Microsoft 365 Licensing Changes in 2026 for London SMBs: New Prices & Deadlines

2026 is proving to be a reality check for IT decision-makers. Critical updates are coming together with dramatic price changes and hard-and-fast renewal terms. Microsoft has announced a worldwide price hike for July, along with tough changes to the New Commerce Experience terms for expirations. For businesses in the capital, managing the Microsoft 365 licensing changes in 2026 for London SMBs requires a proactive review of your current software licensing strategy. Do not wait for the invoice to arrive.

This is not a typical adjustment. It is a hard economic blow. The combination of price hikes, the removal of grace periods, and end-of-support deadlines creates a “perfect storm” for budget holders. IT managers who fail to prepare could see operational expenditure jump by double digits. This guide details exactly what is changing. It explains why it is happening. And it tells you how to protect your organisation’s bottom line.

The July 2026 Price Increase: What to Expect

Microsoft has clarified in its “Advancing Microsoft 365” update that specific Microsoft 365 plans will increase to the 1st of July 2026 due to additional benefits from Microsoft’s Copilot Chat, Defender for Office 365, and Intune. This will apply only to Business Basic, Business Standard, and Enterprise E3/E5 plans, not Business Premium, which will see no changes, thereby narrowing the price difference between Standard and Premium.

Estimated Price Impact (USD Baseline)

The table below indicates the confirmed percentage changes for the critical plans.

Note for UK businesses: Although the increases are global, Microsoft indexes local pricing to the US dollar, so your GBP (£) cost will depend on the exchange rate on the 1st of July 2026. Budget for the percentage rise below and add a small buffer for currency movements.

Plan Name	Change Status
Microsoft 365 Business Basic	Increase (~17%)
Microsoft 365 Business Standard	Increase (~12%)
Microsoft 365 Business Premium	No Change (0%)
Microsoft 365 E3	Increase (~8%)

Understanding the “Value” Justification

Microsoft says it can justify these increases by citing particular features that have been added since the last price rise:

• Business Basic & Standard: Now includes Copilot Chat (AI assistance embedded in apps) and Safe Links (URL security checks) to block malicious phishing sites.
• Enterprise E3: Now includes Defender for Office 365 Plan 1 (previously a paid add-on) and Intune Remote Help.

But take a typical London professional services firm. They utilise Outlook, Word, and Teams. For some businesses, these “added values” may be redundant. If users are not using the new security or AI features, the increase is simply a higher cost with no apparent benefit. This is why the audit process later in this article matters.

April 2026: The End of the ‘Grace Period’

The July increase may grab headlines, but the more significant operational change takes effect on the 1st of April 2026. Under the New Commerce Experience (NCE), Microsoft is removing the traditional “grace period” for expired subscriptions. Disorganised IT departments are the ones left exposed.

Previously, a missed payment or a renewal slip did not immediately cut off services; administrators had a short window to fix the issue. From April 2026, that safety net is gone.

The Extended Service Term (EST)

If you do not renew by the end date, the subscription moves into the Extended Service Term (EST). It is not free, and continued access is often billed at a premium monthly rate above your contracted price. “Doing nothing” now costs money, as when an administrator waits for finance approval to renew 50 Business Standard licences.

• Old Rule: The licences enter a 30-day grace period. Services continue. No extra cost.
• New Rule (April 2026): The business is immediately billed at the monthly NCE rate, typically 20% above the annual rate, once the licenses enter EST. Until the renewal is completed, there are surcharges.

Establish 90, 60, and 30 days before every NCE renewal date, maintain stringent renewal administration, and issue approvals much further in advance.

October 2026: Office LTSC 2021 End of Support

The third major date lands on the 13th of October 2026. That is when Mainstream Support ends for Office LTSC 2021 (Long Term Servicing Channel). Organisations still relying on perpetual, “one-off” Office purchases rather than cloud subscriptions are about to hit a wall.

Once it is no longer under support, the applications stop receiving security updates. In the hybrid world, a greater threat is connectivity: it is customary practice at Microsoft to block cloud access to unsupported software, e.g., an old Outlook client, to Exchange Online, which can cause inferior performance, or to block the entire computer. To ensure connectivity across the Microsoft 365 technology stack, there is only one rational direction for migrating to Microsoft 365 Apps for Enterprise.

The Hybrid Connectivity Risk

Many London SMBs run hybrid setups, keeping on-premises servers. If endpoints are running Office 2021, integration with Microsoft 365 email services may fail, creating a continuity and compliance risk. If Outlook cannot authenticate to Exchange Online because it does not support modern authentication, email access will stop, and there is no workaround.

Strategic Review: Beyond Just Office Apps

Budgeting for these changes means looking beyond the per-user cost of Word and Excel. Use the price rise as a catalyst: audit your infrastructure, then find savings in your server room or Azure environment to offset the higher Microsoft 365 bill.

Optimising Server Workloads

Many businesses run Windows Server or SQL Server on-premises without realising they have the right to move those licenses to the cloud. Do you possess Software Assurance? Investigate your eligibility for the Azure Hybrid Benefit. With this benefit, your existing on-premises licences can be used when running Azure Virtual Machines, lowering the rate you are charged. You could save up to 40 per cent on cloud infrastructure costs.

This licence cost is generally factored into the cost of an hourly Windows server running on Azure. There are no licence costs for Azure Hybrid Benefit. This saves hundreds of dollars per month, enough to pay for additional Microsoft 365 licences. It will save you money, whether you run your server 24/7.

Compliance Checks and SQL Licensing

During the audit, verify your SQL Server footprint. SQL Server licensing is complex, particularly in virtualised environments, and your architecture determines whether you license by core or by server plus CALs (Client Access Licences). London businesses are buying too many licenses (by purchasing Enterprise when Standard would suffice) and buying too few (by not licensing all virtual cores). Do this, and you will avoid punitive measures that will further exacerbate the effect of the 2026 price increases.

Reviewing User Personas

Assigning a premium SKU, for example, E3, to all users by default, just in case, is typically an over-allocation. This may look like a robust method, but often you are funding features in the higher product that most employees will not use. In fact, significant savings can be made without disrupting daily workflow by simply normalising the licensed allocations to end-user demand.

• Frontline Workers: Do reception staff or warehouse personnel need a desktop version of Excel? Often, a Frontline (F1 or F3) licence is sufficient. And significantly cheaper.
• Shared Mailboxes: Are you paying for a full licence for a generic “Info@” or “Sales@” mailbox? Stop. These can often be converted to Shared Mailboxes. They are free (up to 50GB storage) and do not require a user licence.

How London SMBs Can Mitigate the Impact

Do not accept higher costs passively. Several tactical moves can help London businesses absorb these changes efficiently, but to navigate the Microsoft 365 licensing changes in 2026, London SMBs must act before the deadlines.

• Renew Early: The most direct way to avoid the July 2026 price increase? Renew your annual NCE contracts before the 1st of July. Sign a new 12-month agreement in June 2026. You lock in the current pricing until June 2027. Effectively, you buy a one-year delay on the price hike.
• Audit “Zombie” Licences: Paying for what you have always had is not enough. Check your list of current users. You are wasting money if a staff member departed three months ago and their licence is still in effect. Take these chairs away. Before your renewal window ends, please do it.
• Consider the Upgrade: Business Standard is rising. Business Premium is staying flat. The cost difference is smaller than ever. Business Premium includes advanced security (Defender for Business) and device management (Intune). It may now be cheaper to upgrade to Premium than to pay for Standard plus third-party security add-ons from vendors like Sophos or Cisco.
• Switch to Annual Commitment: On a Monthly commitment? You are paying a 20 per cent premium for flexibility. Move to an Annual commitment to immediately reduce the baseline cost. You lose the ability to minimise seat counts mid-term, but for stable headcounts, the savings are substantial.

A Step-by-Step Licensing Audit

The London IT teams can use this audit workflow to prepare in time for July:

• Export User List: Extract an existing user list from the Microsoft 365 Admin Centre.
• If HR records do not match, cross-check the exported records against the HR starters and leavers report,s and flag any invalidities as soon as possible.
• Cleaner licensing decisions start with usage: check the date of the last activity on assigned licences, and if a person has not been using OneDrive or Teams within 90 days, one must wonder why they are given a full licence.
• Renewal dates matter. Go to the Partner Centre or your CSP portal, make sure you have the specific dates of your subscriptions to renew at NCE, then allow 30 days from those dates, and set your decision deadline 30 days before those dates.

Conclusion: Preparing for Microsoft 365 Licensing Changes in 2026 for London SMBs

Microsoft licensing has a 2026 watershed, with the April NCE rule changes, the July price hike, and the October support deadline coming one right after the other. Do not hold back till the renewal notice. Start the audit now.

Confirm the key dates, purge user lists, and determine whether a budget balance can be achieved by optimising server licensing. Manage risk, keep it under control, and seek efficiencies to bring your IT budget back to better health.
