Motorists suffered the worst monthly rise in the average price of petrol in at least 18 years* with 6p a litre being added at the pumps in May, new RAC Fuel Watch data reveals.
Unleaded shot up from 123.43p to 129.41p, taking the cost of filling up a 55-litre family car to £71.18 – an increase of £3.29 in just one month.
While the average price of a litre of diesel endured a slightly greater monthly increase of 6.12p – from 126.27p to 132.39p – it was the second worst rise since the start of 2000, as it was fortunately some way behind the 8.43p increase seen 10 years ago in May 2008 (120.83p to 129.26p). The May 2018 rise has made the cost of a tank of diesel for a family car £3.37 more expensive at £72.81.
The RAC Fuel Watch data also shows the average prices of both petrol and diesel have gone up every single day since 22 April, adding 8p a litre in the process – the longest sustained price increase since March 2015.
In May the big four supermarkets raised petrol by 5.49p a litre and diesel by 5.88p while on the motorway, service stations added 6.37p to unleaded, taking it to 144.75p a litre, and 6.69p to diesel making it an eye-watering 147.80p a litre – 15p a litre above average UK prices for both fuels.
The forecourt increases have been driven by a jump in the price of oil, coupled with a weakening of the pound against the dollar. Oil broke through the $80 a barrel mark twice in May – something which has not been seen for three and a half years (since 12 November 2014).
Overall, May saw a 3% increase in the price of a barrel of oil (from $74.31 to $76.39) and a 2% drop in the value of the pound against the dollar ($1.35 to $1.33), making the wholesale price for retailers more expensive as fuel, like oil, is traded in dollars.
RAC fuel spokesman Simon Williams said: “May was a hellish month for motorists. Sadly, they have been besieged by pump price rises for three months with nearly 9p a litre being added to petrol since the beginning of March.
“The rising oil price together with a weaker pound is a punitive combination for anyone that drives regularly. For many people there is little alternative to the car for the majority of journeys they have to make so it is therefore very difficult to avoid feeling the pinch of rising pump prices.
“In the last week of May the oil price cooled a little to $76 a barrel which is slightly better news for motorists as the RAC’s two-week forecast is currently showing that average prices may even reduce by a penny or so. While this isn’t much, and could easily change in response to oil trading this week, it is at least a sign that the constant rise in forecourt prices may have stopped for the time being.
“Looking at the bigger picture, there is talk that OPEC – the Organization of the Petroleum Exporting Countries – may agree at its meeting on 22 June in Vienna to change its tack of restricting oil supply. The group, together with Russia, have been limiting production with a view to removing the long-term oil glut. This strategy has been successful and, as intended, caused the barrel price to rise. If a decision is taken to increase supply it may provide some much-needed relief for motorists at the pumps in the UK.”
Regional fuel price variation
The North West experienced the biggest rise in petrol prices with a litre going up 5.98p in May to 128.72p. Northern Ireland saw the smallest increase at 5.07p a litre, although unusually their unleaded was not the cheapest in the UK as that honour went instead to the North East with a litre costing 128.24p at the end of May. The South East once again was the most expensive place to buy petrol with a litre averaging 129.83p.
Looking at diesel, drivers in Wales endured the greatest increase on the forecourt with a litre jumping by 6.07p to 132.03p. The North East and South East had the smallest rise at 5.66p, but a litre of diesel in the South East is the most expensive in the UK at 132.73p.
