As Microsoft pushes Copilot deeper into Microsoft 365, owners and managers of small and medium-sized businesses face a confusing licensing landscape, shifting product names and price rises taking effect on 1 July 2026. Here is what has changed, what is on offer now, and the controls every administrator should understand.
For most UK small and medium-sized businesses, Microsoft 365 has quietly become the backbone of daily operations: email in Outlook, files in SharePoint and OneDrive, meetings in Teams, and documents in Word, Excel and PowerPoint. Over the past three years, Microsoft has been layering an artificial intelligence assistant — Copilot — on top of that stack. What started as a single premium add-on has fragmented into a confusing patchwork of free tiers, paid tiers, bundles and admin controls. And the rules keep changing.
With significant pricing changes due on 1 July 2026, a new SME-friendly licence already on the shelves, and free Copilot features being pulled from Office apps for unlicensed users at larger firms, now is the moment for business owners to take stock.
A short history of moving goalposts
Microsoft 365 Copilot was first unveiled in March 2023 as a glimpse of “AI for work”. When it became generally available on 1 November 2023, the terms were eye-watering for smaller firms: a substantial per-user add-on on top of an existing Microsoft 365 Enterprise licence, with a minimum commitment of 300 seats. The Register reported at the time that small businesses “need not apply”.
That barrier did not last long. In January 2024, Microsoft removed the 300-seat minimum and extended eligibility to Office 365 E3 and E5 customers. At the same time, the company launched Copilot Pro for individuals and began folding its various AI products — including the old Bing Chat and Bing Chat Enterprise — under the single “Copilot” brand.
A further rebrand arrived in January 2025: the work-account version of Microsoft Copilot, previously known as Bing Chat Enterprise, was renamed Microsoft 365 Copilot Chat and positioned as a free “freemium” entry point for any user signed in with an Entra ID. The branding distinction was, and remains, easy to miss — the free product (Microsoft 365 Copilot Chat) is not the same as the paid product (Microsoft 365 Copilot), and neither is the same as the consumer Copilot Pro or the older “Microsoft 365 Chat” feature.
Through 2025, Microsoft kept tinkering. Role-based products such as Copilot for Sales, Service and Finance were retired and folded into the main Microsoft 365 Copilot licence at no extra cost. The “messages” consumption unit for autonomous agents was rebranded as “credits”. The Microsoft 365 desktop app itself was renamed to the “Microsoft 365 Copilot app”, regardless of whether the user actually had a Copilot licence.
The most significant shift for SMEs came on 1 December 2025 with the launch of Microsoft 365 Copilot Business, a new SKU aimed squarely at companies with fewer than 300 users.
Where things stand in 2026
There are four Copilot options UK SMEs are likely to encounter:
1. Microsoft 365 Copilot Chat (free) — included with any qualifying Microsoft 365 subscription, including Business Basic, Business Standard, Business Premium and Enterprise E3/E5. Users sign in with their work account, get web-grounded AI chat, can upload files into the chat session, and benefit from Microsoft’s “enterprise data protection” promise that prompts and responses are not used to train Microsoft’s foundation models. Crucially, without a Microsoft 365 Copilot licence, Copilot Chat is not generally grounded in Microsoft Graph work data. It cannot act as a tenant-wide search assistant over SharePoint, OneDrive, Teams chats and broader Microsoft Graph work data in the way paid Copilot can, although Outlook has a limited exception for inbox, calendar and meeting prompts, users can upload files into chat, and administrators can enable some metered agent experiences.
2. Microsoft 365 Copilot Business (paid, SMB) — launched December 2025 for businesses with up to 300 users. It requires a qualifying base licence (Business Basic, Standard, Premium, or Apps for Business). This product gives you the full Copilot experience embedded in Word, Excel, PowerPoint, Outlook, Teams and OneNote, grounded in your own work data. Promotional pricing is available for the first year of an annual commitment, running until 30 June 2026.
3. Microsoft 365 Copilot (paid, Enterprise) — the original add-on for organisations on Enterprise E3/E5 or Office 365 E3/E5, or for SMBs that exceed the 300-user cap. Functionally near-identical to Copilot Business but aimed at larger tenants with more advanced governance needs.
4. Microsoft 365 Premium / consumer Copilot features — consumer Microsoft 365 subscriptions may include Copilot features for personal Microsoft accounts (Microsoft launched Microsoft 365 Premium in October 2025 and said it would no longer sell the standalone Copilot Pro add-on), but they are not a substitute for Microsoft 365 Copilot in a business tenant.
The paid versions are the only ones designed to combine work data across Microsoft 365 — SharePoint, OneDrive, Teams, Outlook, meetings and calendar — under the user’s existing permissions. That work-grounded intelligence is what most people picture when they hear “Copilot” — and it is what costs the money.
The April 2026 squeeze and July 2026 price rises
Two recent changes deserve careful attention.
The 15 April 2026 in-app restriction. According to Microsoft 365 Message Center notices and subsequent trade coverage, Microsoft has begun removing the free Copilot Chat experience from inside Word, Excel, PowerPoint and OneNote for unlicensed users at organisations with more than 2,000 Microsoft 365 seats. Most UK SMEs sit comfortably below that threshold and are unaffected, but the direction of travel is clear. Unlicensed users can still reach Copilot Chat via the standalone Microsoft 365 Copilot app and the web, and Copilot in Outlook (for inbox and calendar assistance) remains available without a paid licence. The shift signals that Microsoft views in-app Copilot as a premium feature, not a free perk.
The 1 July 2026 price increases. Microsoft has confirmed price rises for Business Basic, Business Standard, Enterprise E3 and Enterprise E5. Microsoft 365 Business Premium pricing is not changing. Microsoft says the changes reflect new capabilities being added across the suites. For Business plans, these additions are relatively modest: extra mailbox capacity, Copilot Chat enhancements and analytics, with URL time-of-click protection added to Business Basic and Standard. The larger Defender and Intune bundling additions are mainly applied to the Enterprise suites such as Microsoft 365 E3 and E5. UK customers will see the increases applied in sterling on renewal, with the exact figure influenced by the exchange rate on the day.
A second, quieter change followed in May 2026 for CSP subscriptions: Microsoft began enforcing Extended Service Terms on 4 May, replacing the old free buffer period after non-renewal with a paid month-to-month continuation option for eligible subscriptions. In practical terms, missing a renewal date now actively costs money rather than triggering a soft warning.
The practical upshot for owners and managers: Business Premium is now arguably the best-value tier for many SMEs in the SME range, because its price is unchanged while it gains additional bundled benefits. Anyone on Business Basic or Standard adding Copilot needs to factor in not just the per-seat cost of the AI add-on, but also a base-licence price rise on top.
The technical controls every administrator should know
Whether an SME chooses to roll out Copilot Business, stay on the free Copilot Chat, or block the lot, Microsoft does provide meaningful controls. They sit at four layers.
License layer. The simplest control. Copilot Business and Microsoft 365 Copilot are per-user add-ons assigned in the Microsoft 365 admin centre under Users → Active users. Group-based licensing via Entra ID lets you provision and deprovision Copilot at scale without touching individual accounts. Removing the licence fully removes paid Copilot from all apps for that user.
Tenant and app layer. In the Microsoft 365 admin centre under Settings → Integrated apps, administrators can find the Copilot app and either block it tenant-wide or scope it to specific users or groups. Blocking here disables Copilot in the Microsoft 365 Copilot app, Teams, Outlook and the Copilot Chat web experience for selected users. The Microsoft 365 admin centre also exposes a Copilot Control System with policies such as Allow web search in Copilot, which can be turned on or off for the whole tenant or specific groups. Teams meeting Copilot is governed separately in the Teams admin centre via meeting policies.
Data layer (the most important for risk). Paid Copilot honours existing SharePoint, OneDrive and Teams permissions — but that is precisely the problem. Copilot does not create access; it reveals access that was already there. A loosely permissioned SharePoint site or an “anyone with the link” OneDrive folder becomes much more discoverable when an AI can summarise its contents on demand. Microsoft’s own guidance is to fix permissions before enabling Copilot, not after. Tools available:
- SharePoint Restricted Content Discovery lets administrators exempt specific sites from Copilot indexing.
- Restricted SharePoint Search can limit Copilot to a defined allow-list of sites while permissions are remediated.
- Microsoft Purview Data Security Posture Management (DSPM) for AI runs data risk assessments and now supports bulk remediation of overshared SharePoint links.
- Sensitivity labels applied via Microsoft Purview Information Protection can encrypt content and deny the “extract” right, which prevents Copilot from reading the file at all.
- Container sensitivity labels applied at SharePoint site and Microsoft 365 Group creation enforce sharing defaults before users get a chance to over-share.
- Microsoft Purview Data Loss Prevention (DLP) for Copilot can either inspect the user’s prompt for sensitive information types, or block Copilot from using files and emails carrying certain sensitivity labels in its responses. These policies require the appropriate Purview role and licensing.
- Audit logs for Copilot interactions are captured in Purview and can be retained for compliance and review.
Endpoint and identity layer. Conditional Access in Microsoft Entra can require multi-factor authentication, device compliance or healthy sign-in risk before a user reaches Copilot. Endpoint DLP on Windows devices onboarded to Purview can warn or block users from pasting sensitive content into third-party generative AI sites in the browser. Intune and Group Policy can hide the Windows Copilot taskbar button and prevent automatic installation of the standalone Copilot app, although Microsoft has been candid that these endpoint controls remove the visible affordance rather than guaranteeing the app cannot run.
Most of the meaningful Purview controls require Microsoft 365 Business Premium or Enterprise E3/E5 plus, in some cases, the Purview Suite add-on. SMEs on Business Basic or Standard will find their governance options noticeably thinner.
What SME owners and managers should do now
Three practical steps stand out:
First, audit before you enable. Anyone considering paid Copilot should commission a permissions review of SharePoint, OneDrive and Teams beforehand. The widespread industry consensus, including in Microsoft’s own deployment guidance, is that the order should be permissions cleanup, then sensitivity labels, then DLP tuning, then Copilot enablement — not the other way around.
Second, model the real cost. Adding Copilot Business is rarely the whole story. Factor in the July 2026 base licence increase, the value of upgrading from Business Standard to Business Premium for the governance tools, and (where relevant) the Purview Suite add-on. The all-in cost can comfortably double a user’s monthly Microsoft spend.
Third, decide on a position for the free tier. Microsoft 365 Copilot Chat is already available to every user with a work account, whether the business has formally adopted AI or not. Doing nothing is itself a decision. Administrators should either explicitly allow Copilot Chat (and educate staff on what should and should not be pasted into it), or actively scope and block it via the Integrated Apps controls.
Microsoft’s direction is unmistakable: AI is being moved from a paid add-on into the fabric of Microsoft 365, with a clearer paywall between casual use and deep, work-grounded productivity. For UK SMEs, the next six months are the window to get base licences, governance and rollout plans in order — before the price rises land on 1 July 2026.
