That is quite a setup for the UK. I have gone for the frugal option, so that means I have a vehicle fleet that consists of one naturally aspirated bicycle augmented by electric train for longer journeys. In Scotland the trains run with electricity from wind farms, so I am okay with that.

However, from how you describe it, you are getting lower costs than me! My electricity bill is lower than the standing charge, but this adds up to more than what you are paying. Train fares also seem to be costing me more, although I have done well out of compensation for late trains recently, so my trips to the south of England are averaging out at around £100 for the return journey.

I am beginning to question my life choices. Frugal was the wrong way to go. Why do I need this cardiovascular exertion when I could be getting around for less in a two-tonne EV?

I think I missed the boat. Getting a feed in tariff is far from given these days and the government grants for solar ended about a decade ago.

You still don't pay VAT if installed by an MCS accreddited installer.

Also commute by train, and yeah, it's not cheap. My season ticket is £11k a year!
