Britain has enough gas, the network operator has said after warnings that stores are at “concerningly low” levels. National Gas said on Friday that supplies remain “healthy” and that Britain is “well-placed” to respond to demands this winter. It added that gas stocks kept at the UK’s storage sites are well-above half full.

Britain's gas storage levels are worryingly low, with less than a week's worth of gas in storage after a cold snap, energy company Centrica said on Friday while the government said there was no need for concern.

Britain has always cared about the weather, but this week’s “dunkelflaute” – a spell of low temperatures and plummeting wind speeds – shows how vital it is to the economy as well as its conversations.
