Green Tariffs

Importance of renewables and UK Government commitment to them

The UK Government remains committed to developing renewable technologies and growing renewable energy generation.

Suppliers already source 29% of their electricity from renewable sources. We already source 43% of our electricity from renewable sources. To view the British Gas Fuel Mix, have a look at our fuel mix table below.

How the electricity gets from being generated to your door

Electricity is generated from a variety of types of generation (e.g. coal, gas fired, wind) and is fed into the National Grid, and then through the transmission and distribution network to your home. At this point it all gets mixed up, regardless of the original source, so it is impossible to trace electricity generated from a particular renewable source through to an end customer.

So that means for green tariffs, suppliers will own or purchase certificates to show that for the equivalent amount of electricity used,the same amount has been fed back into the Grid.

Additionality

When green tariffs offer additional benefits to the environment, in addition to other legal obligations and schemes,this is called ‘additionality’. This could be matched renewable electricity that isn’t being counted against other obligations, or donations to an environmental organisation.

Our green tariffs for household customers

Our green tariffs match 100% of the electricity you purchase on the green tariff with renewable electricity. We also offset the carbon footprint of the gas that you buy from us. This means that for the electricity you use the same amount of green electricity will be fed into the network, and for the gas that you use with us the carbon footprint will be offset through carbon emission reduction projects in the developing world.

For our gas customers,for the green tariffs we sold in 2018 and started to sell before April 2019, we agreed to double offset your carbon footprint created by the gas used on your green tariff, by supporting carbon emission reduction projects in the developing world. You can look at your tariff terms and conditions if you want to check what makes your specific tariff green.

These tariffs provide an ‘additional’ environmental benefit. The renewable electricity that is matched to the electricity you purchase is in addition to our existing environmental commitments. We offset the gas carbon footprint created from the gas you purchase on our green tariff when we purchase Certified Emissions Reduction Certificates (CERs).

Our fuel mix

All suppliers, including British Gas, are required to provide information about the mix of fuels used to generate the electricity supplied to their customers as well as the environmental impact.

Known as the Fuel Mix Disclosure, we must publish this information annually. The table below shows the British Gas Fuel Mix Disclosure for the period 1st April 2018 to 31st March 2019.
