So the average price for petrol is now £1 a litre according to researchers Catalyst. The 10p rise for diesel will now mean that some businesses have to spend an extra £3000 on it.
The rise is because crude oil in America has reached $100 a barrel, and the global markets concerns over the weak dollar and shortage of winter fuel.
Compared to this time last year, the average motorist now has to pay amost £7 more to fill up their petrol tank, meaning that those families with two cars are now spending around £30 a month more.
Wife and mother of one, Sam Brown, 26, says she has found a new alternative to buying her petrol in the UK. She said: "I have been buying my petrol direct over the internet. Because it's not UK sourced, you don't have to pay UK tax."
But another member of the public, Mark Adams, 30, doesn't really think the rise will affect him much. "For most people fuel rises don't actually make much difference, my fuel has only gone up a couple of quid a week . I drive 12 miles a day, and it's still cheaper than public transport for me. Petrol prices are up and down like a yoyo, they may have gone up a couple of pence now, but they will go down again. For most people it's really not worth kicking up a fuss about."
Head of AA road safety, Andrew Howard said, "More and more retailers are accepting that they have to break through the psychological £1 per litre barrier.
"It is likely that with the average now through the barrier more rises will follow.
"This, coupled with steadily rising prices on the world oil markets, mean that relief for the British motorist is unlikely in the near future."

Petrol prices don't affect me as yet, as i have not yet passed my driving test, but i hope to be driving in a years time. I just wonder how much the average litre of petrol is going to cost then?
