This Company (Griddy) is a good example of Competition in the energy industry – we joined this Electricity company in June 2019 and have not looked back. It reduced our power bill by half in some cases more. Also found though, very quickly I might add, that we needed to keep an eye on the app to check on change of charges. They do notify you on your phone when charges become higher. The change of price can happen when the weather gets very hot in the summer usually in the afternoon.
This is a great feature especially of you have control of your air conditioning or power system from your phone. (you can alter your power at home from work). Even better if you work from home, you are able to turn off appliances that will be sucking up power when the charges are high. Especially your air-conditioning .
Anyway its a good deal and worth looking into. This of course is only available in USA
