Average Chest Freezer Wattage by Size
Estimated average running wattages for common chest freezer capacities. Actual consumption varies by energy efficiency rating (e.g., A+++ vs older models).
| Freezer Size | Avg. Running Wattage | Est. Yearly Cost (at 28p/kWh) |
|---|---|---|
| Small (100 Litres) | ~100 W | ~£30 – £40 |
| Medium (200 Litres) | ~150 W | ~£45 – £55 |
| Large (300 Litres) | ~200 W | ~£60 – £75 |
| Extra Large (400+ Litres) | ~250 W | ~£75 – £95 |
Freezer Energy FAQ
Everything you need to know about chest freezer electricity usage, efficiency, and cost-saving tips.
On average, running a standard chest freezer in the UK costs between £35 and £60 per year. This depends on the freezer’s size, energy efficiency rating, ambient room temperature, and your specific electricity tariff.
No, chest freezers are generally very energy-efficient. Because cold air sinks and the lid opens from the top, they retain cold air much better than upright freezers, meaning the compressor runs less frequently and uses less electricity.
The duty cycle refers to the percentage of time the compressor is actively running. For a well-maintained chest freezer in a cool environment, the duty cycle is typically between 30% and 50% (roughly 7 to 12 hours per day).
Keep the freezer in a cool, well-ventilated room. Keep it well-stocked (frozen items help retain cold), defrost it regularly to prevent ice buildup, ensure the door seal is airtight, and avoid opening the lid unnecessarily.
