Keep looking at the batteries,when i last looked they still worked out more expensive than buying electricity.But that was before all the rises we have had since,should be at least equal now (unless batteries have gone up massively )We changed to British Gas in September as E-on were putting prices up massively. Now On a three year contract paying 19p and a standing charge of 30p. Thought I was doing well but the smart meter is too smart for its own good - had some big bills in November and December. Looking at batteries for our solar but doesn’t look promising. Seems daft we have this solar array which electricity is robbed from but we pay through the nose for it back.
