Hi
Thank you for your question.
As long as the repairs and refurbishments were used wholly and exclusively for the rental business then they would qualify as revenue expenses and can be claimed against rental profits.
The costs of the repairs can be claimed within the SA105 supplementary page.
Further guidance is available at:
Deductions: general rules
and
Deductions: repairs: is it capital?
The loan interest and any loan arrangement fees are allowable as a deduction.
This can be claimed separately within the SA105 supplementary page.
The capital element is not deductible.
