Are there any places where you can, for example, just tank up and drive
off, and then later receive a bill in the post or have your bank account
linked to automatically take payment at the end of each month?

You would, naturally, need an account and would have to insert a card
into the pump for identification and to release the pump.

In the U.S. that's pretty common and known as fleet fueling. There's two flavors
- one is a private fueling center, the other uses standard retail fueling sites.
Both require the use of a card similar to a credit card. The price per unit can
be negotiated independently of the posted retail price, or based on a percentage
(+/-) of the current retail price.
