This post is part of the New Functionality In Microsoft Dynamics 365 Business Central 2025 Wave 1 series in which I am taking a look at the new functionality introduced in Microsoft Dynamics 365 Business Central 2025 Wave 1.
The 7th of the new functionality in the Country and regional section is install UK localization as an extension to the base app.
The upgraded localized version for the United Kingdom is delivered as an extension.
Country-based customizations have been removed from the base app to help organizations save time and money during implementation. This change benefits organizations operating in multiple regions with different regulations by allowing easy building of PTEs and connecting environments. Delocalization also helps organizations access ISV solutions without restrictions.
Enabled for: Admins, makers, marketers, or analysts, automatically
Public Preview: Sep 2025
General Availability: Oct 2025
Feature Details
The localized version for the UK is now available as a set of extensions on the W1 base app. This includes a data upgrade to ease the transition from the previous localization. This release is a step toward full delocalization, allowing ISVs to reach a broader market. During this process, some features will move to the base app or be delivered as global apps, while others will remain specific to the GB market.
My Opinion
I can see how this would be a benefit, but I do worry about how well the “data upgrade” element will be and how smoothly the change will prove to be in reality.
