Copilot is the AI question most UK small businesses face first, because it arrives in the renewal quote rather than as a decision anybody went looking for. It is also the one where the honest answer is genuinely it depends, and the thing it depends on is not what most people expect.
Where it genuinely earns its licence
Four uses come up consistently in businesses where Copilot has stuck.
Meeting summaries in Teams
The strongest single use, and the one that converts sceptics. A recorded meeting produces a summary, a list of decisions and a list of who agreed to do what, within a minute of the call ending. It catches up somebody who missed it in ninety seconds, and it removes the worst part of most people's week.
Worth knowing the consent position before you switch it on across the business — covered here.
Outlook thread summaries and draft replies
A forty-message thread you have been copied into becomes four bullet points and a note of what is being asked of you. For anyone who returns from a week off, this is the feature that pays for the month.
Excel analysis in plain English
Asking a spreadsheet a question rather than building the formula. Genuinely good for exploratory work — which customers ordered less this quarter than last — and genuinely unreliable for anything you then act on financially without checking. Treat it as a fast way to form a hypothesis.
Drafting from your own material
A proposal drafted from a previous one plus the notes from the site visit. Not finished work, but the difference between a blank page and something to argue with.
Where it disappoints
Three patterns, and all three are predictable in advance.
Businesses that live in a line-of-business system. If your day happens in a job management platform, a practice management system or a bespoke database, Copilot cannot see any of it. It reads Microsoft 365 content. A licence for somebody whose real work lives elsewhere is a licence for the twenty per cent of their day spent in email.
Businesses with heavy file duplication. Copilot answers from what it finds, with complete confidence. Find six versions of the price list and it will quote one of them. This is the most common cause of a business concluding that Copilot is unreliable, and the fault is in the file estate rather than the tool.
Businesses that bought licences for everybody. Usage per licence falls, nobody has a specific task and the renewal conversation twelve months later has no evidence in it.
Copilot's quality is a direct function of how tidy your SharePoint is. Nobody wants that to be the answer, and it is the answer.
The permissions problem, stated plainly
Copilot respects existing permissions exactly. It shows a person only what that person could already open.
The difficulty is that could already open and could realistically ever have found have been very different things for years. A folder shared organisation-wide in 2021 for one afternoon. A departed employee's OneDrive still shared with the team. A HR spreadsheet in a location nobody thought about.
None of that was reachable when finding it required knowing it existed. It becomes reachable the moment somebody can ask a question in plain English.
Run a sharing review before rollout — organisation-wide shares, anonymous links, departed staff and anything containing salary, health or disciplinary material. Two days of work, and doing it afterwards is a much less comfortable exercise. Our security solutions team does this as a standard pre-Copilot step.
What changed in 2026
Copilot moved from a chat assistant to something closer to an agent. Agent mode became the default experience across the Microsoft 365 applications, agents in SharePoint reached general availability, and Copilot gained the ability to carry out multi-step tasks and trigger workflows through Power Automate.
That matters for the buying decision because it shifts the value from helps a person write faster towards completes a process. It also raises the stakes on the two prerequisites above, since an agent acting on the wrong document does more than quote it.
How to decide
Three questions, honestly answered.
- Where does the work happen? If most of the day is in Outlook, Teams, Word and Excel, Copilot is well placed. If it is elsewhere, look at automation instead.
- Could a new starter find your current price list in two minutes? If not, fix that before buying licences.
- Do you know what is over-shared? If not, that is the first job regardless of what you decide about AI.
If all three answers are good, start with three or four licences for the heaviest writers and triagers, run a quarter and expand on evidence.
The alternative worth considering
For businesses where the honest answer to question one is elsewhere, a separate assistant on a business plan for two or three people, plus a couple of properly built automated workflows, frequently delivers more for less. It is less tidy and it is often the better buy.
If you want a straight opinion on which of those fits your business, our IT consultancy team will look at where your work actually happens and tell you. Get in touch — we would rather tell you not to buy something than sell you a licence that goes unused.
