That looks quite decent at first glance. Somewhere your house seems to be losing too much heat; perhaps a ventilation system is pulling it all out? Have you ever looked for thermal bridges? 6 people also need relatively a lot of energy for hot water preparation, depending on showering/bathing habits that can be quite costly. How much (cold) water consumption do you have per day/week/month? That already allows for rough conclusions even if you don’t have a heat meter for hot water.

We don’t have ventilation.
Cold bridges. I would need a thermal imaging camera for that.

The two smallest ones just get bathed now and then.

You can also buy a laser infrared thermometer for about 50 euros and when it's below freezing outside, walk around the house with it to check critical points (window and door connections, seals, patio or platform connections to the house, etc.). No matter how inaccurate such a device is: it will show you tendencies in any case. Is it noticeably warmer somewhere than on the exterior wall? The same applies to the attic, if available. Is heat "creeping" out of the house anywhere? But as mentioned before: hot water demand for 6 people should not be underestimated either.

There is no attic. I can borrow a thermal imaging camera from our company. Let's see what I discover.
