Nest UK - what temperature do you set?

[nonamefortoday]

Hi, I'm after the temperature people set to warm up their homes using the best thermostat in the UK. In the winter I set mine to 22c but the house is cold, can set it to 24 an the temperature in the house is good, however the bill shoots up.

I wish Nest was compatible in my country.
