I'm also working from home and spend a lot of time travelling on the road. As "emul"'s suggestion my company covered the cost of office equipment, line rental, broadband and furniture. My expenses are still forwarded to the company where they are dealt with. What I did want to say to you is that the Revenue will make a % deduction from your annual electricity and heating bill on the basis of having a home office. They advised me that this is limited to a maximum % (only suggested to me that 6 - 7% is the normal claim) and that it is absolutely necessary that you identify a specific room in the house dedicated to the home office. The idea was then to measure this room and try to equate how much electricity/heat this utilises from the standard bill. So keep those bill receipts and you should be able to make a claim.
