Azure Plan Subscription without access to VM sizes to create AKS Cluster (UK South)

Hello @Ana Louro

Although the subscription is not a Free Trial, Azure is not offering any VM SKUs in UK South for the subscription. This is not a quota issue and not an AKS configuration issue.

The behavior is caused by region‑level compute capacity restrictions combined with subscription‑level SKU eligibility, which directly impacts AKS node pool creation.

1.When you create an AKS cluster, Azure checks two things before showing VM sizes:

1. Whether the VM family/SKU is allowed for the subscription
2. Whether capacity is available in the selected region and availability zones

2.In UK South, Microsoft frequently enforces temporary capacity restrictions, especially on:

• General purpose SKUs (DSv5/ESv5)
• Cost‑optimized SKUs
• New or smaller subscriptions under Azure Plan

When no VM family is both allowed and available, the portal shows:

“Not available for subscription” for all VM sizes.

• Request VM SKU Access for UK South :

This is the only permanent fix if you must deploy AKS in UK South.

Steps:

1. Go to Azure Portal
2. Open Help + Support → Create a support request
3. Choose:
   • Issue type: Service and subscription limits (quotas)
   • Quota type: Compute
   • Region: UK South
4. In the description, clearly mention:

VM sizes are showing "Not available for subscription" during AKS creation. This is blocking production AKS deployment in UK South. Requesting SKU access / capacity enablement for standard DSv5/ESv5 SKUs.

1. Submit the Request.

• Use a Different Region for AKS :

If production timelines are tight:

• Deploy AKS in West Europe or North Europe
• Keep supporting resources (ACR, Key Vault, Storage) in UK South if needed

This works because:

• VM capacity pools are region‑specific
• Your subscription is already eligible in other regions.

Final Conclusion :

If AKS must be deployed in UK South:

• Open a support request for VM SKU enablement
• Clearly state it is blocking AKS production deployment
