Fixed energy prices are available from many energy suppliers for up to 3 years. You do not have to wait until the last possible date to arrange renewals. Even if a renewal date is 4 to 6 months away, start to check the market for renewal deals. Also, it is essential to check the big and smaller suppliers: and, be prepared to go back to several suppliers a second time, you will get ‘revised’ rates.
This takes time, but will reduce costs. Consider using an independent energy advisor to undertake this work for your company, and you can still make the final choice of energy supplier(s) . These services are usually provided free, as it is standard industry practice for the selected energy supplier(s) to pay introductory commissions to the facilitator.
