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 £280.80 per month at 24 hours a day in United Kingdom. Expensive to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (500 W) | £0.13 | £3.12 | £93.60 | £1,139 |
| Typical (1,500 W) | £0.39 | £9.36 | £280.80 | £3,416 |
| High (3,500 W) | £0.91 | £21.84 | £655.20 | £7,972 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 24 h/day ≈ 13,140 kWh per year.
In the UK, with electricity at £0.26 per kWh (source: Ofgem price cap 1 Jul–30 Sep 2026, 2026-07), a typical crypto mining rig costs £0.39 per hour and about £3,416 per year at 24 hours a day. Each £1.00 of electricity buys roughly 2.6 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.
