Do you want to switch to a new supplier in London?

Switching suppliers isn't just for when you move house. But it's also for people who simply haven't switched in a while. If this applies to you, you are probably being overcharged for your gas and electricity supply. 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. This is because your energy bill tends to rack up the longer you have been on the same plan. It might seem like a super daunting idea to switch suppliers, but it really isn't! In fact, your energy supply isn't affected at all by switching, and our experts can carry out the whole process for you, from start to finish. You don't need to worry about a thing.

You will need to let our Switch Plan experts know your requirements so they can carry out an informed switch and get your new home in Greater London powered up.

So, you've just moved to Greater London? Did you know that moving house is the perfect time to switch energy suppliers? This is because when you move to a new property, you will inevitably have different energy requirements.

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. Our experts at Switch Plan can do all the comparison and heavy lifting for you.

And given that our experts will do it all for you, switching has really never been easier.
