My comments relate to Deloitte but I doubt Accenture is significantly different. You can't just kick the @rse out of it by getting taxis everywhere, but it really depends on where you are going. If it is the most reasonable (or only option) then it will be fine. If you live in Zone 3, South London, and have to travel up to Zone 5, North London, tube/train would clearly be more reasonable. If you are in Bristol, then you will stay in a hotel in Bristol midweek and will probably take a taxi to the client every morning. Either way, costs are reimbursed.If as is likely the case you are going to be out of your base office for 6 months or more of the year I would strongly recommend you do not buy an annual travel card. A lot of your travel can be expensed and it would be a waste of money.As for reimbursement of actual expenses or payment of a per diem, it depends on the project. I've never had a per diem, although they do exist. There are generally limits on the amount you can claim for a meal. In the context of the cost of food in a hotel (usually poor value) the allowances are not particularly generous, but I've never really had any problems getting reimbursed. Depends on the policy of the engagement partner/manager but when you earning the firm over a thousand a day in fee he would have to be a bit of a knob to beat you up over going a fiver over the allowance. Again, it's just a question of not kicking the @rse out of it.It helps when the partner / manager also likes good living, and decent food and drink in the evening!
