Mike Smith

I have been a client for about 7 years.  I run a large, multi-site care business in the South East and was initially canvassed and offered some good rates, which I took up. They now look after every single energy contract I have.

I have had very little reason to contact D-ENERGi but on the occasions I have, found them friendly and helpful J.Hall.



Superb professional service! Would highly recommend D-ENERGi - we were already a customer from a previous contract and the rates offered were competitive and the service provided with excellent Zoe!
