Per year. And assumes electricity prices won't go up.

It took me half-an-hour to grab the CSV files from my monitoring, a write a scrap of Python to work out the difference in prices, then double-check my workings.

I'm happy with that ROI.

What would your advice be to someone with no electric car, no solar battery, no solar panels, and no subsidy available on them? Is the smart tariff still a good deal?

Depends on your usage patterns. If your job means you always get home after 7pm, or if you cook with gas, then it may still be worth it.

£60/yr would be a good saving for a supplier switch, the comparision and admin from which could easily add up an hour's work. A good ROI indeed!

What do you use for monitoring your mains supply?

The smart battery provides the monitoring. It is literally a clamp on the meter to monitor import and export, and one on the solar panel feed to measure generation. Small bit of Python to grab it ever 10 minutes.
