HS340 - Loan tax relief mortgage additional borrowing

My residential home which is owned with my wife. This currently has a mortgage on the house. I planned to take out further borrowings of £100,000 basically additional borrowings and then loan this money to my limited company. This would mean part 1 of the mortgage would have £150,000 (original mortgage) and part 2 of the mortgage the additional borrowing element would be £100,000 the amount loaned to my limited company. There would be two parts of the mortgage part 1 and part 2. Both have calculations for interest and repayment. My understanding is that with HS340 I could offset the interest of the loan, part 2 additional lending element.

Hi,
If you meet the conditions specified then yes. You may also want to refer to the HS204 that is mentioned:
