Thames Water customers are being switched to monthly billing, and if they do not wish to accept this change, they must take proactive steps. This change affects 3.9 million households in London and the Thames Valley area, who generally received bills every six months.
Financial Background
Thames Water has implemented this plan due to its heavy debt burden. A six-month trial with 5,000 customers concluded last November, and now this plan has been expanded to approximately 110,000 to 120,000 additional customers.
Nearly 1.2 million Thames Water customers have smart meters that record their water usage hourly and send it electronically to the company. In contrast, regular meters require manual readings or bills are issued based on estimates.
Communication Discrepancies
Adrian Michaels, a media entrepreneur, only realized his billing method had changed when he noticed an additional charge in the month following his previous six-month bill payment. He stated: 'In July, I paid my six-month bill of £323, and in August, I received a monthly bill of £67.'
After three lengthy calls with customer service, he learned that he should have received proper notification about this change and had the right to opt out of this method. Thames Water initially informed him that a request to switch to monthly payments had been submitted by him, but he had not sent any email regarding this.
Thames Water's Response and Customer Monitoring
Thames Water confirmed that customers can opt out of this plan at any time or revert to the six-month billing. During last year's trial period, 11 percent of customers opted out of this plan. The company stated that the aim of this plan is not to improve cash flow and emphasized that effective communication with customers regarding changes is essential.
A spokesperson for the Consumer Council for Water (CCW) also highlighted the importance of effective communication about billing changes, stating: 'Transitioning customers to monthly bills and providing an option to return to six-month bills is one thing; however, transitioning them without prior notice is unacceptable.'
