Hi Bilal, thanks for joining the Community
We don't offer any courses or certification for QuickBooks Desktop in the UK. QuickBooks Desktop services (including all versions of QuickBooks Desktop Pro, Premier and Enterprise) were discontinued for UK users in June 2023 along with support, meaning that certification isn't something that we'll be introducing in the future.
If you're thinking about moving to QuickBooks Online, we have a range of live and on-demand webinars to help you learn as you go.
