Tax deductibility of a loan

I have taken a small loan to refurbish a buy to let property, held in my name (not under a company) - is interest on the loan 100% deductible or just 20% deduction allowed?

Hi,
The following guidance confirms thst as long as the loan taken out is wholly and exclusively used for the rental business, this would be an allowable expense and would be declared in the “Loan interest and other financial costs” box.

Thank you.
