The average price of a litre of diesel and petrol at UK filling stations fell by more than 3p per litre during June, according to the RAC.
The motoring organisation said the new diesel price average of 150.13p per litre was down from 153.74p at the start of the month, while petrol was down from 148p to just under 145p.
However, despite the wholesale price of fuel also having risen slightly during the month, the RAC said that diesel should still be 8p per litre cheaper across England, Scotland, and Wales, and petrol 4.5p cheaper.
RAC head of policy Simon Williams said: “While it’s good news prices at the pumps have fallen for the second month in a row, this also leaves a bad taste in the mouth because we know drivers in Great Britain are continuing to get a raw deal as both petrol and diesel are still much more expensive than in Northern Ireland.
“This month’s Fuel Watch report also reveals just how expensive fuel is when bought at forecourts owned and run by oil giants Shell and BP. We remain baffled how the very same fuel can be sold for such vastly different prices by the biggest retailers, whether they’re run by supermarkets or the world’s largest oil companies.
“It’s also the case that while oil has increased from under $80 at the start of June to the mid-$80s by the end, wholesale costs are still low enough to merit cheaper prices at the pumps. Looking at the fairer average prices charged in Northern Ireland, petrol should be 4.5p lower across England, Scotland and Wales and diesel should be a whole 8p less.
“We will continue to highlight this disparity, along with the massive differences between major retailers’ high and low prices, to the new government and the Competition and Markets Authority with a view to them being addressed by the new Pumpwatch scheme when it is up and running.”
