E10 Fuel Grade Rollout

From 1st September 2021, E10 petrol will be introduced as the UK-wide standard petrol grade at pumps. It is important that all fuel retailers are prepared for this change, have briefed their staff and communicated the change to their customers to avoid confusion.

The Department for Transport (DfT) have produced a wide range of communications assets here to help forecourt retailers communicate the changes to their customers using the “Know Your Fuel” campaign.

From 1st September 2021, there will be a 2-month period before the fuel sold at filling stations will be required to meet the 5.5% (ethanol content) minimum requirement to allow time for fuel deliveries around the UK.

These changes apply to fuel retailers that sell more than 1 million litres of fuel (both petrol and diesel) a year unless a specific exemption applies (detailed further below).

E10 petrol is any fuel grade up to 10 per cent ethanol, meaning anything over E5 grade is deemed to be E10. This will help to reduce carbon dioxide emissions associated with petrol vehicles in efforts to tackle climate change.

For vehicles that are not compatible with E10, the E5 ‘super’ grade fuel remains an option at all forecourts.

Around 95% of vehicles are compatible with E10 petrol but motorists can check their vehicles compatibility here.


E10 will become the standard petrol grade in Great Britain, meaning E10 petrol will be available at almost all petrol stations across England, Scotland and Wales.

Petrol stations that offer 2 grades of petrol will stock E10 (95 octane) and E5 (97+ octane) petrol. E5 (97+ octane petrol with no more than 5% renewable ethanol), however, will remain available at filling stations that sell 2 grades of petrol.

Some rural, remote or very small filling stations may sell only either E5 or E10 petrol as standard.

The Department for Transport has developed several assets including flyers for motorists, pump labels and compatibility charts available here for fuel retailers.


Fuel retailers must ensure that pumps are correctly labelled with the circular ‘E10’ or ‘E5’ label; visible on both the petrol dispenser and nozzle. (See correct labelling below)


The changes from 1st September apply to fuel retailers that sell more than 1 million litres of fuel (both petrol and diesel) a year unless a specific exemption applies (detailed further below).

However, exemptions can be granted to;

  • Any fuel terminal that is unable to blend ethanol into petrol will be able to apply for an exemption to the 5.5% minimum blend level.
  • Filling stations that are eligible for the Rural Fuel Duty Relief Scheme will not be required to meet the 5.5% ethanol requirement.

Fuel terminal exemptions will apply initially for 2 years.
