Does Severn Trent Auto-Renew?
Yes, Severn Trent charges continue automatically. Direct debit payments are taken monthly, with the amount based on your annual bill divided into equal instalments. Severn Trent reviews charges each April in line with Ofwat's price review determinations.
Metered customers receive bills based on actual water consumption, with meters typically read every six months. Unmetered customers pay a fixed annual charge based on the rateable value of their property. Severn Trent sends billing notifications ahead of the April change each year.
You can submit your own meter readings online or through the Severn Trent app to ensure your bills reflect actual usage between official reads.
How to Cancel Severn Trent
You cannot cancel or switch your water supplier. Water supply in England and Wales is a regional monopoly — Severn Trent is the only provider for the Midlands and mid-Wales. You can take steps to lower your bill instead.
Options to lower your Severn Trent bill
- Request a water meter — free installation, usually saves money for smaller households
- WaterSure scheme — caps metered bills for qualifying low-income and vulnerable customers
- Big Difference Scheme — Severn Trent's social tariff for households earning under £16,105
- Here2Help — payment support for customers struggling with bills
