Drivers are being warned of costs that could soar in the coming weeks and months as the price of fuel continues to skyrocket in response to the conflict in the Middle East.
The global price of oil remains above $110 (£82) as the United States and Israel continue strikes against Iran, prompting fears around the skyrocketing price of petrol and diesel.
The conflict in Iran will likely continue for the foreseeable future, especially as US President Donald Trump promises to escalate the conflict by sending more troops to the Middle East.
Given that Iran has closed access to the Strait of Hormuz, which carries around one-fifth of the world's supply of oil, prices have risen dramatically since the killing of Iran's Supreme Leader Ayatollah Ali Khamenei at the end of February.

Drivers could face huge costs at the next HMRC update to advisory fuel rates
| PA/GETTYHMRC releases new advisory fuel rates (AFRs) four times per year, with the most recent update coming at the start of March.
These rates are used to reimburse employees for business travel in their company cars, or if a business needs employees to repay the cost of fuel used for private travel.
Petrol and diesel rates are calculated using the latest fuel prices from the Department for Energy Security and Net Zero (DESNZ), and with costs soaring, the next update could see rates hiked.
GB News has rounded up the most recent update to the advisory fuel rates ahead of the next change, which is currently scheduled for June 1, 2026.
