How Do You Know Which Supplier Is Best for You?
Not every business is the same. The best water supplier for a bakery might not work for a warehouse. Here’s what to think about:
| Feature | Why it Matters |
| Price per m³ | Lower usage = better for those with low daily needs |
| Billing Type | Monthly fixed or pay-as-you-go? Depends on your cash flow |
| Customer Support | Is there fast help when you need it? |
| Contract Terms | Can you leave early? Are prices locked in? |
| Extras | Do they offer leak alerts, audits, or usage dashboards? |
Is Switching Business Water Suppliers Easy?
Yes! Since deregulation, switching has become fast and easy.
Here’s how it works:
- Get your current usage and spend – look at your last water bill.
- Compare offers – sites like Utility Bidder or Direct Business Water can help.
- Choose your new supplier – check contract length and extra services.
- Let them handle the switch – most suppliers do all the paperwork.
Switching takes around 20 days, and there’s no interruption in service.
Can You Save Even More?
Yes! Try these smart tips:
- Install water-saving taps and toilets
- Fix leaks quickly
- Get a water audit – many suppliers offer them free
- Bundle with energy – some companies offer deals when you buy both
Businesses that monitor their usage closely save the most over time.
What If You’re in Scotland?
Scotland has had a deregulated water market since 2008, longer than England. Most of the same suppliers operate in both regions, but Scottish Water handles the main water system.
Castle Water, Wave, and Business Stream are top choices in Scotland for low prices and smooth switching.
