Copilot and Fabric news, 16 October 2026: Copilot billing moves to 1 December
Easy Insight Team ·
Microsoft has pushed default usage-based billing for new Copilot Business licences bought through a partner back a month, to 1 December 2026. From the same date Copilot can be bought without a Microsoft 365 base licence. Fabric gets a partner discount of up to 20% for newcomers, and the ICO has opened a call for evidence on AI agents.
This covers 26 September to 16 October. FabCon Europe had its own event analysis on 9 October, and the Power BI October feature summary will anchor our first-Friday update on 6 November.
When does Copilot usage-based billing actually start?
1 December 2026, not 2 November. Our 25 September news reported the November date from Microsoft's partner announcement; Microsoft has since moved it. Its October partner announcements, updated 14 October, say pay-as-you-go billing will be on by default for new Microsoft 365 Copilot Business licences bought through a Cloud Solution Provider from 1 December.
Three details matter for a small business:
- The default cap is generous. The default spending limit is 4,000 Copilot Credits per user per month. A ten-person team could therefore run up to 40,000 credits a month before anything stops it, and it pays for what it uses.
- The UK is in the first wave. Microsoft lists the markets where the change will initially not be available; the UK is not among them.
- The controls already exist. Microsoft's Copilot Credits documentation describes a Cost management dashboard in the Microsoft 365 admin center with organisation and per-user limits, alerts and a choice of which services each policy covers. Its "Auto-apply new services" setting is on by default, so new agents join an existing policy automatically.
Our view: if you are buying Copilot Business through your IT partner before December, ask them to set a spending limit you chose, not the default, and decide whether new services should join automatically.
Will Copilot still need a Microsoft 365 licence?
To buy, no. From 1 December 2026, new Microsoft 365 Copilot and Copilot Business offers can be bought without a qualifying Microsoft 365 base subscription, across all channels and at the same price as today (Microsoft, 14 October). From today, 16 October, the current offers carry "(add-on)" in their names, and they stop being sold through partners on 1 December. Existing subscriptions need no action and can still be renewed.
Microsoft is clear that this changes how Copilot is bought, not what it does: Copilot still depends on the Microsoft 365 apps a customer is licensed for. Our Power BI licensing guide explains where Copilot sits alongside Pro and Fabric capacity.
Is Fabric getting cheaper?
For some newcomers, through a partner. The same announcements list Azure promotions for partners from 2 November 2026, including up to 20% off Microsoft Fabric pay-as-you-go capacity for eligible Microsoft 365 customers new to Fabric, and the same for Azure database customers with no prior Fabric spend. Eligibility, terms and the redemption window are Microsoft's.
For scale: 20% off the F2 pay-as-you-go list price in our Fabric pricing guide, about £231 a month in UK South as of October 2026, would bring it to roughly £185. That is our arithmetic, not a quote. A one-year reservation is still about 40% cheaper than pay-as-you-go at those rates, so for an always-on capacity the promotion does not beat it. It helps most while you are still pausing a small capacity out of hours.
What is the ICO asking about AI agents?
On 8 October the ICO opened a call for evidence on agentic AI, closing on 20 November 2026. It covers data security, transparency, accountability, automated decision-making, fairness and lawful processing, and the ICO says responses will show it where to give more clarity before it publishes final guidance.
It lands just as agent-style services such as Copilot Cowork move onto usage-based billing. If you are planning one, our GDPR and AI checklist covers the DPIA and automated decision-making questions to answer first.
What else changed?
- Office LTSC 2021: support for Office, Project and Visio LTSC 2021 ended on 13 October 2026, as we flagged in September. Microsoft confirmed it on 15 October; any remaining installs no longer get security fixes.
- ADBC drivers: Microsoft's transition page still plans to start switching the ADBC tenant setting on by default, in phases, during October 2026. Check the admin portal setting and test one Snowflake, BigQuery or Databricks report.
What we would do this week
Ask your IT partner how they will set Copilot spending limits before 1 December; if Fabric is on your list, ask whether you qualify for the promotion; and if an AI agent is on the roadmap, read the ICO's questions now.
If you want help with any of it, our AI strategy service covers Copilot rollouts and governance, and the AI practice and Power BI consultancy pages explain how we work.
Frequently asked questions
When does usage-based billing become the default for Copilot Business?
As of 14 October 2026, Microsoft says usage-based billing will be on by default for new Microsoft 365 Copilot Business licences bought through a Cloud Solution Provider from 1 December 2026, not 2 November as first announced. The default spending limit is 4,000 Copilot Credits per user per month, and admins can change it.
Will Microsoft 365 Copilot still need a Microsoft 365 licence?
Not to buy it. From 1 December 2026, new Microsoft 365 Copilot and Copilot Business offers can be bought without a qualifying Microsoft 365 base subscription, at the same price as today. Copilot still works across the Microsoft 365 apps you are licensed for, so the apps still matter.
Who qualifies for the Microsoft Fabric promotion?
Microsoft's October 2026 partner announcement describes up to 20% off Fabric pay-as-you-go capacity for eligible Microsoft 365 customers new to Fabric, and for Azure database customers with no prior Fabric spend. It runs through Cloud Solution Provider partners from 2 November 2026, subject to eligibility and terms.
When does the ICO's agentic AI call for evidence close?
It opened on 8 October 2026 and closes on 20 November 2026. The ICO wants evidence on how data protection law applies to AI agents, covering security, transparency, accountability, automated decision-making, fairness and lawful processing, to shape its forthcoming guidance.
