With numerous business gas suppliers available, selecting the right one can be challenging. Here are the top factors to consider when choosing a business gas supplier:
Customer Service
Check what current customers are saying about the supplier. Look for reviews on platforms like Trustpilot to see if customers are leaving positive comments or making complaints about their business energy supplier.
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 business gas prices offered by gas suppliers. While price isn’t the only factor, choosing a supplier with competitive rates can significantly reduce your costs.
How to find 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.

What are business gas suppliers?
A business gas supplier is an Ofgem-licensed company that provides a natural gas supply to non-domestic properties. Here’s how they supply gas to commercial properties:
Gas purchases
Business gas suppliers purchase natural gas from gas extractors in the North Sea, LNG importers, or from European markets via undersea pipelines.
Gas Distribution
Business gas suppliers arrange for gas transportation through the British gas distribution network, including using independent gas transporters where applicable.
Metering and Billing
Business gas suppliers use the gas meter at properties to measure gas consumption and then bill customers according to their business energy contract.
