Great site, thanks for all your hard work. Look forward to the update.
After a faulty oil tank and much agonising, we had an expensive Thermaflow wet electric heating system with water storage installed last July. E.on converted our meter to E10.
We are paying 16.89p peak and 7.91p off peak. I am monitoring the results very carefully and it looks as if we will save around 20% on our total fuel bill if we are disciplined with timings.
So far E.on have been very helpful (although not the cheapest) and the billing is accurate and well explained. We will review the situation when we have a full year’s experience.
