Hi, I suspect the companies travel and expense policy is similar. Often the policy will not be as generous for more junior grades.
UK companies tend to let you charge the actual costs of meals, travel etc up to a certain limit rather than giving you a daily per diem.
I've not worked for any of the companies you've mentioned however, I suspect that broadly the policy will be:
- Economy class flights, or if more than 4-6 hours Business Class (Accenture allows Business Class only if more than 8 hours and the person is SM or above)
- 4* hotel, Hilton etc or if you're unlucky Holiday Inn type standard
- standard class rail tickets
- £30 ish evening meal allowance
and a bunch of other stuff.
