simplified expenses - mileage

I am a sole trader and also in a partnership (totally separate trades). Both businesses did over 10,000 business miles during 2023/24. What mileage rates can be claimed? Can both claim for 10,000 @ 45p will the balance claimed at 25p or can only one business claim at 45p?

Hi,
Please have a look at the guidance at:
BIM75005 
Thank you.

HMRC, I had already looked at BIM75005 but it doesn't answer my question. That is why I posted on this forum. Your online guidance is too simplistic and doesn't cover scenarios like this one. Can you please answer my question?
