According to latest government figures 23670 Croydon households pay for their electricity using prepayment metres, needing to go to the shops to top up their meters. The government has just issues the guidance below about supporting residents using prepayment meters who cannot leave their homes due to the coronavirus/COVID-19. This guidance is for both gas [card] meters and electricity [key] meters
The guidance asks residents to contact their energy suppliers, to discuss options for keeping them supplied. This could include nominating a third party for credit top ups, having a discretionary fund added to their credit, or being sent a pre-loaded top up card so that their supply is not interrupted.
