  • We’ll match 100% of the electricity you use with renewable sources, such as UK wind and solar – helping to reduce your home’s carbon footprint
  • 100% of your CO2 footprint from your gas use will be balanced by carbon-cutting projects around the world (90%), and renewable biogas made from food and farm waste (10%)
  • You’ll also protect five trees in the UK per fuel for each year of your green energy tariff, contributing to cleaner air and improving natural habitats

Our Green Futures tariff has won gold

British Gas is committed to improving the environment for everybody. So we’re delighted that our Green Futures tariff has been awarded the gold standard by Uswitch - one of only three energy suppliers to achieve this accreditation.

Winning gold takes effort and dedication. And to achieve the Uswitch standard, British Gas matches 100% of the electricity you use with renewable sources, such as UK wind and solar power. On top of that, the carbon footprint for 100% of the gas you use is balanced by CO2-cutting projects around the world. We also use renewable biogas from food and farm waste.

With Green Futures, you can be sure you’ve chosen one of the most environment-friendly tariffs available anywhere. Because we work harder to do our bit for the planet, we make it easier for you to do yours.

Frequently asked questions

What makes this tariff green?

Some tariffs offer additional benefits to the environment on top of any legal obligations the energy supplier may have, this is called 'additionality’. Our Green Future tariffs provide additionality. That’s because the 100% renewable electricity and 10% green gas that is matched to your use is over and above our existing environmental commitments. We also offset the carbon footprint created from 90% of the gas that you use on this tariff by supporting emission reduction projects in developing countries. Furthermore, we support UK tree-growing projects, this is in addition to offsetting the carbon footprint created by 90% of the gas you use on this tariff.

What if I change my mind?

Should you decide it’s not the right tariff for you and you want to cancel your contract, you won’t have to pay an exit fee within 14 days of signing up.

An exit fee may apply if you decide to switch to another supplier before the end date of your fixed tariff, but not during the switching window, which starts 49 days before the tariff ends. If you decide to change to one of our other tariffs at any time, there are no exit fees. Please see terms & conditions for full details including exit fees for each tariff.
