Why can't I delete an appointment?
If you have raised an invoice for an appointment, you won't be able to delete it from the diary.
We do this for your protection so that your diary matches the information on the associated invoice. If we didn't do this, HMRC would likely to take a dim view of your record keeping.
Example: HMRC audit your invoices and do a simple cross-check between the appointments listed on one of your invoice and your diary. A discrepancy between what's on the invoice and your diary will give cause for concern at the very least and may prolong your audit - not something you want, rest assured!
When you click on an appointment in the diary and an invoice has been raised for it already, you won't see the delete icon at the bottom right.
In order to delete the appointment, you'll need to delete the invoice first. You can access the invoice by clicking on the invoice icon at the top right. This icon will be black if the invoice is not paid:

And green if it has been paid:
