Renting a flat - what about bills and council tax?

So that's it? You basically get a slap on the wrist and pay it back?
I assume that's on a expense by expense basis as well.

Correct. Unless of course they thought that it was something other than a genuine mistake. At that point it's evasion/fraud.
From people I know who've been investigated it's the little signs that start them digging. Even if it's a genuine mistake as there are liekly to be many, many more 'genuine' mistakes.

But like the Isle of Man "retain 90% of your money" schemes, it's about your own risk appetite.

Have you asked your accountant what he says?

For the record.... your stay overnight when your car broke down is classed as business travel.... so no problemo...
