Business gas is one of the most negotiable overhead costs for UK businesses — yet most companies stay on rolled-over contracts without comparing alternatives. In 2026, the gap between the best and worst business gas deals can be thousands of pounds per year. This guide covers average rates, top suppliers, and how to find the cheapest deal for your specific usage.
Our Verdict
Small businesses pay approximately 7.2p/kWh for gas on a 2-year fixed contract in 2026. There is no single cheapest supplier — prices vary by usage, location, and contract length. Use an independent broker (Love Energy Savings, Utility Bidder, Bionic) to access the best bespoke rates and compare 10–150+ tariffs in 30 seconds. Always compare total annual cost — not just the unit rate.

How do I switch business gas suppliers in the UK?

Compare total annual costs — unit rate × usage + standing charge × 365. Switching takes approximately 6 weeks. You can switch 6–12 months before your contract ends without penalty.
Can I fix my business gas price in the UK?
Yes. Fixed-rate business gas contracts lock your unit rate for 1–5 years. This protects against price spikes. Given Cornwall Insights' prediction that gas prices will remain relatively flat for the next three years, fixed contracts offer budget certainty rather than necessarily lower prices.

What is the Climate Change Levy on business gas UK?
The Climate Change Levy (CCL) is a government environmental tax charged on business energy use. For gas, the CCL rate is 0.672p/kWh for 2025/26. It is added to your bill separately. Some businesses qualify for the 5% VAT rate (instead of 20%) if they use at least 60% of gas domestically or consume less than 145 kWh/day.
