Microsoft 365 Prices Are Rising in July: How UK Businesses Can Lock In Current Rates and Master the New Copilot

Microsoft has confirmed that prices for the majority of Microsoft 365 plans will rise on 1 July 2026, with increases ranging from 8% to a staggering 33% depending on the licence tier. For UK small and medium-sized businesses, this represents one of the most significant cost adjustments since Microsoft's shift to subscription-based licensing. But here's the critical detail many IT managers are missing: if you renew your agreement before 30 June 2026, you can lock in today's pricing for up to 36 months. That's a saving window of just 78 days from today. At the same time, Microsoft is fundamentally restructuring how Copilot works across its Office applications, splitting AI capabilities into two distinct tiers from 15 April 2026. This guide breaks down exactly what's changing, what it costs, and what your business needs to do before the deadline.

What's Changing and When

Microsoft announced these global price adjustments in December 2025, giving organisations roughly six months' notice. The increases are not uniform — they vary considerably by plan, and two popular tiers are staying put entirely. Here's the full breakdown for UK businesses, with approximate GBP pricing per user per month:

Plan	Current Price	New Price (July 2026)	Increase	Effective Date
Microsoft 365 Business Basic	£4.60/user/mo	£5.40/user/mo	~17%	1 July 2026
Microsoft 365 Business Standard	£9.40/user/mo	£10.50/user/mo	~12%	1 July 2026
Microsoft 365 E3	£30.20/user/mo	£32.70/user/mo	~8.3%	1 July 2026
Microsoft 365 E1	£6.00/user/mo	£6.00/user/mo	No change	N/A
Microsoft 365 Business Premium	£17.60/user/mo	£17.60/user/mo	No change	N/A
Microsoft 365 F1 (Frontline)	£1.80/user/mo	£2.40/user/mo	~33%	1 July 2026
Microsoft 365 F3 (Frontline)	£6.10/user/mo	£8.10/user/mo	~33%	1 July 2026

The percentage impact varies enormously. Frontline workers — warehouse staff, retail employees, shift-based teams — face the sharpest hit at 33%. Meanwhile, enterprises on E3 see a more modest 8.3% uplift, partly offset by the inclusion of Defender for Office 365 Plan 1 at no extra charge. Notably, Business Premium and E1 remain completely untouched.

Price Increase by Plan

“Since our last pricing update, we have introduced over 1,100 new features and capabilities across security, compliance, AI, and collaboration — including Copilot Chat at no additional cost for all commercial subscribers. These adjustments reflect the tremendous value Microsoft 365 delivers to organisations worldwide.”

— Microsoft, December 2025 pricing announcement

It's worth noting that Microsoft's justification isn't without merit. The platform has genuinely expanded in scope since the last price adjustment. Copilot Chat is now embedded across Outlook, Teams, and the web experience for every subscriber. Defender for Office 365 Plan 1 — previously a paid add-on — is now bundled into E3 licences. Whether those additions justify a 33% increase for frontline workers, however, is a question each business will need to answer for itself.

The Golden Window: How to Lock In Current Pricing

Here's the most important strategic detail in this entire article: Microsoft's new pricing only kicks in at your first renewal after 1 July 2026. That means if your annual agreement renews on 15 August, you'll see the new prices then. But if you bring your renewal forward and complete it before 30 June, you lock in today's pricing for the entire agreement term — typically 12 months, but enterprise customers can secure 36-month commitments that protect pricing through to mid-2029.

The practical deadline is 20 June 2026. Microsoft and its partners need processing time, so leaving it until the final days of June is risky. The smartest approach is to begin conversations with your Microsoft partner or IT provider now, while there's still time to review your licence mix, adjust seat counts, and negotiate terms.

Renew Now vs. Wait: A Cost Comparison

To illustrate the financial impact, consider a UK business with 50 users on Microsoft 365 Business Standard. The numbers speak for themselves:

That's a difference of £1,980 over three years for just 50 users on a single plan. For organisations running multiple licence tiers across larger headcounts, the savings compound rapidly. A 150-person business running a mix of Business Standard and E3 could be looking at savings north of £8,000 over a 36-month lock-in.

There's also a hidden advantage for Business Premium customers. Since that tier isn't increasing, the cost gap between Business Standard (£10.50 after July) and Business Premium (£17.60) is now at its narrowest ever — just £7.10 per user per month. For that premium, you gain advanced endpoint security, Intune device management, Azure Information Protection, and conditional access policies. If security is on your roadmap, the upgrade has never been more cost-effective.

Copilot Is Splitting Into Two Tiers

While the pricing changes take effect in July, an equally significant shift is happening even sooner. From 15 April 2026, Microsoft is restructuring its Copilot offering into two clearly distinct tiers, and the free experience is becoming considerably more limited.

Until now, all Microsoft 365 subscribers have had access to Copilot Chat across the Office suite — a basic AI assistant embedded in Word, Excel, PowerPoint, Outlook, and Teams. That's changing. From mid-April, the free Copilot Chat experience will be restricted to secure AI chat, chat-first content creation, and Outlook integration (including inbox and calendar grounding). However, Copilot will no longer be available inside Word, Excel, PowerPoint, or OneNote unless you hold a paid Microsoft 365 Copilot licence.

Copilot Chat (Basic) vs. Microsoft 365 Copilot (Premium)

Here's a detailed comparison of what each tier includes from 15 April 2026 onwards:

Feature	Copilot Chat (Basic)	M365 Copilot (Premium)
Secure AI chat (web & Teams)	Included	Included
Chat-first content creation	Included	Included
Outlook integration (inbox/calendar)	Included	Included
Copilot in Word	Not available	Included
Copilot in Excel	Not available	Included
Copilot in PowerPoint	Not available	Included
Copilot in OneNote	Not available	Included
Copilot Cowork (multi-step tasks)	Not available	Included
Agent Mode (continuous refinement)	Not available	Included
GPT-5.2 powered responses	Standard model	GPT-5.2 enhanced
Memory & personalisation	Limited	Full personalisation
Additional cost	Included with M365	Paid add-on licence

This is a deliberate move by Microsoft to create a clear upgrade path. The basic Copilot Chat remains useful for quick questions and Outlook triage, but the productivity-transforming features — drafting documents in Word, analysing data in Excel, building presentations in PowerPoint — now sit firmly behind the premium paywall. For teams that have built workflows around these capabilities, the change could be jarring if not anticipated.

The New Copilot Features Worth Paying For

If your organisation is weighing the cost of a Microsoft 365 Copilot licence, it's worth understanding what the premium tier actually delivers in 2026. Microsoft has been shipping significant updates throughout the year, and several of these features represent genuine step changes in how knowledge workers interact with their tools.

Copilot Cowork

This is Microsoft's flagship Copilot update for 2026, and it fundamentally changes the interaction model. Rather than responding to individual prompts, Copilot Cowork allows you to delegate multi-step tasks that run in the background. You set objectives, define checkpoints, and Copilot plans the execution, works through each stage, and returns results for your review. Think of it as moving from a chatbot to a genuine digital colleague — one that can draft a quarterly report by pulling data from Excel, formatting it in Word, and building the accompanying presentation in PowerPoint, all whilst you focus on other work.

Agent Mode

Rolling out across core M365 applications, Agent Mode replaces the single-draft approach with continuous refinement. Instead of generating one response and waiting for further instructions, Copilot in Agent Mode iterates autonomously — refining tone, checking facts against your organisational data, and improving output quality through multiple passes. This is particularly powerful in Word and Outlook, where the difference between a first draft and a polished document can mean hours of manual editing.

Excel Copilot Enhancements

For data-driven organisations, the Excel improvements alone may justify the premium licence. Copilot in Excel can now autonomously clean datasets, identify anomalies, perform advanced calculations without requiring you to write formulas, and generate multi-page analytical reports. It's the kind of capability that previously required a dedicated data analyst or expensive third-party tools.

Feature Rollout and Maturity

These progress indicators reflect the current rollout status across Microsoft's global tenant base as of April 2026. Most features are in general availability or advanced rollout, with full completion expected by Q3 2026.

UK Business Adoption of AI-Powered Productivity Tools

According to recent industry surveys, approximately 65% of UK small and medium-sized businesses are either actively using Microsoft 365 Copilot or evaluating it for deployment in 2026. The shift from curiosity to adoption has accelerated markedly since GPT-5.2 began powering the platform, with organisations reporting measurable time savings in document creation, email management, and data analysis. For businesses still on the fence, the new Copilot Cowork and Agent Mode features may prove to be the tipping point.

Security Upgrades You're Getting Free

Amidst the pricing increases, Microsoft is quietly delivering significant security enhancements that deserve attention — particularly for organisations concerned about the rising threat landscape facing UK businesses.

The headline inclusion is Defender for Office 365 Plan 1, which is now bundled into Microsoft 365 E3 licences at no additional charge. Previously a paid add-on, Defender Plan 1 provides advanced anti-phishing protection, safe attachments scanning, safe links URL detonation, and real-time threat detection across email and collaboration tools. For E3 customers, this partially offsets the 8.3% price increase — you're genuinely getting more for your money.

Beyond Defender, Microsoft has strengthened its identity security capabilities across the board:

• Phishing-resistant authentication — passwordless sign-in methods and hardware security key support are now standard across all business tiers, reducing the risk of credential theft.
• Enhanced conditional access policies — more granular control over who can access what, from which devices, and under what conditions. This is particularly valuable for hybrid working environments.
• Strengthened monitoring and alerting — improved security dashboards and automated threat response capabilities, aligned with the Zero Trust security model that assumes no user or device is inherently trustworthy.
• Zero Trust architecture alignment — Microsoft's entire M365 security stack is now built around Zero Trust principles: verify explicitly, use least-privilege access, and assume breach. This is the security framework recommended by the UK's National Cyber Security Centre (NCSC).

For UK SMEs, particularly those handling sensitive client data or operating in regulated sectors, these security additions provide enterprise-grade protection that would cost significantly more to procure separately. It's a strong argument for E3 adoption — or at the very least, for reviewing whether your current security posture is adequate.

Your Action Plan Before July

With 78 days remaining before the new pricing takes effect, here's a step-by-step action plan to ensure your business is positioned to save money and take full advantage of the platform changes:

1. Audit your current Microsoft 365 licences immediately. Log into the Microsoft 365 admin centre and review every active subscription. Identify which plans you're on, how many seats you're paying for, and when your current agreement renews. Look for unused or underutilised licences that could be removed before renewal.
2. Calculate the financial impact of the price increase on your organisation. Use the pricing table above to determine exactly how much more you'll pay after July. For a business with 50 users on Business Standard, that's an additional £660 per year. Multiply across your actual licence mix and headcount for a precise figure.
3. Contact your Microsoft partner or IT provider before 20 June 2026. Initiate an early renewal conversation now. Discuss options for 12-month or 36-month commitments to lock in current pricing. Don't leave this until the last week of June — processing and paperwork take time.
4. Evaluate the Business Premium opportunity. With Business Premium holding steady at £17.60 and Business Standard rising to £10.50, the gap is just £7.10 per user. If your business needs advanced security, device management, or compliance tools, this is the most cost-effective time to upgrade.
5. Assess your Copilot usage and requirements. Review which team members are actively using Copilot in Word, Excel, and PowerPoint. From 15 April, they'll lose that access without a paid Copilot licence. Decide whether the premium features justify the investment for your key productivity users.
6. Review your security posture. If you're on E3, ensure your team is taking advantage of the newly included Defender for Office 365 Plan 1. If you're on a lower tier, consider whether the security additions in E3 warrant an upgrade, particularly if you handle sensitive data.
7. Plan your Copilot rollout strategy. If you're investing in premium Copilot licences, don't deploy them to everyone simultaneously. Start with power users in document-heavy or data-heavy roles, measure the productivity gains, and expand from there.
8. Document your decisions and set calendar reminders. Record your renewal date, the terms you've agreed, and the pricing locked in. Set reminders for 90 days before your next renewal to repeat this assessment process.

The July 2026 Microsoft 365 price increase is not a surprise — it's been telegraphed for months. But the difference between businesses that act now and those that wait could amount to thousands of pounds over the next three years. The golden window is open, the Copilot landscape is shifting, and the security upgrades are already landing. The organisations that treat this as an opportunity rather than an inconvenience will come out ahead: with lower costs, stronger security, and AI tools that genuinely transform how their teams work. The clock is ticking — 78 days and counting.
