Question to the Department for Business, Energy and Industrial Strategy:

To ask Her Majesty’s Government what information they have about retail petrol and diesel price differences across the UK.

Her Majesty’s Government believes that a competitive market is the best way to keep prices low. Retail fuels markets are subject to UK competition law under the Competition and Markets Authority (CMA).

The Department for Business, Energy and Industrial Strategy does not collect statistics by the nations or the regions of the UK but it does publish weekly UK statistics retail petrol and diesel prices: https://www.gov.uk/government/statistical-data-sets/oil-and-petroleum-products-weekly-statistics. On 9 January 2017 the average retail price for petrol and diesel was 118.0 pence per litre and 121.3 pence per litre respectively.

The AA publishes data on regional retail petrol and diesel price differences across the UK: http://www.theaa.com/driving-advice/driving-costs/fuel-prices.
