Warning on gas prices as cold snap hits supplies

Energy prices are at risk of rising after British Gas owner-Centrica warned about "concerningly low" storage levels due to the colder weather.

Centrica, which owns the country's largest gas storage facility, said the UK "has less than a week of gas demand in store".

There is no danger of the country running out of gas but it means the UK will need to buy more supplies from Continental Europe, the BBC understands.

Wholesale gas prices were lower in the UK on Friday.
