Mine is on continuously all year round, set at 20.5c
I’m pretty much housebound and my Autistic adult son never goes out on his own. So apart from the odd trip out we’re indoors 24/7.
Electricity usage is fairly constant throughout the year, gas varies from 1KwH per week up to 10-13KwH in the winter when the heating is on a lot more.
I pay £76 per month and am usually still in credit by the end of the year.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
