According to the RAC, the average price of unleaded petrol has risen by around 5p to 137.5p per litre, while diesel has jumped 9p to about 151p per litre since the latest escalation in the region at the end of February.
Experts warn prices could keep rising if oil remains above $100 a barrel, potentially pushing petrol towards 150p per litre and diesel close to 180p.
RAC head of policy Simon Williams said: “Average petrol and diesel prices have rocketed in the last week and are unfortunately likely to keep on rising.
“We encourage drivers to continue filling up as normal but to shop around for the best prices using apps like myRAC as there can be big local differences between forecourts.
“Driving fuel efficiently by avoiding harsh accelerating and braking and ensuring tyres are inflated to the right pressures can help eke out every last mile and save money.”
