Microsoft’s bundle faces UK scrutiny. Would more choice cut the bill?

Choosing a rival application can mean paying for functionality already included in a Microsoft bundle. That is a switching barrier the UK Competition and Markets Authority identifies, according to The Register: customers adopting alternatives may duplicate licensing costs rather than replace an existing bill. [3]

On October 16, the CMA proposed designating Microsoft’s business-software ecosystem with strategic market status, a regulatory designation that could open the way to targeted competition measures. This is a provisional decision, not an order to break up bundles or an immediate change to customers’ contracts. [2] [1]

For a workplace buyer, the useful question is therefore bigger than whether another product is available. Can it replace part of the existing spend without making the whole setup harder or more expensive to operate? That puts subscription prices, switching work and ongoing integration on the same budget, rather than treating additional choice as an automatic saving.

The regulator’s indicative roadmap identifies software bundling and easier integration of developers’ products as areas for further investigation and possible action. It also asks whether rivals can compete fairly with Copilot, whether security-product bundles limit choice and whether customers can choose which cloud hosts their software licences. [1]

Imagine, hypothetically, a public-service IT team considering a rival security tool. If it must retain the same Microsoft bundle, the rival subscription could become an extra expense. If a future measure permits a genuine substitution, the team might redirect existing spending instead. But any licence saving still has to cover migration, staff training and the work of connecting systems.

That distinction also matters to competing security, AI and cloud suppliers. Removing a barrier could let them compete for budgets already committed to Microsoft, rather than only for new spending. The possible second-order benefit is stronger pressure to improve products or prices. Neither a proposed designation nor more suppliers alone establishes that customers will pay less.

The Register reports that the CMA’s proposal describes Microsoft’s integrated software environment as offering easier technical integration and discounted pricing when applications are bought together. [3]

Microsoft disputes the CMA’s proposed assessment. In a statement to The Register, the company said its products, including Copilot, are open and interoperable, allowing customers to combine them with competing services and choose solutions at attractive prices. [3]

The strongest counterargument is that bundling delivers real integration value and discounts, rather than merely obstructing rivals. If buyers who mix suppliers face higher total costs for comparable functionality, the case that greater choice delivers savings weakens. An intervention could otherwise shift a bill from licences to IT labour without reducing it.

The investigation began on May 14; the new step is the proposed designation. Comments close on November 13, 2026, and the CMA will make its final decision by February 13, 2027. The regulator stresses that strategic market status does not assume wrongdoing. [2] [1]

Watch the final designation decision and, if designation follows, specific conduct requirements or other measures—not simply another statement of intent. The economic test is the cost of comparable working software: licences plus migration, integration and support. Lower standalone prices without a lower full bill would be a narrower win than the headline suggests.
