Tesco and Morrisons announced yesterday (27 July) that they would cut the price of diesel by up to 2ppl across their networks, with Sainsbury's set to make the same reduction across its 300 forecourts as of today (28 July). 

The latest cuts come just eight days after Tesco, Sainsbury's, Morrisons and Asda announced 2ppl cuts while Asda also announced that it was capping the cost of diesel at 112.7ppl.

In response, RAC fuel spokesman Simon Williams said: “Millions of private and business motorists that depend on diesel vehicles will be pleased with this latest price cut from the supermarkets.

“However, not every motorist in the country is yet to benefit from the fall in the diesel wholesale price – the average price of diesel sold at the pumps is still higher than petrol, despite diesel being bought in by retailers for less than the price of unleaded since the end of May.

“We expect the diesel/petrol average price ‘flip’ to come about in the coming days, and when it does there will be huge pressure on all retailers in the UK to sell diesel for less than petrol, reflecting more closely the wholesale price.”
