Success

The new smart electricity and gas meters were installed today without any major issues, and now seem to be working.  My little nagging device is now available to torture me about the magnitude of our costs regularly.

Not sure how helpful that will be. 

We switched all the lighting to LEDs years ago, we have smart control for the heating, we use appliances sensibly - not a lot of scope for cutting!

In other news I am now on day 3 of an unpleasant stomach bug of some sort.
