Despite the looming 2030 ban on new petrol and diesel vehicles, the UK is still heavily reliant on oil.

Some regions rely on oil much more than others but which is the most reliant, and will face more dramatic changes in the coming years as we head towards the switch to electric?

To uncover which UK regions are the most oil-reliant, Select Car Leasing analysed six motoring and energy-related factors including:

Number of EVs as a percentage of total vehicles

Number of plug-in hybrids as a percentage of total vehicles

Number of fossil fuel pumps as a total of all car fuel types (including EV chargers)

Number of EVs per charger

Number of ICE cars per pump at a fuel station

Number of renewable energy sites in each region as a percentage of the UK total

Northern Ireland is the most oil-reliant region in the UK

Northern Ireland’s low number of EVs (just 0.5% of total vehicles) lands and their unequal ratio of fuel pumps to electric chargers earns them the title as the most oil-reliant region in the UK.

In addition, Northern Ireland earned the poorest score in two different categories; the ratio of fossil fuel pumps to EV chargers and number of electric vehicles overall. Their scoring earned them a score of 48 out of a total 72.

According to Select Car Leasing’s findings, 93% of total fuel types in Northern Ireland are ICE fuel pumps, meaning just 7% are EV chargers – earning them a steep score of 12.

Northern Ireland did, however, receive the best score of all regions when looking at the ‘number of ICE cars per pump’ score.. Northern Ireland’s number of fuel pumps mean theres 270 ICE cars for every pump, a saving grace when comparing it to the South East’s 738.

Surprisingly, London is the least oil-reliant region

Receiving the best score against 4 categories in Select Car Leasing’s index, London is the UK region that is least reliant on oil. They had the highest number of EVS and hybrids as a % of total cars, plus the lowest number of EVs per charger. This combination of scores earned them a total of 27 out of 72.

However, it did receive the worst score (12) for having the fewest renewable energy sites for every 100,000 in their population, with just 2.9% of the UK’s total renewable energy sites residing in the region of London.
