CGT profit and loss in the same tax year

I have a client who is completing on the sale of a property imminently on which there will be CGT due. The client is also marketing a second property where there will be a capital loss but which will not complete within the 60 day reporting period for the first property so will have to be declared separately. If the client has paid the CGT on the first property, can he get an in-year refund for the loss on the second property or does he have to wait until his SA return is submitted after 5/4/25?

Hi,
As the loss is after the gain, he will need to wait until after 05 April 2025
Thank you.
