My electricity use has dropped dramatically.

Thats good , just in time for the price hike in October 

On the credit ........these power companies always overcharge on the direct debit tariffs though the ever changing price caps don't help in seeing where you are at  .I can't say I take a lot of notice of mine but did check a couple of months back and found I was over £600 in credit which they repaid as soon as I asked for it back . Makes you wonder how much cash these companies are actually holding.

Checked on my electricity usage online yesterday. I am near £200 in credit. That has happened since the old hot water tank and immersion heater were both replaced at a cost of £600. (The old tank was "only" 40 years old.) It won't take long to recoup the cost of the new tank.
