WATCH: Are petrol prices too high?

Founder of the Kent-based campaign group Fair Fuel UK, Howard Cox, said: "We're seeing prices at the pumps rocketing.

"The prices we're seeing increasing will impact badly on businesses, the haulage industry, low-income families, small businesses and white van men.

"That impacts on inflation and the economy.

"We've been calling for a pricing regulatory body.

"The most important thing here is that the motorists in the UK are the highest taxed in the world.

"Sixty-five per cent of everything that goes in to the tank goes to the government.

"I think we're looking at prices gradually increasing a little bit more.

"What will help is when supermarkets come in and bring discounting in if you buy so much in their shops."

Meanwhile, the RAC has called the news sad.

Spokesman for the motoring group, Simon Williams, said: "Sadly, December was the month oil reached its highest point for over two and a half years - something which motorists are now feeling the effect of at the pumps.

"On a brighter note, the shutdown of the North Sea Forties pipeline did not cause the price of oil to increase as many expected.

"It had been feared this would lead to petrol and diesel going up in the run-up to Christmas, but luckily for drivers global oil production was not negatively affected as a result.

"It's hard to see pump prices getting much cheaper in the early part of 2018.

"Unfortunately, the good times of lower cost fuel appear to be over and it's probably now far more likely that we will see them going up."

It is also thought the amount we pay at the pump will go up before it goes down.

Motoring editor at Confused.com, Amanda Stretton, said: "We can't blame drivers for resenting the fact they are now paying the highest prices for petrol since December 2014.

"Motorists are fed up of seeing the cost of owning and running a car go up every year.

"The main thing drivers can do to steer away from rising fuel prices is to research the cheapest place to fill up in their local area.

"Drivers should also try and drive more resourcefully, including driving at slower speeds, accelerating gradually, avoiding over-revving and using a higher gear."

A spokesman for petrolprices.com explained the reason the cheapest places to fill up are supermarkets is because they count on low prices getting people to shop in their stores.

The reason traders which just sell fuel, such as Esso and Jet, are not on the list is because they cannot afford to cut prices as much.
