free trials and promotional periods;
• how AI functionality is described to customers; and
• whether marketing claims accurately reflect what each tier provides.

What SaaS Businesses Should Review

• Map the renewal journey: identify what information customers actually see before a subscription renews.
• Compare the plans: make material differences in features and price sufficiently clear.
• Review change clauses: ensure the contractual framework properly addresses changes to functionality and pricing.
• Check AI additions: consider whether introducing AI functionality materially changes the service or commercial proposition.
• Review customer communications: renewal emails and in-product notices should work consistently with the contractual terms.
• Test customer choice: consider whether downgrade, alternative-plan and cancellation options are sufficiently clear in practice.

Key Points

• The CMA investigation into Microsoft opened on 27 July 2026.
• It concerns the presentation of information about changes to Microsoft 365 Personal and Family subscriptions, including the addition of Copilot.
• The CMA is examining whether customers received key information about available plans and differences in cost before making a decision.
• No finding of consumer-law infringement has been made.
• For SaaS businesses, the investigation is a useful reminder that terms, pricing, product design and renewal communications should be considered together.
