Is Microsoft 365 Copilot worth it for a small business?

Microsoft keeps putting Copilot buttons in front of your team, and the paid version costs more per person than many firms pay for Microsoft 365 itself. So is Copilot worth it for a small business? Sometimes, yes. But not for everyone, and not before a bit of tidying up. Here's what it actually does, what you already get free, and how to find out cheaply whether it's worth paying for.

The short answer

• Start with the free Copilot Chat. It comes with eligible Microsoft 365 business plans and covers a lot of everyday drafting and summarising.
• The paid licence (Microsoft 365 Copilot Business) adds Copilot that can search your own email, files, chats and meetings. Microsoft's UK list price is £16.10 +VAT per user a month, paid yearly, as of October 2026.
• It pays off for people who write, summarise or sit in meetings a lot. It does far less for someone who spends the day on the phone, in a van or in a specialist app.
• Fix your sharing first. Copilot shows people anything they already have access to, including things they were never meant to see.
• Try it with two or three people for a couple of months before buying for everyone.
• Copilot isn't your only choice. Having Microsoft 365 doesn't lock you into Microsoft's AI, and other AI tools are worth comparing.

What does Copilot actually do?

With the paid licence, Copilot sits inside the Microsoft 365 apps you already use:

• Outlook: summarises long email threads, drafts replies and helps you catch up after time off.
• Word: drafts documents from your notes or existing files, rewrites, and summarises long documents.
• Excel: helps analyse a table, suggests formulas and charts, and explains what the numbers show.
• PowerPoint: turns a document or an outline into a first-draft presentation.
• Teams: recaps meetings, lists actions, and lets you ask "what did I miss?" if you joined late.
• Copilot Chat with work data: answers questions like "what did we agree with this supplier last month?" by searching across email, chats, meetings and files you're allowed to see.

It's a capable assistant, not a replacement for anyone. Microsoft's own pages and the NCSC both make the point that AI can get things wrong and present mistakes as facts. Everything it writes is a first draft that a person checks.

Copilot Chat free vs paid: what's the difference?

This is where most of the confusion sits. Microsoft uses the word "Copilot" for several things.

The key difference is grounding: what Copilot can see when it answers. Microsoft describes the free Copilot Chat as "primarily web grounded". It knows the internet and whatever you give it. The paid licence can reason across your whole Microsoft 365 account, within each person's permissions.

If your team mainly wants help writing emails, tidying wording or summarising a document they can upload, the free version may be all you need.

How much does Copilot cost in the UK?

These are Microsoft's UK list prices as shown on its website on 30 October 2026, per user per month, paid yearly:

A few things to know:

• The Business add-on is for organisations of up to 300 users, and it needs an eligible Microsoft 365 business plan underneath it.
• Microsoft says some advanced AI features are billed on usage, on top of the licence fee. You can control that spend, but it's worth knowing before you switch everything on.
• It's an annual commitment that renews automatically, so a licence bought for someone who never uses it is money gone for the year.

Through us, the Copilot Business add-on is from £20.93 +VAT per user a month, and our Microsoft 365 licences start from £7.02 +VAT per user a month. At our price, adding Copilot for everyone in a 10-person team would be about £2,500 +VAT a year. Adding it for three people is about £750 +VAT a year.

Is Copilot worth it for your small business, or should you wait?

It's more likely to pay off if:

• people spend a big part of their day in email, documents and Teams meetings;
• you write a lot of similar things: proposals, quotes, reports, letters, policies;
• managers lose time catching up on long threads or meetings they couldn't attend;
• your files already live in SharePoint, OneDrive and Teams, reasonably organised.

It's probably worth waiting if:

• most of your team works on the phones, on site, on the shop floor or in a specialist system;
• your files are still on a local server or someone's desktop (Copilot can't use what isn't in Microsoft 365);
• sharing in your Microsoft 365 is a free-for-all and nobody's sure who can see what;
• you haven't tried the free Copilot Chat properly yet.

The UK government ran a large Copilot trial in late 2024: 20,000 civil servants across 12 organisations over three months. People's own estimate was an average of 26 minutes saved a day, mostly on drafting documents. The report is honest about the limits, though. The figures are self-reported, 17% of people said they saw no clear time saving, and human checking was needed throughout. That's a useful guide to what to expect: real gains for some jobs, little for others.

What needs to be in place first?

Copilot follows your existing Microsoft 365 permissions. It doesn't break them, but it does make them visible. If a salary spreadsheet sits in a folder shared with "everyone", Copilot can find it for anyone who asks the right question. Microsoft's own guidance for a Copilot rollout starts with sorting out oversharing for exactly this reason.

Before you buy, check:

1. Your licences. Everyone who'll use Copilot needs an eligible Microsoft 365 business plan.
2. Where your files live. Move what matters into SharePoint, OneDrive and Teams, and archive what's out of date so Copilot doesn't quote last year's prices.
3. Who can see what. Review "anyone with the link" and company-wide sharing, and lock down HR, finance and director-only folders.
4. Security basics. Multi-factor sign-in (a code on your phone as well as the password) for everyone, and leavers' accounts closed.
5. A short AI policy. What staff may use AI for, what must be checked by a person, and what personal data shouldn't go into it. UK GDPR still applies when AI handles personal data.

How to try Copilot without wasting money

1. Pick two or three people whose days are mostly email, documents and meetings.
2. Agree three or four real jobs to try it on, like weekly reports, quotes or meeting notes.
3. Give them a short how-to session and some example prompts. People who aren't shown how to use it tend to give up.
4. After six to eight weeks, ask each person honestly: what did it save, what did it get wrong, would you miss it?
5. Then decide: more licences, stay as you are, or rely on the free Copilot Chat.

The tidy-up pays off even if you never buy Copilot.

Don't feel locked into Copilot

Copilot's big advantage is that it sits inside the Microsoft 365 apps and can search your own email and files. That doesn't make it the best AI for every job. ChatGPT (OpenAI), Claude (Anthropic) and Google's Gemini all sell business plans, and for some work, like long documents, research, analysis or writing code, people often find one of them stronger.

Having Microsoft 365 doesn't mean you have to use Microsoft's AI. If you're comparing options:

• Try the actual jobs you want help with in two or three tools, not the demos.
• Use a business plan, not a personal account, and check what the provider does with your data and whether it's kept out of training.
• Check how it fits with your files. Some tools connect to SharePoint and OneDrive, others work only on what you upload.
• Keep your AI policy the same whichever tool you pick: what staff may use it for, what a person must check, and what personal data stays out.

Some businesses end up with the free Copilot Chat for everyday drafting and a different tool for the heavier work. That's a perfectly sensible answer.
