I have e had a solar system for about 13 years, I decided before. investing in an EV I would have a 10kw battery system installed. when the salesman told me that he had the Octopus Go tarriff and how fair the prices were I rang to and joined your standard rate before being able to switch after 45 days. But was told that tarriff was not available anymore UNLESS I had an EV. many company's offer a split tarriff but I am concerned that your policy has changed and the salesman did not know, he has had the tarriff for many years for his battery system but does not have an EV. Can you help here please.
