Drivers are now paying the lowest price for petrol since early July 2021, while diesel, which also came down by 2p, has gone below 139p for the first time since 28 September 2021.

The cost of a litre of petrol reduced from 134p at the start of May to 132.3p by the close, while diesel dropped from 140.5p to 138.4p.

A full petrol fill-up now costs £72.74 for a 55-litre tank vehicle, while diesel is £76.13. This means unleaded has decreased by more than 7p since the end of February (from 139.65p) and diesel by 8p (from 146.5p), saving drivers around £4 per tank.

A litre of supermarket unleaded is now down to 129p and diesel to 135p, both 3p lower than the UK averages.

In Northern Ireland, however, the average price a driver pays for a litre of petrol is even lower at 126.5p – nearly 6p cheaper than the UK average. Diesel is 130.8p – nearly 8p cheaper than the average UK price.

Sainsbury’s Shorehead store at Southgate in Huddersfield currently has some of the lowest pump prices, with a litre of petrol just 121.9p.

Asda’s forecourt on Western Road in Park Royal, London, is not far off at 122.7p, while Tesco is priced at 123.9p, less than three miles away at Western Avenue in Greenford.
