An energy expert has issued a stark warning to UK households: unplug your chargers and devices, or face an extra £75 on your annual electricity bill. Known as 'vampire power,' the electricity consumed by devices left plugged in but not in use is set to become more costly as the energy price cap rises by 13% on July 1, 2026.
Ofgem's Price Cap Increase
Ofgem, the energy regulator, has announced that typical annual dual-fuel bills on standard variable tariffs will increase to £1,862. This means the average cost per kilowatt hour (kWh) will rise to 25.11p. With many households leaving multiple devices plugged in, the wasted energy can quickly add up.
The Scale of Vampire Power
Research indicates that the average UK home contains up to 41 electrical devices, with 10 to 13 used daily. The rest remain plugged in, slowly draining power. According to SAGA, vampire appliances can consume up to 300 kWh per year, costing over £75 annually.
What Devices Are Guilty?
Common culprits include phone chargers, laptop chargers, and televisions. Glen Fariva, a Lecturer in Power Electronics at The University of Melbourne, explains: 'You might have a phone charger plugged in next to your bed without ever bothering to switch it off at the wall. The same might go for a laptop charger by your desk.' These devices draw standby power to keep control circuits running, which is lost as heat.
Safety Risks Beyond Cost
Fariva also warns of fire hazards: 'Chargers wear out over time, especially when exposed to voltage rises in the electricity grid. Cheap, uncertified chargers lack protection and can be a fire hazard.' He advises replacing any charger that feels warmer than usual, makes noise, or appears damaged.
Practical Advice
While some appliances like fridges and freezers must stay plugged in, most can be switched off at the wall when not in use. 'Although modern chargers are generally safe, consider unplugging them anyway if convenient,' Fariva adds.
With the July 1 deadline approaching, households have three weeks to take action. Unplugging unused devices can save money and reduce fire risk.
