Microsoft Copilot is baked into Microsoft 365 from 1 July — what every UK business needs to do before then.

What changes on 1 July 2026

Microsoft announced at Build 2026 that Copilot will move from an optional premium add-on to a core feature of Microsoft 365 Business Standard (£10.30/user/month) and Business Premium (£18.60/user/month) plans. The change takes effect on 1 July. If your business is on either of these plans, Copilot will simply appear in your applications — no upgrade, no separate purchase, no opt-in required.

For businesses on Microsoft 365 Business Basic or standalone Office licences, Copilot remains an optional add-on at this stage. The permanent inclusion is targeted at the mid-tier plans where the majority of UK SMBs are concentrated.

What Copilot can do in your existing tools

The Copilot features landing in standard Microsoft 365 are not experimental — they have been refined through two years of enterprise testing and are genuinely useful for day-to-day business tasks:

• Outlook: Draft email replies in your tone from a brief prompt. Summarise long email threads. Schedule meetings from conversational requests.
• Word: Generate first drafts from bullet-point briefs. Rewrite sections for different audiences. Summarise long documents into executive summaries.
• Excel: Analyse data and surface trends in plain English. Build formulas from a description. Create charts from selected data without manual configuration.
• Teams: Transcribe and summarise meetings automatically. Generate action items from conversations. Answer "what did we agree about X?" after the meeting ends.

The new voice and transcription capabilities

Microsoft Build 2026 also unveiled seven new AI models for voice, transcription, and coding within the Microsoft AI (MAI) family. These ship with the July update and are particularly practical for field-based businesses. You can now dictate a site note, a customer summary, or a quote outline verbally — and have Copilot convert it to a structured document, draft a follow-up email, or update a client record, all without touching a keyboard.

For tradespeople who spend most of their working day on-site with their hands occupied, voice-to-document capability removes one of the largest friction points in running an admin-heavy service business.

What the Work IQ API means for the future

Alongside the Copilot permanent rollout, Microsoft announced the Work IQ API reaching general availability on 16 June. This allows businesses to build custom AI agents that securely access Microsoft 365 data — calendars, emails, documents, customer communications — at scale. For businesses working with IT partners or AIFA, this is the foundation for building custom AI workflows on top of tools you already use.

The practical sequence is: July 1, Copilot lands in your tools. You learn what it does. Where it falls short, custom AI workflows built on Work IQ API fill the gap. This is not a one-time event — it is the beginning of a structured AI integration into the Microsoft stack.
