Mining requires cheap electricity. Most large scale mining occurs in areas with surplus hydro electricity. Think western China, Washington state in USA, Georgia or parts of Canada.
Any mining in the UK would be very small scale by hobbyists or people with free electricity (renters of apartments and so on). UK is not likely to be considered by serious mining investors.
For Bitcoin, serious investors are after bulk electricity at under 4 cents per kWh. This normally means near a hydro dam with surplus power.
You CAN mine without cheap electric.
You are going to be hard put to mine PROFITABLY for very long without it, and if you want to ever earn your money back on the mining gear you buy you better have VERY cheap electric or cheap electric and got one heck of a good deal on used gear (or price-war gear).
I doubt there are ANY large farms in the UK, and not a lot of miners in general.
