Microsoft 365 Business Basic vs Standard vs Premium — Which Plan Do UK SMBs Actually Need?

Microsoft 365 Business Basic, Standard, and Premium are three tiers that look similar on a pricing page but differ significantly in what they actually deliver. Choosing the wrong one means either paying for features you'll never use or — more often — missing critical security and productivity tools that your business genuinely needs. This guide cuts through the marketing language and explains what each plan includes, what it costs, and which one makes sense for a typical UK small business.

The Three Plans at a Glance

As of 2026, the Microsoft 365 Business plans are priced per user per month (billed annually through Microsoft or a UK reseller). The three tiers are:

  • Business Basic — approximately £5.10 per user per month
  • Business Standard — approximately £10.30 per user per month
  • Business Premium — approximately £18.60 per user per month

All three include Exchange email with a custom domain, Microsoft Teams, SharePoint, and 1TB of OneDrive storage per user. The differences begin when you look at the desktop apps, advanced features, and security capabilities.

Microsoft 365 Business Basic

Business Basic is the entry-level tier. It gives you web and mobile versions of the Office applications — Word, Excel, PowerPoint, Outlook — but not the full desktop apps. That means your team works in a browser or on a mobile device, not in the installed applications most people are accustomed to.

Who Business Basic suits

Basic works well for employees who spend most of their time in Teams and email, and who don't need to work with complex spreadsheets, formatted documents, or offline access to their files. It's appropriate for roles like receptionists, drivers, or field workers who primarily need communication tools rather than document creation. It's also a sensible choice if you have a mix of staff with different needs — some on Basic, others on Standard or Premium.

Where Business Basic falls short

If your team regularly uses Excel for anything beyond basic data entry, or if they create formatted Word documents or PowerPoint presentations, the browser-based versions will frustrate them. Web apps lack features, behave differently from the desktop versions, and require an internet connection at all times. For most office-based roles, Basic is a false economy.

Microsoft 365 Business Standard

Standard adds the full desktop Office applications — the installed versions of Word, Excel, PowerPoint, Outlook, Access, and Publisher — along with a few additional features including Microsoft Bookings and webinar hosting through Teams. This is the plan that most UK small businesses should default to for their core office staff.

Who Business Standard suits

Standard is appropriate for any employee who works with Office documents regularly, needs offline access to their files, or uses advanced features in Excel or Word. It covers the majority of roles in a typical small business: administrators, account managers, finance staff, project managers. The price difference over Basic is modest, and the productivity benefit of proper desktop applications is significant.

Features worth highlighting in Standard

Beyond the desktop apps, Standard includes the full Microsoft Teams experience with recording and transcription, SharePoint team sites, and the ability to host customer-facing webinars. For many small businesses, these alone justify the upgrade from Basic. There are also features in Microsoft 365 that most teams never activate — see our post on five Microsoft 365 features your team isn't using for a practical guide to getting more from your subscription.

Microsoft 365 Business Premium

Premium includes everything in Standard and adds a substantial layer of security and device management features. The key additions are:

  • Microsoft Intune — cloud-based device management, allowing you to enforce security policies, push software, and remotely wipe devices
  • Microsoft Defender for Business — enterprise-grade endpoint detection and response (EDR) for your laptops and desktops
  • Azure AD Premium P1 — advanced Conditional Access policies for controlling when and how users can sign in
  • Microsoft Purview Information Protection — data classification, sensitivity labels, and data loss prevention
  • Autopilot — zero-touch laptop deployment for new starters

Who Business Premium suits

Premium is the right choice for businesses that handle sensitive customer data, need to meet regulatory requirements, or want to achieve Cyber Essentials Plus certification. It's also the appropriate tier if your team works remotely or uses personal devices to access business systems, since Intune allows you to enforce security policies on those devices without fully managing them.

For businesses serious about cybersecurity, Premium represents exceptional value. Buying equivalent security tools separately — endpoint detection, device management, identity protection — would cost significantly more than the premium over Standard.

Which Plan Does a UK Small Business Actually Need?

The honest answer for most small businesses: Business Standard for the majority of staff, with Business Premium for anyone handling sensitive data or working remotely. It's perfectly acceptable to have a mix of licences — Microsoft allows it, and your IT provider can manage the mix through the admin centre.

Lasetech typically recommends Premium for all staff when a business is working towards Cyber Essentials, has had a security incident, or employs remote workers without company-issued devices. The additional cost per user is modest compared to the protection it provides, and it simplifies management considerably.

Frequently Asked Questions

Can I mix Microsoft 365 Business Basic, Standard, and Premium licences?

Yes. Microsoft allows you to assign different licence tiers to different users within the same organisation. A common setup is Standard for most staff and Premium for directors or employees who handle sensitive data. Your IT provider or Microsoft partner can help you configure this through the Microsoft 365 Admin Centre.

Does Microsoft 365 Business Premium include antivirus?

Yes — Premium includes Microsoft Defender for Business, which provides endpoint protection, threat detection, and automated remediation for your Windows devices. It's a significant step up from the basic Windows Defender included with consumer Windows licences and is comparable to third-party enterprise antivirus products.

Is Microsoft 365 Business Basic suitable for a small business?

It depends on your team's needs. Basic is appropriate for employees who primarily use email and Teams and don't need the full desktop Office applications. For roles that involve regular document creation, data analysis, or working offline, Standard is the minimum appropriate tier. Most small businesses find that Basic-only setups frustrate staff who expect the familiar desktop Office experience.

What happens if I exceed the 300-user limit on Microsoft 365 Business plans?

The Business tier (Basic, Standard, and Premium) is limited to 300 users per organisation. Above that threshold, you would move to Microsoft 365 Enterprise plans (E1, E3, or E5), which have no user cap. For the vast majority of UK small businesses, the 300-user ceiling is more than sufficient.
