Microsoft 365 vs Google Workspace: UK SME Comparison Guide 2026

The Big Decision: Choosing Your Cloud Productivity Platform in 2026

For UK SMEs, the choice between Microsoft 365 and Google Workspace is one of the most consequential IT decisions you'll make this year. Both platforms have matured significantly, both offer compelling features, and both will cost you real money — so getting this wrong isn't just inconvenient, it's expensive.

This guide cuts through the marketing noise to give you a practical, honest comparison based on what actually matters to UK business decision-makers in 2026.

Pricing: What You'll Actually Pay

Microsoft 365 Pricing for UK Business

Microsoft 365 pricing in the UK currently runs across several tiers:

• Microsoft 365 Business Basic — from £4.90 per user/month (web and mobile apps, Teams, Exchange)
• Microsoft 365 Business Standard — from £10.30 per user/month (full desktop apps included)
• Microsoft 365 Business Premium — from £18.60 per user/month (adds advanced security and device management)

For most SMEs with 10–50 users, Business Standard is the sweet spot. You get the full Office desktop suite — Word, Excel, PowerPoint — plus Teams, SharePoint, and 1TB of OneDrive storage per user.

Google Workspace Pricing

Google Workspace tiers for UK businesses look like this:

• Business Starter — approximately £4.60 per user/month (30GB pooled storage)
• Business Standard — approximately £9.20 per user/month (2TB pooled storage, recorded Meet calls)
• Business Plus — approximately £15.40 per user/month (enhanced security, eDiscovery)

On paper, Google comes in slightly cheaper at comparable tiers. However, factor in any costs for transitioning staff away from Microsoft Office habits and the calculation can shift.

Features and Day-to-Day Usability

Where Microsoft 365 Leads

Microsoft's biggest advantage is desktop application depth. If your business relies on complex Excel models, advanced Word formatting, or PowerPoint presentations with precise design requirements, there's simply no contest. Google Sheets and Docs are capable, but they don't match Excel and Word at the professional end of the spectrum.

Microsoft 365 also wins on:

• Outlook — still the gold standard for email management in professional services, legal, and finance
• Teams — deeply integrated with the wider Microsoft ecosystem, including phone systems via Teams Voice
• SharePoint and OneDrive — mature, flexible document management for businesses that need granular permissions
• Compliance and governance tools — particularly important for UK businesses operating under FCA, GDPR, or ISO 27001 frameworks

Where Google Workspace Leads

Google Workspace's strengths lie in simplicity, collaboration speed, and browser-first working. If your team is younger, already lives in a browser, or works heavily with external collaborators, Google can feel more intuitive day-to-day.

Key Google advantages:

• Real-time collaboration — multiple users editing simultaneously with no version conflict headaches
• Google Meet — straightforward, no-install video conferencing that works reliably
• Gmail — excellent search, clean interface, and strong spam filtering
• Google Drive — simple, fast, and accessible from any device without configuration
• AI integration — Google's Gemini AI tools are increasingly embedded across Workspace at no significant extra cost

It's worth noting that Microsoft's Copilot AI is also rolling into 365, though meaningful AI features at SME pricing tiers are still maturing.

Security and Compliance: A UK-Specific Consideration

For UK SMEs, particularly those handling sensitive client data, operating in regulated industries, or working towards Cyber Essentials certification, security capability matters enormously.

Microsoft 365 Business Premium includes Microsoft Defender, Intune device management, Azure AD Premium, and advanced data loss prevention — making it one of the most comprehensive security packages available at the SME price point. At Coreitech, we frequently recommend Business Premium to clients in professional services, healthcare, and finance precisely because of this security depth.

Google Workspace is no slouch on security — it includes strong baseline protections, endpoint management, and solid admin controls — but for businesses with specific UK regulatory obligations, Microsoft's compliance tooling is generally more mature and better documented.

Migration: What the Transition Actually Looks Like

This is where many comparison guides go quiet, so let's be direct.

Migrating to Microsoft 365 from a legacy on-premise Exchange or file server environment is well-trodden territory. The tooling is mature, the process is documented, and most IT support partners have done it dozens of times.

Migrating to Google Workspace from Microsoft typically involves more change management. Staff need retraining on new apps, and any business-critical processes built around Excel macros, Outlook rules, or Word templates will need reviewing. That's not a dealbreaker, but it's a real cost to factor in.

Migrating between the two platforms — in either direction — is manageable but should always be planned properly. A rushed migration causes data loss risks, productivity dips, and frustrated staff.

Which Platform Is Right for Your Business?

Here's a practical framework for UK SMEs:

Choose Microsoft 365 if:

• Your team uses Word, Excel, or Outlook extensively
• You operate in a regulated sector (finance, legal, healthcare)
• You need robust device management and security controls
• You have an on-premise legacy environment to migrate from
• You want a single vendor for email, collaboration, and telephony via Teams Voice

Choose Google Workspace if:

• Your team is browser-native and mobile-first
• You prioritise simplicity and fast onboarding for new staff
• You have a lean IT budget and don't need advanced desktop apps
• You work heavily with external partners who already use Google
• You're a startup or early-stage business building without legacy systems

For the majority of established UK SMEs we work with, Microsoft 365 Business Standard or Premium remains the default recommendation — primarily because it meets staff where they already are and offers the compliance depth UK businesses need.

Don't Make This Decision in Isolation

The platform choice is only part of the picture. How it's configured, secured, and maintained determines whether you get the value you're paying for. A poorly configured Microsoft 365 tenancy with weak security defaults is a liability. A well-managed Google Workspace environment can be highly secure and effective.

If you're weighing up your options, planning a migration, or simply unsure whether your current setup is fit for purpose, get advice before committing.
