While most people will have heard of the 'Big Six' energy suppliers, you may come across some suppliers who you've never heard of. While comparing prices, you may see that these 'unknown' suppliers are offering better deals, but you may be concerned about the legitimacy of the supplier. Every energy supplier we compare is Ofgem-accredited, so you don't have to worry about any scams or rogue companies. If you're unsure, do some research on the new supplier, such as looking at any online reviews from other customers.
