Fuel prices fall 1.5p in 2025, reports RAC Fuel Watch
Fuel prices fell by around 2p a litre in December to reverse increases seen in November.
According to RAC Fuel Watch, petrol came down by 1.8p last month to 135.37p and diesel dropped 2.3p to 144.27p. This means both fuels finished 2025 about 1.5p lower than they began the year.
Meanwhile, throughout 2025 petrol has averaged 135.69p and diesel 142.96p, which is 6.5p and 5.7p less than 2024.
In Northern Ireland the average price of a litre of petrol is almost 8p lower than across the whole of the UK at 127.5p and diesel is nearly 9.5p less at 134.9p.
Even lower prices
RAC head of policy Simon Williams said: “After prices at the pumps fell by 2p a litre in December drivers are starting the new year paying 1.5p less than they were a year ago.
“But with oil tumbling below $60 a barrel in mid-December and recording its lowest monthly price in six years, it’s a shame drivers aren’t seeing even lower prices on forecourts up and down the UK. As wholesale fuel costs went below those that led to the cheapest prices of the year in June, we’d have hoped to see the year lows of 132p for petrol and 138p for diesel beaten.
“We hope that 2026 will see more competitive pump prices on the back of the government’s fuel finder scheme going live at the start of February and increasing competition.”
