Additional information
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.
