What is clean electricity?

By ‘clean electricity’ we mean power generated from renewable sources – sun, wind, water (rivers, tides or wave power) and biofuels (such as gas released by rotting food waste). Unlike electricity generated by burning fossil fuels (oil, coal and gas), clean energy has little impact in terms of climate change and air pollution. No tariffs available through our site source electricity from nuclear power. Click here to find out more.

How do clean tariffs work?

Picture the National Grid like a bucket full of water.* When you’re on a clean electricity tariff, your supplier promises to match the amount you take out of the bucket by ensuring the same amount of clean water goes in. The more clean water that goes into the bucket (and the less dirty water), the cleaner the bucket (or the Grid) gets.
* In reality of course, water and electricity shouldn’t mix!

Need some #GMCleanspiration?

We love clean energy, and we love Greater Manchester, so we’ve brought the two together in a new series of case studies showcasing environmental innovation and leadership from across the region. We’ll be adding to these over the weeks ahead – if you’d like to suggest a project or business, get in touch.

More power from your switch

Whenever anyone switches energy company through a third party like the Big Clean Switch, the supplier pays a commission. This doesn’t affect the price of the tariffs we offer, which are the same price, or even lower, than they are on suppliers’ own websites.

Greater Manchester Combined Authority will use a small part of its share to help cover the costs of promoting the campaign in Greater Manchester, with the remainder going to local environmental projects, such as energy efficiency schemes to help lower carbon emissions and reduce bills.

A word about fixed and variable rate tariffs

There are two types of energy tariffs: ‘fixed’, where the price of a unit of energy won’t change for a set amount of time (usually a year); and ‘variable’, where the supplier can change the price of the energy they sell, providing they give you advanced warning. If you choose a fixed rate tariff, bear in mind that prices could go up at the end of the contract, so make sure you put a note in your diary to check prices again around that time. There’s more information about the differences between fixed and variable tariffs on our help page.
