Graphic: It’s payback time at the pumps, as fuel prices tumble in Norwich.

Drivers are finally getting a feel-good factor on the forecourts, with fuel prices in East Anglia falling faster than anywhere else in the UK.

Pump prices across the country have fallen by more than two pence per litre (ppl) this month. On average, we now pay 127.2 ppl for unleaded and 131.3 ppl for diesel.

But a Norwich Evening News snap survey found Sainsburys on Queens Road in Norwich was charging 123.9 ppl for unleaded and 126.9 ppl for diesel, while other outlets were up to four ppl more expensive.

And elsewhere in East Anglia, petrol prices have fallen by 2.4 ppl, to a regional average of 127.3 ppl, while diesel prices have fallen 2.6 ppl to 131.4 ppl.

While pump prices are being driven down by falling oil prices and the weak pound, drivers in Norfolk, Suffolk and Cambridgeshire are still paying fractionally more for their fuel.

'It's a bit of a postcode lottery,' said Paul Watters, the AA's head of roads policy. 'You have a lot of smaller retailers there [in East Anglia], who will charge quite a bit more to stay in business.

'And you haven't got many Asdas and Morrisons in your smaller towns.'

Mr Watters said prices were predicted to plummet by six pence between Mid September and the end of this month. He said the fall put prices on a par with 2010, prior to increases in VAT and fuel duty which kicked in on January 1, 2011, adding 3.5p to the cost of a litre overnight.

'If it carries on all year, it could mean £60 benefit on a full tank but it won't last,' he warned. 'Fuel prices are a roller coaster.'
