Tesco’s chief executive has revealed that customers using its Clubcard Fuel Save promotion are saving an average of 7ppl on fuel, just three months after its national roll-out.

Philip Clarke was speaking after the company published another set of poor results and insisted the Fuel Save promotion was a key element in its strategy to turnaround its performance.

In its first quarter interim management statement covering the 91 days to May 24 it reported that like-for-like sales excluding petrol fell by 3.7% compared with the same period in 2013. When fuel sales were included like-for-like sales were marginally worse at -3.8%.

Clarke said the Clubcard Fuel Save promotion, which allow customers to accumulate discounts on their fuel based on their monthly spend in store and online, had a vital role to play in generating customer loyalty.

He said: “Clubcard Fuel Save will be a key point of difference in building long-term customer loyalty. Less than three months since launch it has already helped well over five million customers save an average of seven pence per litre. The scheme is driving clear changes in behaviour with a marked increase in fuel volumes towards the end of the month as customers seek to maximise the amount they can save.”
