Understanding Your Business Gas Consumption
Every UK business using gas for heating, hot water, or industrial processes needs to understand their gas usage to control costs effectively. At ScaleX Technology, we help businesses optimise their energy consumption, so we’ve created this comprehensive guide to managing your commercial gas usage.
Why Monitoring Business Gas Usage Matters
✅ Cost control – Identify and reduce wasteful consumption
✅ Budget accuracy – Predict future bills with confidence
✅ Sustainability – Lower your carbon footprint
✅ Compliance – Meet energy reporting requirements
How Business Gas is Measured
Measurement Units
- Kilowatt hours (kWh) – Standard unit for gas billing
- Cubic metres (m³) – What your meter records
- Therms – Older measurement still used by some suppliers
Conversion from m³ to kWh involves multiplying by volume correction and calorific value factors
Typical Business Gas Consumption
| Business Type | Annual Usage | Monthly Cost* |
|---|---|---|
| Small Office | 5,000-15,000 kWh | £150-£450 |
| Restaurant | 30,000-75,000 kWh | £900-£2,250 |
| Medium Workshop | 50,000-150,000 kWh | £1,500-£4,500 |
| Large Factory | 500,000+ kWh | £15,000+ |
*Based on average 2024 business gas prices of 10p/kWh including VAT
