Annual Price Plan review

To make sure you're on the most cost effective price plan, we check your energy usage every 12 months (as long as you're not on a fixed term plan). If we've got a better price plan for your needs, we'll automatically change it for you. It's all part of our commitment to great service. 

Think your usage might increase or decrease due to a change of appliances, or a change in who's living at home? Get in touch and we can talk to you about pricing and plan options.
