Microsoft Copilot vs Google Gemini for Business

AET Editorial25 July 2026 2 min read

The enterprise AI assistant battle

Microsoft Copilot and Google Gemini are the two dominant AI assistants vying for enterprise adoption in 2026. Both promise to transform productivity, but they take different approaches and suit different organisations.

Microsoft Copilot

Strengths


  • Deep Microsoft 365 integration — works seamlessly within Word, Excel, PowerPoint, Outlook and Teams

  • Enterprise data security — leverages Microsoft's existing security and compliance framework

  • Familiar interface — employees already in the Microsoft ecosystem face a gentler learning curve

  • Strong partner network — extensive UK partner network for deployment and training

    • Considerations


  • Requires Microsoft 365 E3/E5 licensing

  • Performance varies significantly across applications

  • Can be expensive at scale (£24/user/month on top of M365)

    • Google Gemini

    Strengths


  • Superior reasoning — Gemini Ultra consistently outperforms on complex analytical tasks

  • Google Workspace integration — native in Gmail, Docs, Sheets and Meet

  • Competitive pricing — included in several Workspace tiers

  • Multimodal capabilities — stronger image and video understanding

    • Considerations


  • Smaller enterprise partner ecosystem in the UK

  • Less mature enterprise deployment tooling

  • Workspace has lower enterprise market share than Microsoft 365 in the UK

    • Which should you choose?

    The answer depends on your existing technology stack:

  • Microsoft-first organisations should start with Copilot. The integration advantages are significant, and the UK has excellent Copilot training providers like Infinity Group, Transparity and Cloud Direct.

  • Google Workspace organisations should explore Gemini. Providers like Jellyfish specialise in Google AI adoption.

  • Hybrid environments may benefit from piloting both and comparing results in specific use cases.

    • Training is the differentiator

    Regardless of which platform you choose, the biggest determinant of ROI is how well your employees are trained to use it. Our directory lists specialist training providers for both Microsoft and Google AI tools — investing in proper training typically delivers 3-5x the ROI of the technology investment alone.
