Your Water Rates and Chargers At Northumbrian Water
At Northumbrian Water, water chargers are split into two parts: sewerage services and water supply. Here are some things to consider when it comes to water rates in Northumbria.
Metered: Your water usage will be based on meter readings and how many cubic metres of water you use.
Unmetered: If your premises doesn’t have a water meter, you’ll pay unmetered charges based on rateable value.
Surface Water Drainage: You’ll need to pay for the rainwater that is drained from your premises. This may be included as part of your sewerage charge.
Why Businesses Are Switching Water Provider?
Rising fixed charges from Northumbrian Water are pushing up bills, even for low-usage businesses. With Ofwat approving up to a 21% increase in household rates by 2029/30, many expect similar rises for commercial customers.
The situation is further complicated by six major suppliers, including Northumbrian Water, appealing Ofwat’s pricing decisions, fuelling uncertainty across the sector. As costs climb and regulatory tensions grow, more businesses are switching to secure better rates and greater billing transparency.

Frequently Asked Questions

Wholesale and retail water rates reset every April. In recent examples for Northumbrian Water, prices rose by around 13.6–17% depending on usage volume. While wholesale sewerage billing will reduce to 95% of water volume from April 2025, the unit charge has increased to balance the change.
Tariff.com offers detailed water audits to uncover inefficiencies and compare quotes across multiple retailers. If switching is advantageous, we help you move seamlessly to the best tariff. We also help businesses assess metering opportunities, manage supplier relationships, and simplify billing across sites.
If your site has a water meter, charges are based on actual usage in cubic metres. Without a meter, charges are calculated using your property’s rateable value. Some businesses qualify for meter installation if that could reduce costs.
Once you decide to switch, Tariff.com manages the entire process, from contacting your new supplier to handling paperwork. We coordinate onboarding, agree on switch dates, and ensure billing continuity, all without disrupting your water service.
