    “I have been a member of the Bodyshop Fellowship from the beginning and whilst I have had a few jobs so far, I understand this is a longer term commitment. Andy & Mark put me onto CES for a review of my energy supplies. They have saved me at least £750 on my annual spend for gas and are currently negotiating our electricity supply which should from the quotes so far save a similar amount but of equal importance to me was the fact that there was no hard sell, they went at my pace, and delivered beyond my expectations.”

Working for a small business and wearing many hats it is very hard to spend the time searching the market place for the best deals that suits our needs and am confident CES do this for us every time.

  • Renew was set up 2 years ago and like all new business’s faced a testing time in its first 3 years.”By switching to C.E.S Energy Brokers we made a significant saving last year. Our staff numbers have since trebled and we have expanded the building so the ongoing savings are of great benefit. The whole service and process was painless.
