Average retail prices for gasoline and diesel in the UK rose for the 20th consecutive week in the period ending July 4, data released Tuesday by the Department of Energy & Climate Change (DECC) showed.
In the week ending Monday, the average UK pump price of unleaded gasoline (ULSP) was 111.65p/liter, up 0.21 p/liter week on week.
The price of diesel (ULSD) was 112.86 p/liter, up 0.30 p/liter on the week.
Retail fuel prices last fell on a week-on-week basis on February 22, and are currently at their highest level since August.
In a separate statement, RAC fuel spokesman Simon Williams said: "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."
Wholesale gasoline and ULSD prices have been brought into focus since the UK's vote to leave the EU.
Imports into the UK are priced in US dollars, so sterling's sharp devaluation during the financial aftermath has the potential to have stark knock-on effects at the pump.
"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," Williams said.
