Green power from trusted suppliers


Current energy prices
Energy prices are currently at record levels. For now, you'll be best off financially doing nothing and sticking with your current supplier. We continue to offer green tariffs where available but note these will mean paying more. Get updated when the situation changes.

Every switch helps

A typical home could save hundreds by switching to a green energy provider. Get an extra £35 of free energy when you switch to a participating supplier through this page. A little extra help, from Tesco.

Tesco and WWF

Tesco and WWF have joined forces in the fight for our world. In our new four-year partnership, we’ve come together to address the most significant environmental and social challenges facing our shoppers, colleagues, suppliers, and communities. We will be working together to deliver existing sustainability commitments made in the Little Helps Plan.

What is clean energy?

‘Clean energy’ means power generated from the elements – sun, wind, water (rivers, tides or wave power) and biofuels (gas released by rotting food and agricultural waste). Unlike dirty electricity generated by burning fossil fuels (oil, coal and gas), clean energy has little impact in terms of climate change and air pollution.

How do clean tariffs work?

Picture the National Grid like a bucket full of water.* When you’re on a renewable tariff, your supplier promises to match the amount you take out of the bucket by putting the same amount of clean water in. The more clean water that goes into the bucket (and the less dirty water), the cleaner the bucket, and therefore the Grid, gets.

* In reality of course, water and electricity shouldn’t mix!
