Smart meters to cost the UK billions: 2G switch-off means replacing 12-13 million
The planned closure of 2G and 3G networks could leave 12 to 13 million UK smart meters unable to communicate properly by 2033, requiring a large-scale replacement programme. A report by connectivity company Wirepas estimates the work could cost about £4 billion, with the expense ultimately adding to household energy bills.
The affected meters include newer SMETS2 models, where the communications module can be replaced, and around 7 million older SMETS1 installations, which usually need a whole new meter. The report puts SMETS2 module replacement at £1.3 billion to £1.4 billion and SMETS1 replacements at £2.1 billion to £2.45 billion. UK mobile operators plan to begin switching off 2G from 2029 to 2030; 3G services have already been withdrawn.
In short
- Up to 13 million smart meters may need upgrades.
- The estimated replacement bill is about £4 billion.
- Older SMETS1 meters generally need full replacement.
