Frequently Asked Questions
Is my business exposed to more risk through Flex Advantage?
Yes. Due to daily fluctuations in the energy market, we can't guarantee the lowest prices. However, Flex Advantage offers options to help you plan and mitigate your exposure to wholesale energy market risks.
Can I set up multiple users on the online platform?
Our online self-serve portal allows you to add multiple authorised users. You can view your portfolio demand forecast, check market prices, and complete all purchases in one place.
What are the benefits of flexible energy contracts?
Flexible energy contracts let you take advantage of market price changes, helping you manage costs more effectively. They also give you greater control over when and how you buy energy.
How is Flex Advantage different from fixed energy contracts?
Flex Advantage allows you to purchase energy in blocks at different times, so you can respond to market movements. Fixed contracts lock in a single price for the entire term, limiting flexibility.
Can I switch to Flex Advantage if I’m already with another supplier?
Yes, switching is simple and we’ll guide you through every step. Once you join, you’ll have access to our expert team and tools to manage your energy purchasing.

We offer Zero Carbon Electricity for Business Fixed Price Plans. Backed by Renewable Energy Guarantees of Origin and nuclear declarations. Helping to deliver on the UK's climate commitment and supporting our aim to help our customers achieve Net Zero by 2050.
100% Renewable Electricity: Every unit of electricity British Gas supply to you during your contract will be matched to electricity from a natural renewable energy source and we will hold the necessary number of Renewable Energy Guarantees of Origin (REGOs) as evidence of this supply. British Gas will use reasonable endeavours to purchase enough REGOs to match 100% of the electricity you use on this tariff. However, failure to do so will not constitute a breach of contract by British Gas or give rise to you having the right to terminate the supply contract. In the event something changes, and British Gas can no longer guarantee a renewable supply we will write and let you know. Excludes the British Gas Lite product.
