Customer Service
Check what current customers are saying about the supplier. Look for reviews on platforms like Trustpilot to gauge customer service. Reliable customer support can significantly improve your overall experience.
Environmental Impact
Consider the supplier’s environmental policies. Does the supplier take measures to offset carbon emissions, such as planting forests or investing in renewable projects?
Business Gas Rates
Compare the rates offered by different suppliers. While price isn’t the only factor, finding a commercial gas supplier with competitive rates can significantly reduce your business’s operating costs.
Finding your business gas supplier
The easiest way to find your business gas supplier is to check your most recent business gas bill. Your supplier’s details will be listed there.
Alternatively, you can visit the Energy Network Association website to identify your gas network operator. Contact your gas network operator, and they can provide information about your current business gas supplier and the MPRN (Meter Point Reference Number) associated with your property.

Business gas suppliers – FAQs
Here, we answer your key questions about business gas suppliers, from finding a suitable provider to important considerations for your business.
What are business gas suppliers?
A business gas supplier is an Ofgem-licensed company that provides natural gas to non-domestic properties via the mains network. Here’s how they supply gas to commercial properties:
- Purchase: Suppliers buy natural gas on the wholesale market from:
- Natural gas extractors, primarily in the North Sea.
- European market importers via interconnectors (undersea pipelines).
- Importers from the Middle East or the US using liquefied natural gas (LNG).
- Distribution: The gas is transported to your business property through the distribution network.
- Metering: A business gas meter at your property measures the amount of gas your business uses.
- Billing: Your supplier bills you based on the rates agreed in your business gas tariff.
How do I make a complaint to my business gas supplier?
If you have a complaint, contact your supplier’s customer services department. Start by explaining the issue over the phone. Most business gas suppliers strive to offer the best service to customers.
If unresolved, formalise your complaint in writing. The Citizens Advice Bureau offers a template for complaint letters.
If, after eight weeks, your complaint is still unresolved, you can escalate it to the Energy Ombudsman:
- Website: Energy Ombudsman
How much can I save by switching business gas suppliers?
Savings depend on how competitive your current business gas tariff is.
If you’re on out-of-contract rates, switching could lead to significant savings.
Use our business gas comparison tool to compare prices and see how much your business can save today.
How long does it take to switch business gas suppliers?
Businesses usually arrange to switch suppliers months before their contract ends to ensure the switch happens on the day their current contract expires. If you’re on a deemed contract and need to switch ASAP, the process typically takes 17 to 21 days.
What should I do if I’m unhappy with my current gas supplier’s customer service?
Dissatisfaction with your current supplier’s service can be a valid reason to plan for contract termination. If you experience consistent issues or unresponsive support, our Business Energy Contract Termination Template can assist you in preparing to switch suppliers once your contract term ends.
