All pumps are required to meet legal accuracy standards of between -0.5% and +1%.  All pumps should be sealed to ensure they cannot be tampered with. Every time the pump is repair the same checks are carried out. In addition your Local Trading Standards may undertake random checks on the pumps to ensure they are accurate.

If you believe the pumps are inaccurate you should use resolver to report this issue to your local Trading Standards department at your local council. They will then be able to investigate the issue.


  • Always check the displays return to zero before starting your delivery
  • If the display advances before you have delivered any fuel replace the nozzle and let the kiosk staff know.
  • Make sure you are buying the grade of fuel you want. All garages advertise the price of ordinary unleaded fuel on the road side sign. Many also sell a higher grade of petrol, but this is more expensive. Check the unit price displayed on the pump is what you want to buy. The same is true for different grades of diesel.
  • Note the price to pay when you have replaced the nozzle. This should be the same price as displayed in the kiosk. Sometimes the pump display will jump a penny between finishing delivery and replacing the nozzle. This can happen for a number of reasons and gets more likely as the price of fuel increases.
You should know
  • Petrol pumps are checked for accuracy when they are installed and serviced
  • Trading Standards will also check the accuracy of pumps. If you experience issues, you should report the issue to your local Trading Standards. You can do this via resolver
  • All pricing should be clearly displayed to you before your purchase 
  • If you experience any problems, raise them while you are still at the petrol station and take down the name of the person that you spoke with. If your problem is not resolved at the station, you can raise a complaint via resolver
