154 m³ = 1,728 kWh. Your bill for 31 days is about 182.1 €, an all-in 0.105 € per kWh. A January bill like this suggests roughly 10,900 kWh a year.

Conversion steps
| Step | Value |
|---|---|
| Units used | 154 m³ |
| Volume correction | × 1.02264 = 157.49 m³ |
| Calorific value | × 39.5 MJ/m³ = 6,221 MJ |
| Convert to kWh | ÷ 3.6 = 1,728 kWh |
| Energy charge | 1,728 kWh × 0.1 = 172.8 € |
| Standing charge | 31 days × 0.3 = 9.3 € |
| VAT | 0% = 0 € |
| Total | 182.1 € |
- kWh = m³ × volume correction × calorific value (MJ/m³) ÷ 3.6. UK suppliers must use this formula; most of Europe applies an equivalent “Zustandszahl” × “Brennwert”.
- Annual estimate uses a typical temperate-climate heating profile (January ≈ 15% of yearly use, July ≈ 2.5%). Gas used only for cooking/hot water is much flatter.
