If you use Microsoft 365, you have probably noticed the Copilot icon in Outlook, Word or Teams and wondered whether it is worth paying for. Microsoft's marketing makes it sound transformative. The reality for a small business is more nuanced. Copilot can save time, but only for the right people, doing the right tasks, on a Microsoft 365 setup that is in good order.
This guide gives you an honest picture before you buy any licences.
What Microsoft 365 Copilot actually is
Copilot is Microsoft's AI assistant, built into the Microsoft 365 apps your team already uses. The important difference from a general chatbot is that the paid version can draw on your organisation's own data: your emails, documents, calendar, Teams chats and meeting recordings, all within the permissions each user already has.
There are broadly two levels:
- Copilot Chat: a free AI chat tool for anyone signed in with a work Microsoft account. It works on information from the web and anything you paste or upload into it, with business-grade data protection.
- Microsoft 365 Copilot: the paid add-on licence. This is the version that works inside Word, Excel, Outlook, PowerPoint and Teams and can search across your company's files and emails.
Many small businesses don't realise the free option exists, and it is a sensible place to start experimenting.
What it can do day to day
Used well, the paid version can help with tasks like these:
- Outlook: summarising long email threads, drafting replies and catching up after time off.
- Teams: producing meeting summaries and action points, or answering "what did I miss?" if you join late. This depends on meetings being transcribed.
- Word: drafting a first version of a document, policy or proposal from your notes or existing files, and summarising long reports.
- PowerPoint: turning a Word document into a draft presentation.
- Excel: helping analyse data, suggest formulas and spot trends, though it works best with tidy, well-structured tables.
- Across Microsoft 365: asking questions like "find the latest version of our health and safety policy" or "what did we agree with this supplier last month?"
What it won't do is replace judgement. Copilot can be confidently wrong, it may miss context, and everything it produces needs checking by a person who understands the subject.
What it costs
Microsoft 365 Copilot is sold as a per-user, per-month add-on on top of an eligible Microsoft 365 plan, such as Business Basic, Business Standard or Business Premium. You don't have to buy it for everyone; you can license just the people who will benefit most.
We won't quote a figure here because Microsoft's pricing, bundles and commitment terms (monthly versus annual) change fairly often, and the right option depends on your existing licences. What we can say is that it is a meaningful extra cost per person, so it is worth being selective rather than rolling it out across the whole team on day one.
The part people overlook: data permissions
This is the most important point in this article. Copilot respects your existing permissions, which sounds reassuring, but it also means it will surface anything a user can technically access, even if they never knew it was there.
In many small organisations, permissions have built up over years. A folder of salary information shared with "everyone" by mistake, an old SharePoint site left open, a former manager's OneDrive shared widely. Before Copilot, nobody stumbled across these. With Copilot, a simple question could bring them straight to the surface.
For schools, charities and care providers handling sensitive personal data, this matters even more under UK GDPR. Before switching Copilot on, it is wise to:
- Review who has access to SharePoint sites, Teams and shared folders.
- Remove "anyone with the link" and organisation-wide sharing where it isn't needed.
- Tidy up old files and sites belonging to former staff.
- Consider sensitivity labels for confidential information, if your plan supports them.
- Agree a simple AI usage policy so staff know what is and isn't appropriate.
So, is it worth it?
It depends on how your team works. Copilot tends to pay off for people who:
- Spend a large part of their day in email, meetings and documents.
- Regularly write reports, proposals, bids or policies.
- Need to pull information together from lots of places.
It is usually harder to justify for staff who mainly use specialist line-of-business software, work on the shop floor or in the field, or only touch Microsoft 365 occasionally.
A sensible way to approach it
- Start with the free Copilot Chat and see how your team takes to AI.
- Tidy up permissions and file storage first. This is good practice anyway.
- Pilot paid licences with a handful of enthusiastic users for a couple of months.
- Give them some basic training on writing good prompts and checking output.
- Ask them honestly whether it saved meaningful time, then decide whether to expand.
