I am currently setting up a new business (self employed) which will require the purchase and regular use of a transit van. After reading a variety of documents ... I am confused about one thing. Can I claim all of the following: 1. Diesel/Petrol expense (as and when it is a legitimate business expense) and 2. Mileage allowance (as per IR guidelines) and 3. Capital depreciation of the Van plus 4. Other expenses such as insurance, MOT etc Thanks for any replies. Sean
