Correct. You will also not be able to complete the form until you have the statement from the Spanish tax office stating you are a fiscal resident. You will not become a fiscal resident until you have spent more than 6 months in any one calendar year in Spain and have completed your first tax return.
You say you are moving at the end of July therefore you will not be a tax resident in Spain this year. You will only become a tax resident in Spain next year (2024) and complete your first tax return by June 2025 for income received in 2024. The tax office will then have you on their books and will supply the statement.
This is, unfortunately, the way it works and you will continue paying tax in UK for the remainder of this year and all of next year but will get the amount reimbursed once you have all the correct paperwork.
When we moved over, I informed the tax office by letter but all they did was send me the Spain individual (was then called a FD9 I think) and it took me a good 3 years to get it all sorted but I did get the tax I'd paid in UK refunded.
