Shops across Wales could face penalties of £1,500 for selling high-caffeine energy drinks to under-16s under proposals published by the Welsh Government.

A consultation launched on Thursday, 5 November, sets out how a proposed ban would be enforced, including age checks, online sales and action against retailers breaking the rules.

The restriction would cover drinks containing more than 150mg of caffeine per litre (mg/L), with tea and coffee excluded. For context; a standard 250ml can of Red Bull has 320mg/L, a 330ml can of Coca-Cola has 100mg/L.

Under the plans, individuals and businesses employing fewer than 50 people could face fixed monetary penalties of £1,500. Medium and large businesses could face £2,500 penalties, while criminal prosecutions could also result in fines of up to £2,500.

Local authority food enforcement teams, would be responsible for monitoring compliance.

The Welsh Government is also considering test purchasing to identify businesses selling the drinks to children.

Ministers intend to prohibit sales through automated vending machines and introduce age-verification requirements for online purchases.

The government says research has linked children's consumption of high-caffeine energy drinks with disturbed sleep, headaches, tiredness, anxiety and difficulties concentrating.

Although some retailers already operate voluntary age restrictions, ministers argue that legislation would establish consistent rules for supermarkets, convenience stores and other businesses.

An earlier consultation in 2022 received 331 responses, with 72 percent supporting restrictions in principle.

Deputy Minister for Public and Preventative Health Nerys Evans said the latest consultation would help determine how the restrictions should be introduced and enforced.

The proposals would not make existing sales illegal immediately, with legislation and implementation arrangements still to be finalised.

Retailers, parents and other residents are being invited to respond to the consultation before it closes on 17 December.

The Welsh Government says responses will help determine the final arrangements, including penalties, enforcement responsibilities and the timetable for introducing restrictions.
