Fixed Term Energy Plan

Business energy plans are a bit like mortgages. Although market prices go up and down, we put together price plans that allow you to fix a certain rate for a certain amount of time. In general, the longer you fix, the higher the price.  But this lets you budget so you know what your prices are for however long you agree the plan.

But there are other things you should be aware of too, like what the basic standing charge is (no matter how much energy you use), what happens when your contract ends, and what to do if you want to end it early.

Variable Price Plan

Our Variable Price Plan currently takes effect once your Fixed Term Energy Plan ends and if you haven’t agreed another plan with us. With our Variable Price Plan you're not tied in and your prices won’t be fixed, but we'll let you know at least 30 days before they change. You can go back onto a Fixed Term Energy Plan at any time and if you decide to switch supplier, you just need to give us 30 days' written notice and pay any outstanding bills.

Out of Contract

Our Out of Contract rates now apply only in exceptional circumstances. If you choose to not agree a new Fixed Term Energy Plan with us when your current plan expires, you’ll now automatically move to our Variable Price Plan instead of our Out of Contract rates. Our Out of Contract rates are usually more expensive than our Fixed Term Energy Plan or our Variable Price Plan so we’ll notify you of the reasons we have moved you to these rates and provide you with suitable options. 

Out of Contract/ Variable Price Product rates for large and corporate customers

If your gas and electricity accounts are governed by our Terms and Conditions for Large and Corporate customers (v.9), then when variable price product rates apply you’ll be charged our out of contract rates published on this page.

Our Deemed rates apply when you become responsible for a property where we’re the existing supplier and you haven’t agreed a Fixed Term Energy Plan with us.

When this happens, you’ll automatically be placed on our Deemed rates. These rates are typically more expensive than our other rates and we’ll contact you with options to move to one of our other Price Plans or an alternative that is suitable for your business. If you are currently being charged Deemed rates, please contact us to discuss a suitable alternative.
