For Home Office claimable rent for self-employment, is it the total rent of the property or exclusively my share? I live with roommates and pay a portion of the total.

You can only claim the share you pay for.

Thanks very much, Ginette!

Does the same apply for all fields in this category (Insurance, Electricity, Heating, Internet) or are these values the total for the house?

The amount of expenses that are claimable are always only about the amount you pay and then the percentage you are truly using for the employment.
