Gemini vs Microsoft 365 Copilot: The Honest Guide for UK SMBs in 2026

Your IT provider sends over a quote for Microsoft 365 Business Standard plus the Copilot add-on. You open it expecting to see something roughly in line with what you’re already paying. Instead you’re looking at over £25 per user per month — before VAT — for a 10-person team that mostly writes emails, shares files, and occasionally needs someone to summarise a long thread.

That quote is the moment a lot of UK SMB owners start googling “is there a cheaper way to get AI in my business.” The answer, for most businesses that aren’t deep in Excel or Teams, is yes.

The real numbers (as of April 2026)

Here’s what each platform actually costs on an annual plan, per user, per month, excluding VAT:

Microsoft route:

• Microsoft 365 Business Standard: £9.40/user/mo
• Microsoft 365 Copilot add-on: £16.10/user/mo
• Total: £25.50/user/mo

Google route:

• Google Workspace Business Standard with Gemini included: £11.80/user/mo
• Gemini add-on: £0 — it’s bundled
• Total: £11.80/user/mo

That’s a difference of £13.70 per user per month, or £164.40 per user per year. For a 10-person business, that’s roughly £1,644 per year. For a 20-person business, it’s over £3,200.

The pricing gap is significant because Copilot is still a bolt-on for Microsoft — it sits on top of your existing licence rather than being woven into it. Google took a different architectural decision: Gemini is part of Workspace from Business Standard upward, not a separate SKU you have to negotiate.

It’s also worth noting that Microsoft has signalled further price restructuring from July 2026 onward, with Copilot expected to be bundled into higher-tier Business Premium plans at a significantly higher base price. If you’re renewing a Microsoft contract in the next six months, it’s worth reading the small print carefully.

What Gemini can actually do in your day-to-day

Gemini isn’t a separate AI product you log in to. It’s a panel on the right side of Gmail, Docs, Sheets, Drive, and Meet. Here’s what that looks like in practice for an SMB:

Gmail: You type a rough set of bullet points — what the client asked, what you agreed, what the next step is — and Gemini drafts a properly worded reply. For businesses that spend two hours a day clearing email, this is the one that saves the most time fastest.

Google Docs: “Help me write” lets you generate a first draft from a prompt. More useful is the summarise function: paste in a long supplier document or terms-and-conditions PDF and get a plain-English summary in 10 seconds.

Google Sheets: Describe what formula you need in plain English (“add up column B only where column D says ‘invoiced’”) and Gemini writes it for you. This is the one that consistently surprises non-technical staff.

Google Meet: Gemini can take meeting notes automatically, identify action items, and send a summary to every attendee. For a small team running regular client calls, this alone is worth the price of admission.

Google Drive: Ask Gemini to find a document based on its content, not its file name. Genuinely useful when you know something exists but can’t remember what you called it.

None of these require a separate login, a separate app, or a separate budget line. They’re just there.

What Copilot does (and where Microsoft wins)

This article isn’t a Google advertisement. Microsoft’s Copilot is genuinely capable, and there are SMB use cases where it’s the right call.

The strongest Copilot use cases are Excel and Teams. If your business runs on complex spreadsheets — detailed financial modelling, production schedules with lots of interdependencies, multi-sheet data analysis — Copilot in Excel is excellent. It can explain what a formula does, suggest improvements, and generate new analysis from a plain-English question. For finance-heavy businesses or manufacturing firms with complex Bills of Materials in Excel, this matters.

Copilot in Teams is also strong. If your team lives in Teams for meetings, channels, and file sharing, Copilot’s meeting summaries, channel catch-ups (“what did I miss in the last 48 hours”), and message drafting are well-integrated.

Outlook’s Copilot integration is roughly equivalent to Gemini in Gmail — email drafting, summarisation, scheduling suggestions. Neither side has a clear edge here.

The honest summary: if your business is finance-heavy, runs complex Excel models, and your team lives in Teams, Copilot is a defensible spend. If your business is more typical of the UK SMB landscape — email, documents, video calls, shared file storage — Workspace with Gemini does the same job for less than half the price.

The migration question

The most common objection we hear from businesses on Microsoft 365 is: “We’re already set up on it. Moving is too much hassle.”

It’s a fair concern, but it’s usually overstated. For a business of 5–30 people that isn’t running custom SharePoint workflows or complex Exchange configurations, a migration from Microsoft 365 to Google Workspace is roughly a week of planned effort:

1. Domain verification and user provisioning in Google Admin: half a day.
2. Email migration (historical emails from Outlook/Exchange to Gmail): one to two days, running overnight with Google’s migration tools.
3. File migration (OneDrive/SharePoint to Drive): depends on volume, but typically automated and runnable in the background over one to two days.
4. Staff onboarding: a couple of hours of training. Gmail and Docs are not difficult to learn.

The businesses that find migration genuinely painful are the ones with deep SharePoint customisation, Teams bots, or proprietary Power Automate workflows. For everyone else, the “too much hassle” concern is mostly inertia, not a real technical blocker.

When Gemini wins — and when it doesn’t

Gemini is the right choice when:

• You have 5–30 staff and no deep technical dependency on Microsoft tools
• Your team works primarily in email, documents, and video calls
• You want AI bundled in and working from day one, not a project to configure
• You’re cost-conscious and can see exactly where the saving goes (back into the business)
• You’re starting fresh — new business, new hire, or switching for the first time

Copilot is the right choice when:

• Your business runs on Excel in a meaningful way (finance, detailed planning, data analysis)
• Your team communication infrastructure is built around Teams channels and shared channels with clients
• You’re in a regulated industry with existing Microsoft data-compliance configurations
• You’ve got a Power Platform setup (Power Automate, Power BI) you’re not willing to unpick

The honest version: most UK SMBs we talk to are in the Gemini column, not the Copilot column. They’re not finance-heavy. They don’t have a complex SharePoint build. They just want email, documents, file storage, video calls, and an AI assistant that makes all of those a bit faster. Workspace does that, and it does it for less money.

What we’ve seen in practice

We’ve helped a handful of UK SMBs evaluate and switch to Workspace with Gemini in the past year — a fabrication company, a trades firm, and a professional-services business. In each case, the conversation started with the same question: “Is the Copilot premium actually worth it for a team our size?”

In every case the answer came back the same way. The AI-in-email and AI-in-documents use cases — the ones that actually save hours in a working week — are functionally equivalent between the two platforms. The Microsoft edge cases (Excel power user, Teams-centric workflow) simply didn’t apply to these businesses. So they moved, saved the money, and the migration was done in under a week.

We’re not saying Microsoft is a bad product. We use both platforms ourselves and recommend the right one for each business. But for a typical UK SMB without a deep Microsoft dependency, the cost argument is hard to dismiss.

The £1,644-per-user-per-year question

At 10 users, the annual saving between Workspace Business Standard with Gemini and Microsoft 365 Business Standard with Copilot is over £1,600. At 20 users it’s over £3,200. At 30 users it’s approaching £5,000 per year.

That’s money that could pay for a proper AI automation project — the kind that builds something custom in your business, not just a general-purpose writing assistant. It could fund a website refresh. It could go back into the business as margin.

The question worth asking isn’t “is Gemini as good as Copilot.” For most UK SMBs, the capabilities are close enough that the answer doesn’t change the decision. The question is: what would you do with £1,600 to £5,000 a year that you’d currently be spending on an AI add-on you might not need?

Frequently asked questions

Is Gemini included in Google Workspace Business Standard, or do I have to pay extra?

As of April 2026, Gemini AI is included in Google Workspace Business Standard at no extra cost. The side panel assistant in Gmail, Docs, Sheets, Slides, Drive, and Meet is part of the £11.80/user/mo subscription. Google does offer an optional AI Expanded Access add-on for higher-volume or more advanced features (like extended image and video generation), but the core AI assistant functionality is bundled in.

What does Microsoft 365 Copilot actually cost per user in the UK?

At time of writing (April 2026), Microsoft 365 Business Standard costs £9.40/user/mo on an annual plan, and the Copilot add-on is £16.10/user/mo — giving a combined total of £25.50/user/mo. Microsoft has signalled further pricing changes from July 2026 as it moves toward bundling Copilot into higher-tier plans, so it’s worth checking current Microsoft pricing if you’re evaluating a new contract.

How long does migrating from Microsoft 365 to Google Workspace actually take?

For a typical SMB of 5–30 people without complex SharePoint or Power Platform setups, a properly planned migration takes five to seven working days. Email migration, file migration, and user provisioning can largely run overnight using Google’s built-in migration tools. Staff onboarding (Gmail, Drive, Docs) usually takes a couple of hours of guided walkthrough — not days of retraining.

Can I keep my existing domain and email address if I switch to Google Workspace?

Yes. Your existing domain (e.g. yourcompany.co.uk) carries across to Google Workspace. You set up the domain in Google Admin, update your MX records with your domain registrar, and your existing email addresses work as normal — now delivered to Gmail instead of Outlook. Your customers and suppliers see no change.
