We don't want to see anyone overcharged for their energy, so that's why our experts at Switch Plan are professionals in making sure you make savings.

So, whether you have lived in Greater London for a long time, or have recently moved there and want to switch, you have a wide range of options. In Greater London, there are a number of suppliers available for you, no matter your energy requirements. From green suppliers to the cheapest on the market, there is something for you. What we know for sure is that switching energy suppliers is a foolproof way to make hefty savings. That's what our experts are here for.

What does it mean to switch energy supplier?

In short, it means that you can save up to ยฃ400 a year. Sticking with the same supplier isn't great for making savings.

Therefore, switching energy suppliers is often a very necessary part in the moving house process. Luckily for you, residents of Greater London have a huge range of options when it comes to plans and suppliers. Don't be overwhelmed though.
