Wholesaler charges increase from 1 April 2025
Wholesalers are required to publish details where bill increases are greater than 5% from the previous year.
Several wholesalers have published these statements on their websites and there are significant wholesaler price increases for the 2025-26 charging year, ranging from 5% up to 46% in one wholesaler region.
The charges increase you will see reflected on your bill will vary depending on your wholesaler, whether you are metered or unmetered, the amount of water you use and your contracted terms. If you have multiple sites across different wholesaler regions, your charges will again vary across your bill.
For your ease, we have listed below the key figures, where published, and links for each wholesaler with more detailed information on their 2025-26 charges.
