Full list of towns & cities where petrol is 10p-a-litre cheaper than the UK average – how does your area compare?

, motorists in Colerain, Northern Ireland, were ranked the luckiest - pocketing around £7.48 at a Sainsbury's station boasting unleaded petrol at 140.9p per litre.

This comes in a staggering 13.6p less than the UK average which currently sits at an eye-watering 154.5p.

Meanwhile, drivers in Hastings, East Sussex, will be thrilled to hear they can top up their tanks at the second cheapest garages.

They include a Sainsbury's offering 143.9p per litre, an Esso and Texaco both charging 144.9p per litre and finally a Jet forecourt with prices at 144.9p per litre.

According to the data, Sainsbury's proved to be a common winner, placing third, fourth and fifth on the list in Peterborough, Wantage, Oxfordshire and Liverpool.

Elsewhere in the UK, another East Sussex victory was claimed in Battle where an Esso garage boasted 144.9p per litre.

The same price was found in another one of the company's branches in Bridgend, Wales and in Newton-Le-Willows, Merseyside.

Sainsbury's mirrored the deal in Kettering, Northampton, Cannock in Staffordshire, Devon's Torquay and Strathaven in Lanarkshire.

And, the supermarket giant also provided the eight cheapest Diesel prices in the UK.

Forecourts in Wrexham, Whitby, Huddersfield were ranked the top three with costs ranging from 151.9p per litre to 152.9p.

These were closely followed by stations in Ballymena and Coleraine in Northern Ireland, and Hastings where figures currently show 152.9p per litre.

Sainsbury's offered the same prices in Ipswich and Dungannon, Northern Ireland, branches - while Esso matched these costs at a Liverpool forecourt.

Asda also provided diesel at 152.9p per litre at a station in Manchester.

On Tuesday, petrol across the UK averaged 154.5p a litre, having been at 157.1p on the first day of the month, according to the AA.

Meanwhile, diesel at 161.4p a litre by the end of the month was a decrease from 162.4p on October 1.

It comes as supermarkets and retailers have agreed   to back a fuel price   checker to drive down   prices for motorists.

Tesco, Asda, Sainsbury’s and Morrisons will share cost data with the public, Energy Secretary Grant Shapps revealed earlier this year.

Using PumpWatch, motorists will be able to find the best-priced petrol and diesel deals local to them.

The superstores, along with BP, Shell and Esso, agreed to implement the Competition and Markets Authority (CMA) watchdog’s voluntary information sharing scheme.

It comes after data, sourced through The Competition and Markets Authority (CMA), showed petrol stations can vary from 50p a litre across Britain, and diesel ranges by 45p.

As it stands, nearly 4,000 forecourts have signed up to the programme and uploaded their current fuel costs, as reported by .

RAC fuel price spokesman Simon Williams said: "Every day the supermarkets put off reducing their prices to fairer levels that reflect the lower wholesale market, is another day of extra profits for them, and another day of drivers having to fork out more money than they should have to for their fuel. 

"This is all made worse by the fact that fuel duty is currently being discounted by 5p a litre to ease the burden on drivers in the cost-of-living crisis – a duty cut that drivers simply aren’t benefiting from.  

"We highlighted these issues to the CMA, the Treasury and the Department for Energy Security and Net Zero last week, so were pleased to see that Energy Secretary Claire Coutinho has written to retailers making it clear they must pass on savings to drivers otherwise she will name and shame them."
