The best thing used to be 'You Days' when you would get an additional one day off from work per month, but the worst thing is that this policy no longer exists. They reduced it to six days this year (for full time) and is at the discretion of senior management as to whether You Days would be offered in the future.
One of the great things is that the days between Christmas and New Years are annual days however they do not count against your annual leave.
Average Car allowance + Fuel Card, extra days off on top of annual leave.
