The EG Group, which has 389 petrol stations, has tonight announced a £30 limit on fuel because of 'unprecedented customer demand'.
The rule will exclude emergency services filling up and lorry drivers but has been put in place to give everyone a "fair chance" at filling up their cars.

In a statement published by the company, a spokesperson said: “Due to the current unprecedented customer demand for fuel and associated supply challenges we have taken the decision to introduce a limit of £30 per customer on all of our grades of fuel.
"This excludes HGV drivers and emergency services due to their vital role at this time.
“This is a company decision to ensure all our customers have a fair chance to refuel and to enable our sites to carry on running smoothly.
"We kindly ask everyone visiting our sites to treat our colleagues, supply chain partners and customers with respect during these very challenging times.
"All of EG Group’s UK sites remain open and operational to serve customers.”
Across the UK there have been long queues outside petrol stations today (September 24), amid fears of a fuel crisis.
BP said that around 20 of its 1,200 petrol forecourts were closed due to a lack of available fuel, with between 50 and 100 sites affected by the loss of at least one grade of fuel.
A 'small number' of Tesco refilling stations have also been impacted, said Esso owner ExxonMobil, which runs the sites.
The Transport Secretary has urged drivers not to panic buy petrol.
Grant Shapps said on Friday that motorists should 'carry on as normal'.
He told Sky News: "The advice would be to carry on as normal, and that is what BP is saying as well."
