Many companies treat water as a fixed cost. However, in today’s deregulated market, failing to review your supplier could mean missing out on savings and better service. This guide outlines seven key signs that your company should switch business water suppliers to secure cheaper rates and more efficient management tools.

1. You Haven’t Reviewed Your Tariff in Over 12 Months

Water markets change. Tariffs shift yearly based on infrastructure costs, wholesale prices, and operational trends. If you haven’t compared business water suppliers in over a year, you could be paying above-market rates. A quick tariff check could highlight savings of 5% or more.

2. Your Business Has Grown or Changed Location

A change in premises or expansion into multiple sites is a perfect moment to reassess your supplier. The best business water suppliers offer consolidated billing and flexible terms for companies with multiple meters or complex footprints.

3. You’re Receiving Estimated Bills

If your bill isn’t based on accurate meter readings, you’re likely overpaying. Modern providers offer AMR (Automatic Meter Reading) and real-time tracking to avoid billing errors. In 2024, most high-performing suppliers use digital dashboards.

4. You Can’t Access Your Usage Data Easily

Are you still waiting for paper invoices or manually updating spreadsheets? That’s outdated. Top-rated water retailers let you track usage via online portals. Some even integrate leak alerts or sustainability reports.

5. You’ve Had Poor Customer Service

Late responses, confusing invoices, and unresolved issues are all reasons to move. Suppliers like Wave Utilities or Everflow Water consistently rank well for customer support.

6. You’re Paying More Than Benchmark Prices

In 2024, average SME water costs are around £2.05 per m³. If your rate is above £2.20 and you haven’t negotiated recently, you’re likely overpaying. Comparing suppliers is the only way to find out.

7. You Want to Support Sustainability

Want to cut your carbon footprint? Some suppliers offer water-saving audits, reuse solutions, or help track your environmental goals. Companies like Business Stream and Castle Water support green business reporting.

Bonus Tip: Use Ofwat’s Tools

Platforms like Ofwat and CCWater offer impartial performance and complaint metrics for all licensed retailers.

How to Switch Business Water Suppliers

If you’ve spotted any of these signs:

• Review your current contract
• Gather quotes from 3–4 alternative retailers
• Compare billing tools and support ratings
• Authorise the switch (usually completed in 28 days)

There’s no service disruption during the process, and your water quality remains the same.

Additional Warning Signs You Might Be Overpaying

8. Your Water Use Is Seasonal and You’re on a Flat Rate

Many businesses, such as those in agriculture, retail, and hospitality, experience highly seasonal usage. If your supplier doesn’t adjust your billing profile to match this, you could be charged based on outdated assumptions. A seasonal review can bring substantial savings.

9. You Haven’t Conducted a Leak Detection Survey

Hidden leaks can cost thousands annually. Even slow leaks—especially from toilets or underground pipes—can inflate bills. Retailers like Wave or Business Stream offer site audits or remote detection tools. If your supplier hasn’t recommended one in years, it may be time to switch.

10. You Manage Multiple Premises Separately

Managing water bills for more than one location should not require juggling multiple contacts or invoices. Modern suppliers consolidate billing and offer a single portal login for your entire portfolio. This saves time, reduces error, and improves forecasting.
