Op is based in London so creating mining farm is UK will be a bit problematic due to high energy costs.
I'm going to move/repost something I wrote several months ago in regards to coin mining in London, UK. My original post was in the thread related to the then new Bitmain miner and didn't gather any responses because it happened to be far off the main topic of that thread. Maybe here in this thread we will get better discussion going?
Location - London, I doubt any mining farm could be located there
I don't know anything about this particular company. But I do happen to have some fresh information about the real-estate/property developers in Greater London area. There is plenty of freshly build/renovated residential and commercial locations that are looking for a buyer without any current tenants. Developers are again resorting to having fake occupancy by letting trustable people to live and use the facilities free of rent&utilities. Conditions typically are: be personally known to trusted people in the construction business, be able to move out on a very short notice (few days at most), be trusted and capable of leaving the property in the "as new" condition, don't look and behave like a chav.
The holy grail of the Bitcoin mining is free electricity. Paradoxically, it is easiest to get it in the areas that normally have very high rents and costs of utilities. You won't get it on the regular commercial/residential terms, only as a temporary fallback financed by the developers/bond holders/speculators. Certainly, you won't find them advertised anywhere.
From my broader experience I'm pretty sure that such conditions aren't limited to London, UK. So keep your eyes open for opportunities like that in the city near you.
Again, the above was a general information, not specific to any particular offer discussed above.
In the months passing since then I have one more data point: certain woman artist moved her ceramic workshop from far-our rural England to rather prestigious London location, including rather large custom electric kiln. She had
lowered her monthly expenses taking advantage of the promotional deal offered by the property developer management. Obviously art studio isn't industrial-size coin mining, but is quite close as far as practical incidentals.
