Hi Bloggsy, I was with EDF, had a smart meter, but only found out 10 months into a year contract that the electric was not connecting with their system so had not been changed to the cheap tariff. The SMART meter was rectified having insisted on an engineer visit. On 9 May I switched to Octopus Go. Within 2 days I was connected so could take advantage of the 4 hour cheap rate. I then immediately applied for Go Faster, still 4 hours, but starting at 9.30 so that I could use the cheaper tariff for washing machine and dish washer. Within 6 days this had been granted at my selected time slot. I have nothing but praise for Octopus and thoroughly recommend them. Having said that I am at the opposite end of the UK to you.
