The chancellor has slashed fuel duty to help ease record prices facing motorists and businesses, but it could be some time before the cut is reflected at the pumps.
Rishi Sunak has told MPs in his spring statement that the 5p a litre cut for petrol was to take effect from 6pm this evening.
But fuel retailers said the move meant they faced taking a loss as the prices they pay to stock forecourt tanks already had fuel duty built in.
Meanwhile, some have called for a cut to VAT to help drivers instead, because VAT is applied at point of sale and so would have an immediate effect.
The fuel duty cut raises the prospect of a rise in prices at forecourts to account for the hit. Alternatively, experts say that retailers could absorb some or all of the duty cut themselves by not lowering their prices.
Gordon Balmer, executive director of the Petrol Retailers Association, explained: “Forecourt operators have purchased the fuel they are currently providing at the higher fuel duty rate.
“As a result, they must first deplete their stocks and resupply with fuel bought at a reduced rate before motorists will see a change in pump prices.”

The news comes as average fuel prices hit another record high this morning. Petrol is currently at £1.67 a litre, while diesel costs £1.79 a litre.
The cost of filling an average 55-litre family car with petrol is now more than £92 and nearly £99 for diesel. The £100 tank is now inevitable, according to the RAC.
“We’re pleased to see the Chancellor has given drivers some much-needed relief at the pumps, but the reality is that a 5p cut in duty is something of a drop in the ocean,” said RAC spokesperson Rod Dennis.
Reducing it by 5p will take prices back to where they were just over a week ago, Mr Dennis added.
In response to the announcement on Wednesday morning, Asda has said it will cut fuel prices by 6p per litre.
In a statement, the company said: “Following the announcement by the Chancellor of the Exchequer just now, Asda has confirmed it will pass the reduction in fuel duty announced in today’s spring statement straight on to its customers.
“The supermarket will reduce the price at the pumps by 6p per litre which includes a 1p reduction in VAT.
The RAC argued that cutting VAT would have been a preferable way to assist drivers.
“Temporarily reducing VAT would have been a more progressive way of helping drivers as the tax is applied at the point the fuel is sold, removing any possibility of retailers taking some of the tax cut themselves to increase their profits,” Mr Dennis said.
“It’s also the case that the Treasury is benefitting hugely from the high fuel prices because of greater VAT revenue. The Chancellor is currently getting 28p a litre VAT on petrol and 30p on diesel – this of course comes on top of fuel duty as VAT is a tax on a tax.”
