It is estimated 1.5 million more children will be eligible to use eGates with their families, based on 2025 UK arrival figures. The move is expected to cut processing times significantly as previously these children would have had to see a Border Force officer.

Before the change, children aged 10 or over could used the eGates, meaning families with younger children had to wait longer to pass through passport control. Children must be at least 120cm / 3ft 11in tall to use Britain's eGates.

There are more than 290 eGates at UK airports and ports, plus juxtaposed ports (where UK border checks take place in Europe).

Alex Norris, Minister for Border Security and Asylum, said: “Today’s change will make journeys easier for families with small children and reduce the hassle of travelling home after a holiday.

"It will also free up more time for tourists to enjoy our fantastic country this summer and in the years ahead.”
