5. Home insurance (where an additional premium has been paid due to cover for an home office)
This really speaks for itself as the additional premium has been incurred solely due to the fact that you are running a business from your home and it is therefore quite clearly a business expense. However, this is something that people often forget to consider. It is worth reviewing the terms of your home insurance policies when you are considering setting up a home office as many policies can be made void if you operate a business from your home without informing your insurance company.
