I have signed up to quickbooks UK version – who knows how – and I need a CAD account. I can't register with my email as it's tied to the UK one. How do I just delete everything and start again?

Thanks for checking in with us, ashleyajardine.

You don't need to start from scratch. We can reuse the lists from your old company by moving your lists to a new company file. Follow these steps to cancel your account if you bought QuickBooks Self-Employed directly from QuickBooks or Intuit: 

1. Sign in to QuickBooks Self-Employed in a web browser.
2. Select the Gear ⚙ icon.
3. Select Billing Info and then Cancel subscription.

For more details about this one, see the Cancel your QuickBooks Self-Employed subscription article. Then, sign up for a new account. You can use the same user ID and password that you did previously. If you are using the QuickBooks Online version, see the Delete your data and start over in the QuickBooks Online article for more details. 

If the same thing happens, contact our QuickBooks Self-Employed Support Team. They'll pull u your account in a secure environment and help you with this one.

I'd like to know how things going after contacting our support agent, as I want to ensure this is resolved for you. Feel free to reply to this post and I'll get back to you. Take care always.
