Microsoft Copilot vs Business Premium: What to Buy First (2026 UK)

One of the most common questions we get: "Should I spend on Copilot, or just get Business Premium?"

It's the wrong question — but an understandable one because the marketing is confusing. Here's the clear version:

Business Premium and Copilot are not alternatives. Copilot requires Business Standard or Premium as a prerequisite.
You can buy Standard + Copilot, or Premium + Copilot, but never Copilot alone.
The real choice is "do I add Copilot?" — on top of whatever tier I'm already on.

So the question becomes: is Copilot worth the per-user monthly cost?

Short answer: for some specific roles, yes. For most staff, not yet.

What Copilot actually is

Microsoft 365 Copilot is an AI assistant that works inside Word, Excel, PowerPoint, Outlook and Teams. Common things it does:

Outlook: draft replies, summarise long email threads, catch up on what you missed while on holiday
Word: generate first drafts, rewrite sections, summarise documents
Excel: suggest formulas, analyse data, explain what a complex spreadsheet is doing
PowerPoint: create slides from a Word document, redesign existing slides
Teams: summarise meetings you missed, pull action items from meeting recordings

It also has a standalone "Copilot Chat" mode that can search across your own company's files — documents, emails, Teams chats — and answer questions with citations.

The cost

Copilot is priced per user per month (ex VAT) on an annual commitment. It requires a qualifying base licence:

Microsoft 365 Business Standard — qualifies
Microsoft 365 Business Premium — qualifies
Business Basic — does not qualify
Apps for business — does not qualify

So the minimum combined cost is a base tier plus Copilot. We'll confirm exact pricing when you enquire.

For a 20-user firm where only 5 users take Copilot, you pay the base licence for everyone and add Copilot for just those five — far less than licensing the whole team.

When Copilot is clearly worth it

We've seen genuine productivity wins in these roles:

Professional services (consultants, lawyers, accountants) who write a lot. Draft generation for Word, summarising long client threads in Outlook, Excel formula help. Often saves 3-5 hours a week per user.
Sales teams. Catching up on threads before a call, summarising meetings, drafting follow-ups. Easy ROI given what it costs to employ good sales staff.
Senior managers who live in meetings. Teams meeting summaries and action items are genuinely useful — a senior in 20 meetings a week saves real time.
Data analysts (light). Excel data analysis, formula explanation, pattern spotting for people who aren't full-time analysts.
Marketing / content roles. Draft assistance in Word, slide generation in PowerPoint.

For these people, the monthly cost is well under an hour of their time. Payoff is clear.

When Copilot is a waste

That same per-user monthly cost adds up to a meaningful sum per person each year. Not trivial. For these roles, it doesn't earn that back:

Field staff, trades, engineers — they live in a van or on site. They don't open Word.
Reception, admin, warehouse — volume of "knowledge work" is low. Copilot sits idle.
Staff who don't use Microsoft 365 apps heavily (field sales on a mobile, floor staff). If they mostly use Teams for messaging and Outlook briefly, Copilot won't get used enough to justify cost.
Anyone resistant to AI tools — if they won't try it, you pay for nothing all year. Harsh but true.

Giving Copilot to every user by default is expensive waste. Give it to the 20-30% who genuinely benefit. Review quarterly.

The "licence creep" trap

Microsoft's sales people will push Copilot on everyone. Resist.

A 50-user firm licensing Copilot across the board pays for fifty seats every month, all year — a substantial annual bill on top of your Microsoft 365 base. Half the users won't use it enough to care.

A thoughtful mix — say 15 users on Copilot, 35 without — costs a fraction of that. Same productivity win for the people who actually use it, with a big saving over licensing everyone.

But Business Premium — is THAT worth the jump from Standard?

Different question. The small monthly gap from Standard to Premium buys you:

Microsoft Defender for Business
Microsoft Intune (device management)
Entra ID P1 (conditional access, MFA enforcement)

Bought standalone, those security products would cost more than the Premium upgrade itself. Premium is already cheaper than Standard plus the security add-ons. See our Standard vs Premium write-up for the detail.

If your business has compliance requirements, remote staff, personal devices accessing work data, or handles client information — Business Premium earns its price easily, and before you even think about Copilot.

The sensible order of spend

Most UK SMBs we work with prioritise in this order:

Get on a Business tier that matches your security profile (Basic, Standard, or Premium)
If you handle client data, get Premium — the security stack pays for itself
Add Copilot to roles that write / analyse heavily — 20-30% of staff, not everyone
Review Copilot usage every 3-6 months — pull licences from users who never use it, give them to new hires who will

Don't buy Copilot for "future-proofing" — if it's not being used, you're just bleeding money.

Does CTN include Copilot in the bundle discount?

Yes. Our 10% bundle discount (when you take Microsoft 365 alongside CTN VoIP) applies to Copilot as well as your base licence, so bundle customers pay less per user for Copilot.

FAQs

Can I get Copilot without Business Standard or Premium?

No. Copilot requires one of those tiers (or an equivalent enterprise tier — E3/E5). It's not a standalone product.

What's the difference between Copilot and Copilot Pro?

Microsoft 365 Copilot is the business product covered here — priced per user per month, requires a business licence. Copilot Pro is for personal use with personal Microsoft accounts. Copilot Pro is not appropriate for business use — no admin controls, no data separation, no compliance.

Is Copilot's data secure?

Yes, contractually. Microsoft's enterprise Copilot doesn't train on your data and respects your existing Microsoft 365 permissions. A user who can't normally access a document in SharePoint can't ask Copilot about it either. It only sees what the user sees.

Can Copilot replace writing staff / analysts?

No. Best case, it makes existing writers 20-30% more productive. It doesn't produce final-quality work without human editing, especially for anything regulated, legal, or client-facing.

Do I need Copilot to use ChatGPT at work?

No, they're separate. ChatGPT is OpenAI's consumer product. Microsoft Copilot is Microsoft's enterprise product, integrated into Microsoft 365 apps. You can use both, but for most SMBs on Microsoft 365, Copilot is the more practical choice — it has access to your own files, emails and meetings; ChatGPT doesn't.

Is there a free trial?

Microsoft typically offers short Copilot trials through resellers. Ask when you're buying — we can usually set one up.
