When it comes to the Microsoft 365 vs Google Workspace UK debate in 2026, there is no shortage of opinion – but UK small and medium businesses need facts, not marketing spin. Both platforms have matured significantly, both now include AI-powered features, and both are priced competitively for the UK market. The question is not which platform is better in absolute terms, but which one fits your business, your team, and the way you actually work.
This guide breaks down the two leading cloud productivity suites head to head across pricing, features, security, collaboration, storage, and AI tooling. Whether you are a five-person start-up or a 200-seat business thinking about your next IT contract, this comparison will help you make a confident, informed decision. If you are already committed to one platform and wondering whether migration makes sense, our guide on Microsoft 365, Azure, Google Workspace, and cloud migration covers that ground in detail.

Microsoft 365: Overview
Microsoft 365 is the dominant productivity suite for UK businesses, and that position has not wavered heading into 2026. It bundles Outlook, Word, Excel, PowerPoint, OneNote, Teams, SharePoint, and OneDrive into a single subscription. For businesses that regularly produce complex documents, spreadsheets, or presentations, the desktop versions of these applications remain significantly more capable than browser-based alternatives. Plans start from around £4.50 per user per month for the Essentials tier (browser and mobile apps only), rising to around £10.30 for Business Standard (which includes full desktop installations) and around £17.60 for Business Premium, which adds advanced security tools. Most UK SMBs land on Business Basic or Business Standard. If you want to understand exactly what you are paying for, our Microsoft 365 for small business UK review goes into the value question in depth.
The strength of Microsoft 365 lies in depth. SharePoint provides powerful intranet and document management capabilities. Teams has become a central hub for communication, meetings, and internal workflow. Microsoft Defender and Microsoft Purview give IT managers granular control over data loss prevention, endpoint security, email filtering, and compliance archiving. For businesses in regulated sectors such as finance, legal, or healthcare, this compliance toolkit is genuinely difficult to replicate with a lighter platform. Microsoft also offers strong options for hybrid environments, meaning businesses still running on-premises servers can link their local infrastructure with the cloud service without wholesale migration.
The main criticisms of Microsoft 365 are fair ones. The admin centre is complex, licensing can be confusing, and layering on additional services such as Microsoft Copilot (the AI assistant) costs extra, currently priced at around £25 per user per month as an add-on. For smaller businesses without dedicated IT support, the platform can feel over-engineered. There are also cases where certain Teams or SharePoint configurations require careful planning to avoid a mess of permissions and duplicate files. That said, for any business that has relied on Office for years and does not want to retrain staff, Microsoft 365 is the natural home.
Google Workspace: Overview
Google Workspace (formerly G Suite) offers Gmail, Google Drive, Docs, Sheets, Slides, Meet, Chat, Calendar, and Forms. It is a browser-first platform built around simplicity, real-time collaboration, and speed of deployment. There are no desktop applications to install and no complex local configurations to manage. Business Starter plans start from around £4.60 per user per month and include 30GB of pooled storage and Google Meet. Business Standard, at around £9.20 per user per month, adds larger pooled storage, Meet recording, and noise cancellation. Business Plus and Enterprise plans include advanced audit and compliance features and access to more pooled storage. Google has also been including its Gemini AI assistant on higher plans, which gives Google Workspace a competitive edge on AI features at a comparable price point to Microsoft 365 mid-tier plans. For a broader picture of what the platform includes, see our Google Workspace: What Is Google Workspace guide.
Google Workspace genuinely excels at real-time collaboration. Multiple users working on the same Google Doc, Sheet, or Slide simultaneously is a smoother experience than co-authoring in Microsoft 365, particularly on slower connections. The admin console is clean and approachable, making it practical for a business owner without deep IT expertise to manage user accounts, email routing, and security settings. Gmail is also widely trusted as a business email platform, and Google Meet has improved substantially, offering reliable video conferencing without requiring a downloaded client. For businesses hiring remote workers across the UK or internationally, Google Workspace is easy to provision and requires no local infrastructure.
The weaknesses of Google Workspace are real, however. The lack of desktop applications is a genuine disadvantage for users who work offline regularly, such as those travelling by rail or working in locations with poor connectivity. Google Docs and Sheets are capable, but they do not match the advanced functionality of Excel for complex financial modelling or Word for long-form document production with tracked changes and detailed formatting. File format compatibility can also cause friction when sharing documents with clients or partners who use Microsoft Office, as the conversion between formats is not always seamless. Compliance tooling, while improving, does not yet match the breadth of Microsoft Purview for businesses with strict regulatory obligations.
Security and Compliance
Both platforms take security seriously and both are suitable for UK businesses under UK GDPR. Microsoft 365 Business Premium includes Microsoft Defender for Business, advanced threat protection, Intune for device management, and Azure Active Directory Premium features. This makes it one of the most comprehensive security stacks available at an SMB price point. Google Workspace includes strong built-in protections covering spam filtering, phishing detection, two-factor authentication, and mobile device management. Both platforms offer UK data residency options, which is relevant for businesses that need to confirm where data is stored. For businesses looking to strengthen their authentication posture alongside either platform, pairing your subscription with a hardware key such as the Yubico Security Key is a straightforward and effective upgrade that works with both services.
If compliance is a primary driver for your decision, Microsoft 365 Business Premium is the more complete solution out of the box. For most SMBs with standard security requirements, both platforms provide a solid baseline when configured correctly.
AI Features in 2026
AI has become a genuine differentiator between the two platforms. Microsoft Copilot is deeply integrated into Word, Excel, Outlook, Teams, and PowerPoint, offering draft generation, meeting summaries, data analysis prompts, and email triage. However, Microsoft Copilot is priced at around £25 per user per month as an add-on on top of your existing licence, which adds up quickly for a 20-seat team. Google has taken a different approach, bundling Gemini for Workspace into Business Standard and above plans without a separate AI surcharge. Gemini can draft emails in Gmail, summarise documents in Drive, generate content in Docs, and provide meeting summaries in Meet. For cost-conscious UK SMBs, the included AI in Google Workspace plans at mid-tier pricing represents better value in 2026 if AI tooling is important to your decision.
Which Should You Choose?
Choose Microsoft 365 if: your team relies on advanced Excel or Word functionality, you run a hybrid environment with on-premises servers, you need enterprise-grade compliance and security tools (particularly at Business Premium level), your staff are already trained on Office applications and retraining would be disruptive, or you operate in a regulated sector such as legal or financial services. Microsoft 365 is also the safer choice if most of your clients or supply chain contacts share Office-format documents, as native compatibility avoids conversion headaches.
Choose Google Workspace if: your team works primarily in a browser or on Chromebooks, you want a simpler admin experience without deep IT expertise, you are starting fresh and want to avoid the complexity of Microsoft licensing, real-time collaborative editing is a daily priority, or you want AI tools included without paying an additional per-user premium. Google Workspace also tends to suit businesses that are fully remote or operate across multiple time zones, where the lightweight, browser-first approach reduces friction considerably.
If you are genuinely unsure: Microsoft 365 Business Standard is the safer default for most UK SMBs because of its broad compatibility, desktop application access, and the familiarity of the Office suite. If after six months you find the team only ever opens a browser, it may be worth reassessing. Many UK businesses also use a hybrid approach, retaining Microsoft 365 licences for core document-heavy roles and using Google Workspace features for lighter collaboration tasks, though this adds administrative overhead and is rarely necessary when one platform is chosen well from the outset.

Frequently Asked Questions
Is Microsoft 365 or Google Workspace cheaper for UK businesses in 2026?
At the entry level, both platforms are priced similarly, starting from around £4.50 to £4.60 per user per month. Google Workspace Business Standard at around £9.20 per user per month is slightly cheaper than Microsoft 365 Business Standard at around £10.30 per user per month, and Google includes its Gemini AI features at no additional cost on some plans. Microsoft charges separately for Copilot at around £25 per user per month, which makes Google Workspace meaningfully cheaper if AI features are a priority. For larger teams, the difference in per-seat pricing can become significant over a 12-month contract.
Can I use Microsoft Office files with Google Workspace?
Yes, Google Workspace can open, edit, and save files in Microsoft Office formats including .docx, .xlsx, and .pptx. However, the conversion is not always perfect, particularly for complex documents with advanced formatting, macros, or tracked changes. For businesses that exchange documents heavily with clients or partners using Microsoft Office, this compatibility gap is worth factoring into your decision. If precision formatting and macro functionality are critical, Microsoft 365 is the more reliable choice.
Which platform is better for remote and hybrid teams in the UK?
Both platforms support remote working well, but Google Workspace has a slight edge for fully remote teams thanks to its browser-first approach, which requires no local software installation and works consistently across devices and operating systems. Microsoft 365 with Teams is also a strong choice for hybrid teams, particularly when combined with desktop applications for users in the office. If your team is entirely browser-based and geographically distributed, Google Workspace will typically be easier to deploy and manage without dedicated IT support.
Does Microsoft 365 or Google Workspace offer better security for small businesses?
Both platforms offer strong baseline security, including two-factor authentication, spam and phishing protection, mobile device management, and UK data residency options. Microsoft 365 Business Premium provides the most comprehensive security toolkit available at SMB pricing, including Microsoft Defender for Business, endpoint management via Intune, and advanced compliance features via Microsoft Purview. For most small businesses with standard security requirements, either platform is sufficient when configured correctly. For businesses in regulated industries or handling sensitive data, Microsoft 365 Business Premium is the stronger and more complete option.
Can I switch from Microsoft 365 to Google Workspace, or vice versa?
Yes, migration between the two platforms is achievable, but it does require planning. Email, calendar, and contacts can be migrated using built-in tools or third-party migration services. Document migration is more involved, particularly if you have a large library of SharePoint content or complex Office files. Staff retraining time should also be factored in, as the interfaces and workflows differ substantially. For businesses considering this move, our cloud migration guide covers the practical steps in detail. Engaging a UK Microsoft or Google partner to assist with migration is strongly recommended for any business with more than ten users.
