Mayer wants a return to how things were in World War Two and is hosting an adjournment debate, external in Parliament. These debates are a chance for MPs to raise an issue and get a response from a minister but do not include a vote afterwards.
Mayer has argued that a return to what is known as “Churchill Time” could help save a combined £485m in yearly electricity bills – and reduce carbon emissions by more than 400,000 tonnes.
She called this “a low-cost, high-impact proposal” to “help meet climate goals, reduce energy bills, and boost our High Streets by making better use of the daylight hours we already have”.
She is not the first MP to bring this discussion to Westminster.
In 2012, a bid by Conservative MP Rebecca Harris to move UK clocks forward by an hour for a three-year trial period failed after the legislation ran out of time in the House of Commons.
In 1968, there was a three-year experiment to keep BST in place throughout the year. On average, there was a huge reduction in road casualties, but this has since been attributed to new drink-driving legislation in 1967.
