In short – no. Green Gas is chemically identical to fossil fuel gas but produced from renewable sources, so no changes are required in your home making going greener hassle-free!
For our members on the Greenest tariff, we guarantee that for 10% of the gas used, an equal amount of green gas that's been generated from renewable sources gets put back into the grid. This gas is certified under the Renewable Energy Association's Green Gas Certification Scheme. As a result, this proactive approach supports the generation of green gas.
