Tax allowable expenses for the Self Employed

Hi There

I am newly self employed working from an office in my house.

Just wonering if I can offset some off my household bills (as working from home) against my tax liability, ie ESB, Gas, Phone, Internet, and if so what %?

Secondly I bought a car 2 years ago, for which I am still paying a loan, about 60% of the use of the car relates to my new business. Can I offset any of the loan, petrol, tax, insurance, repairs etc again my tax bill?

Any advice / guidance would be much appreciated!

Thanks
