>heating an office space with 500+ people is much more efficient than heating 500 individual houses

Citation needed. I would argue its very hard to make any general statement about this. In my case the office is much more wasteful than the space I use for remote work for a multitude of reasons.

I said I'm not convinced, it obviously isn't a general thing.

A friend of mine spends 500+ euros per month on gas for heating since he works from home, no way on earth his office uses 500 per person and per month on heat

A 2kW electric heater can heat up any reasonable size office room up to a temperature where you are going to have to strip to your underwear (or turn it off) in under an hour in my experience.

Even if it's on 8 hours a day constantly, 5 days a week, 4 weeks a month that's 320kWh or just over £100 a month at UK energy prices.

In comparison, we have a 1600 sq ft home and only have $50 USD gas bills lately. It's definitely been higher (at least double), but we've been learning to live with a colder thermostat.

Granted this is the US, and natural gas is considerably cheaper here than in a lot of countries in Europe right now, so you probably need to at least double what I said anyway for Europe.

Is that € 500 for just the working hours? Because homes are also generally heated for other uses than work. Those reasons don't go away if you work at the office. If you've got a spouse working from home, or kids coming from school, that house is going to be heated anyway.

I work from home full time, my gas bill is a fraction of that (~GBP100/month), and that's even accounting for the crazy energy cost increases we've seen in the UK.
