The current E7 fixed tarrif is about to end so have been digging about for a new contract/supplier. Came across Ebico's Night Owl tarrif, slightly raised peak cost, quite high standing charge but offset by free off peak lecky. You have to have, or agree to have, a Smart Meter fitted. If you have an E7 meter they want monthly readings but that is only temporary until the Smart Meter is fitted. If there is no signal to enable the Smart Meter to work I think you can stay on monthly readings.
The meters are in a small windowless, thick stone walled room, I had hoped that there would be no siganl in there but having waved a mobile phone in network scan mode next to the meters, there is a signal from all four networks. B-(
This is the first tarrif I've come across that uses the Smart Meter technology to half give some real benefit to the customer. Of course they, or any other supplier, could offer the same thing using the existing dumb E7 meters, if they wanted to.
It would be a genuine £400+/year saving for us, that almost tips the balance of having a Smart Meter for me but not for SWMBO'd (guess who doesn't pay the bill...). So E.ON have got us for the next 12 months on their "Go Online 1 year v8", DD and paperless tarrif(*1) which works out the same as the about to expire Scottish Power "Online Fixed Saver March 2018 v2". Everything else the comparison sites spewed up(*2) involved a real annual increase of between £120 and £440.
(*1) 15.404 p/kWHr Day, 7.004 p/kWHr night, 16.42 p/day standing charge (inc 5% VAT).
(*2) Including the ones that the comparision site couldn't do an online switch to.
