Petrol stocks at UK filling stations, including Northern Ireland, declined after the Iran conflict began on February 28. Data from the Department for Energy & Net Zero covers snapshots from 4,900 stations across the UK.

In Northern Ireland, petrol levels reached a low of 26% on March 28. UK averages dropped from 44-47% in late February to 36-43% in early March, with a minimum of 36% on March 4, 6, and 7.

Diesel stocks in Northern Ireland hit 35% during the first four weeks of the conflict. UK diesel averages fell from 47-52% to 37% on March 6, then rose to 42% later.

Increased demand drove the drops. Petrol deliveries to stations averaged 7,333 litres per day from March 1, exceeding prior weeks' 7,071 litres, but sales hit 7,615 litres daily.

Diesel deliveries averaged 8,157 litres daily from March 1, up from 7,919 litres, while sales reached 8,458 litres. A Department of Energy spokesperson stated supplies continue normally with no reported issues.

UK petrol prices averaged 158.0p per litre on Thursday, up 25.2p since February 28. Diesel averaged 191.1p per litre, up 48.7p.
