Due to rising costs, many providers have removed their deals from the market, so we're unable to switch you right now
Spiralling energy costs have forced many suppliers to remove their tariffs
What this means for you:
• We probably can’t save you any money right now because there aren't enough tariffs to compare
• We hope we can help you save in the future – but we don’t know when that’ll be
• If you go direct to energy suppliers’ websites you might find better deals
We believe in always doing the right thing for our customers – which is why we’d rather tell you now, so you don’t waste time quoting if we probably can’t help you.
A green energy tariff matches the energy you buy with renewable energy.
Some tariffs are 100% renewable, while others use a proportionate mix of renewable and non-renewable energy. You can also get nuclear-free or carbon-offsetting green tariffs.
Energy regulator Ofgem has worked to increase the transparency of green deals. That means it’s much easier to see whether suppliers’ tariffs are using 100% renewable energy or a mix – it’ll be clearly signposted with each tariff.
Your energy supplier should also tell you what sources are used to provide your energy, like wind, solar, coal or nuclear.
Green energy tariffs usually only apply to your electricity supply, but there are a few green gas deals, or dual fuel options, available too. You can’t easily source renewable gas, so with these tariffs, your carbon is offset instead.
Here are a few different ways green energy is generated:
Wind pushes around large blades to drive a wind turbine which converts the energy into electricity
Solar panels absorb sunlight and convert it into electricity
Large volumes of falling water drive a turbine which makes electricity
Captured from waves in the ocean, rivers, lakes, and canals instead of falling water
The tide rises and falls twice a day due to the moon’s gravitational pull. The energy this produces is turned into electricity
Biological materials, such as plant matter, can be used as a fuel source to power generators, producing electricity. Biofuels are also mixed into non-renewable gas supplies

Check which providers use green energy, and weigh up the price, supplier rating and early exit fees of each
Once you’ve found the right tariff, sign up and your new supplier will handle the switch
If you generate renewable energy yourself – for example, if you have solar panels on your roof that produce more energy than you can use – you can pick a tariff that lets you feed surplus energy back into the grid.
These ‘feed-in’ tariffs were part of a scheme which was closed to new applicants on 31 March 2019. It’s been replaced with a new scheme called the smart export guarantee (SEG).
Green options may prove a little more expensive than other tariffs, due to the investment the energy firms put into sustainable projects and renewable technology. But that’s not to say you’ll always pay more.
What you pay depends on your energy usage, and how competitive the deal you pick is. Some customers find themselves paying less - while helping the planet at the same time.
Due to an Ofgem investigation back in June 2014, it should be clearly stated whether a deal is green and whether it provides any environmental benefits. Energy providers also need to show that environmental benefits happen because consumers chose a tariff and not solely due to subsidies or supplier obligations.
Suppliers must be able to prove where your green electricity supply comes from by having the right amount of Renewable Energy Guarantees of Origin (REGO) certificates. REGO’s are a way for suppliers to prove that the energy they provide is renewable. Ofgem issue one REGO certificate per megawatt hour of energy produced by a renewable source.
