Having enjoyed the fifth monthly decrease in the overall price of fuel in July, drivers were sad to see the trend break in August, when the overall price of both diesel and unleaded petrol rose. This is the first increase on the average monthly price since February this year.

For unleaded, the average cost across the UK was 116.5 pence per litre in August. The average price for diesel was slightly higher, at 117.4 pence per litre. In both cases, the amount of fuel duty included per litre remains unchanged, at 57.9p per litre. This has been at the same rate since March 2011. The increase looks to be mostly due to seasonal factors, with many people holidaying during this month. There was also a slight increase in the cost of crude oil, which finished the month on the £40 per barrel mark.

Looking back over the last decade, the price of fuel has varied greatly, with the price in August 2007 standing at 97.0 pence per litre for diesel and 96.1 pence for unleaded.

Continuing to rise?

Fears are that prices could continue to rise, as the effect of Hurricane Harvey on the oil producing areas of the USA impacts on the global market. Originally, experts believed that prices going into the end of this year and the start of 2018 would rise only marginally. However, we will have to wait and see in September what affect this terrible natural event has on oil and fuel prices around the world.
