Energy suppliers

If you’re paying too much for your gas and electricity, one of the easiest ways to cut costs is to switch energy suppliers. But with so many energy suppliers operating in the UK, it can be confusing knowing which company to go with. That’s where we help. Simply enter your postcode to start comparing energy deals from the all the suppliers in your area.

What is an energy supplier?

An energy supplier is a company that sells electricity and gas to households, businesses or both. In most cases, the energy supplier doesn’t actually create the energy they are supplying to you themselves, nor do they own the cables and distribution networks that allow the energy to be delivered to your home. But your energy supplier is the one who sends you your energy bills, and the one that takes your money. So, if you’re looking to save money at every opportunity, choosing the right energy supplier is vital.

Why switch energy suppliers?

The main reason that a record number of people are switching their energy supplier these days is to save money. Once your contract ends with any particular supplier, they will continue to supply energy to your home, but you’ll likely be paying a lot more than you need to for it. This is because suppliers invariably roll their customers onto their most expensive tariffs once their initial contract has ended – which usually lasts 12 months.

So, if you’ve not switched your energy supplier for a few years, or even if you’ve never switched at all, the chances are that you could be saving hundreds of pounds a year by finding a cheaper energy deal. Compare energy suppliers now to see how much you could save.

What to consider when comparing energy suppliers

As is the case when choosing any type of product or service, there are a variety of factors to think about before coming to the right decision. When it comes to comparing energy deals, you should consider the following:

  • Who is the supplier? Most people in the UK go with an energy supplier that they have heard of. In fact, around 70% of the country are supplied by one of the ‘Big Six’ energy suppliers – British Gas, EDF Energy, E.ON, Npower, Scottish Power or SSE. But just because they are well known doesn’t mean they’re the best. The suppliers that consistently rank highest in customer satisfaction tables are often smaller, independent suppliers. It is worth looking at every energy supplier closely, whether you know about them or not.
  • How is it rated by customers? The level of customer service that you will receive varies hugely between energy suppliers. Some, like Octopus and Bulb, consistently get rave reviews from their loyal customers, while others get a lot of negative criticism. When looking for a new supplier, have a look at some of their reviews, before you sign up.
  • Does it supply green energy? With climate change and the environment becoming an increasingly global issue these days, everyone from corporations to individuals are looking for ways to cut their carbon footprint and help the planet. You can do your bit by switching to a green energy supplier – one that gets 100% of your energy from renewable sources. You can check each supplier’s energy fuel mix on their individual pages.
  • How much do their tariffs cost? The price you pay for your gas and electricity is understandably the most important factor in most people’s minds when it comes to comparing energy deals. The final product - the energy that powers your home - is no different depending on which supplier you go for, so why pay over the odds if you don’t need to?

Supplier fuel mixes

No matter which supplier you're signed up to, your power comes from the national grid. The grid works effectively like a big bucket that suppliers put electricity into that is generated from a variety of sources. The power in the grid is therefore made up of electricity from a mix of fuels, and each supplier has its own fuel mix which will be different from (but contributes to) the national average. Knowing different suppliers' fuel mix is useful is you're concerned about the environment, as it allows you to pick a supplier who generates their electricity wholly or mostly from renewable sources.
