Microsoft 365 Copilot for a small team: is it worth paying for?

If your business runs on Microsoft 365, you'll have noticed Copilot appearing in more and more places. There's a Copilot button in Word, a Copilot icon in Outlook, and perhaps a note from Microsoft or your IT provider suggesting you upgrade.

It's reasonable to wonder whether you're missing out, and equally reasonable to be wary of adding another monthly cost per person. The good news is that this isn't an all-or-nothing decision. You can find out whether Copilot earns its keep in your business with a small, well-planned trial.

This article explains what Copilot actually is, what you already have for free, what it needs to work well, and how to judge whether the paid version is worth it for your team.

A quick note on our position: we supply Microsoft licences and know these tools well, but the right choice depends on your business, and sometimes that's a different tool or no new tool at all.

Two kinds of Copilot

Microsoft uses the Copilot name for several things, which doesn't help. For a small business using Microsoft 365, there are two that matter.

Microsoft 365 Copilot Chat is an AI chat assistant that Microsoft describes as available at no additional cost for users with an eligible Microsoft 365 subscription. It works in the browser, in Edge and in the Microsoft 365 app. It can answer questions using information from the web, help draft and rewrite text, and work with files you upload to it. Because people sign in with their work account, it comes with Microsoft's enterprise data protection, which is a good reason to point staff towards it rather than a free consumer AI tool.

Microsoft 365 Copilot (sold to small businesses as Microsoft 365 Copilot Business) is the paid version. It sits inside the apps your team already uses and, importantly, can draw on your own work information: emails, meetings, chats and documents. In practice that looks like:

Outlook: summarising a long email thread and drafting a reply
Teams: recapping a meeting you missed, including decisions and actions
Word: producing a first draft from your notes or from existing documents
Excel: helping to analyse a table and suggest formulas or charts
PowerPoint: turning a document into a first-draft presentation

The paid licence also includes some ready-made "agents" (assistants for specific jobs, such as researching a topic across your files and the web) and reporting on how Copilot is being used.

The key difference is access to your own work information. Copilot Chat is a capable general assistant. The paid licence is an assistant that knows what's in your inbox, your meetings and your shared files.

What it costs, and how it's bought

At the time of writing, Microsoft's UK Copilot pricing page lists the Copilot Business add-on for organisations of up to 300 users. It needs an eligible Microsoft 365 business plan alongside it.

On an annual commitment, it's listed from £13.80 per user per month under an offer running until 31 December 2026, and normally from £16.10
Paying monthly instead is listed at £19.32 per user per month
There are also combined plans, such as Microsoft 365 Business Standard with Copilot, if you'd rather have a single licence

Prices and offers change often, so check the current figures before you decide. The more useful point is that licences are per person. You don't need to buy Copilot for everyone. Many small businesses start with a few people whose work is heavy on email, meetings and documents, and grow from there if it proves worthwhile.

What Copilot needs to work well

This is the part that's easy to overlook, and it has more influence on your results than the licence itself.

Tidy permissions. Microsoft states that Copilot only surfaces information that each user already has permission to see. That's reassuring, but it also means Copilot reflects your current sharing settings back to you. If a folder of salary information was shared with "everyone" years ago and forgotten, a colleague could now find it simply by asking a question. Nothing has been breached; the old setting has just become easier to notice.

Organised files. Copilot works best when documents live in SharePoint, OneDrive and Teams rather than on desktops, old file servers or personal Dropbox accounts. If your team has five versions of the price list, Copilot may confidently quote the wrong one.

People who know what to ask. A short session on how to give Copilot clear instructions, and what to check in its answers, makes a noticeable difference. People who get a poor first result often give up, when a slightly better request would have worked.

None of this is a reason to wait indefinitely. A few hours reviewing who can see what, particularly in shared sites and folders holding HR, finance or client information, is good housekeeping that pays off with or without Copilot.

Run a small pilot

Rather than buying licences for the whole team, run a pilot of four to eight weeks.

Choose three to five people who would benefit most. Good candidates spend much of their day in Outlook and Teams, write a lot of documents, or pull together reports from several sources.
Agree two or three tasks each, such as meeting recaps, drafting client proposals from previous ones, or summarising long email threads.
Do the permissions check first, at least for the areas those people can reach.
Give them a short introduction and a place to share tips with each other.
Buy monthly if you can, even at a slightly higher price, so you're not committed for a year before you know the answer. Check the current terms, as commitment options vary.

It also helps to have the people in the pilot try Copilot Chat for a week beforehand. That gives you a fair comparison: what does the paid version add over the free one, for these people and these tasks?

How to judge whether it's worth it

At the end of the pilot, sit down with the people involved and ask a few plain questions:

Which tasks became faster or easier, and roughly how much time did that free up each week?
Was the quality good enough, or did outputs need a lot of correction?
Did people use it every day, or drift back to old habits after the first fortnight?
Would they genuinely miss it if the licence were removed?

Then compare the time saved with the cost. You're not after precise figures. If one person saves an hour or two a week on meeting notes and email, that's usually easy to weigh against a monthly licence. If people struggled to find a regular use for it, that's a useful answer too.

The outcome might be to extend Copilot to more people, to keep it for a few roles, or to stay with Copilot Chat for now and revisit in six months. All of these are sensible results. If you're still weighing up AI more broadly, our article on where to start with AI covers the wider picture.

A sensible first step

This week, try two things:

Make sure your team knows about Copilot Chat and is using it with their work account, rather than a personal AI tool. Many businesses already have it and don't realise.
Pick one shared area, such as your main SharePoint site or the Teams channel that holds client work, and check who has access. If anything surprises you, tidy it up.

Those two steps cost nothing, and they'll tell you a lot about whether a paid Copilot pilot makes sense and how ready you are for it.
