Motorists are still paying a high price when they go and fill up their tanks.

It's back to school season which means you'll likely using more petrol on the school run or sitting in rush hour traffic - meaning it's paramount that you get a good deal when you fill up.

On average, the price of unleaded is 139.92p whilst diesel stands at 144.64p - but these prices are both 

This comes as watchdogs say retailers are overcharging customers as they urge them to "do the right thing" and lower their prices.

RAC head of policy Simon Williams said: “The biggest retailers’ refusal not to reduce their prices to fairer levels is continuing to cost drivers dear, and it’s all the more outrageous when you factor in the fact we’re all meant to be benefitting from a temporary 5p cut in fuel duty.

“While the Competition and Markets Authority has clearly stated drivers were overcharged last year, it’s blatantly apparent from our data that this problem is persisting this year.

“Once again, we urge retailers to do the right thing and reflect the lower prices they’re paying for wholesale fuel on their forecourts.

“It’s plain for all to see from some of the lower prices being charged around the UK, both across the whole of Northern Ireland and at various other forecourts, that fuel can and should be sold much more cheaply."
