Maybe I will take another look fwippers – I have a smart meter so took data from history and put it on a spreadsheet – the two things that meant it didn’t work for us is not wanting to have any appliances running after midnight and the increased day rate – I ran the same for both OVO – who I am currently with and octopus – maybe some of the rates have changed – easy enough to change on the sheet.
Our central heating is gas and we use the same supplier for both.
Which adds another variable – but I will look again – hope it all works well for you!
