Fuel labels are set to change across the UK this September

Find out what you need to know


The Department for Transport has introduced regulations that legally require new labelling on all fuel dispensers and nozzles across all UK filling stations by 1 September 2019. This applies to petrol, diesel and alternative fuels.

But don’t panic – there’s no need to worry or to change what you do. The fuel you use will remain exactly the same.

Here’s what’s the changes will mean 

The new labels will feature a circular symbol stating either E5 for petrol, or a square symbol saying B7 for diesel.

The E stands for ethanol, and E5 means the fuel contains up to 5% renewable ethanol.
The B stands for biodiesel, and B7 means the fuel contains up to 7% renewable biodiesel.
The fuels are exactly the same as before and are likely to still have labels saying petrol (or unleaded) and diesel.

Answers to possible additional questions


Why have new labels been introduced?

To help you choose the right fuel for your vehicle. The labels also tell you the maximum percentage of the relevant renewable fuel the petrol or diesel contains.

Have the petrol and diesel fuels changed?

No, they’re exactly the same as before.

What is E5 petrol and B7 diesel?

They are the same unleaded petrol and diesel you currently use. Petrol in the UK already contains up to 5% renewable ethanol, and diesel contains up to 7% biodiesel. This reduces overall carbon dioxide (CO2) emissions and helps the UK meet climate change targets. They’ve been blended into UK fuel for over 10 years.

Where will I see the labels?

At all filling stations – on fuel dispensers and nozzles, and on new vehicles.

My car or motorbike has a label saying it can use E10 petrol –what’s that?

E10 is petrol with up to 10% renewable ethanol. It’s yet to be introduced in the UK but could be in the future. E10 is already widely available in Europe and all vehicles with an E10 label can also use E5 petrol.
