PennyPerHourHow much does a slushie machine cost to run?
A compressor-based home slushie machine typically draws 130–200 watts while freezing. In one independent test, a full batch took about 35 minutes and used around 0.08kWh, which is about 2.1p at 26.32p/kWh. Keeping it running afterwards uses around 40W, roughly 1.1p an hour.
Electricity 26.32p/kWh, gas 7.97p/kWh (Ofgem cap, 1 October to 31 December 2026). Typical figures.
Slushie machine running costs
| Use | Energy | Cost |
|---|---|---|
| Freeze one batch (~35 min) | 0.08kWh | 2.1p |
| Keep slush frozen, per hour (~40W) | 0.04kWh | 1.1p |
| Party: 1 batch + 6 hours holding | 0.32kWh | 8.4p |
| Every weekend for a summer (13 parties) | 4.2kWh | £1.09 |
Based on measurements of a compressor frozen-drink maker reported by Galaxus. Your model and ingredients will vary. Starting with chilled ingredients shortens freezing time.
Compared with other ways to make frozen treats
- Blender with ice (1,000W for 1 minute): about 0.4p a jug, but the texture is icier and it melts faster.
- Ice cream maker with a pre-frozen bowl: the machine itself uses very little (around 12W), but the bowl needs a day in your freezer.
- Freeze-then-process machines (around 800W for a few minutes): a couple of pence of electricity per tub, plus freezer time for the base.
- Squeeze slushie cups: no electricity, but they only make one small drink at a time.
Tips for cheaper slush
- Chill your mix in the fridge first. Starting at 5°C instead of room temperature cuts freezing time.
- Get the sugar right. Most machines need a minimum sugar content to make slush instead of solid ice, so check the manual before using diet drinks.
- Switch off when the party winds down. Holding temperature for hours is where most of the cost comes from.
- Keep it out of direct sun and leave space around the vents so the compressor isn't working harder than it needs to.
What to look for
- Compressor cooling (no pre-freezing needed) if you want slush on demand.
- Capacity: around 2–2.5 litres makes roughly 8–10 drinks.
- Presets for slush, frappé, milkshake and frozen cocktails.
- Removable, dishwasher-safe parts. Sugary drinks get sticky fast.

How long does a home slushie machine take?
Typically 15 to 60 minutes depending on the drink, its starting temperature and its sugar content.
Can I use diet or sugar-free drinks?
Many machines need a minimum sugar level to form slush. Check your manual: some have settings for low-sugar drinks.
