Microsoft's June Licensing Shake-Up: What UK SMEs Must Know Before July 1

A Mansfield accountancy firm we work with opened its renewal quote last month and found the figure had jumped by nearly a fifth. Nothing about how they used Microsoft 365 had changed. No extra staff, no new features switched on. The price had simply moved, and the licence they had relied on for three years was being repackaged into something with a different name and a different cost.

They are not alone. The June 2026 round of Microsoft 365 changes is one of the broader reshuffles the platform has seen in recent years, and the deadline that matters for most UK SMEs is 1 July. After that date, several older subscription terms expire, new list prices apply, and a few features become locked behind licence tiers that smaller businesses rarely buy.

This is not a reason to panic, but it is a reason to plan. Here is what is actually changing, in plain English, and what you should be doing with your IT partner before the deadline arrives.

What's actually changing

Three shifts sit at the centre of this update, and they affect businesses in different ways depending on how you currently buy your licences.

1. New list prices across the M365 range

Microsoft has revised the published prices for its Business and Enterprise plans. The increases are not uniform — some plans move more than others — but the direction of travel is upward. If you renew on or after 1 July, you renew at the new rate.

The practical effect depends on your commitment term. Businesses on an annual commitment that locks in before the deadline keep their current pricing until that term ends. Businesses on monthly billing, or those whose annual term happens to renew in July or later, feel the change immediately.

This is the single biggest cause of the bill shock we are warning about. A firm with 40 users can see a meaningful annual difference, and because it lands quietly inside a renewal invoice rather than as a separate announcement, it often goes unnoticed until the direct debit clears.

2. The Copilot subscription transition

Copilot — Microsoft's AI assistant that sits inside Word, Excel, Outlook and Teams — has been sold as a per-user add-on. That add-on is being moved onto a new subscription structure, and the way existing Copilot customers are billed is changing as part of the June update.

If you already pay for Copilot, your subscription does not simply continue on the old terms. It transitions, and during that transition the price and the commitment options can both shift. Some businesses that signed up on promotional or early-adopter terms will find those terms do not carry over.

The risk here is twofold. First, a cost you budgeted for at one figure arrives at another. Second, if the transition is not handled cleanly, you can end up with a gap in service or, worse, paying for two overlapping subscriptions while the old and new arrangements sort themselves out.

3. The E5 prerequisite for Agent 365

This is the change most likely to catch out ambitious SMEs. Agent 365 — Microsoft's framework for building and running AI agents that automate tasks across your systems — now requires a Microsoft 365 E5 licence as a prerequisite.

E5 is the top enterprise tier. It is considerably more expensive than the Business Premium plan that most UK SMEs run on, and it bundles in advanced security and compliance tools that smaller firms often do not need.

If you have been planning to experiment with AI agents — and a lot of SMEs have — this requirement changes the maths. You cannot simply add Agent 365 to your existing Business Premium subscription. You need to either move the relevant users to E5 or rethink the project. For a handful of users this may be affordable. For a whole team it is a different conversation entirely.

Why the 1 July date matters

The deadline is not arbitrary. It is the point at which the old pricing and the old subscription terms stop being available for new commitments. Renew before it and you can, in many cases, lock in current pricing for another year. Let your term lapse into July and you renew on the new terms by default.

This creates a genuine window of opportunity. A business whose annual term ends in August might be able to renew early, before the deadline, and hold its current rate for another twelve months. Whether that is the right move depends on your circumstances, which is exactly why this is a conversation to have now rather than in late June.

What UK SMEs should do before the deadline

Find out your renewal date and billing term

Start here. Many business owners genuinely do not know whether they are on monthly or annual billing, or when their term renews. Your IT partner can confirm both in minutes. Everything else depends on this information.

Audit who actually uses what

Licensing changes are a good prompt to clean house. We routinely find businesses paying for licences assigned to people who left months ago, or for premium plans on users who only ever open email. Trimming dormant and over-specified licences can offset some of the price increase before it even lands.

Model the new costs honestly

Ask your partner for a side-by-side comparison: what you pay now, and what you will pay after 1 July under each option. Seeing the real numbers removes the guesswork and stops a nasty surprise on the next invoice.

Decide on Copilot deliberately

If you use Copilot, understand exactly how your subscription transitions and what it will cost afterwards. If you have been thinking about adopting it, factor the new pricing into that decision rather than the old. Copilot can earn its keep, but only where it is matched to genuine, repeated tasks rather than bought on enthusiasm.

Pause before committing to E5 for Agent 365

If AI agents are on your roadmap, treat the E5 requirement as a planning input, not a blocker. You may be able to license only the users who need it. You may decide the project waits. What you should not do is discover the requirement halfway through a rollout.

Consider renewing early

Where your term renews shortly after the deadline, an early renewal could protect your current pricing for another year. This is not always the best choice — it depends on whether you expect to grow, shrink or change plans — but it deserves a proper look.

The bottom line

The June 2026 changes are not a crisis, but they are a deadline, and deadlines reward the prepared. The businesses that get caught out are the ones who treat their Microsoft renewal as a quiet annual formality. The ones who come out ahead are those who spend an hour with their IT partner before July, check their dates, trim their licences and choose their plan on purpose.

If you are not sure where your subscription stands, get in touch. We will pull up your current licensing, show you what 1 July means for your bill, and help you decide on the right move while there is still time to make it.
