ᐅ Gas and electricity consumption in new construction

Hello everyone,

We are planning to switch our electricity and gas providers. To start: yes, I know you can’t generalize for every household, so I’m interested in average values. Here’s our situation:
- House size: 163 sqm (1755 sq ft)
- No basement
- 2 adults
- 1 child (1.5 years)
- Underfloor heating

For average electricity consumption, we are using local comparison websites. They suggest about 4250 kWh per year.
However, we’re having more trouble estimating gas usage. What values have you used, and how did that work out for you? Did you tend to underestimate or overestimate? The recommendations for gas vary widely. Some sources say 20,000 kWh for a single-family home with 4 people, others suggest 30,000 kWh for a single-family home with 2 people.

On the one hand, I don’t want to be unnecessarily financially burdened month to month, but on the other hand, I want to avoid a large additional payment after a year.
Does anyone have experience or advice on what is a reliable approach or good estimates to use?

I understand it depends on individual living situations—some like it cozy warm all year, others only turn the heating on when it’s at 0°C (32°F). I’m not looking for exact figures, but rather experiences regarding typical annual consumption.

That's really like a hand in a glove.
Just estimate for the first year, and then there will be either an additional payment or a refund. Either way, it comes out the same in the end.

You yourself say it's impossible. So how are outsiders supposed to estimate your consumption if you can't even manage it yourself?

In our new build, with two people, the electricity consumption is about 1500 kWh/year. The consumption portals suggest 3500 kWh/year to me...

I can't say anything about gas, as we have a ground source heat pump (own meter).

I never claimed otherwise, but please just read the post again. Thank you.

The same applies here, just take another look at my initial post. Furthermore, it might help if someone has a similar floor area, also 2 adults living with 1 child. Normal heating conditions. Consumption of 18,000 kWh per year. That’s a reference point.
Even though everyone probably interprets “normal heating conditions” differently...

If out of maybe 10 responses, all consumption values are between 15,000 and 20,000 kWh, that gives a useful benchmark. But if those 10 responses range from 1,000 to 500,000 kWh, it gets much harder. And that’s all I’m hoping for—to get a rough idea.
And I’m not going to sue anyone if my consumption ends up 1 kWh higher.

We have 156m² (1680 sq ft) of living space and are two people. Heating is rather economical, maintaining 20-21°C (68-70°F) in all living areas and 21-22°C (70-72°F) in the bathroom. Electricity consumption is about 2,500 kWh and gas consumption is exactly 10,000 kWh. With a child, of course, these numbers will increase somewhat.

It's really just guesswork. How big is your bathtub, and how often do you take baths? How warm are the rooms? Is there a wood stove? What energy standard does the building follow? There are simply too many variables.

Just take the average value and add 20% to be on the safe side. Then next year, you might be happy to receive a big refund.

Monthly gas costs in a new build shouldn’t exceed more than 60-80€ (about 65-87 USD).

Last year, with four people, 190 sqm (2,045 sq ft) plus a heated conservatory, about 24,000 kWh.

Built in 1974, conservatory added in 1984.

New build? Anything over 10,000 would be very, very wrong.
