Big 2G shutdown for the UK

Consumer Scotland has warned that the 2G switch-off could disrupt communications hubs in first-generation energy smart meters.

UK mobile networks plan to retire 2G services by 2033, and most have already switched off 3G.

Each network will make its own changes at different times, and some will retire or restrict 2G earlier than others.

The watchdog said the switch-off has particular implications for the communications hubs in older smart meters.

Many time-of-use and flexible energy tariffs depend on a smart meter working properly.

Customers whose meters stop running in smart mode could end up paying more than they expect, Consumer Scotland said.

The watchdog said energy regulator Ofgem, the Data Communications Company and energy suppliers know about the issue and should have plans to replace or upgrade the hubs.

It urged Ofgem and Ofcom to keep in close contact to protect energy customers before the switch-off.

Care alarms, security alarms and payment terminals that connect over 2G will also need checking for compatibility.

UK mobile networks and the UK Government agreed a 2G Switch-off Charter in early 2026 to protect critical national services and vulnerable customers.

The charter requires networks to confirm 4G or 5G coverage exists in an area before switching off 2G there.

It also places responsibility on 2G users to identify any impact on their services and act to stay connected.

Many consumers buy from resellers such as Tesco Mobile or Sky Mobile rather than directly from the networks running 2G.

Consumer Scotland said it is unrealistic to expect consumers to know about the changes.

It called on Ofcom to monitor public awareness of the switch-off and set a target level of awareness among affected consumers.

Awareness below that target should trigger a government-backed information campaign, similar to the one run for the landline switch to digital calling.
