Actually, UK electricity rates for new business contracts are currently coming in around £0.85 - £0.90 per kWh, which is around $1.00 per kWh.
An S19 Pro 100T generates around £5.86 worth of Bitcoin per day, and will cost £60.18 to generate that £5.86 of Bitcoin (at assumed rate of £0.85), for a total
loss of £54.32 per day, per S19 100T!
So unless you have free electricity, or have a current contract with very low rates, UK is not the place to be thinking about mining.
