Business gas contracts in the UK are unregulated by the Ofgem domestic price cap and are agreed directly between supplier and customer. Rates vary by consumption, meter type, region and contract length. Typical SME gas unit rates in 2026 range from 5p to 12p per kWh. Brokers must disclose their commission under Ofgem rules in force from April 2025. Switching business gas supplier follows the same 17-business-day cooling-off process as electricity (Ofgem, 2026).
