Many thanks for your reply. Just in the last couple of weeks we’ve been able to fit a separate switching circuit as you quite rightly suggested. Since we moved in I’ve been taking a weekly reading to understand our usage and as soon as the switching circuit has been installed we are using a lot higher percentage of low peak electricity, as expected. Just an asside, OVO tried to fit a correct meter four times and did not know their insallers could not supply an automatically switching meter.
Thanks for your help.
