Drivers in the UK say they are still waiting for a fuel cut as their local petrol stations appear not to have reduced prices in line with Chancellor Rishi Sunak’s announcement.

Mr Sunak said fuel duty would be reduced by 5p per litre from 6pm on Wednesday, however some customers reported prices rising instead of dropping.

“My local garage has put the price of diesel up by 2p a litre since yesterday. They obviously never got the memo,” @matt76smith wrote on Twitter on Wednesday evening.

Meanwhile @aka_Titch tweeted on Thursday: “OK, so I went to fill up this morning thinking fuel prices will be 5p cheaper. All the prices have gone up by 5p overnight, Diesel was 179.9 buts it’s now 184.9”.

Louise Ali, 39, from Haslemere in Surrey, said a member of staff at her garage was “very much clueless” about whether or not their prices were going to fall.

“I’m really angry to be honest,” she told the PA news agency.

“Some stuff that Rishi said on the surface felt like it was a really good move. But in the case of petrol, what is the good of it if the actual companies owning the petrol stations aren’t going to pass on the reduction?

“I like to hope that there’s going to be something in place where they enforce that, but I don’t know if they can.”

Mrs Ali said she was passing her local petrol station on Wednesday and took a photo of the prices. Revisiting the site on Thursday morning, the cost of unleaded and diesel remained the same.

“I was just like, well, this is an absolute joke – you’ve had overnight to sort this out,” she said.

“And so I went in, I said to the guy ‘what happened? I thought the announcement was it was supposed to be from 6pm? And he was just like, ‘Yeah, that’s what I thought too.’

“He was very much clueless to the thing.”

AA president Edmund King said: “The AA welcomes the cut in fuel duty. However, we are concerned that the benefit will be lost unless retailers pass it on and reflect a fair price at the pumps.

“The Chancellor has ridden to the rescue of UK families and businesses who use their vehicles, not for pleasure, but to function in their daily lives.

“Since the start of the year, the 20p-a-litre surge in pump prices has been the shock that rocked the finances of families, and particularly young drivers, pensioners and lower-income workers who need to commute each day.”

Mrs Ali spent around £70 filling her car with unleaded, and said she would be following the price changes – or lack of – closely.

She said: “I’m definitely going to be keeping an eye on it. I started looking at it as a bit of fun yesterday, as I said, but now it’s kind of got my back up.”
