A study of the UK petrol and diesel market by the Office of Fair Trading (OFT) has said little action is needed.

"The evidence gathered by the OFT suggests that at a national level, competition is working well in the UK road fuel sector," its report said.

It found the UK has some of Europe's cheapest fuel prices before tax.

I'm always amazed. I live in Derby, about as far as you can get from the refineries on the coast, but I've yet to find cheaper petrol elsewhere. Everywhere is the same or a couple of pence more expensive in major towns. In the sticks, it's a lot more expensive.

The BBC's fuel calculator (clicky) shows just how much tax we pay. The petrol itself is dirt cheap.
