Petrol prices edged up for the fourth consecutive month in June, according to the latest data from the RAC.
It says unleaded prices went up by 1.5p a litre in June, from 110.69p to 112.17p, while diesel rose by 1.66p a litre, up from 110.73p to 112.39p.
The forecourt price rise means the cost of filling an average petrol family car has increased by 81p over the month to £61.69, while the cost of filling a diesel car has risen by 91p to £61.81.
However, the RAC says despite the 11% post-referendum fall in the value of the pound, wholesale petrol prices have largely been unaffected due to a simultaneous 6% drop in the price of oil.

RAC fuel spokesman Simon Williams says: "June was another bad month for motorists with the price of petrol going up again. While it was only a penny and a half it makes for a rise of more than 10p since the start of March. Filling up with unleaded is now £5.64 more expensive which is enough to make an unpleasant dent in household budgets up and down the country, especially for those who have more than one car or need to fill up regularly.
“But it is good news that fuel prices are so far weathering the Brexit storm; wholesale prices have remained relatively stable after an initial small upward jolt as a result of the pound falling on news of the referendum result. The fact the oil price dropped at the same time lessened the negative effect of the pound’s devaluation. We may well see pump prices rise slightly in July, but current indications are that this is unlikely to be the shock rise some were predicting.”
