Live in landlord - Allowable expenses

[heyjerome]

Good afternoon,

I'm a live in landlord and rent out 3 of my 4 rooms.

I was trying to clarify my tax calculation and I am one of four living in the house.

Is this right?

Allowable expenses:

All mortgage interest (not 3/4)

All buildings insurance (not 3/4)

3/4 Electric and gas

3/4 TV licence

3/4 Council tax

3/4 Water

10% of net rent for maintanance and repair = (rent - 3/4Bills)*10%

or can I claim all of the bills against the income?

Thanks for the help!
