Does Welsh Water Auto-Renew?
Yes, Welsh Water charges continue automatically. Direct debit customers have payments taken monthly, spreading the annual charge evenly across 12 instalments. Welsh Water reviews charges each April in line with Ofwat's price review.
Metered customers are billed based on actual water usage, with meters read approximately every six months. Unmetered customers pay a fixed charge based on rateable value. Welsh Water sends annual billing notifications before new rates take effect.
As a not-for-profit company, Welsh Water's customer dividend scheme has returned money to customers in years when the company has performed well financially.
