Tax overpay for 2023/24 due to late service charge adjustment notification after tax payment

My daughter has submitted and paid the tax for 2023/24 in early Sep 2024 which covered tax payable for rental income for her property. Management company in late Sep issued a letter staying that as the actual cost of providing the service during 2023/24 is higher then budget, they charged an additional final balance of £718 for the service charge for 23/24. As the deductible expenditure in 2023/24 should be higher then the submitted figure while the property is now used for self occupation after April 2024, how my daughter could claim back the overpaid property tax for 2023/24.
