The three broken Paywise meters are at Collings Road Shopper, Candie Cache, and Jeffreys Garage.
Customers can still top up at the Landes du Marche garage, Iceland at the Bridge and the Co-ops at the Market Building and the Forest.
Guernsey Electricity said it would “like to apologise for the inconvenience this may cause. If you have any concerns please give us a call on 01481 200700.”
The utility also confirmed it is in the process of purchasing new equipment which it says will take a few weeks to procure and install meaning the alternative locations for pre-pay customers should continue to be used until the new Paywise meters have been confirmed as in action.
