How Much Does It Cost to Run a Crypto Mining Rig in the UK? (2026)
A mining rig runs flat out around the clock. Even a single-GPU setup at 500 watts uses more electricity than most whole households, and an ASIC miner at 3,000 watts uses as much as a dozen fridges.
A typical crypto mining rig (1,500 W) costs £0.39 per hour, or about £284.26 per month at 24 hours a day in the UK. Expensive to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low 500 W | £0.13 | £3.16 | £94.75 | £1,153 |
| Typical 1,500 W | £0.39 | £9.48 | £284.26 | £3,458 |
| High 3,500 W | £0.92 | £22.11 | £663.26 | £8,070 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 24 h/day ≈ 13,140 kWh per year.
One hour of a crypto mining rig (1.5 kWh) is the same electricity as
- 8.3km in an electric car
- 15hours of TV
- 33hours of a laptop
- 167hours of an LED bulb
In the UK, with electricity at 26.3p per kWh (source: Ofgem price cap 1 Oct–31 Dec 2026, 2026-10), a typical crypto mining rig costs £0.39 per hour and about £3,458 per year at 24 hours a day. Each £1.00 of electricity buys roughly 2.5 hours of use.
How to lower the cost of running a crypto mining rig
- Calculate the electricity cost per day before anything else. It decides whether mining makes money at all.
- Undervolt GPUs. It often cuts power by 20 to 30 percent with little hash rate loss.
- Vent the heat outdoors in summer. Cooling the room adds to the bill.
