By completing this form and confirming you are entering into a legally binding contract to fix your prices for the chosen period, subject to our Terms and Conditions. These can be found online at: britishgas.co.uk/business/terms. You won't be able to end the energy plan until the full fixed price period has ended, nor will you be able to transfer to another supplier, unless our Terms and Conditions say otherwise. Please remember, after the end of the fixed period if you have any outstanding bills we may stop you from transferring to a new energy plan or another supplier until you have paid all the money you owe. We'll send you details of your options, prices and Terms and Conditions around 60 days before the end of this Fixed Price Energy Plan. If you do nothing at the end of your Fixed Price Energy Plan, you'll move onto our Variable Price Plan.
