Tariffs with environmental benefits

The importance of renewables

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

Suppliers already source 33% of their electricity from renewable sources. But at British Gas, that figure goes up to 56%. Take a look at our fuel mix table for the period 1st April 2018 to 31st March 2019 below to see how we measure up.

How the electricity gets to your door

Electricity is generated in a variety of ways such as burning coal or using gas and wind turbines. It’s fed directly into the National Grid, and then through the transmission and distribution network to your home.

It isn’t possible to trace the electricity generated from a particular renewable source right through to each individual customer - it all gets mixed up in the grid. However, for some tariffs, suppliers will own or purchase certificates, such as Renewable Energy Guarantees of Origin (REGO) or Guarantees of Origin (GoO) certificates to show that the amount electricity used by customers on their tariffs has been sourced from renewable sources and fed into the National Grid.

Additionality

Some tariffs offer additional benefits to the environment on top of any legal obligations the energy supplier may have, this is called 'Additionality'. It could be matched renewable electricity or donations to an environmental organisation.

Tariffs with matched renewable electricity for household customers

Some of our electricity tariffs match 100% of the electricity you purchase on the tariff with renewable electricity. This means that for all the electricity you use, the same amount is fed into the National Grid from renewable sources. We evidence this by buying Guarantees of Origin (GoO) certificates or Renewable Energy Guarantee of Origin (REGO) certificates or both.

These tariffs provide an 'additional' environmental benefit because the matched renewable electricity is on top of our existing environmental commitments. Take a look at the terms and conditions for your tariff to see if it includes matching electricity from renewable sources.

Green tariffs for household customers

Our green tariffs match 100% of the electricity you use with electricity from renewable sources. If you’re a gas customer, we offset your carbon footprint by supporting carbon emission reduction projects in the developing world. We do this by purchasing Certified Emissions Reduction certificates or CERs.

If you signed up for one of our green tariffs in 2018 or a green tariff we started to sell before April 2019, we pledged to double offset the carbon footprint created by the gas you used. If you switched to a green tariff we started to sell after April 2019, we agreed to offset your entire carbon footprint for the gas you use.

Take a look at the terms and conditions for your tariff to see if it has green benefits.

 

Green Future tariffs for household customers

Our Green Future tariffs are the greenest home-energy tariffs we offer. We match 100% of the electricity you use and 10% of the gas you use on these tariffs with renewable sources. For 100% of the electricity you use, we’ll buy the same amount of electricity from renewable generators in the UK through agreements called Power Purchase Agreements. We evidence this by buying Renewable Energy Guarantee of Origin (REGO) certificates with the power we purchase from the renewable generators we have agreements with. For 10% of the gas you use, this means that the same amount of gas from renewable sources is fed into the gas network. We evidence this by buying Renewable Gas Guarantees of Origin (RGGO) certificates from the Green Gas Certification Scheme (GGCS).

With our carbon offsetting partner, ClimateCare, we also offset the carbon footprint from 90% of the gas you use by supporting traceable carbon emission reduction projects in the developing world. We do this by purchasing carbon credits, such as Verified Emissions Reduction certificates or VERs.  If you are on a Green Future tariff, we’ll also support emissions reduction projects in the UK, this is in addition to offsetting the carbon footprint created by 90% of the gas you use on this tariff. For example, if you switched to a Green Future tariff we started to sell after January 2019, we pledged to support growth of up to 5 trees per fuel in the UK per household.

Where your electricity comes from

All energy suppliers, including us, have to provide information about the mix of fuels they use to generate the electricity supplied to customers as well as their environmental impact. It’s known as the Fuel Mix Disclosure and we publish it every year. The table below shows the British Gas Fuel Mix Disclosure for the period 1st April 2018 to 31st March 2019.

Fuel Mix of our Products and Contracts

The table below shows the fuel mix if you are on a tariff with matched renewable electricity (including our green tariffs and Green Future tariffs). If you did not choose a tariff with matched renewable electricity, the fuel mix for all other British Gas products applies to your tariff. 

Our Renewable Electricity for Business customers receive their electricity from the National Grid. Which means we can’t track it directly from source to their business. But we do make sure that for every kilowatt hour they use, we feed the same amount into the National Grid from renewable sources.
