How to choose the best business gas supplier
When choosing the best business gas supplier, it’s important to consider t more than just the unit rate. The right supplier can make a big difference to your business, so consider these four key factors:
Overall cost
Check the unit rate per kWh and the standing charge, but also look at the full contract cost over the term. A slightly higher unit rate may still work out cheaper overall, depending on your usage.
Customer service
Good support is essential when billing issues or supply queries arise. Before choosing a gas supplier for your business, look at independent ratings on sites like Trustpilot to see how real customers rate their service.
Green gas options
Many business gas suppliers now offer renewable or carbon-offset gas. If your business has environmental goals, choosing a supplier with green gas tariffs can help demonstrate your commitment to reducing carbon emissions.
Small business gas suppliers
While major names like British Gas lead the commercial gas market, many smaller providers offer tailored services designed for small businesses.
Here are three small business gas suppliers that offer something a little different:
Ecotricity
Ecotricity provides carbon-neutral business gas through its Green Gas Mill in Berkshire, using grass cuttings to generate clean energy.
Regent Business Gas
Specialises solely in business gas, offering supply, metering, and connection services with a focus on expert support.

Business gas suppliers – FAQs
Our experts answer commonly asked questions about business gas suppliers.
What should I consider when choosing a business gas supplier?
With so many business gas suppliers to choose from, it’s important to focus on what matters most. Here are the key factors to help you find the best business gas supplier for your needs:
Customer service: Check reviews on platforms like Trustpilot to see how other businesses rate the supplier. Good service can make all the difference, especially for small businesses.
Environmental impact: If cutting emissions matters to your business, look for gas suppliers that offset emissions or invest in business green energy projects.
Business gas rates: The cheapest business gas supplier isn’t always the best, but competitive pricing is still essential. Review both unit pricing and business gas standing charges.
How can I find out who my business gas supplier is?
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?
Business gas suppliers are Ofgem-approved companies that provide natural gas to non-domestic properties. They purchase gas from wholesale markets, including LNG (liquefied natural gas) importers, and arrange delivery through the British gas distribution network.
In some cases, they may also work with independent gas transporters to reach more business locations.
A supplier measures your gas usage using a gas meter and bills you according to your business energy contract.
How do I make a complaint to my business gas supplier?
Start by contacting your supplier directly. Most have a clear complaints process on their website or through customer service.
If the issue is not resolved within eight weeks, you can contact the Energy Ombudsman for a free and independent review.
