Everything your business needs to know about switching water retailer in Scotland

- Compare licensed retailers below and switch with no disruption to your supply.
How the Open Water Market Works in Scotland
Since 2008, Scotland’s open water market has allowed businesses to choose their own water retailer. While the physical infrastructure stays the same, you can switch the company that manages and bills your account.
Scottish Water remains the national wholesaler, owning the reservoirs, treating the water, and maintaining the pipe network. This means your water supply, pressure, quality, and emergency services never change when you switch.
Your retailer handles billing, meter readings, and customer service. As this is the competitive part of the market, switching retailers can help you secure lower rates and better contract terms and Tariff.com makes the process simple.

The team at Tariff has provided Trans4orm Fitness with a fantastic service from start to finish. Following their expert advice, we opted to procure our energy long-term to protect the business from increases in prices, and as such we saved over £16,000 a year! We’re now using 100% Green Electricity too, which is important to be sustainable for our customers.
Our Account Manager Rachael has provided Elite Group with a fantastic service from start to finish. She audited and reviewed our Energy for multiple sites, aligned all of our contracts to one supplier and one end date. Rachael also forward procured our energy before the price increases, and has saved us thousands a year by doing this. I would highly recommend working with them and see how they can help your organisation!
The service we received from the Tariff team was second to none. They understood the requirements of the organisation and offered a professional service.

I rarely give public testimonials, but I’d like to recommend Tariff.com as an outstanding energy consultation service. Aside from recommending Tariff.com as a company, because personal recommendations based on experiences and feedback are the strongest of all, the benefits of using Tariff.com are factual and more welcome.
Frequently Asked Questions
Yes. All non-household properties in Scotland, including small retail shops, charities, public sector buildings, and massive multi-site corporations, can legally choose and switch their water retailer.
Absolutely not. The switch is entirely administrative. Since Scottish Water still manages the physical pipes, your physical water supply, flow rate, and pressure will not experience even a split-second of disruption.
Two main differences:
- Launch Date: Scotland’s market opened in 2008, whereas England’s open market was launched nine years later, in 2017.
- Wholesaler Structure: Scotland has a single, national wholesaler (Scottish Water). England, by contrast, relies on several regional, privately owned wholesalers.
Your physical wholesaler will always be Scottish Water. They own and maintain the physical pipes, reservoirs, and water treatment facilities across the entire country.
If you have never actively switched, you are on what is known as a deemed contract with a default retailer. While these default tariffs are capped by the regulator, they are rarely the most competitive option. You are free to switch away from a deemed contract at any time without paying exit fees.
The economic regulator for Scotland’s water industry is the Water Industry Commission for Scotland (WICS). WICS sets the wholesale charges, ensures fair retail competition, and protects consumer rights.
