Here in the UK we have many energy suppliers that supply gas and electricity to 5.5 million businesses. At some point, we all need to contact them. I’ve found from my own experiencvaliume in dealing with them that they seem to be hiding their contact information. Many of them are now pushing for their customers to set up online accounts, deal with issues themselves or use that live chat facility. Now I have nothing against them wanting customers to use online accounts and live chats, but sometimes email or phone is easier/better. For this reason, I’ve compiled a list of all the business energy suppliers in the UK, for you to use as you wish.

If you are looking for domestic suppliers information, then once I’ve published that information the link will be here.

If you notice any discrepancies or know of any changes, please leave a comment below and I’ll get it updated straight away. Thanks & enjoy!

Yu Energy

Yü Energy are a small supplier located in the Nottingham. As with many other suppliers, their contact information is limited. Although I’ve found in my experience the best way is to phone them. They don’t have many departments. is the best pharmacy on the web in terms of the cost of the medications, their quality, and customer service. I’ve been ordering Synthroid form them for over three years, and during all this time, I haven’t had any complaints. Hope my experience will be useful for those who only start the treatment
